Transferring Mortgage Rights (抵当権移転) in Japan: What You Need to Know

In the dynamic landscape of finance and commerce, loans are often bought and sold, and corporate structures evolve through mergers and reorganizations. When these transactions involve debts secured by Japanese real estate mortgages (抵当権 - teitōken), the mortgage rights themselves must also be effectively transferred. Understanding the mechanisms and legal requirements for transferring mortgage rights in Japan is crucial for assignees to secure their position and for all parties to ensure clarity and enforceability. This article explores how Japanese mortgages are typically transferred, the pivotal role of registration, and various scenarios encountered in practice.

The Guiding Principle: A Mortgage Follows the Claim (随伴性 - Zuihansei)

The cornerstone of mortgage transfer in Japan is the principle of accessory nature (随伴性 - zuihansei, also often linked with 付従性 - fujūsei). An ordinary mortgage is intrinsically linked to the underlying debt or obligation it secures. As a general rule, when the secured claim (e.g., a loan receivable) is transferred from one creditor to another, the mortgage securing that claim automatically follows and transfers with it. The mortgage is an accessory to the claim, not an independent asset that can be freely traded separately from the debt it supports.

While this accessory transfer is the default, parties can, in some specific and less common circumstances, agree otherwise. For example, if a claim is assigned with an explicit agreement that the associated mortgage will not transfer, the mortgage might be extinguished. However, the far more common scenario, particularly in loan portfolio sales or internal reorganizations, is that the mortgage travels with the claim.

It's important to distinguish this type of transfer—where the mortgage follows the assigned claim—from what is known as "disposition of the mortgage right itself" (抵当権の処分 - teitōken no shobun). The latter involves dealing with the mortgage right in a more isolated manner, such as creating a sub-mortgage (転抵当 - ten-teitō) on an existing mortgage or transferring only the priority of a mortgage to another creditor. This article focuses on the more prevalent situation: the transfer of the mortgage as a consequence of the transfer of the underlying secured obligation.

Types of Mortgage Transfer

Mortgage transfers in Japan can broadly be categorized into two main types: comprehensive succession and specific transfer.

1. Comprehensive Succession (包括承継 - Hōkatsu Shōkei)

This occurs when all or a significant portion of the rights and obligations of a mortgagee are succeeded to by another entity or individual due to a specific legal event. Registration for such transfers is typically a sole application by the successor.

• Inheritance (相続 - Sōzoku): If an individual mortgagee passes away, their rights to the secured claim and the associated mortgage are comprehensively succeeded by their legal heir(s). The mortgage then becomes an asset of the heir(s). The registration is effected by a sole application by the heir(s), supported by documents proving the inheritance.
• Merger of Corporations (合併 - Gappei): When a corporate mortgagee merges with another company (either through absorption by another company or by consolidating to form a new company), the surviving or newly created company comprehensively succeeds to the assets, rights (including mortgage rights and secured claims), and obligations of the merged company. The mortgage transfer is registered via a sole application by the successor company, evidenced by its commercial registration showing the merger.
• Company Split (会社分割 - Kaisha Bunkatsu): This is also a form of comprehensive succession, but its scope is limited to the specific business undertaking that is being split off from one company (the splitting company) and transferred to another (the succeeding company or a newly established company). If a secured claim and its attendant mortgage are part of the assets and liabilities designated for transfer within the approved company split plan or agreement, they pass to the succeeding company.
  Unlike inheritance or merger, the registration of a mortgage transfer resulting from a company split requires a joint application by the splitting company (as the registration obligor, losing the right) and the succeeding company (as the registration rights-holder, gaining the right). The process involves submitting the company split plan/agreement and relevant corporate registrations as proof. The specific determination of which claims and mortgages are transferred can be complex and depends on the precise wording of the split documentation. If the splitting company's registered name or head office has changed prior to the split, these changes must first be updated on the mortgage registration before the transfer due to the split can be registered.

2. Specific Transfer (特定承継 - Tokutei Shōkei)

This involves the transfer of a specific mortgage right, usually as a consequence of the transfer of the specific claim it secures. This is typically a contractual arrangement between the existing mortgagee and a new creditor.

