The registration can only be done by someone who was present at the birth, i.e. your (birth) partner. It is a good idea to make an appointment so that you do not have to wait long at the town hall. Bring your proof of identity and your marriage booklet with you.
It is also possible to register your child online. For this, you will need: DigiD login details of both parents and any recognition certificate details. Within three days, your partner will need to come by to sign the birth certificate.
It is also important to register the baby with the health insurance company in the first week. This is free of charge and can be arranged simply by telephone.
