Summary of the Invention

Problems to be Solved by the Invention

[0004] When a customer dies, property such as real estate owned by the customer is inherited. However, simply checking the registration information of real estate before inheritance registration cannot determine whether the real estate is estate-occurring real estate, that is, real estate for which inheritance has occurred or real estate for which inheritance is likely to occur.

[0005] The present invention has been made in view of the above circumstances, and one of its objectives is to provide an estate-occurring real estate estimation system, an estate-occurring real estate estimation method, and a program that can accurately estimate estate-occurring real estate, that is, real estate for which inheritance has occurred or real estate for which inheritance is likely to occur.

Means for Solving the Problems

[0006] (1) The inheritance-occurring real estate estimation system according to the present invention includes: an owner identification means for each of a plurality of registration pieces stored in a registration information storage means, which identifies the latest owner of the real estate associated with the registration piece as shown in the registration piece; a determination means for determining whether there is a particular registration application information among a plurality of registration application information stored in a registration application information storage means, which is a registration application information pertaining to a real estate associated with a particular registration piece that is one of the plurality of registration pieces, and which indicates that the purpose of the registration is the transfer of ownership through inheritance; and an inheritance-occurring real estate estimation means for determining, when it is determined that the particular registration application information exists, a real estate associated with a different registration piece that has one or more owners in common with the particular registration piece, which is an inheritance-occurring real estate that has been inherited or is highly likely to be inherited.

[0007] (2) In the inheritance property estimation system described in (1), if there are multiple owners identified with respect to the registration information of interest, the inheritance property estimation means may estimate as the inheritance property a property that is associated with registration information different from the registration information of interest, where there are multiple owners identified and all of the multiple owners are the owners of interest.

[0008] (3) In the inheritance property estimation system described in (1), if there is one owner identified with respect to the registration information of interest, the means for estimating inheritance property may estimate as the inheritance property a property associated with registration information different from the registration information of interest, where there are multiple owners identified and any of the multiple owners is the owner of interest.

[0009] (4) In the inheritance property estimation system described in (1), if there are multiple owners identified with respect to the registration information of interest, the means for estimating inheritance property may estimate as the inheritance property a property that is associated with registration information different from the registration information of interest, where there is one owner identified and that owner is one of the multiple owners of interest.

[0010] (5) In the inheritance property estimation system described in (1), the inheritance property estimation means may estimate as the inheritance property if there are multiple owners identified with respect to the registration information of interest, and any of the multiple owners identified is one of the multiple owners of interest, and the property is associated with registration information different from the registration information of interest.

[0011] (6) The inheritance property estimation system described in any of (1) to (5) may further include a means for associating the above-mentioned registration application information with the registration information of the property obtained after the date of receipt of the above-mentioned registration application information.

[0012] (7) The method for estimating inherited real estate according to the present invention includes the steps of: an owner identification means identifying the latest owner of real estate associated with a registration information, as shown in the registration information, for each of a plurality of registration information stored in the registration information storage means; a determination means determining whether there exists a particular registration application information among a plurality of registration application information stored in the registration application information storage means, which is a registration application information relating to a particular registration information that is one of the plurality of registration information, and which indicates that the purpose of the registration is the transfer of ownership through inheritance; and an inherited real estate estimation means, if it is determined that the particular registration application information exists, estimating as inherited real estate that has been inherited or is highly likely to be inherited real estate that has been inherited, a real estate associated with a registration information different from the particular registration information, where one or more owners are common to the particular registration information.

[0013] (8) The present invention is a program that causes a computer to perform the following steps for each of a plurality of registration information stored in a registration information storage means: identify the latest owner of the real estate associated with the registration information as shown in the registration information; determine whether there is a particular registration application information among the plurality of registration application information stored in a registration application information storage means that pertains to a particular registration information which is one of the plurality of registration information, and indicates that the purpose of the registration is the transfer of ownership through inheritance; and if it is determined that the particular registration application information exists, estimate that a real estate associated with a different registration information from the particular registration information, in which one or more owners are common to the particular registration information, is a real estate in which inheritance has occurred or a real estate in which inheritance is highly likely to occur.

