When an heir lives in Hong Kong or Singapore: how is the signature on the estate division agreement certified?

In short: the estate division agreement is a procedure whose parties are the co-heirs (Article 907, paragraph 1 of the Civil Code), and its effect goes back to the time the inheritance opened (Article 909 of the Civil Code). When an heir lives in Hong Kong or Singapore, that person often has no Japanese residence record and cannot provide a seal certificate. A Japanese-national heir typically uses, instead of a seal certificate, signature certification at a Japanese diplomatic mission (the Consulate-General of Japan in Hong Kong or the Embassy of Japan in Singapore) and a certificate of residence abroad; a foreign-national heir uses signature certification by a local notary (Notary Public) or a sworn statement. Which form is usable depends on the requirements of the destination (the Legal Affairs Bureau or the financial institution). This article is general information organising the thinking on required documents, choosing the certification, exchanging the agreement, the documents added for inheritance registration and account closure, and referral in a dispute; it does not judge the acceptance of any individual document.

What does an heir without a Japanese residence record submit instead of a seal certificate?

A domestic estate division agreement is customarily sealed by all heirs with their registered seals and accompanied by seal certificates. But an heir who lives abroad and has left the Japanese resident register cannot register a seal and cannot obtain a seal certificate. So a document that officially certifies the address and the signature is used instead.

Category of heir	Document replacing the seal certificate	Issuer
Japanese national, living abroad	Signature certification, certificate of residence abroad	Japanese diplomatic mission (embassy / consulate-general)
Foreign national	Signature certification by a notary (Notary Public); a sworn statement (affidavit / statutory declaration)	A local notary, etc.

The certificate of residence abroad is a document proving the address (in place of a residence record), and the signature certification proves that the signature is the person's own. Within the scope of administrative-scrivener work, Yotsuba Administrative Scrivener Office supports preparing the estate division agreement and other inheritance documents and organising the certifications required per destination. The acceptance of any individual document is a matter for the destination — the Legal Affairs Bureau or the financial institution.

In Hong Kong and Singapore, is signature certification done at the mission or by a local notary?

Hong Kong and Singapore are both based on common law, and certification by a notary (Notary Public) and the culture of sworn statements are established there. The choice divides by the heir's nationality and the destination.

• Japanese-national heir: you can obtain signature certification at the Consulate-General of Japan in Hong Kong or the Embassy of Japan in Singapore. There is a form where you sign before a consular officer and the document and the certificate are bound together (Form 1), and a form where the certificate is issued on its own (Form 2). Japanese inheritance procedures often require Form 1, bound with the agreement. You also obtain a certificate of residence abroad.
• Foreign-national heir: because the mission's signature certification is for Japanese nationals, you use signature certification by a local notary (Notary Public) or a sworn statement. Hong Kong and Singapore have this system.

Which to use is most reliably arranged after confirming, in advance, the form required by the destination (the Legal Affairs Bureau for inheritance registration, each financial institution for account closure).

How do you exchange the estate division agreement with an English-speaking heir (translation, mailing)?

Exchanging the agreement with an overseas heir calls for care over comprehension and the time for the round trip.

• Attaching a translation: the agreement is drawn up in Japanese, and a reference translation into English or another language is attached so the heir can understand it. It is customary to attach a Japanese translation to certificates and foreign-language attachments when submitting them to the destination.
• The signing and certification steps: the completed agreement is mailed to the overseas heir, signed and certified at the mission or by a local notary, and returned. Because the round trip takes days, you guide the heir on where to sign and where to place the binding seals beforehand.
• Time difference and formats: line up the points often queried by the destination — the way the name is written (matching the alphabet and the kanji), the address, the date format.

Where there are several overseas heirs, each person's document may be prepared separately. The order and the form of the exchange are designed to match the destination's requirements.

What extra documents are required for inheritance registration and account closure?

Even with signature certification and a certificate of residence abroad in hand, extra documents are needed per type of procedure.

Procedure	Documents / points likely to be added	In charge
Inheritance registration (name change of real estate)	Signature certification, certificate of residence abroad, the decedent's family register, etc., a certificate of registered matters for the property. The form follows the Order and the Regulation for Real Property Registration	A judicial scrivener
Closing / withdrawing a deposit	The financial institution's prescribed form, signature certification, a document showing the heirs' relationships. Required documents differ by institution	Each financial institution
Inheritance tax filing	Valuation of overseas and domestic assets, whether a tax agent is needed	A tax accountant

The agency application for inheritance registration is the work of a judicial scrivener; an administrative scrivener does not make registration applications. Filing and computing inheritance tax is the field of a tax accountant. Our office handles preparing the estate division agreement and other inheritance documents. For the whole flow of inheritance registration, see How do you proceed with inheritance registration?; for how to draw up the estate division agreement, see Can you draw up an estate division agreement yourself?.

Who to consult when there may be a dispute (referral to a lawyer)?

Estate division does not move forward if the heirs cannot agree. A matter with a dispute — a fight over the content of the division, or where the statutory reserved portion becomes an issue — is the field of a lawyer. Our office handles the part of putting into writing content on which agreement has been reached, and does not act as agent in disputed negotiation, mediation or litigation.

The roles by field are as follows.

• Preparing the estate division agreement and other inheritance documents, and organising the required certifications → Yotsuba Administrative Scrivener Office (administrative scrivener)
• The application for inheritance registration (name change of real estate) → a judicial scrivener
• Filing and computing inheritance tax → a tax accountant
• Disputes such as failed negotiations, the reserved portion, or the scope of the estate → a lawyer
• Sale and appraisal of inherited real estate → Yotsuba Real Estate Co., Ltd. (licensed real estate broker)

Yotsuba Administrative Scrivener Office and Yotsuba Real Estate Co., Ltd. are separate businesses. Each field, including the judicial scrivener, the tax accountant and the lawyer, is on the premise that you contract separately with each qualified professional as an independent business, and our office receives no referral fee.

FAQ

Q. I am a Japanese national living in Hong Kong. Can I take part in the estate division without a seal certificate?
A. You can. Instead of a seal certificate, you obtain signature certification at the Consulate-General of Japan in Hong Kong, and you show your address with a certificate of residence abroad. Japanese inheritance procedures often require the form bound with the agreement (Form 1), so confirm the destination's form before arranging the signing.

Q. There is a foreign-national heir living in Singapore. Can they get signature certification?
A. The mission's signature certification is for Japanese nationals. A foreign national typically uses signature certification by a local notary (Notary Public) or a sworn statement. Which form is accepted depends on the requirements of the Legal Affairs Bureau (for inheritance registration) or the financial institution (for account closure), so we confirm in advance.

Q. Can the agreement be made in English?
A. An estate division agreement submitted to a Japanese destination is drawn up in Japanese, and a reference translation into English or another language is customarily attached for the overseas heir's understanding. A Japanese translation is attached to foreign-language certificates and attachments. We also line up the correspondence between the alphabet and the kanji for the name.

Q. The heirs cannot agree on how to divide. Can I ask an administrative scrivener to negotiate?
A. Agency in disputed negotiation, mediation or litigation is the work of a lawyer; an administrative scrivener does not do it. Our office handles putting into writing content already agreed. If there is a dispute, consult a lawyer; for inheritance registration, a judicial scrivener; for inheritance tax, a tax accountant — each as an independent business under a separate contract. Our office receives no referral fee.
