Second-pillar (LPP) split on divorce — CC arts. 122-124e

Equal split of occupational pension assets accumulated during the marriage on divorce — calculation, exceptions, refusal, modification. Distinct from matrimonial property liquidation.

The split of the second-pillar (LPP) pension is one of the most financially significant — and most overlooked — elements of a Swiss divorce. For a 15-year marriage of a Geneva executive, the split can amount to CHF 200’000 to 500’000. It is mandatory (CC art. 122), independent of the matrimonial property regime, and rarely waivable without manifest inequity.

The principle

Pension assets accumulated by each spouse during the marriage under the second-pillar (LPP) system are split in half upon divorce (CC art. 122). The split applies regardless of:

  • the matrimonial property regime (participation in acquisitions, separation of property, community);
  • which spouse is the holder of the pension assets;
  • whether there are children.

The transfer is made directly from one pension fund to the other — no cash payout is permitted (except in narrow exit-from-Switzerland scenarios).

Calculation

The pension fund of each spouse issues a certificate showing :

  • the exit benefit at the moment of marriage;
  • the exit benefit at the filing of the divorce petition (CC art. 122);
  • the difference — accumulated during marriage.

This difference is split in half. Where one spouse has more accumulated than the other, the difference between the two halves is transferred from the higher to the lower account.

Exceptions to the equal split (CC arts. 124a, 124b)

The court can reduce or refuse the equal split where the result would be manifestly inequitable :

  • Very short marriage (typically under 5 years with no children).
  • Significant private retirement savings of the lower-share spouse, making the split unnecessary for retirement security.
  • Substantial fault of one spouse, where the fault directly relates to the pension build-up (rare and tightly scrutinised).
  • Cross-border situations where the foreign spouse already enjoys equivalent or superior pension protection in their country.

The exception is narrow — most divorces result in equal split.

Refusal scenarios

The split can be fully refused only in exceptional cases (CC art. 124b al. 2) :

  • the recipient already has substantially more pension assets than the contributor;
  • a refusal is justified by important reasons related to fairness, durably documented.

The case law applies these strictly: a refusal must be clearly supported.

Pension drawing vs. exit benefit

A complication arises when one spouse is already drawing a pension (retired or on disability) at the time of divorce :

  • The split applies to the value of the pension, not the monthly benefit.
  • The calculation uses actuarial tables to convert the pension into a capital equivalent.
  • The transfer can be made by periodic life-long pension share (rather than capital) — a less common but available solution.

For mixed cases (one spouse still working, the other drawing), the calculation must combine both methods.

Cross-border specifics

For binational couples, pension splitting raises additional issues :

  • No equivalent in French law — the French regime does not provide automatic equal split. A Swiss-French couple choosing French law (LDIP art. 61) transfers significant value to the higher-pension spouse.
  • Pillar 3 vs. Pillar 2 — only Pillar 2 (LPP) is automatically split. Pillar 3a (individual retirement savings) is treated as ordinary acquisitions and follows the matrimonial property regime.
  • Foreign pension funds — when one spouse holds pension assets abroad, the Swiss court can take them into account but cannot order the foreign fund to transfer. Compensation through other assets is the practical workaround.

Procedure

  1. Request the pension certificate from each fund as early as possible — banks are slow.
  2. Compute the marriage-period accumulation for each spouse.
  3. File the calculation in the divorce petition with supporting documents.
  4. Court order specifying the transfer amount and the receiving fund.
  5. Execution by the funds — typically within 90 days of the final judgment.

Common errors to avoid

  • Not requesting the certificate early — banks delay 4-8 weeks, sometimes blocking the timeline.
  • Confusing Pillar 2 with Pillar 3a — Pillar 3a follows the matrimonial property regime, not CC art. 122.
  • Accepting “I’ll keep my pension, you keep the house” without modelling the actuarial value — usually unfair to one side.
  • Missing the cross-border arbitrage between Swiss and French law for couples eligible to choose.

What you receive

  • A pre-divorce assessment of the pension assets on both sides and the expected split amount.
  • Modelling of the LPP-vs-house trade-off if the spouses want to negotiate alternatives.
  • Drafting of the petition clauses on pension splitting.
  • Follow-up with the pension funds after judgment to ensure execution within deadline.
