Under Swiss law, an invalid or defective will is not automatically void after the testator's death. Disinherited statutory heirs or beneficiaries of earlier dispositions must actively initiate an Action for Annulment pursuant to Article 519 of the Swiss Civil Code (CC) before the competent Swiss civil court. If the court establishes a critical formal flaw or testamentary incapacity, the will is set aside.

Key Legal Facts on Will Contestation in Switzerland:

  • Strict 1-Year Limitation Period: The action must be filed within 1 year of learning about the will and the ground for invalidity (Art. 521 CC).
  • Primary Grounds for Annulment: Formal defects (e.g., typed or un-signed wills), lack of testamentary capacity (Art. 467 CC), or defective consent (fraud, duress, or coercion).
  • Annulment vs. Abatement: Violating forced statutory shares is remedied by an Action for Abatement (Art. 522 CC), not total annulment.

1. Grounds for Annulment under Article 519 CC

A Swiss will can be challenged only on specific legal grounds defined by statute:

  • Lack of Testamentary Capacity (Art. 467 CC): The testator suffered from cognitive impairment, severe dementia, or acute delirium at the exact time of writing.
  • Undue Influence and Coercion (Art. 469 CC): The deceased acted under misrepresentation, deceit, or emotional duress imposed by a third party.
  • Unlawful or Immoral Dispositions: The clauses violate Swiss statutory prohibitions or public policy.

Frequently Asked Questions

Who bears the burden of proof when claiming lack of capacity?

Under Article 8 CC, the claimant challenging the will must prove incapacity. Because capacity is legally presumed (Art. 16 CC), robust medical evidence and contemporaneous witness testimony are mandatory.

Can foreign expats contest a Swiss will under foreign law?

Under the Swiss Private International Law Act (PILA), Swiss succession procedures apply to Swiss-domiciled decedents unless a valid professio juris choice of foreign national law was established in the will.