• Assignment of the Secured Claim (債権譲渡 - Saiken Jōto): This is the most common method of specific transfer. When a creditor (mortgagee) sells or assigns a loan (the secured claim) to a third party (the assignee), the mortgage securing that loan automatically transfers to the assignee due to the principle of zuihansei. The mortgage follows the debt.
• Subrogation by Payment (代位弁済 - Dai'i Bensai): If a third party, such as a guarantor or a junior mortgagee, pays off the secured debt owed to the primary mortgagee, that third party may become legally subrogated to the rights of the original mortgagee. This subrogation can include the transfer of the mortgage right to the paying party.
• Subrogation under Civil Code Article 392, Paragraph 2 (民法392条2項の代位): This refers to specific subrogation rights that arise in the context of joint mortgages. If one of several jointly mortgaged properties is sold and the proceeds are used to satisfy the joint mortgagee, a junior mortgagee on that sold property may, under certain conditions, subrogate to the senior joint mortgagee's rights against the other unsold properties. This effectively transfers a portion of the senior mortgage benefit to the junior mortgagee.
• Court Orders (e.g., Transfer Order - 転付命令 - Tenpu Meirei): In some enforcement scenarios, if a creditor of the mortgagee successfully attaches the mortgage-backed claim held by their debtor (the mortgagee), a court can issue a transfer order (tenpu meirei). This order effectively transfers the secured claim, and by accessory nature the mortgage, from the original mortgagee to their attaching creditor. The registration of this transfer is then typically commissioned by the court.

Registration of Mortgage Transfer (抵当権移転登記 - Teitōken Iten Tōki)

While the mortgage may legally transfer between parties upon the assignment of the claim or by operation of law (like inheritance), registration of this transfer is essential to perfect the new mortgagee's rights against third parties. Such third parties could include the original debtor (mortgagor), other creditors of the original mortgagee, subsequent assignees of the same mortgage from the original mortgagee, or a bankruptcy trustee of the original mortgagee. An unregistered mortgage transfer, while generally valid between the assignor and assignee, offers the assignee no reliable protection against these competing third-party claims.

Registration Procedure (Focusing on Assignment of Claim):

• Joint Application (不動産登記法第60条 - Article 60 of the Real Property Registration Act): The transfer of a mortgage due to claim assignment is registered through a joint application. The assignee (the new creditor/mortgagee) acts as the "registration rights-holder" (登記権利者 - tōki kenrisha), and the assignor (the original creditor/mortgagee) acts as the "registration obligor" (登記義務者 - tōki gimussha). The property owner (mortgagor) is generally not a party to this mortgage transfer registration application, nor is their consent typically required for the transfer itself between the old and new creditor.
• Cause of Registration (登記原因 - Tōki Gen'in): For a transfer due to claim assignment, the cause is typically stated as "Assignment of Claim" (債権譲渡 - saiken jōto), along with the effective date of the assignment.
• Registered Details: The registration will be made as an ancillary registration (付記登記 - fuki tōki) to the original mortgage registration. It will record the name and address of the new mortgagee (the assignee).
• Attached Information (添付情報 - Tenpu Jōhō):
  • Proof of the Cause of Registration (登記原因証明情報 - tōki gen'in shōmei jōhō): This is usually the original claim assignment agreement between the assignor and assignee.
  • Assignor's Title Identification Information: The original mortgagee (assignor) must provide their Title Identification Information (登記識別情報 - tōki shikibetsu jōhō) or, for older mortgages, their Certificate of Registered Matters (登記済証 - tōkizumishō) pertaining to the mortgage being transferred. This authenticates their authority to transfer the registered mortgage right.
  • Corporate Documents: If the assignor or assignee are corporations, their corporate registration details (often verified via their corporate number) and certificates of a representative's authority may be needed.
  • Power of Attorney (委任状 - ininjō): If a judicial scrivener is handling the application.
  • Proof of Perfection of Claim Assignment against Debtor (Not for Mortgage Registration, but Crucial): It is vital to distinguish between perfecting the mortgage transfer registration (which makes the assignee the recognized mortgagee against third parties concerning the property) and perfecting the underlying claim assignment itself against the debtor and other claimants to the debt. For the assignee to be able to demand payment from the debtor, and for the assignment of the claim to be effective against other assignees of the same claim or attaching creditors of the assignor, the assignment must generally be perfected under Article 467 of the Civil Code. This usually requires either (a) notice of the assignment from the assignor to the debtor, or (b) the debtor's consent to the assignment, in either case with a "certified date" (確定日付 - kakutei hizuke) obtained from a notary public or through specific types of mail. While proof of this Article 467 perfection is generally not required as an attached document for the mortgage transfer registration itself, failing to perfect the claim assignment can render the mortgage transfer practically meaningless if the assignee cannot enforce the underlying debt. An old Supreme Court judgment (Taishō 10.2.9) indicated that an unperfected claim assignment could undermine even a registered mortgage transfer against third parties with superior rights to the claim itself.
• Registration and License Tax (登録免許税 - Tōroku Menkyo Zei):
  • For specific transfers like assignment of claim, the tax is typically 0.2% of the current outstanding amount of the secured claim being transferred (with amounts under ¥1,000 rounded up, and a minimum tax often applying).
  • For comprehensive successions like mergers or certain qualifying company splits, a lower rate, often 0.1% of the registered mortgage amount, may apply.

