Renouncing a Taiwanese Parent's Debts From Japan: The Three-Month Deadline

Under Taiwan's Civil Code, an heir who wants to renounce an inheritance must do so in writing to the court within three months of learning that he or she can inherit (Article 1174). Living in Japan, or holding a Japanese passport, does not change that period, and nothing in the Civil Code adds time for getting papers authenticated at Taiwan's office in Japan.

Suppose your father, a Taiwanese national, lived in Taichung and died leaving credit card debt, a guarantee he signed for a friend's business, and unpaid tax. You are his only child. You moved to Tokyo years ago for work and have since naturalized in Japan. There is little to inherit, and you do not want the debts.

Taiwan law governs, whatever passport you hold

Taiwan's choice-of-law statute applies the law of the deceased's nationality at the time of death (Article 58 of the Act Governing the Choice of Law in Civil Matters Involving Foreign Elements). The test is your father's nationality, not yours and not where you live. Japan's Act on General Rules for Application of Laws starts from the same place: Article 36 says inheritance is governed by the national law of the decedent.

That affects where you file. Under Japan's Civil Code, a renunciation is a statement made to a Japanese family court (Article 938). Taiwan's Article 1174 calls for a written statement to the court, and Article 127 of Taiwan's Family Act gives exclusive jurisdiction over renunciation matters to the court for the place where the deceased was domiciled when the succession opened. It is safer not to assume that a filing in Japan counts as a renunciation under Taiwan law. For assets in Japan and for the Japanese procedure, ask a Japanese professional.

Liability is capped at the estate, so why renounce?

Under Article 1148, paragraph 2, an heir is liable for the deceased's debts only up to the estate the heir receives. Gifts the heir received from the deceased in the two years before death are treated as part of that estate (Article 1148-1).

Staying an heir still comes with rules. Article 1156 has an heir file an inventory of the estate (遺產清冊) with the court within three months of learning of the inheritance, and the court may extend that period on the heir's application if it finds an extension necessary. An heir who files no inventory must still pay all creditors out of the estate in proportion to their claims (Article 1162-1). An heir who breaks that rule becomes liable beyond the estate for whatever a creditor should have received but did not. The only exception is for heirs who lack full legal capacity (Article 1162-2).

If there is nothing worth inheriting, and you would rather not trace Taiwan creditors and make proportional payments from Japan, renunciation is the cleaner route. It takes effect retroactively from the opening of the succession (Article 1175).

When do the three months start?

The Taipei District Court, in ruling 112 Si-Ji-Zi No. 3207 (112年度司繼字第3207號) of January 30, 2024, read "learning that one can inherit" as the time the heir knows that the deceased has died and that he or she has become an heir under Article 1138. A child is a first-rank heir, so the period normally starts on the day the child learns of the parent's death.

The New Taipei District Court went further in ruling 114 Jia-Sheng-Kang-Zi No. 120 (114年度家聲抗字第120號) of December 29, 2025. The heir does not need to know whether there is any estate to inherit, the court said, and not knowing or misunderstanding the law makes no difference. Waiting until you have a full picture of the debts can cost you the deadline.

The written statement must give the person renouncing, the deceased's name and last domicile, the date, time and place of death, when the heir learned of the succession, and the names, sex, birth dates and addresses of any other heirs (Family Act, Article 132). If the renunciation is lawful, the court records it for reference (備查), notifies the renouncing heir and the other heirs it knows of, and publishes a notice. If it is not, the court dismisses it by ruling.

Authentication in Japan does not stop the clock

You do not have to fly to Taiwan. Point 54 of the Supplementary Provisions on Inheritance Registration (繼承登記法令補充規定) covers an heir living abroad who cannot return to file in person. That heir may sign the written renunciation addressed to the court, have it authenticated (驗證) by a Taiwan overseas mission, and mail it to an agent in Taiwan, who files it.

In Japan, the mission is the Taipei Economic and Cultural Representative Office in Japan (台北駐日經濟文化代表處) in Tokyo, and Taiwan also has offices in Yokohama, Osaka, Fukuoka, Naha and Sapporo (office list). As a rule, you apply to the office responsible for the place where the document is made (Article 10 of the document authentication act).

Three district-court rulings show that this route does not buy time.

In the New Taipei case, the heirs lived in the United States. They argued that the nearest Taiwan office was far away and that local notaries had questioned the forms, so authentication took a long time. The court held that Point 54 only makes filing easier for heirs who cannot come to court in person. It sets no special rule on the period, so Article 1174 still applies. The court dismissed their appeal.

In the Taipei 3207 case, the heirs explained that they had to obtain a death certificate abroad and have it certified at the local Taiwan office. The court called the three months a preclusive period (除斥期間). The heirs had learned of the death on the day it happened and filed more than eleven months later, and the court dismissed the application. In ruling 115 Si-Ji-Zi No. 236 (115年度司繼字第236號) of March 11, 2026, the same court dismissed an application that came with a mission-authenticated renunciation statement and power of attorney. The court had received it more than three months after the "date of learning" written on the statement itself.

In all three cases, the court measured the period by the date stamped on the application when the court received it.

Working back from the court's receipt date

Start by fixing the date. In the 236 ruling, an heir who learned of the death on September 17 had to file by December 17.

Next, choose the agent in Taiwan who will file, and have two documents authenticated at the office for your area: the renunciation statement (拋棄繼承權聲明書) and a power of attorney (授權書) for the agent. The Yokohama branch's guidance says the person signing must in principle come to the counter in person and that review usually takes three to five working days (checked October 5, 2026). A sample statement published on the mission website has a box for the "date of becoming aware of the right to inheritance". In the 236 case, the court took the date written in that box as the start of the period.

Then send the authenticated documents to your agent, who files them together with household-registration documents. The applicants in the two Taipei cases submitted household registration transcripts, the deceased's deregistration transcript (除戶謄本) and a table of heirs (繼承系統表). If you hold only Japanese nationality and have no Taiwan household registration, ask the court or your agent first what will be accepted as proof of the parent-child relationship, and build the time for obtaining and authenticating Japanese documents into your schedule. Our column on instructing a Taiwan lawyer from outside Taiwan explains how documents signed abroad are authenticated.

Who inherits after you step aside?

A renouncing child's share goes to the others who inherit alongside that child (Article 1176, paragraph 1). If all the children renounce, the grandchildren inherit (paragraph 5). If everyone in a rank renounces, the next rank takes over: the deceased's parents, then siblings, then grandparents (paragraph 6). So if you have children of your own, they are next in line. A surviving spouse inherits separately from these ranks (Article 1138), so your mother, if she is living, would need her own renunciation.

Each person who becomes an heir this way has three months from the day he or she learns of it to renounce (paragraph 7). The heir who renounced first must notify in writing those who become heirs as a result, unless notice is impossible (Article 1174, paragraph 3). Work out who comes next before you file, and agree on dates with relatives in Taiwan and Japan. The order of heirs and their shares are set out in our guide to Taiwan inheritance and parental rights.

If you are preparing a renunciation in a Taiwan court from Japan, you can email Hovering International Law Firm at wei@hoveringlaw.com.tw with the date of death, the date you learned of it, your parent's last address in Taiwan, and who the other heirs are. This column is general information; the answer in a particular case depends on the actual documents and dates.