Mode for Carrying Out the Invention

[0015] Hereinafter, an embodiment of the present invention will be described in detail based on the drawings.

[0016] FIG. 1 is a functional block diagram showing an example of the functions implemented in the succession-occurring real estate estimation system 10 according to the present embodiment. Note that in the succession-occurring real estate estimation system 10 according to the present embodiment, it is not necessary to implement all of the functions shown in FIG. 1, and functions other than those shown in FIG. 1 may be implemented.

[0017] As shown in FIG. 1, the succession-occurring real estate estimation system 10 according to the present embodiment functionally includes, for example, a registration information storage unit 20, a registration application information storage unit 22, an owner grouping unit 24, a registration information acquisition unit 26, a succession-occurring real estate estimation unit 28, and an association unit 30.

[0018] The succession-occurrence real estate estimation system 10 may be configured by a known computer including, for example, a CPU, a memory, a communication interface, an input device, and a display. And the functional blocks shown in FIG. 1 are realized by executing a succession-occurrence estimation program in the succession-occurrence real estate estimation system 10 which is a computer. The succession-occurrence estimation program may be stored in various computer-readable information storage media such as a semiconductor memory, and loaded from the medium into the succession-occurrence real estate estimation system 10. Alternatively, it may be downloaded to the succession-occurrence real estate estimation system 10 via a data communication line such as the Internet.

[0019] In this embodiment, the registration information storage unit 20 stores, for example, a plurality of pieces of registration information. For example, data of registration information may be acquired in advance from a registration information providing service by an entity such as the General Incorporated Association of Civil Law Affairs via a communication interface. And the registration information data which is the acquired data of registration information may be stored in the registration information storage unit 20.

[0020] FIG. 2A and FIG. 2B are diagrams showing an example of registration information data. It is assumed that one piece of registration information data is represented by the whole of FIG. 2A and FIG. 2B.

[0021] The registration information data according to this embodiment is associated with information on all matters of real estate registration for one piece of real estate. In FIG. 2A and FIG. 2B, the registration information data associated with the information on all matters of real estate registration of land is shown. As shown in FIG. 2A and FIG. 2B, the registration information data according to this embodiment includes acquisition date and time data, title section data, and right section (Section A) data. In the registration information data, erased values are underlined.

[0022] The acquisition date and time data shown in FIG. 2A is data indicating the date and time when the registration information data was acquired from the registration information providing service.

[0023] The title section data shown in Figure 2A corresponds to the content of the title section of the corresponding real estate registration. The title section data includes display type data, preparation date data, real estate number data, map number data, boundary identification data, and location data.

[0024] The display type data is the data indicating the type of real estate, written in parentheses to the right of the title section of the complete real estate registration. The preparation date data, real estate number data, map number data, boundary identification data, and location data are data that indicate the contents of the preparation, real estate number, map number, boundary identification, and location sections of the complete real estate registration, respectively.

[0025] Furthermore, the registration information data associated with the complete real estate registration information for a building includes location map number data, which indicates the location map number described in the title section of the complete real estate registration, instead of map number data.

[0026] Furthermore, the title section data includes one or more combinations of land parcel number data, land category data, land area data, and cause and date [registration date] data.

[0027] The land number data, land category data, land area data, and cause and date [registration date] data are data that represent the contents of the land number, land category, land area, cause and date [registration date] described in the title section of the complete real estate registration, respectively.

[0028] Furthermore, for registration information data associated with the complete real estate registration information for buildings, the title section data will contain one or more combinations of house number data, type data, structure data, floor area data, cause and date [registration date] data, instead of the combination of land number data, land category data, land area data, and cause and date [registration date] data. The house number data, type data, structure data, floor area data, and cause and date [registration date] data are data that represent the contents of the house number, type, structure, floor area, cause and date [registration date] in the title section of the complete real estate registration information, respectively.

[0029] The rights section (Section A) data shown in Figure 2B corresponds to the content of the rights section (Section A) of the corresponding real estate registration. The rights section (Section A) data includes one or more combinations of rank number, purpose of registration data, acceptance date data, acceptance number, rights holder and other matters data. Hereinafter, the combination of rank number, purpose of registration data, acceptance date data, acceptance number, rights holder and other matters data will be referred to as Section A element data. The rights section (Section A) data shown in Figure 2B includes three Section A element data.

