In a divorce, the shared property is often the largest and most emotionally charged point of contention. In Switzerland, around 40% of all marriages end in divorce — and in most cases a property is at the centre of it. This guide sets out your options, the tax consequences and the common pitfalls.
The three basic options
Option 1: Sell and divide the proceeds
The cleanest solution when both parties are in agreement:
- The property is sold at market price
- The mortgage is redeemed
- The remaining proceeds are divided according to the ownership shares
- Advantage: A clean break, no further dependencies
- Disadvantage: Children have to move, and property gains tax may apply
Option 2: Take-over by one partner
One partner takes over the property and buys out the other:
- Valuation by a neutral appraiser (→ Valuation Indicator)
- The mortgage is transferred to one partner — affordability must be met on a single income
- Buy-out = (market value − mortgage) × share of the departing partner
- Advantage: Children can stay in their familiar surroundings
- Disadvantage: A heavy financial burden for the partner taking over
Option 3: Retain co-ownership (rarely recommended)
Both remain owners, and one continues to live there:
- Compensation for use paid to the non-resident partner
- Advantage: No sale under time pressure
- Disadvantage: Continued joint financial dependency, potential conflicts
Tax consequences in a divorce
| Situation | Tax consequence |
|---|---|
| Sale to a third party | Property gains tax due (depending on the gain and the holding period) |
| Take-over by a partner | Usually tax-free (division under matrimonial property law) |
| Take-over + mortgage increase | No property gains tax, but a new affordability assessment |
| Change of ownership | Property transfer tax depending on the canton (often exempt in a divorce) |

The mortgage in a divorce: what the bank says
The bank is not obliged to cooperate in a divorce. Key points:
- Joint and several liability: Both partners are liable for the entire mortgage, even after the divorce — until they are formally released
- Affordability: The partner taking over must meet the affordability requirement on their own (→ Affordability Calculator)
- Early repayment penalty: Terminating a fixed-rate mortgage early incurs costs (often CHF 10'000–50'000)
- Refinancing: A new affordability assessment based on the current FINMA standard (5% imputed interest rate)
Common pitfalls
- Emotional sale: Under time pressure and against a backdrop of conflict, properties are often sold 10–15% below value
- No valuation: Without a neutral appraiser the value is often misjudged — in favour of the party who wants to buy
- Forgetting tax planning: Property gains tax on a short holding period (under 5 years) can amount to 30–50% of the gain
- Mortgage not settled: Joint and several liability remains in place until the bank formally releases the departing partner
- Children not considered: The best interests of the child may play a role in the court's allocation of the home
Recommended process
- Obtain a neutral property valuation (before negotiations)
- Have the tax consequences of all options calculated
- Check affordability for both scenarios (sale vs. take-over)
- Speak to the bank (mortgage release, refinancing)
- Draw up a divorce agreement with a clear provision for the property
- In the event of a sale: discreet marketing without a public listing
