How do you handle a plus-one who is a non-binary or gender non-conforming guest?

Send the invitation to the name your guest prefers. If you need to add a title, ask them which one they like. Do not put Mr or Mrs unless you are sure. Many people prefer no title at all. You can write the name on one line without any gendered wording.

At the wedding, do not make assumptions about their partner. A non-binary guest may have a partner of any gender, or no partner at all. If they bring someone, treat that person as any other plus-one. Seat them normally and introduce them by name only.

If you are unsure about pronouns, ask your guest in a kind, private way. Say you want to get it right. Most people appreciate being asked rather than being guessed at. If you make a mistake, apologise briefly and move on.

Some religious ceremonies or family customs use gendered language. If your wedding includes such elements, talk to your celebrant or venue early. For legal details, rules can vary, so check GOV.UK or your register office.
