A same sex couple who have had a civil partnership can convert to a marriage either by simply completing the necessary paperwork (standard conversion) or by also including a ceremony (extended conversion).
This is a simple administrative process which involves attending an appointment, completing an application form and signing a declaration at our register office in Crawley.
This is a two-step process:
- Step 1 - Attend an appointment at our register office in Crawley.
- Step 2 - Sign a declaration as part of a separate personalised ceremony. This can take place at any venue licensed for civil same-sex marriage ceremonies in England or Wales.

An extended conversion will cost £27.00 per couple, payable at the application stage, plus the cost for the registrars to attend the chosen venue.
For West Sussex venues see our ceremony fees page.

As with all legal events, you will be asked to produce evidence of your full name, nationality, age and current address. You will also need the civil partnership certificate.
