How do you invite a partner to a wedding?

Short answer

Invite a partner by naming them on the invitation alongside their partner, and be clear about whether plus-ones are allowed. This avoids confusion and shows respect for their relationship.

When you are making your guest list, decide early who counts as a couple. If two people are married, civil partners or living together, name both of them on the same invitation. If you are not sure about their status, ask them directly rather than guessing. A vague envelope often leads to awkward questions or people arriving alone.

For guests who are single, you can either invite them individually or offer a plus-one. If you want to keep the day intimate, it is kinder to say so clearly. You might write 'we would love for you to join us' without a plus-one, or reserve that option for long-term partners. Do not leave it to chance.

Name both partners on one envelope, using their preferred titles and spellings.
Send invitations to the household address if they share a home.
Mention event details for each part of the day, especially if partners are invited to the ceremony but not the reception.

If you are unsure about etiquette in a particular culture or faith, ask a trusted family member or check with your place of worship. The most important thing is that every guest feels welcome and knows exactly what is expected.
