Renouncing Inheritance: Missed Deadline? Anfechtung 2026

Take a deep breath: a missed deadline is rarely the end

If you missed the six-week deadline while trying to renounce an inheritance, you are far from the first person in that position — and it is not a dead end. Most readers of these lines have already had a few sleepless nights. Perhaps you only just learned about the deceased's debts. Perhaps a letter from the Nachlassgericht (German probate court) caught your eye weeks late. The worry that you may now have to answer personally for those liabilities is understandable; in most cases it is also unfounded.

The good news first. German inheritance law provides a clearly regulated way out. If you missed the Ausschlagung because you were mistaken about material circumstances, you can challenge the acceptance retroactively. This is no theoretical last resort. It is an established remedy that, under the 2026 state of case law, regularly succeeds.

This guide shows you when the deadline actually starts running (often later than you think), the conditions under which an Anfechtung under § 1954 BGB works and which steps matter now.

The six-week deadline: when does it really begin?

Many people only learn weeks or months after a death that they are entitled to inherit. The decisive point: the deadline for the Ausschlagung starts with your knowledge — the date of death is irrelevant.

Under § 1944 BGB, the deadline runs from the moment the heir gains knowledge of the inheritance and the ground of appointment. Two conditions must be satisfied at the same time:

1. Knowledge of the death: You must know that the person has died.
2. Knowledge of your status as heir: You must know that you have been called as an heir.

Only once both conditions are present do the six weeks begin to run. In practice that means: a nephew who becomes heir at the end of a chain of renunciations often still has months — even if the death itself was half a year ago.

Four scenarios in which the deadline begins later

Scenario 1: no contact with the deceased

You had not been in touch with a distant relative for years. News of the death reaches you only months later through the Nachlassgericht. Here the deadline starts when the notification arrives. The date of death itself does not matter.

Scenario 2: the will was unknown

You are a statutory heir and knew about the death. Later a will is opened that changes your share of the estate. Where succession is testamentary, the deadline begins only when the Nachlassgericht communicates the will. A practical safety margin: count on four to six weeks between the opening of the will and service on all parties.

Scenario 3: prior heirs renounce

Three siblings of the deceased have renounced the inheritance. As a result, you move into the line of succession as a nephew or niece. Your deadline begins only once you learn of the earlier renunciations. In large families this can stretch the overall chain of renunciations to between six and twelve months.

Scenario 4: residence abroad

You live abroad, or the deceased had their last domicile outside Germany. In either case the deadline extends to six months (§ 1944 para. 3 BGB). That gives you considerably more time to examine the situation of the estate.

Deadline missed: the Anfechtung under § 1954 BGB

Once the deadline has expired, you are treated as the heir. The inheritance is deemed accepted. There is a way out though: challenging the omission.

How the Anfechtung works

The legal basis is § 1956 BGB (Anfechtung of the omission of the Ausschlagung deadline); the six-week deadline for filing the Anfechtung, running from knowledge of the ground for challenge, follows from § 1954 BGB. The heir may therefore challenge the omission of the Ausschlagung deadline where they were mistaken about the accrual of the inheritance or about material facts (for example over-indebtedness). The Anfechtung has the same effect as a timely renunciation. You are treated retroactively as if you had renounced in time.

Conditions for a successful Anfechtung

The courts impose strict requirements. Not every gap in knowledge justifies an Anfechtung:

• Material mistake: You did not know about substantial circumstances of the estate. Examples: unknown debts, unknown guarantees, undisclosed tax demands.
• No negligence: The lack of knowledge must not stem from a lack of care. Anyone who ignores the estate although they could have looked into it cannot later invoke a mistake.
• Causation: The mistake must have been the reason why you let the deadline pass. If you would have accepted even with full knowledge, the Anfechtung fails.
• Deadline: The Anfechtung window is six weeks from knowledge of the ground for challenge. You must not miss this deadline a second time.

Recognised grounds in the case law

A concrete worked example: when an Anfechtung is worth it

Mrs M. inherits from her uncle an account with 15,000 EUR. She accepts the inheritance and spends part of the money on a family celebration. Three months later, an insolvency administrator contacts her: the uncle had stood guarantor for a loan of 180,000 EUR, which now falls due.

On the arithmetic, the apparent surplus of 15,000 EUR turns into a deficit of 165,000 EUR. Mrs M. can challenge under § 1954 BGB, provided she neither knew of the guarantee at acceptance nor should have known. The six-week Anfechtung window runs from the day the insolvency administrator gives notice. The court fees at the Nachlassgericht are between 30 and 50 EUR in 2026 — set against potential liability of 165,000 EUR, that is a practical no-brainer in favour of the Anfechtung. The money already spent has to be returned by Mrs M. to the true heirs or to the insolvency administrator under the rules on unjust enrichment (§§ 812 ff. BGB).

Step by step: how to proceed

Step 1: stay calm and check the deadline

First check whether the deadline really has expired. Count the six weeks from the day on which you demonstrably learned of the death and of your status as heir. Not from the date of death itself.

Step 2: identify the ground for Anfechtung

List every circumstance you were unaware of at the time the deadline expired. The more concrete and documentable the mistake, the better the prospects. Collect supporting evidence: bank statements, loan agreements, tax notices addressed to the deceased, letters from collection agencies.

