Converting a registered partnership into a marriage

If you have a registered partnership, you can convert it into a marriage.
The registrar will draw up a new certificate. This will terminate your registered partnership and your marriage will commence. After the conversion, you will be officially married. Not all countries recognize the conversion certificate as a marriage certificate. Please check with the government of the country concerned. Apply for the conversion online.

Description

To convert a registered partnership into a marriage, you must sign the conversion certificate. The conversion certificate is proof of the marriage. Once you have signed the certificate, the partnership is converted into a marriage. The conversion certificate is entered in the register of marriages.

You can request a ceremony (for example, in the wedding hall). No witnesses are required, and you do not have to say "I do." However, there will be a charge for this service.

Nothing will change for children born before the conversion. The conversion may have consequences for your assets. You will need to consult a notary about this.
