Convert a civil partnership into a marriage

Following the introduction of the Marriage (Same Sex Couples) Act, you can now convert your civil partnership into a marriage.

A simple conversion can take place at any of our main registration offices, or you can have a celebration and a ceremony at an approved venue.

You’ll need to book an appointment at the register office to sign a conversion into marriage declaration.

You’ll need to bring:

• your original civil partnership certificate
• proof of identity

It costs:

• £11 for a marriage certificate
• £45 to convert your civil partnership
• £27 for an appointment, if you have a ceremony