[0030] The rank number and registration purpose data are data indicating the rank number and the content of the registration purpose in the rights section (Section A) of the complete real estate registration, respectively. The acceptance date data and acceptance number are data indicating the acceptance date and the content of the acceptance number included in the rights section (Section A) of the complete real estate registration, respectively. The rights holder and other matters data are data indicating the content of the rights holder and other matters in the rights section (Section A) of the complete real estate registration.

[0031] Furthermore, the registration information data according to this embodiment may include the rights section (Section B) corresponding to the contents of the rights section (Section B) of the corresponding real estate registration, and joint collateral register data corresponding to the contents of the joint collateral register of the corresponding real estate registration.

[0032] In this embodiment, the registration information storage unit 20 is assumed to store registration information data for a predetermined prefecture (for example, Prefecture A).

[0033] In this embodiment, the registration application information storage unit 22 stores, for example, multiple registration application information. Here, registration application information data corresponding to the contents of the real estate registration receipt book managed by the Legal Affairs Bureau may be obtained in advance via a communication interface from a registration application information data provision system in which registration application information is registered as data. The obtained registration application information data may then be stored in the registration application information storage unit 22.

[0034] Figure 3 shows an example of registration application information data. The registration application information data illustrated in Figure 3 is associated with one real estate registration application. The registration application information data according to this embodiment includes reception date data, reception number, property identification data, application unit data, registration purpose data, usage data, and parcel data.

[0035] The acceptance date data is, for example, data indicating the acceptance date of the registration application associated with the registration application information data.

[0036] The reception number is, for example, a number assigned according to the order in which the registration application was received in the year that the registration application associated with the registration application information data was made.

[0037] Property identification data is, for example, data used to identify the real estate subject to the registration application that is associated with the registration application information data. As shown in Figure 3, property identification data includes prefecture name data, city / ward / town / village name data, district name data, sub-district name data, and land number / house number data.

[0038] The prefecture name data, city / ward / town / village name data, Oaza / town name data, sub-district name / block data, and land number / house number data are, respectively, data indicating the prefecture name, city / ward / town / village name, Oaza / town name, sub-district name or block, and land number or house number of the real estate subject to the registration application.

[0039] The land parcel number and house number data indicates the land parcel number of the property in question if the property subject to the registration application is land. Furthermore, if the property subject to the registration application is a building, the land parcel number and house number data indicates the house number of that building.

[0040] In this embodiment, the location of the real estate subject to the registration application, which is associated with the registration application information data, can be identified based on the property identification data. For example, a string formed by concatenating the values ​​of prefecture name data, city / ward / town / village name data, district name data, and sub-district name data corresponds to a string representing the location of the real estate.

[0041] Application unit data indicates, for example, whether the registration application associated with the registration application information data was made as a single application or as a series of applications. This corresponds to the entries "single," "series," and "continuous" in the real estate registration receipt book. The application unit data of the registration application information data associated with the first registration application in a series of applications will be set to the value "series." The application unit data of the registration application information data associated with the registration application submitted together with that application unit data will be set to the value "continuous." In addition, the application unit data of the registration application information data associated with a single application will be set to the value "single."

[0042] The registration purpose data is, for example, data indicating the purpose of the registration application associated with the registration application information data. Note that the string value of the registration purpose data included in the registration application information data does not necessarily have to match the string representing the registration purpose in the real estate registration receipt book associated with the registration application information data.

[0043] The usage data is, for example, data indicating the usage (type) of the real estate related to the registration application, which is associated with the registration application information data. If the real estate related to the registration application is land, the value "land" is set in the usage data. If the real estate related to the registration application is a building, the value "building" is set in the usage data. If the real estate related to the registration application is a condominium unit, the value "condominium unit" is set in the usage data.

[0044] The external parcel data is data that indicates the existence and number of properties for which registration applications have been filed in a single registration application, along with the properties identified by the property identification data. Hereafter, registration applications for two or more properties in a single registration application will be referred to as a consolidated application.

