What do witnesses do at a wedding?

Answered by the UK Wedding Websites editorial team · Updated 2026-10-12 · For the bridal party

Short answer

Witnesses sign the marriage document to confirm the ceremony took place and that the couple entered freely. They are present throughout, watch the vows, and act as official proof of the marriage.

Your witnesses are the official proof that your marriage happened. They must be there for the whole ceremony, from start to finish, and watch you exchange your vows. They do not need to be related to you, but they must be able to understand what is happening. Most couples choose close friends or family members who can speak clearly and write their names. You will need two witnesses for a civil ceremony in England, Wales and Northern Ireland, and two aged 16 or over in Scotland. After the vows, the registrar or celebrant will ask your witnesses to sign the marriage schedule or document. This signature is what makes the marriage legally recorded. The witnesses do not have to give a speech or read anything, though some couples ask them to hold rings or readings as a honour. You can choose anyone you trust, and they can be the same people who help with other parts of the day. Make sure they know the time and place, and that they can stay for the whole ceremony without rushing off.
