From October 1, 2017, a marriage between two people of the same sex can be registered. The conversion of an existing civil partnership into a marriage must be registered at the registry office of the place of residence.

Both civil partners and a registrar must be present for the conversion of an existing civil partnership into a marriage. The conversion must be signed and a marriage certificate with the date of conversion is then issued.

The conversion can take place without a ceremony in the offices of the registry office or with a ceremony in the wedding hall.

To register, simply send an e-mail to heiratenwiesbadende with the subject "Conversion of a civil partnership into a marriage". The e-mail should contain the name and register number of the civil partnership certificate (or the civil partnership certificate as an attachment if the civil partnership was established outside Wiesbaden).

It is important to indicate whether a conversion ceremony is desired.

Upon receipt of the e-mail, the registry office will send a proposed date for the conversion.

This service is also offered in the local administrations.
