Description

The present invention relates to an electronic contract support system and an electronic contract support method for real estate such as used real estate.

2. Description of the Related Art In recent years, with the advancement of Internet technology and IT technology, various sales systems for goods using the Internet have been proposed in various industries. For the sale of single-family homes, newly built condominiums, and second-hand homes, systems have been proposed to reduce the burden on sales representatives, customers, and other parties concerned.

For example, when the owner of a house such as an apartment needs to move, it is necessary to compare various conditions to select a new house to purchase. In other words, if you sell a property you currently own and use the proceeds to purchase a new property, the selling price of the property you own will depend on the selection of the new property. become an important factor.

In this regard, as shown in Patent Document 1, there has been proposed a housing change support system that simply provides purchase conditions for a property to be relocated to, taking into account the selling price of the property currently owned.
A user of this support system can easily obtain the purchase conditions of a property to be relocated to, taking into account the selling price of the property that the user currently owns.

Japanese Patent No. 6535726

By the way, construction contracts for detached houses, sales contracts for new condominiums, detached houses, used houses, investment/business buildings, etc., loan contracts for repaying loans for real estate transactions such as buildings and land, etc. In lease contracts for rental housing, rental stores, offices, tenants, parking lots, etc., and management consignment contracts for housing and parking lots (hereinafter referred to as real estate contracts), especially construction contracts for detached houses, new condominiums, In many cases, a financial plan is prepared in advance when signing a loan contract for repaying a loan for a real estate transaction such as a building or land transaction, as well as a sales contract for a built house or a second-hand house. Since the financial plan contains items that are difficult for some applicants to fill out properly, a sales representative is appointed for each applicant, and this sales representative is assigned to the applicant. After asking about their income situation, they often create a financial plan.
In addition, in the case of construction contracts for detached houses, sales contracts for newly built condominiums, detached houses, and second-hand houses, and loan contracts for repaying loans for real estate transactions such as buildings and land, the contents of the contract A memorandum is required for confirmation of the contract, etc., but the memorandum may require multiple types of memorandums with different contents depending on the content of the contract.

For this reason, for example, if a person other than the sales person who created the financial plan is in charge, such as when the person in charge of the contract is in charge of creating the memorandum, the applicant Even if the information obtained from the However, the burden on the applicants was heavy because they had to hear the necessary information again from the applicants.
In addition, if the person in charge changes during the period from the application of the real estate contract to the conclusion of the contract, there will be problems in progress management, such as omissions in sending documents to applicants and omissions in filling in documents. It was a heavy burden on the person in charge to prevent the problem.
Therefore, there is a demand for a system that reduces the burden on the person in charge and the applicant even if the person in charge changes during the period from the application of the real estate contract to the conclusion of the contract.

In order to solve the above-mentioned problems, the inventors of the present invention provide support for reducing the burden on the applicant and the person in charge of the applicant from the application of the real estate contract to the conclusion of the contract. A patent application has been filed for an invention related to the system (Japanese Patent Application No. 2020-85700).
By the way, especially in the case of a sales contract for second-hand real estate, it is common practice to conclude a real estate contract between a seller and a buyer through the person in charge of the seller's intermediary company and the person in charge of the buyer's intermediary company. In such a case, since the above four parties (seller, buyer, seller's intermediary company representative, buyer's intermediary company representative) are involved in the work of concluding a contract, the above-mentioned unique e-commerce transaction problem was found to occur.

In other words, in second-hand real estate brokerage business, complicated transaction business is carried out appropriately and smoothly by having each real estate brokerage intervene between the seller and the buyer. If this is done in the form of electronic commerce using an electronic contract system, the name and e-mail address of the contracting party will be confirmed due to the need for personal authentication in the process of creating the contract and the agreement conclusion certificate regarding the contract. things are done. As a result, the e-mail address used by the parties to the contract becomes apparent to the parties to the contract.

In that case, the person in charge of the intermediary company on the side of the seller or the buyer may negotiate a sales contract with the other party without going through the intermediary company of the other party. A situation may arise in which a large volume of sales mail is sent directly to the other party without going through the other party's intermediary company.
If such a situation occurs, the other intermediary company will lose the opportunity to obtain a proper transaction fee, or the other intermediary company will be unfairly deprived of the results of its own sales efforts by the other intermediary company. It can only develop to the point where it will be lost.

Such problems are unique to the electronic commerce of used real estate involving four parties: the seller, the buyer party, and their respective brokerage firms. Electronic commerce of used real estate can only be realized by solving such a unique problem, and the present invention provides means for solving this problem.

