Renunciation of inheritance (相続放棄, sōzoku hōki) is a legal procedure in which a person who is entitled to inherit states to the family court that they wish to waive all rights and obligations under the estate — including both assets and debts. It is commonly used when the deceased had significant debts, or when the estate consists only of burdensome property (such as rural land with high maintenance costs and no market value). The critical rule: renunciation must be filed within 3 months of learning that you are entitled to inherit.
The 3-Month Deliberation Period
Renunciation must be submitted to the family court within "3 months from the day the heir learned that the succession had opened for them" (Civil Code Article 915).
This clock typically starts on the day the heir learned of the death. For heirs who were unaware of their entitlement, it starts from the day they learned they were an heir.
Once filed, renunciation cannot be withdrawn. The decision to renounce is permanent and irreversible — take care before proceeding.
Documents Required for the Application
- Application for renunciation of inheritance (use the family court's standard form)
- Family register entry showing the deceased's death (certified copy)
- Applicant's family register entry
- Residence record deletion certificate (or family register attachment) of the deceased
- Revenue stamps: ¥800 per applicant, plus return postage stamps
- Additional family register entries establishing the relationship (for children, siblings, grandchildren, or other relatives by representation)
Where to File
The application is filed with the family court having jurisdiction over the deceased's last address. If the court is in a distant location, you may apply for the case to be transferred to the family court near the applicant's address.
Effects and Key Points
- Deemed never to have been an heir: A successful renunciation retroactively removes the person from the line of inheritance as of the date of death.
- Inheritance passes to the next in line: If all children renounce, the estate passes to the parents (ascendants); if the parents also renounce, it passes to siblings. This chain can surprise relatives who were not informed — it is important to notify affected family members in advance.
- Do not dispose of estate property before renouncing: If an heir sells, consumes, or discards estate property before renouncing, this constitutes "unconditional acceptance" (単純承認) under Civil Code Article 921, and the right to renounce is forfeited.
- The 3-month period can be extended: If you cannot complete the investigation of estate assets and liabilities in time, you may apply to the family court for an extension of the deliberation period (Civil Code Article 915, Proviso).
- Life insurance and survivor's pension are unaffected: A death benefit payable to a named beneficiary, and a survivor's pension, are not "estate assets" and may still be received after renunciation.
- Ongoing management duty may continue: Under 2023 Civil Code reforms, a person who has renounced may still owe a duty to manage estate property until another heir takes over management (Civil Code Article 940).
When to Consider Renunciation
- The deceased had substantial debts (consumer loans, bank loans, guarantee obligations)
- The estate consists only of property with high maintenance costs and no liquid assets
- The deceased was a guarantor for a business loan
- You wish to pass the full estate to another specific heir (note: an Inheritance Division Agreement may also achieve this)