[0045] If there are other properties included in the bulk application, the registration application information will record information about the other properties, such as "External 1" or "External 2." Here, "External 1" means that there is one property included in the bulk application along with the property identified by the property identification data. "External 2" means that there are two properties included in the bulk application along with the property identified by the property identification data.

[0046] In this embodiment, for registration application information in which outer parcel information is recorded, a value of 1 or more is set for the outer parcel data. In this embodiment, for example, the outer parcel data of registration application information data corresponding to registration application information in which outer parcel information of "Outer 1" is recorded will be set to a value of 1. Also, the outer parcel data of registration application information data corresponding to registration application information in which outer parcel information of "Outer 2" is recorded will be set to a value of 2. Furthermore, in this embodiment, the outer parcel data of registration application information data in which outer parcel information is not recorded will be set to a value of 0.

[0047] Furthermore, in this embodiment, the registration application information data stored in the registration application information storage unit 22 is associated with each other in relation to the registration application information data related to the registration applications that have been submitted in succession. For example, the registration application information data related to the registration applications that have been submitted in succession is assigned the same succession application group ID.

[0048] For example, the same consecutive application group ID may be assigned to registration application information data where the value of the application unit data is "sequential," and to one or more registration application information data where the value of the application unit data is "consecutive," and whose reception number follows that registration application information data.

[0049] In this embodiment, the owner grouping unit 24 identifies, for example, the most recent owner of the real estate associated with each of the multiple registration information records stored in the registration information storage unit 20, as indicated in the registration information. Here, for example, the owner grouping unit 24 identifies the most recent owner of the real estate associated with the registration information data, as indicated in the registration information data, based on the registration information data. However, if the acquisition date and time of the registration information data is old, the most recent owner of the real estate associated with the registration information, as indicated in the registration information data of interest, is not necessarily the current owner of the real estate.

[0050] The owner grouping unit 24 then groups the multiple registration information stored in the registration information storage unit 20 according to the identified owner. For example, the owner grouping unit 24 performs a process to associate an owner group ID with each of the multiple registration information data.

[0051] In this embodiment, for example, a process is performed to associate an owner group ID with all of the multiple registration information data stored in the registration information storage unit 20. Here, as an example, an example of the process flow for identifying the latest owner of the real estate indicated in the registration information data, which was acquired at 9:12 AM on April 1, 2018, based on the rights section (Section A) data included in the real estate registration information data shown in Figure 2B, and associating an owner group ID with the registration information data will be explained with reference to the flowchart illustrated in Figure 4. Hereinafter, the registration information data to which an owner group ID is associated will be referred to as the grouping target registration information data.

[0052] First, the owner grouping unit 24 generates initial owner management data, as illustrated in Figure 5A (S101). Owner management data is data associated with real estate. As shown in Figure 5A, the owner management data includes, for example, owner name data indicating the name (e.g., full name) of the owner of the real estate associated with the owner management data, owner address data indicating the address of the owner of the real estate, and ownership share data indicating the owner's share of the real estate. Initially, the value of the owner name data is "unknown", the value of the owner address data is "unknown", and the value of the ownership share data is 100%.

[0053] Then, the owner grouping unit 24 sets the value of variable N to 1 (S102). The owner grouping unit 24 then checks whether the value of the registration purpose data included in the Section A element data whose rank number is N contains the string "transfer" (S103).

[0054] If it is not included (S103:N), the process proceeds to S105. If it is included (S103:Y), the owner grouping unit 24 updates the owner management data based on the value of the registration purpose data included in the Class A element data with rank number N, and the rights holder and other matters data, which are included in the grouping target registration information data (S104). A specific example of the process shown in S104 will be described later.

[0055] Then, the owner grouping unit 24 checks whether N is the last rank number (S105). If N is not the last rank number (S105:N), the owner grouping unit 24 increments the value of N by 1 (S106) and proceeds to the process shown in S103.

[0056] If N is the last rank number (S105:Y), the owner grouping unit 24 identifies the latest owner of the real estate associated with the grouping target registration information data, as indicated in the grouping target registration information data, based on the latest owner management data (S107). A specific example of the process shown in S107 will be described later.

