Civil partnership to marriage

Civil partners have the choice of a simple conversion or a conversion with a renewal of vows ceremony. The civil partnership must have been registered in England and Wales or overseas in a consulate or armed forces base, where the civil partnership was registered according to the laws of England and Wales.

All existing civil partners wishing to convert to a marriage, will have to pay a fee of £45 for a conversion, plus £11 for each certificate.

Simple conversion

For a simple conversion, you'll need to:

  • book an appointment, and both individuals must attend in person at the register office
  • provide proof of identity and current address and your current civil partnership registration certificate.

You'll also have to sign a declaration to confirm that:

  • you haven't dissolved your civil partnership
  • both of you wish to convert your civil partnership.

The declaration must be signed at the register office.

Conversion and ceremony

To convert your civil partnership with a ceremony, you'll need to:

  • book an appointment in person at a register office, and both individuals must attend in person
  • provide proof of identity and your current address and civil partnership registration certificate.

The declaration will be signed, on a separate occasion, at an approved venue or religious building which has been registered for marriages of same sex.

A member of staff (superintendent or deputy registrar) from the Register Office will be required to attend the ceremony. The conversion will be registered with the Register Office and a marriage certificate issued.

If you're having a ceremony, you will need to pay ceremony fees plus the conversion fee of £45. There will be a fee of £11 for each certificate.