The real estate contract support system of the present invention has been devised to solve the above problems, and its configuration is such that a real estate contract between a seller and a buyer is executed through a seller's intermediary and a buyer's intermediary. In the system, as an e-mail address for personal identification of the seller and the buyer of the real estate, an electronic contract e-mail address different from the one usually used by the seller or the buyer can be set as the e-mail address used in the real estate contract system. Characterized by

In addition, it is preferable that the e-mail address for the electronic contract of the seller or the buyer is kept secret from each contract counterparty and the person in charge of intermediary for the contract counterparty.
In the real estate contract system, an e-mail sent from either the seller or the buyer to the electronic contract e-mail address of the other party is not forwarded to the e-mail address normally used by the other contracting party, but the e-mail from the electronic signature service It is preferably configured to forward only email addressed to the contracted email address to the email address normally used by the contracted parties.

According to the present invention, in a real estate contract support system for reducing the burden on parties concerned, such as an applicant and a person in charge of a brokerage company in charge of the applicant, from application for a second-hand real estate contract to conclusion of the contract, the seller Alternatively, a system can be provided in which the e-mail address of one contracting party of the buyer is concealed from the other contracting party and its intermediary company to conclude a contract.

Further, in the following explanation, the intermediary company that uses this support system is called the intermediary company that uses it, and the intermediary company that concludes the real estate contract is called the other intermediary company. In ordinary real estate transactions, it is common for the seller's intermediary company to be the intermediary company to be used. can do.

(contract e-mail system)
First, the method of handling e-mails adopted in this support system will be described.
In this support system, the e-mail address for the electronic contract of the seller and the buyer shall be set for each property handled, and the e-mail address for the electronic contract shall be set by the seller, the buyer, and the intermediary company of each of the seller and the buyer at the start of the transaction. get the approval of After that, the work of concluding an electronic contract using an electronic signature service is started.

The consistency of the email addresses normally used by the seller and the buyer and the newly set e-mail address for electronic contracts shall be ensured within this support system at each stage of the generation, management and storage of e-mail addresses for electronic contracts.
As a result, even if an e-mail is sent to the seller's or buyer's electronic contract e-mail address, in the case of an e-mail from the electronic signature service, the e-mail will be automatically forwarded to the e-mail address normally used by the seller or buyer. , can work to conclude an electronic contract using an electronic signature service. However, even if an e-mail is sent to the seller's or the buyer's electronic contract e-mail address from a service other than the electronic signature service, the e-mail will not be forwarded to the seller's or the buyer's normally used e-mail address. It is not possible to exchange e-mails directly without going through an electronic signature service.
This makes it possible to avoid various troubles in concluding a contract as described above.

(Confirmation of identity of e-mail address for electronic contract)
In a general real estate transaction, the identity of the parties to the contract is secured by the intermediary company confirming the driver's license, deed of title, certificate of seal impression, and the like. At that time, we also verify the identity of the contracting party's email address. However, in addition to the e-mail addresses normally used by contract parties, this support system also checks and manages electronic contract e-mail addresses temporarily set for individual electronic contracts.

Specifically, the seller intermediary company notifies the seller of the registration URL, and the seller obtains the ID through the registration URL. Afterwards, the seller registers a password and confirms the email address he normally uses. This information is registered and confirmed. The buyer's intermediary company (other intermediary company) makes a similar request to the buyer.
Then, the e-mail addresses normally used by the seller and the buyer are registered in the electronic contract e-mail address D/B of this support system, and the electronic contract e-mail addresses of the seller and the buyer are created in the electronic contract e-mail address generation part. Then, the e-mail addresses for the electronic contract are separately notified to the seller and the buyer, and the electronic contract creation work for the real estate transaction is started using these e-mail addresses.
The electronic contract email address generated by this support system is a random combination of alphabets, numbers, and symbols, ensuring a high level of confidentiality.

(Operation of this support system)
Next, the operation of this support system will be described with reference to FIG.
First, as a preliminary preparation, the system administrator of the operating company of this support system uses the system administrator terminal 30 to register a user with personnel management authority to a real estate brokerage company that wishes to use the system. In the following, a series of procedures will be described in the case where a seller intermediary company uses this support system to mediate a seller and conclude a sales contract for second-hand real estate of the seller. Through this advance preparation, the seller's intermediary company is registered as a use intermediary company.

First, the person in charge is set and the property is registered (S1).
The personnel manager of the seller intermediary company, which is the intermediary company using this support system, uses the personnel manager terminal 40 to register sales representatives and contract approvers. After that, the registered salesperson uses the salesperson terminal 50 to input information related to the property such as the transaction form and transaction price to register the property.
In the registration of the contract approver, it is possible to set a plurality of approval routes that require approval procedures at the seller's intermediary company corresponding to the real estate business.