[0057] Then, the owner grouping unit 24 checks whether the owner identified in the process shown in S107 is the same as the registration information data to be grouped, and whether there is another registration information data to which the owner group ID is already associated (S108).

[0058] If one exists (S108:Y), the owner group ID associated with the other registration information data is associated with the registration information data to be grouped (S109), and the process shown in this example is terminated.

[0059] If it does not exist (S108:N), the process shown in this example is terminated by associating a new owner group ID with the grouping target registration information data (S110).

[0060] In the process shown in S104, for example, named entity recognition (NER) technology is used to check whether the value of the registration purpose data contains a string indicating a name or other designation.

[0061] If it is confirmed that the value of the registration purpose data does not contain a string indicating a name or other designation, then named entity recognition technology is used to extract a string indicating an address and a string indicating a name (e.g., name) from the rights holder and other matters data according to predetermined rules. For example, a combination of a string indicating an address and a string indicating a name following the string "owner" may be extracted. Alternatively, one or more combinations of a string indicating an address, a string indicating a share, and a string indicating a name following the string "co-owner" may be extracted.

[0062] Then, the owner management data for which the owner name data value is "unknown" is updated.

[0063] For example, in the rights section (Section A) data shown in Figure 2B, based on the Section A element data with rank number 1, the combination of the owner's address "B City C Town D124-1" and the owner's name "Mr. N" is extracted from the rights holder and other matters data. Based on this, the owner management data is updated from what is shown in Figure 5A to what is shown in Figure 5B. That is, the rights holder management data where the value of the owner's name data is "unknown", the value of the owner's address data is "unknown", and the ownership share data is "100%" is updated to the rights holder management data where the value of the owner's name data is "Mr. N", the value of the owner's address data is "A Prefecture B City C Town D124-1", and the ownership share data is "100%". In this way, a string with a predetermined string "A Prefecture" appended to the owner's address extracted from the rights holder and other matters data may be set as the value of the owner's address data.

[0064] Furthermore, based on the Section A element data with rank number 2, the combination of the owner's address "B City C Town D125-2", ownership share "1 / 2", and owner's name "M. O. O." is extracted from the rights holder and other matters data, as well as the combination of the owner's address "B City C Town D125-3", ownership share "1 / 2", and owner's name "M. P. K.".

[0065] Based on this, the owner management data is updated from what is shown in Figure 5B to what is shown in Figure 5C. Specifically, the rights holder management data where the owner name data value is "Mr. N," the owner address data value is "D124-1, C-cho, B-city, A-prefecture," and the ownership share data is "100%" is updated to the rights holder management data where the owner name data value is "Mr. O," the owner address data value is "D125-2, C-cho, B-city, A-prefecture," and the ownership share data is "50%", and the rights holder management data where the owner name data value is "Mr. P," the owner address data value is "D125-3, C-cho, B-city, A-prefecture," and the ownership share data is "50%".

[0066] If it is confirmed that the value of the registration purpose data includes a string indicating a name or other designation, the same process as described above will be used to extract the string indicating the address and the string indicating the name from the rights holder and other matters data using named entity recognition technology.

[0067] In this case, the owner management data is updated, and the name or other designation confirmed in the registration purpose data is set as the value of the owner name data.

[0068] For example, based on the Section A element data with rank number 3, "M. O

[0069] Based on this, the owner management data is updated from what is shown in Figure 5C to what is shown in Figure 5D. That is, the rights holder management data where the owner name data value is "Mr. O.", the owner address data value is "D125-2, C-cho, B-city, A-prefecture", and the ownership share data is "50%" is updated to the rights holder management data where the owner name data value is "R. Taro Qgawa", the owner address data value is "G24-1, F-cho, E-city, A-prefecture", and the ownership share data is "50%". In this example, the owner management data shown in Figure 5D becomes the owner management data used in the process shown in S107.

[0070] In the process shown in S107, based on the owner management data shown in Figure 5D, it is identified that there are two current owners as shown in the grouped registration information data. The name and address of one owner are identified as "Qgawa R Taro" and "G24-1, F-cho, E-shi, A-ken," and the name and address of the other owner are identified as "Mida P-ko" and "D125-3, C-cho, B-shi, A-ken."

