So. My husband got a call today from my FIL. My FIL said he got our invitation, went to Staples, bought paper that resembled our invitation, and printed more invitations. We got our invitations from Minted. He used these new invitations to invite more of his friends to our wedding. My husband told him that this was not ok at all and way out of line. We did not give his dad a limit on how many people he can invite, but we did tell him that if we ran out of invitations: that's it. No more people. His dad said what's done is done. The only thing his dad is paying for is the band. We allowed him to invite plenty of his family and friends (even his mechanic) which made our guest list skyrocket to over 300.
Do I have the right to be livid? Do I have the right to tell him to uninvited these people or else pay for them? What do I do?