Next, the partner brokerage company/contractor registration (S2) is performed.
A salesperson of the seller's intermediary company uses the salesperson's terminal 50 to register information on the seller, the buyer, the person in charge of the buyer's intermediary company, and other parties involved in the contract if necessary. Also, the salesperson requests the person in charge of the buyer brokerage company to register the password. The person in charge of the buyer's brokerage company logs in to this support system, performs two-factor authentication, and then registers a password.

Next, an e-mail address for electronic contract is issued (S3).
A salesperson asks the seller in charge to register a commonly used email address and password. An e-mail address for an electronic contract will be issued when the seller registers the e-mail address and password that the seller normally uses and performs two-factor authentication. After that, the salesperson requests the person in charge of the buyer brokerage company to register the e-mail address normally used by the buyer. The person in charge of the buyer brokerage company asks the buyer to register the e-mail address that is usually used, and the buyer registers the e-mail address and password that he or she usually uses, and when two-factor authentication is performed, the e-mail address for electronic contracts is issued. .

Next, the contract documents are uploaded (S4).
A sales representative of the seller's intermediary company uploads the contract to be electronically contracted to the delivery document storage section 101E of the main server device 10 of this support system. Select the seller and buyer to be contracted for the contract information. The sending document storage unit 101E is also utilized for storing contract-related documents.

Next, in-house approval is performed (S5).
The sales representative of the seller's intermediary company requests approval of the contract information from the contract approver set in S1. Then, each approver confirms the contract information on the system using the contract approver terminal 60, and approves it if there is no problem with the content. If there is a problem, the contract approver's terminal 60 is used to return the contract. In the case of remand, the sales person uploads the contract documents (S4) and redoes the contract conclusion work.

Next, an electronic contract is made based on the internally approved documents (S6).
The salesperson who has performed the two-factor authentication transmits the document approved by the company to the sending document storage section 201E of the external server device. Contract document confirmation emails are sent to the electronic contract email addresses of the seller and the buyer from the sending document storage unit 201E that has received the transmission. After that, the following steps a) to c) are repeated.
a) The mail server determines whether or not the sender of the contract document confirmation mail delivered to the electronic contract mail addresses of the seller and the buyer is from the external server device 20 .
b) As a result of the determination, if the contract document confirmation mail is from the external server device 20, the contract document confirmation mail is forwarded to the seller's normally used mail address. If the mail is not from the external server device 20, the contract document confirmation mail is discarded.
c) The seller performs two-factor authentication from the received notification, opens the URL, and confirms the contract information. If there is no problem with the contract documents, the contract is approved. Then, when the seller's approval is completed, a contract document confirmation mail is sent from the external server device 20 to the electronic contract mail address of the buyer. Similarly, approval of the buyer's contract is made.
These steps are repeated until the contract is finally completed.

Finally, electronic contract completion document data is received (S7).
After the approval of all contractors is completed, the concluded contract data is generated by the external server device. When this support system detects the conclusion of a contract and fetches concluded contract document data from an external server device, the contract document data is stored in the file server as final data.
From the external server device, the concluded contract document data is sent to all e-mail addresses related to the contract. This completes the work in the contract support system.

(Effect obtained by this support system)
Advantageous effects obtained by using this support system will be explained.
This support system is a system that supports the execution of sales contracts in the form of electronic commerce, which are concluded with the involvement of the seller, the buyer, the seller's intermediary company, and the buyer's intermediary company.
General electronic commerce is conducted between two parties, a seller and a buyer. However, in such electronic commerce, even if the e-mail addresses of the seller and the buyer were known to the parties, it would not pose a particular problem. The present invention provides a clear solution to dealing with the e-mail addresses of buyers and sellers, which is particularly problematic in electronic commerce involving three or four parties involving sellers, buyers, and intermediaries. By applying the solution adopted in the present invention, the various problems described above can be obviated.

In addition, users of this support system can enjoy the following various advantages expected in general electronic commerce. In other words, when a seller applies to a seller's intermediary company or a buyer to a person in charge of a buyer's intermediary company to buy and sell second-hand real estate, this support system is concluded between the seller, the buyer, the seller's intermediary company, and the buyer's intermediary company. can assist in the conclusion of sales contracts.

Furthermore, this support system has personal data of the potential contract person in the contract status D/B 201C of the storage unit 201 of the external server device 20, and prepares necessary documents for each potential contract person based on the personal data of each potential contract person. It has a contract management unit 202 that grasps the description status. As a result, even if the person in charge changes during the period from the application of the real estate contract to the establishment of the contract, it is possible to prevent troubles such as omission of sending documents to the applicant. Therefore, the burden on the person in charge of progress management can be reduced.