[0071] The process for identifying the most recent owner is not limited to the methods described above. For example, if there is only one Section A element data in the rights section (Section A) data, the owner grouping unit 24 may identify the address following the string "owner" in the rights holder and other matters data of the Section A element data as the address of the most recent owner, and identify the name following the string representing that address as the name of the most recent owner.

[0072] In this example, in the process shown in S108, for example, it is checked whether there is another registration data set to which the owner group ID is already associated, where the combination of the owner's name and the owner's address is the same as the registration data to be grouped. Here, if the real estate associated with the registration data to be grouped is jointly owned real estate, for example, it is checked whether there is another registration data set to which the owner group ID is already associated, where the combination of the owner's name and the owner's address is the same for all owners as the registration data to be grouped.

[0073] In the example above, there are two owners, and the name and address of one owner are "Qgawa R Taro" and "A Prefecture E City F Town G24-1," while the name and address of the other owner are "Mita P Ko" and "A Prefecture B City C Town D125-3." It is checked whether there is another registration data set that already has an associated owner group ID. In this example, the number of owners is the same, and the combination of name and address matches for all owners. It is checked whether there is another registration data set that already has an associated owner group ID.

[0074] In this embodiment, the registration information acquisition unit 26 acquires, for example, one of several pieces of registration information, which is the registration information of interest. The registration information acquisition unit 26 acquires, for example, any one of several pieces of registration information data stored in the registration information storage unit 20 as the registration information data of interest. Hereinafter, the real estate associated with the registration information data of interest will be referred to as the real estate of interest.

[0075] In this embodiment, the inheritance-occurring real estate estimation unit 28 determines, for example, whether there is a focus registration application information that pertains to the real estate shown in the focus registration information and indicates that the purpose of registration is the transfer of ownership through inheritance. The inheritance-occurring real estate estimation unit 28 determines, for example, whether there is a focus registration application information data among the multiple registration application information data stored in the registration application information storage unit 22 that pertains to the focus real estate and indicates that the purpose of registration is the transfer of ownership through inheritance.

[0076] Then, if the inheritance-occurring real estate estimation unit 28 determines that there is a registration application information of interest, it estimates that real estate associated with registration information different from the registration information of interest, where one or more owners are common to the registration information of interest, is real estate where an inheritance has occurred or real estate where an inheritance is highly likely to occur. Hereinafter, the owner identified with respect to the registration information of interest will be referred to as the owner of interest.

[0077] Here, the inheritance property estimation unit 28 may estimate as inheritance property a property where there are multiple owners of interest, and all of those multiple owners are the owners of interest, and which is associated with registration information different from the registration information of interest.

[0078] For example, if the inheritance property estimation unit 28 determines that a registration application information of interest exists, it may identify one or more other registration information data from among the multiple registration information data stored in the registration information storage unit 20 whose associated owner group ID is the same as the registration information data of interest. Then, the real estate associated with each of the one or more other registration information data obtained in this way may be estimated as the inheritance property.

[0079] For example, let's assume that the registration information data shown in Figures 2A and 2B are the registration information data of interest. In this case, based on the registration information data of interest, the string "A Prefecture B City C Town D123-1", which is formed by combining the predetermined string "A Prefecture", the location data value "B City C Town D", and the land number data value "123-1", is identified as the land number of the property of interest that is associated with the registration information data of interest.

[0080] Then, from among the multiple registration application information data stored in the registration application information storage unit 22, the string formed by combining the values ​​of prefecture name data, city / ward / town / village name data, district name data, and land number / house number data is identified as "A Prefecture B City C Town D123-1", and the value of the use data is "land". Hereinafter, each of the one or more registration application information data identified in this way will be referred to as the registration application information data of interest.

[0081] Then, it is checked whether there is one or more of the target registration application information data where the value of the registration purpose data is "transfer of ownership and inheritance". If it is found, that target registration application information data corresponds to the target registration application information.

