Choosing a child's last name

What is it?

With your 1st child, you can choose the last name. You can give your child your own last name or that of your partner. All subsequent children of you and your partner together will then automatically receive the same last name as your 1st child.

Before the birth or at the birth registration, you record the surname with the municipality.

How does it work?

If you do not choose a surname or record it with the municipality in time, the law determines which surname your child will have. Which name that is depends on your personal situation. See below which situation applies to you.

Husband and wife, married or registered partnership

Your child will automatically receive the father's last name. If you want your child to have the mother's last name, you must register it together with the municipality before or during the birth registration.

Two women, married or registered partnership

  • If the mother is pregnant by an unknown donor, your child will automatically receive the surname of the paired mother. This is only possible if the paternal mother automatically becomes a legal parent at birth. This requires a declaration of parenthood. If you want your child to have the birth mother's last name, you must register this together at the municipality.
  • If the mother is pregnant from a known donor and the duo mother acknowledges your child, your child will automatically receive the birth mother's last name. If you want your child to have the duo-mother's last name, you must register this together at the municipality.

Parents who are not married and not registered partners

Your child will automatically receive the mother's last name. If you want your child to have the father's or duo mother's last name, the father or duo mother must acknowledge your child. When acknowledging, you will then choose the last name together.

Family of two men

At the moment of a child's birth, there is always a mother. Motherhood can only end through adoption. With adoption, you can choose the last name of your 1st child. This is done in court. Subsequent children of you and your partner together will have the same last name.

What to do.

You and your partner go to the municipality together to have your child's last name recorded.

Note! Often the mother cannot be present at the birth registration. It is therefore best to visit the municipality together before the birth.

What do I need?

  • valid proof of identity of yourself
  • valid ID of your partner

How long does it take?

The municipality records your child's last name immediately.