Step 3: declare the Anfechtung

The Anfechtung must be declared to the Nachlassgericht. The form mirrors that of the renunciation declaration: in person, recorded in writing at the Nachlassgericht, or in publicly attested form (§ 1955 BGB). Guidance on the correct wording is set out in the guide Template and form for the Erbausschlagung, which also explains the formal requirements in detail.

The declaration must contain:

• Your full name and address
• Name and date of death of the deceased
• An explicit statement that you challenge the omission of the Ausschlagung deadline
• The ground for the Anfechtung, described in concrete terms
• The point in time at which you learned of the ground for the Anfechtung

Step 4: obtain legal advice

The Anfechtung is legally demanding. A misstated case can ruin the prospects for good. Have the chances of success reviewed by a lawyer before you file the declaration. Advisory costs of typically 200 to 600 EUR are out of all proportion to the debts you would otherwise take on as an heir.

Special cases when calculating the deadline

Minor heirs

For children under 18, the legal representatives act on their behalf. The deadline starts when the parents learn of the death and of the child's status as heir. A renunciation for minor children additionally requires the approval of the Familiengericht (family court) (§ 1643 para. 2 BGB).

Calculating the deadline under §§ 187 ff. BGB

The deadline starts on the day after the moment of knowledge. It ends with the close of the final day of the deadline. If the final day falls on a Saturday, Sunday or statutory holiday, the deadline extends to the next working day (§ 193 BGB).

Example: You learn on Monday, 1 April 2026, of the death. The deadline starts on Tuesday, 2 April 2026. It ends on Tuesday, 13 May 2026. If 13 May falls on a holiday, the deadline extends to the next working day.

Multiple grounds of appointment

If you are called both as a statutory and as a testamentary heir, separate deadlines run for each ground of appointment. You can renounce the testamentary inheritance and accept the statutory one, or vice versa.

Common mistakes in the Anfechtung

1. Challenged too late: The Anfechtung deadline of six weeks runs from knowledge of the ground for challenge. Do not wait.
2. Ground for Anfechtung too vague: "I didn't know there were debts" is not enough. Name the concrete liabilities.
3. Own negligence: Anyone who fails to check the deceased's documents although they had access acts negligently.
4. Wrong court: The Anfechtung must be declared to the Nachlassgericht handling the estate, not to the local Amtsgericht where you live.
5. Formal defects: A simple email or a letter without notarial attestation does not satisfy the form.

Frequently asked questions

What does the Anfechtung at the Nachlassgericht cost?

Court fees for the declaration of Anfechtung are between 30 and 50 EUR in 2026. Add notarial costs if you have the declaration attested (around 20 to 30 EUR with a low estate value). A lawyer's advice costs between 200 and 600 EUR depending on the complexity — with debts in the five-figure range looming, a negligible amount.

Can I challenge even though I have already spent money from the estate?

Yes, in principle that is possible. The Anfechtung takes effect retroactively, although you have to return the assets you have already received to the true heirs or to the insolvency administrator. If the money has already been spent, the rules on unjust enrichment under §§ 812 ff. BGB apply. That is unpleasant, but usually still considerably cheaper than taking on the full debts.

How long does the Nachlassgericht take?

After receipt of the Anfechtung declaration, the Nachlassgericht reviews the facts. Processing time depends on the court and the complexity of the case — typical values are between four and twelve weeks. The legal effect of the Anfechtung, however, already arises upon receipt of the properly drafted declaration at the court, before the formal notice issues.

What about the funeral costs if everyone renounces?

Under § 1968 BGB, the heir bears the funeral costs. If the inheritance is renounced by all parties, the next of kin are bound by the regional burial statutes — regardless of their status as heir. Social welfare carriers cover the costs only where no relatives are financially capable (§ 74 SGB XII).

Do my children move into the line of succession if I renounce?

Yes, that is the standard case. A person who renounces is treated as if already dead at the time of the inheritance. Their own descendants take their place. With an over-indebted estate, the whole family generally has to renounce — children likewise within the six-week deadline, represented by the parents and with the approval of the Familiengericht.

What distinguishes the Anfechtung from the Erbausschlagung?

The Erbausschlagung is the timely refusal of the inheritance within the six-week deadline. The Anfechtung under § 1954 BGB is the subsequent removal of an (often unwitting) acceptance after the deadline has expired. Economically the result is identical, although the Anfechtung requires a substantive ground of mistake — the bare fact of having missed the deadline does not suffice.

Can I withdraw the Anfechtung later?

No. Once declared, the Anfechtung is final. It takes effect upon receipt at the Nachlassgericht. That is why it is decisive to review the consequences precisely beforehand — particularly when the estate also includes valuable components such as real estate or securities.

Next steps

Whether the deadline has actually expired in your case depends on the precise point at which you obtained knowledge. That question can only be answered on the individual facts. Where the Anfechtung of a missed Ausschlagung deadline is off the table, an alternative may be a challenge of a will on grounds of mistake or duress.

Start by gaining an overview with the Erbschafts-Navigator for the inheritance case. Read also the detailed guide on the Erbausschlagung with deadline, costs and procedure for the underlying rules. Or arrange an initial consultation to review your Anfechtung options to discuss your individual options within the running deadlines.

The picture in 2026 is clear. Missing a deadline does not automatically mean you have lost everything. With the right legal advice, in many cases what is economically decisive can still be saved — the separation from an over-indebted estate.
