How late is too late to send out wedding invitations?

In the UK, sending invitations less than 6 weeks before the wedding is generally too late. Most guests need at least 8 weeks to plan, especially if they are travelling, need childcare, or have work commitments. If you send invitations with only a month to go, you risk a lower attendance and a stressful rush for replies. That said, sometimes life happens and you have to send late invitations, for example if a guest list changes or you have a short engagement. In that case, send them as soon as possible, and be upfront with guests. You can also send a quick email or text to close friends and family to give them a heads up, then follow with a formal invitation. For a very late invitation, under 4 weeks, it is acceptable to phone or email guests directly and skip the formal paper invite, though many couples still send one for keepsake value. Remember that your RSVP date must give you enough time to confirm numbers with your venue. If you are very late, consider asking guests to reply by email or phone to speed things up. The legal notice period for marriage in England and Wales is 28 days, but that is separate from invitations. Always aim for at least 8 weeks, and never less than 6, unless you have no other choice.