Specific Scenarios in Mortgage Transfer by Assignment:

• Full Assignment of Claim: If the entire secured claim is assigned, the entire mortgage right transfers to the assignee. The registration will be "Transfer of Mortgage No. X" (X番抵当権移転).
• Partial Assignment of Claim (債権一部譲渡 - Saiken Ichibu Jōto): If only a portion of the total secured claim is assigned, the mortgage right becomes quasi-co-owned (準共有 - jun-kyōyū) by the assignor and the assignee, usually in proportion to their respective shares of the remaining claim. The registration will reflect this as a "Partial Transfer of Mortgage No. X" (X番抵当権一部移転), and importantly, the "Amount Transferred" (譲渡額 - jōto gaku, meaning the principal amount of the claim portion being transferred) must be specified as a registered particular.
• Assignment of a Share in an Already Co-owned Mortgage (債権持分譲渡 - Saiken Mochibun Jōto): If a mortgage is already co-owned (e.g., by two banks), and one co-owner assigns their share of the underlying secured claim, their corresponding share in the co-owned mortgage right will transfer to the assignee. The registration would be for "Transfer of Co-owner [Name]'s Share of Mortgage No. X."
• Assignment of Claim Against One of Several Joint and Several Debtors: If a single mortgage secures a claim against multiple joint and several debtors, and the mortgagee assigns only the portion of the claim attributable to or enforceable against one specific debtor, a partial transfer of the mortgage can be registered. The cause of registration would specify "Assignment of Claim (claim pertaining to joint and several debtor D)". The mortgage then becomes co-owned by the assignor and assignee.
• Successive Assignments: If an assignee who received a partial transfer of a mortgage further assigns their acquired portion, the new transfer is registered as an ancillary registration to the previous ancillary transfer registration (付記登記の付記登記 - fuki tōki no fuki tōki). If the assignee had received the entire mortgage and then assigns the entire mortgage again, the second transfer would be a new primary ancillary registration to the original main mortgage registration.

Conclusion

The transfer of mortgage rights in Japan is predominantly governed by the principle that the mortgage follows the secured claim. Whether through comprehensive succession events like inheritance or corporate mergers/splits, or through specific transfers like the assignment of a loan, the shift in the underlying creditor position generally results in a corresponding shift in the mortgage right.

For the new mortgagee, registering this transfer (抵当権移転登記 - teitōken iten tōki) is not merely an administrative formality; it is a critical step to perfect their rights against third parties and ensure their ability to enforce the mortgage. Different scenarios, such as full or partial assignments, or transfers involving corporate reorganizations, come with specific documentation and registration requirements, as well as distinct tax implications. Furthermore, while the mortgage transfer registration perfects rights in the collateral, ensuring the underlying assignment of the claim itself is properly perfected against the debtor is an equally vital, though separate, legal step. Navigating these processes effectively usually requires the expertise of Japanese legal professionals and judicial scriveners.