[0082] Furthermore, if it is determined that a registration application information of interest exists, as described above, one or more other registration information data that have the same associated owner group ID as the registration information data of interest may be identified from among the multiple registration information data stored in the registration information storage unit 20. Then, the real estate associated with each of the one or more other registration information data obtained in this way may be presumed to be the real estate for which inheritance has occurred.

[0083] As described above, according to this embodiment, by grouping registration information by owner and utilizing registration application information, it becomes possible to accurately estimate real estate that has been inherited or real estate that is highly likely to be inherited.

[0084] In the above example, the property of interest was land, but even if the property of interest is a building or a subdivided building, it is possible to estimate the property from which the inheritance occurred using the same method.

[0085] Furthermore, in this embodiment, as described above, it is not necessary to presume that real estate shown in other registration information that perfectly matches the combination of owner, address, and name identified in the registration information of interest is real estate that has been inherited.

[0086] For example, the inheritance property estimation unit 28 may estimate as inheritance property a property where, if there is one owner of interest, there are multiple identified owners, and any of those multiple owners is the owner of interest, and the property is associated with registration information different from the registration information of interest.

[0087] For example, suppose the first property is exclusively owned by Mr. A, and the second property is jointly owned by Mr. A and Mr. B. In this case, if the registration information data for the first property is the registration information data of interest, then Mr. A is the owner of interest. In this case, since Mr. A is included among the identified owners of the second property, it may be presumed that the second property is the property for which inheritance occurred.

[0088] Furthermore, for example, the inheritance property estimation unit 28 may estimate as inheritance property a property where, if there are multiple owners of interest, there is one identified owner, and that owner is one of the multiple owners of interest, and the property is associated with registration information different from the registration information of interest.

[0089] For example, suppose the first property is jointly owned by Mr. A and Mr. B, and the second property is exclusively owned by Mr. A. In this case, if the registration information data for the first property is the registration information data of interest, then Mr. A and Mr. B are the two owners of interest. In this case, since the owner identified for the second property is Mr. A, it may be presumed that the second property is the property subject to inheritance. Furthermore, in this case, it may be presumed with a 50% probability that the second property is the property subject to inheritance.

[0090] Furthermore, for example, the inheritance-related real estate estimation unit 28 may estimate as inheritance-related real estate if there are multiple owners of interest, and any of those multiple owners is one of the multiple owners of interest, and the real estate is associated with registration information different from the registration information of interest.

[0091] For example, suppose the first property is jointly owned by Mr. A and Mr. B, and the second property is jointly owned by Mr. A and Mr. C. In this case, if the registration information data for the first property is the registration information data of interest, then Mr. A and Mr. B are the two owners of interest. In this case, since Mr. A is included among the identified owners of the second property, it may be presumed that the second property is the property subject to inheritance. Furthermore, in this case, it may be presumed with a 50% probability that the second property is the property subject to inheritance.

[0092] Alternatively, the number of inherited properties may be estimated to match the number of parcel data entries included in the registration application information data, which is the registration application information of interest. Alternatively, the inherited properties may be estimated using the method for estimating properties corresponding to parcel information as described in Japanese Patent Publication No. 2017-228123.

[0093] In this embodiment, the association unit 30 associates, for example, the registration application information of interest with the registration information of the real estate related to the registration application information of interest, which is obtained after the date of receipt of the registration application information of interest.

[0094] For example, from among the multiple registration information data stored in the registration information storage unit 20, a registration information data containing Section A element data that includes the same date as the date indicated by the date of receipt data included in the registration application information data which is the registration application information of interest, and the same receipt number as the receipt number included in the registration application information data which is the registration application information of interest, may be identified. The association unit 30 may then associate the registration information data identified in this way with the registration application information data which is the registration application information of interest.

[0095] By doing so, it becomes possible to identify the heirs, the deceased, the date of death, etc., of the real estate that is the subject of the registration application related to the registration application information of interest.

[0096] However, the present invention is not limited to the embodiments described above.

[0097] Furthermore, the specific strings and numbers mentioned above, as well as the specific strings and numbers in the drawings, are examples only and are not limited to these strings and numbers. [Explanation of symbols]
