Revoking an earlier will or replacing it with an updated testamentary disposition is a fundamental right enjoyed by every capable testator under Swiss law. Under Articles 509 to 511 of the Swiss Civil Code (CC), you are entitled to cancel or amend your will in whole or in part at any time during your lifetime. However, because inheritance disputes can paralyze estate administration for years, executing a revocation requires strict compliance with statutory formalities.
In practice, drafting a new will without an explicit revocation clause is one of the most frequent causes of Swiss probate litigation. Under Art. 511 CC, a subsequent will only revokes an earlier one to the extent that their dispositions are irreconcilable. If clauses from an old will do not directly conflict with the new document, both remain legally effective side by side. To eliminate all ambiguity, testators should always incorporate an express revocation clause and destroy older documents.

Key Legal Rules for Revoking a Swiss Will:
- Art. 509 CC (Express Revocation): The safest legal standard is inserting a clear revocation clause at the beginning of your new handwritten will («I hereby revoke all previous testamentary dispositions in full»).
- Art. 510 CC (Physical Destruction): Tearing up, burning, or shredding the original holographic will revokes it immediately.
- Official Deposit Trap: If your previous will was deposited with a cantonal authority (e.g. Justice of the Peace, Notariat, or Probate Office), destroying a home copy does NOT cancel the deposited original. You must retrieve it formally.
- Mandatory Handwritten Execution: Any new will or written revocation must strictly comply with Art. 505 CC: handwritten from start to finish, dated, and signed by you.

The Swiss Civil Code provides three distinct mechanisms for revoking or altering an existing will:
A. Express Revocation in a Subsequent Will (Art. 509 CC)
This is the gold standard of estate planning in Switzerland. In a newly prepared handwritten will, you insert an opening clause declaring that all previous wills, codicils, and testamentary declarations are fully null and void. This creates absolute certainty for probate authorities.
B. Physical Destruction of the Original Document (Art. 510 CC)
Pursuant to Art. 510 Para. 1 CC, a testator may revoke a will by destroying the document. Tearing it into pieces, burning it, or shredding it physically establishes revocation. If only individual clauses are struck through, the surviving text remains valid unless the court finds that the crossed-out section alters the core intent of the document.
C. Incompatible Subsequent Will (Art. 511 CC)
If you create a subsequent will without expressly revoking the previous one, the new will replaces the earlier one only to the extent that their provisions are incompatible (Art. 511 Para. 1 CC). Unchanged appointments—such as the designation of an executor or specific legacy allocations—may persist unexpectedly.
| Revocation Method | Statutory Basis | Primary Benefit | Practical Pitfall |
|---|---|---|---|
| Express Clause in New Will | Art. 509 Para. 1 CC | Complete Legal Certainty | Requires drafting a full new handwritten document. |
| Physical Destruction | Art. 510 Para. 1 CC | Immediate Effect | Ineffective if an original remains deposited at court. |
| Subsequent Will without Clause | Art. 511 Para. 1 CC | Automatic Replacement | High litigation risk over non-contradictory clauses. |
| Official Deposit Withdrawal | Art. 510 Para. 2 CC | Register De-listing | Requires personal appearance with government photo ID. |
Expat Advisory: Updating a will should always coincide with a comprehensive personal estate review. A Swiss Advance Healthcare Directive specifies your medical wishes if you become incapacitated, while a General Power of Attorney allows a trusted family member or advisor to manage financial matters. If family loans exist, an Acknowledgment of Debt guarantees precise settlement upon division.
2. The Danger of Officially Deposited Wills
A dangerous mistake made by international residents in Switzerland is shredding their home copy of a will while leaving the officially registered document untouched. Under Art. 510 Para. 2 CC, if your previous will was submitted for official deposit and safekeeping of wills, the authority will open that document upon notification of death.
To prevent obsolete terms from governing your estate, you must contact the registry authority, present your passport or Swiss residence permit, retrieve the document, and deposit your newly drafted will in its place.
3. Exact Wording for the Revocation Clause
When drafting your new holographic will by hand, position the revocation clause at the very beginning:
I, [Full Name], born on [Date of Birth], citizen of [Country/Canton], residing at [Swiss Residential Address], declare this to be my last will and testament:
1. Revocation: I hereby expressly and entirely revoke all prior wills, codicils, and testamentary dispositions made by me. This document constitutes my sole and exclusive current last will.
Frequently Asked Questions
Can I revoke my Swiss will by typing and signing a cancellation letter?
No. Under Art. 505 CC, any testamentary statement—including a revocation—must be 100% written by hand. A typed, printed, or emailed cancellation letter is null and void under Swiss inheritance law.
Can an inheritance agreement (Erbvertrag) be revoked unilaterally?
No. An inheritance agreement is a binding bilateral contract. Unlike a will, it cannot be revoked unilaterally. Modifying or cancelling it requires mutual written consent or a new publicly notarized agreement between all contracting parties.
What should I do if my marital status changes?
A divorce automatically revokes statutory inheritance rights and testamentary benefits conferred on the former spouse under Art. 120 Para. 3 CC. However, to eliminate ambiguity regarding non-statutory gifts, drafting a new will with an express revocation clause is strongly recommended.
