Which is correct: "together with their families" or "our families"?

Short answer

Both are correct. 'Together with their families' is more traditional and formal. 'Our families' is warmer and more modern. Choose the one that feels right for your invitation style.

There is no rule that makes one right and the other wrong. 'Together with their families' is the classic wording used on many UK invitations. It sounds gracious and includes both sets of parents without naming them. It works well for a formal wedding, especially if parents are contributing to the cost or hosting.

'Our families' is more personal and direct. It puts the couple at the centre and speaks from their voice. For example: 'Together with our families, we invite you to celebrate our marriage.' This feels warmer and suits a less formal or more modern invitation. It also works well if you have blended families, step-parents or relatives who are helping in different ways.

If you want to name parents, you can say 'Together with their parents, [names] and [names]' but that can get long. A good compromise is to use 'Together with their families' on the main invitation and thank specific people in a speech or on your wedding website. The key is to be consistent and make sure everyone who is helping feels acknowledged, but the wording itself is flexible.
