Swiss Bank Account After Death: How the Freeze Works and How to Unfreeze It

The single most financially damaging mistake families make after a death in Switzerland is rushing to tell the bank. The moment a Swiss financial institution learns that an account holder has died — whether from the family, the civil registry, or a newspaper obituary — it is legally required to freeze every account associated with that person. Immediately. Completely.

Savings accounts, checking accounts, investment portfolios, standing orders for rent, utility payments, insurance premiums — all stopped. Credit cards are cancelled on the spot. If the surviving spouse depends on those accounts for household expenses, this creates an instant financial crisis that can last months.

Why Swiss Banks Freeze Accounts

Swiss banks freeze accounts under FINMA (Swiss Financial Market Supervisory Authority) and anti-money laundering regulations to protect the estate for the legal heirs. The bank cannot release funds to anyone until it knows, with legal certainty, who the rightful heirs are and what share each is entitled to.

This isn't discretionary — it's a legal obligation. UBS, Credit Suisse successor entities, cantonal banks, PostFinance, and every other Swiss financial institution follow the same rule.

How Long the Freeze Lasts

The freeze remains in place until the heirs present the bank with two documents:

1. The Certificate of Inheritance (Erbschein) — issued by the competent cantonal court or inheritance office, confirming who the legal heirs are and their respective shares
2. A unanimous, hand-signed asset-distribution instruction — a letter signed by every single heir telling the bank exactly how to divide and transfer the funds

The Erbschein typically takes 6 to 12 weeks to obtain, and that clock doesn't start until the three-month reflection period expires. In practice, most families wait 4 to 6 months before accounts are unfrozen.

For complex international estates with heirs in multiple countries, the process can take significantly longer.

What to Do Before You Notify the Bank

If the surviving partner needs access to the deceased's accounts for daily living expenses, take these steps before the bank learns of the death:

Check for a "beyond death" power of attorney: A standard bank power of attorney (Bankvollmacht) expires automatically on death. However, if the deceased executed a power of attorney that explicitly states it remains "valid beyond death" (über den Tod hinaus gültig), the authorized person retains access even after the account holder dies. Check the deceased's banking documents carefully.

Secure independent liquidity: If the surviving spouse has their own accounts, ensure those are funded. Transfer household expense coverage to accounts not in the deceased's name before notification.

Understand joint account rules: Joint accounts (Compte joint / Gemeinschaftskonto) are not automatically accessible to the surviving co-holder after a death. The bank typically restricts the account, allowing the survivor access only to their verified share — and only if a pre-authorized post-mortem power of attorney exists.

The Exception: Pillar 3a Pension Assets

Private pension assets held in Pillar 3a accounts are a critical exception. These funds do not form part of the general probate estate. Instead, they pay out directly to designated beneficiaries following a statutory priority order:

1. Surviving spouse or registered partner
2. Direct descendants, or persons who received substantial financial support from the deceased
3. Parents
4. Siblings
5. Other heirs

If the deceased designated an unmarried partner as a 3a beneficiary during their lifetime (by notifying the pension institution in writing), that partner receives the funds directly — bypassing the Erbschein requirement and the estate freeze entirely.

What Banks Require to Unfreeze

When you're ready to approach the bank with the Erbschein:

• Original Certificate of Inheritance (not a copy) — some banks accept a certified copy
• Unanimous distribution instruction signed by all heirs — specifying account-by-account what to transfer, close, or liquidate
• Identification for all heirs (passport copies, sometimes apostilled)
• Death certificate — the International CIEC format is generally accepted

If any heir refuses to sign the distribution instruction, or if heirs disagree on how to divide assets, the bank will not release funds. The dispute must be resolved — by mediation, negotiation, or ultimately through court proceedings — before the bank acts.
