If you got married abroad to a person of the same sex before 1 July 2022, it will be treated in Switzerland as a registered partnership, not as a marriage.

If you have entered into a marriage abroad with a person of the same sex since 1 July 2022, it will be recognised as a marriage in Switzerland and entered as such in the civil register.

Surname

In principle, each partner kept their own surname.

It was also possible for two people of the same sex entering into a registered partnership to choose the surname of either partner as the common surname.

Citizenship

Unlike marriage, a registered partnership does not entitle the foreign partner of a Swiss citizen to simplified naturalisation.

However, if you are the foreign partner of a Swiss citizen, you have advantages under the ordinary naturalisation procedure. You can apply for ordinary naturalisation after three years of registered partnership if you have lived in Switzerland for five years including the year preceding your naturalisation application. The cantonal migration authority can provide you with detailed information on this subject.

Children

If you are living in a registered partnership, you and your partner are not permitted to adopt a child together or use medically assisted reproductive techniques to become parents together.

However, you can adopt your partner's child if you have been living in a registered partnership for at least three years and have provided for the child's care and upbringing for at least one year.

If your partner has children, you must in any case support him or her as a parent and can also act on your partner's behalf if he or she is ill or temporarily absent.

If you and your partner are both parents because you have adopted your partner's child, you have the same parental rights as a married couple.

Property and debts

In principle, the assets (and debts) of the two partners remain separate.

However, you and your partner can enter into a property agreement, which must be certified by a notary, in which you can regulate how your assets are managed.

Taxes

Partners in a registered partnership must fill in their tax returns together and pay taxes together.

Death

In the event of the death of your partner, you have the same rights as a widow or widower in a marriage:

• If you have minor children, you receive a widow(er)'s pension from the OASI.

• You are also entitled to a pension from your partner's occupational pension fund if you have to support a child or if you are over 45 years old and your registered partnership lasted for at least 5 years.

• You are your deceased partner's legal heir. For further information, you should consult the page on Succession.

A marriage between two persons of the same sex that has been celebrated abroad according to the rules in force in the country concerned is currently recognised in Switzerland as a registered partnership.

For general information on registered partnerships, consult the frequently asked questions page on the Federal Office of Justice website.

For information on the recognition of a registered partnership entered into abroad or on the conversion of a registered partnership into a marriage, you can contact the civil register office or a Swiss representation abroad.

If you have questions about your own registered partnership or an agreement on managing a registered couple's assets, you can also contact a lawyer or notary of your choice.

In the popular vote of 26 September 2021, the Swiss accepted marriage for same-sex couples as well. Details of this vote can be found on the Swiss government’s  ‹Marriage for All› web page.
