Spouse’s surname

When you get married, your surnames will remain as they are unless you notify the authorities that you want to change them.

You can take the surname of one you as your common surname or combine your surnames into a common compound surname for you.

A compound surname may contain no more than two surnames. They can be combined with a hyphen or written separately.

You can take as your common surname

  • the surname of one of you
  • the compound surname of one of you or one surname from the compound surname of one of you
  • the pre-marriage surname of one of you (the surname that one of you had before getting married)

You can also take a new common compound surname combining your surnames, pre-marriage surnames or compound surnames.

However, you cannot take a surname you received from your previous spouse as a common surname or as part of a compound surname with your new spouse.

The surnames or compound surnames of the spouses may be different. For example, one of you can keep their own surname while the other one takes a compound surname combining both surnames.
