What happens at a renewal of vows ceremony
The ceremony itself can look very similar to a wedding with an exchange of promises and rings, and though this has sentimental value, the ceremony doesn’t have legal status.
It’s likely that your registrar will acknowledge the fact that you're already legally married or in a civil partnership during the ceremony.
The celebration is personal to you both and your relationship. You can include readings from other members of your family if you wish, giving close family and friends the chance to pledge their support and love. Take a look at some suggestions on how to personalise your ceremony.
