3rd pillar and divorce: sharing and consequences

Divorce is a situation that directly impacts your pension, including your 3rd pillar. In Switzerland, sharing rules differ depending on whether it is a pillar 3a (tied pension) or a pillar 3b (flexible pension). Understanding these mechanisms is essential to protect your financial interests.

Sharing of pillar 3a in case of divorce

Pillar 3a is subject to specific rules in case of divorce, defined by the Vested Benefits Act (LFLP) and the Swiss Civil Code.

Sharing principle

Pillar 3a assets accumulated during the marriage are shared equally between the spouses. This sharing applies regardless of the chosen matrimonial property regime (participation in marital property, community of property or separation of property).

• Assets before the marriage: remain the property of the account holder
• Assets during the marriage: shared 50/50 between the spouses
• Assets after the effective separation: remain the property of the account holder

Pillar 3a sharing procedure

The sharing of pillar 3a follows a precise procedure:

1. The judge determines the amount to be shared in the divorce judgment
2. The pension institution (bank or insurance) receives the court order
3. The transfer is made to a 3a account or a vested benefits account of the beneficiary spouse
4. No tax is levied on the transfer between spouses in the context of a divorce

Treatment of pillar 3b during divorce

Pillar 3b (life insurance or free savings) is treated differently because it falls under ordinary matrimonial law rather than occupational pension law.

According to the matrimonial property regime

• Participation in marital property (default regime): the surrender value of the 3b insurance is part of the marital property and is subject to sharing
• Community of property: all 3b assets are shared
• Separation of property: each spouse keeps their own 3b assets

Pillar 3b beneficiary clause

Unlike pillar 3a, pillar 3b allows free designation of beneficiaries. After a divorce, it is imperative to update the beneficiary clause of your 3b contracts to prevent your ex-spouse from remaining as beneficiary.

Concrete calculation example for 3a sharing

Let's take a practical example to illustrate the sharing mechanism. Marc and Sophie marry in 2010 and divorce in 2024. Marc holds a 3a account with a balance of CHF 120'000 at the time of the divorce.

The CHF 25'000 accumulated before the marriage remains entirely Marc's property. The CHF 95'000 accumulated during the marriage is shared equally: Sophie receives CHF 47'500, transferred to her own 3a account or a vested benefits account. Marc keeps the remaining CHF 72'500 (CHF 25'000 from before marriage + CHF 47'500 being his half of the marital assets).

Important: interest and returns generated on assets during the marriage are also part of the amount to be shared. It is therefore essential to keep 3a account statements dating from the day of the marriage as proof of the initial balance.

Divorce timeline and 3a assets

The 3rd pillar 3a sharing process follows a precise timeline. Here are the key stages and deadlines:

Separation phase

During the de facto separation, each spouse continues to contribute to their own 3a account. The question of sharing only arises at the time of the divorce judgment. However, the date of the effective separation (not the date of the judgment) determines the end of the sharing period in most cases.

Legal proceedings phase

1. Divorce petition: the spouses (jointly or individually) file the petition with the competent court
2. Asset inventory: the court asks each pension institution for a statement of 3a assets accumulated during the marriage
3. Conciliation hearing: the spouses attempt to reach an agreement on the sharing, including 3a assets
4. Divorce judgment: the judge sets the amount to be transferred and the receiving pension institution
5. Transfer execution: the 3a institution executes the transfer within 30 days of receiving the enforceable judgment

After the judgment

Once the sharing is completed, each ex-spouse is free to manage their 3a assets independently. It is strongly recommended to consult the 3rd pillar withdrawal conditions to know the options available after a divorce.

Tax consequences of sharing

The sharing of the 3rd pillar in the context of a divorce has specific tax implications:

• Tax-free transfer: the transfer of 3a assets between spouses in the context of a divorce is tax-exempt
• Withdrawal tax: the withdrawal tax will apply when the beneficiary actually withdraws the funds, under the usual conditions
• Tax deduction: after the divorce, each ex-spouse can continue to deduct their 3a contributions from their taxable income, based on their professional situation

Practical advice in case of divorce

1. Take stock: gather all documents relating to your 3a and 3b assets (account statements, insurance policies, subscription dates)
2. Identify the marriage date: it determines the sharing period for pillar 3a
3. Consult a specialist: a pension advisor can help you assess the impact of the divorce on your retirement
4. Update your beneficiaries: modify the beneficiary clause of your 3b contracts as soon as the divorce is finalized
5. Recalculate your needs: use our retirement capital calculator to assess your new situation
6. Rebuild your pension: after the sharing, increase your contributions if possible to compensate for the loss

Impact on retirement planning

Divorce generally halves the 3a assets accumulated during the marriage. It is therefore crucial to replan your pension as soon as possible after the divorce. Some options:

• Maximize your annual pillar 3a contributions (CHF 7'258 in 2026 for employees affiliated with a 2nd pillar)
• Consider a complementary pillar 3b for more flexibility
• Check your pension gaps at the 2nd pillar level and consider a buy-back
