Changes when you get married

Getting married has many personal and financial consequences.


Under the new law on names (in force since 1 January 2013), both spouses retain their surname after marriage, though they can also choose to take the same name.


Marriage no longer has any effect on a person's Swiss citizenship or on their cantonal or communal citizenship. Spouses retain their nationality when they marry. A Swiss woman who marries a Swiss man retains her existing cantonal and communal citizenship

Joint tax return

The incomes and assets of the two spouses are combined and declared in a joint tax return. The couple is taxed jointly for the entire tax year and not just from the date they got married.


If you do not make a will or testamentary contract, the law decides who will inherit your possessions and assets. Swiss law provides that spouses are entitled to a minimum share of the estate. The creator of a will cannot deprive their spouse of their minimum share of the estate.

Duty to inform

Each spouse has the right to demand information from the other concerning their income, assets and debts.


When a child is born, the husband of the child’s mother is the father unless proven otherwise. The parents also automatically have joint custody of the children.

Family home

Married individuals can only cancel the rental agreement on their family home with the consent of their partner, even when they are the sole signatory of the agreement.

Even when the couple live in a property belonging to one of the partners, the property cannot be sold without the consent of both partners.

Loyalty and support

The spouses owe each other loyalty and support. When you get married, you agree to provide moral and financial support to your partner where needed.
