Civil Partnership Conversions

Civil Partnership Conversion

From Wednesday 10 December 2014 couples in a civil partnership will be able to convert their civil partnership into a marriage.

Civil partners will be able to choose to convert in one of two ways. They may choose a 'standard conversion' or a 'two-stage conversion' including a non-statutory ceremony to celebrate the event.

Standard Conversion

The standard conversion is a simple administrative procedure which is completed by both partners in attendance at a Register Office. The couple will complete a conversion declaration document and sign to say they wish for their civil partnership to be converted into a marriage.

If couples wish, they may also say the declaration wording to one another, but this is optional. Then the marriage will be registered and a certificate issued.

Couples will need to present the following documents: 

  • Evidence of their current name and date of birth, preferably passports 
  • Evidence of their current address which must be dated within the last three months (e.g. a utility bill or council tax statement) 
  • Their original civil partnership certificate
  • £4.00 cash for each copy of the marriage certificate they would like to purchase.

Two-stage Conversion

This is where couples attend a Register Office to complete the conversion declaration and show their identification documents (as listed in the standard procedure). Then they will have a celebratory ceremony, including the signing of the declaration at a later date (within the following 12 months). The ceremony may take place in any of the following venues:

  • In a Register Office 
  • In an approved venue that is licensed for marriage
  • In a religious building that is registered for the marriage of same sex couples
  • Or in a building where a ceremony according to the Jewish faith or the Society of Friends is to immediately follow the conversion.

Following the ceremony the marriage will be registered and a certificate will be issued.
