You don't change your name in Denmark but at home. After the Danish wedding, every name option that German, Austrian or Swiss law provides is open to you. In Denmark itself, a name change is not possible without Danish residence. Note for Switzerland: there, the name declaration must be filed at the latest 6 months after the wedding.

Which name options do you have?

Both keep

Each partner keeps their current name.

Common marriage name

One partner's name becomes the common name; in Germany and Austria this can also be a name currently in use, in Switzerland only a pre-marriage name (Ledigname). Children you have together carry it automatically.

Double name

In Germany since 1 May 2025 also as the common marriage name of both, with or without a hyphen (e.g. "Müller-Schmidt"); in Austria with a hyphen. Not currently possible in Switzerland.

Where do you declare the name change?

In Germany: at the registry office of your place of residence; if you live abroad and were never registered as a resident in Germany, at Standesamt I in Berlin. The declaration must be officially certified and can be combined with the subsequent registration in the marriage register. In Austria: at the registry office at the main residence, ideally together with reporting the marriage. With the shared family name in mind, the Austrian embassy in Copenhagen recommends obtaining an Austrian certificate of no impediment or a certificate of single or civil status before the wedding, even though Denmark does not require one. In Switzerland: before the wedding at the civil-status office, afterwards together with the marriage documents at the Swiss representation or the cantonal supervisory authority.

Deadlines by countryIn Germany: no statutory deadline, but sensible to do it soon (passport, ID, tax class). In Austria you file the declaration at the registry office, ideally together with reporting the marriage. In Switzerland: at the latest 6 months after the wedding; without a declaration you both keep your names.

What does the name change cost?

The declaration itself is cheap; the new ID usually costs more.

CountryFee + new ID
Germany€25⁠–⁠60 + €46 (ID card) or €70 (passport)
Austria€35 + €76
SwitzerlandCHF 75⁠–⁠150 + CHF 145

Which documents do you need?

  • Danish marriage certificate (multilingual or certified translation)
  • Birth certificate of both partners
  • ID card or passport
  • Application form of the registry office
  • For Switzerland only: the original marriage certificate, no more than 6 months old; the Swiss representation's leaflet lists no apostille (more on registration in Switzerland)

What to update after the name change

  1. Passport and ID first

    The citizens' office issues your passport and ID in the new name; with them you can handle every other change in one go.

  2. Banks and insurance

    Change with the marriage certificate without formality.

  3. Health insurance, employer

    Income-tax class III/V or IV/IV.

  4. Contracts and memberships

    Telecom, electricity, clubs, online accounts.


Frequently asked questions

What couples often ask about this topic.

Do I automatically get my partner's name?
No. Even after the Danish wedding you must actively declare a common name: at the German or Austrian registry office, in Switzerland at the Swiss representation or the cantonal supervisory authority. Until then you both keep your current names. The name declaration is a separate step; in Germany you can combine it with the subsequent registration of your marriage in the German marriage register (Nachbeurkundung).
Where do I apply for the name change?
In Germany at the registry office of your place of residence; if you live abroad and were never registered as a resident in Germany, at Standesamt I in Berlin. In Austria at the registry office. In Switzerland before the wedding at the civil-status office, afterwards together with the marriage documents at the Swiss representation or the cantonal supervisory authority, at the latest 6 months after the wedding. Prerequisite: the Danish marriage certificate; in Germany and Austria without apostille (EU Regulation 2016/1191), and the Swiss representation's leaflet lists none for registering the marriage either; if you file directly with the cantonal supervisory authority, ask there beforehand. The name declaration is in person; in DE also possible in writing with a certified signature.
Which name options do I have?
1) Both keep their current names. 2) One takes the other's name as the common marriage name. 3) Double name: in Germany since 1 May 2025 also as the common marriage name of both, with or without a hyphen; in Austria as a common family name with a hyphen. In both countries, alternatively only the partner whose name does not become the marriage name can carry a double name. In Switzerland there is currently no double name; in March 2026 parliament agreed to bring double names back, but the date of entry into force is still open. What does not work: a completely new fantasy name (unlike in Denmark). International names (spellings, special characters) are generally allowed.
By when do I have to do the name change?
It depends on the country. In Germany there is no deadline, the declaration is possible even years later. In Switzerland you must file the name declaration at the latest 6 months after the wedding, together with the marriage documents at the Swiss representation or the cantonal supervisory authority; safest of all is to file it before the wedding at the civil-status office. In Austria it is best to settle this with the registry office when you report the marriage. Recommendation everywhere: do it soon, otherwise a double life with the old name on documents and the new name in contracts creeps in.
What do I have to re-apply for after the name change?
ID card + passport (€46 / €70, from age 24), driving licence (€25), update bank cards + contracts, health-insurance card, social-insurance ID (automatic). Your tax ID stays the same. All in all approx. €150⁠–⁠250 + 3⁠–⁠6 hours of administrative time.
