I really don't want to invite my late mom's family to the wedding; grandma, grandpa, and uncle - grandparents hate each other, uncle hates the grandpa, and they all hate my dad. But there could be some major repercussions if I don't, like getting written out of the will or shunned for the rest of time. My grandpa also helped put me through college. Plus, with my mom having passed away, there's just that extra sore spot.
I don't mind if they come for the ceremony and then leave, you can't socialize there as much as you can on the dance floor. I was thinking of possibly printing different RSVPs for just the 3 of them that have check boxes asking which parts of the wedding they will attend; the ceremony and/or "the after party" (the reception), phrased specifically to deter the elderly two. They all probably want to avoid each other anyway so I think they'd actually appreciate an escape route, but they're so immature and petty that if they don't get an invitation, all hell would break loose.
I don't care if they find the RSVP rude because at the end of the day, I invited them, so they can't argue that. Has anyone else done this? Was it successful? Or is this a totally dumb idea?
TLDR; my mom passed away and her family is the worst and while I wouldn't mind them coming to the ceremony, I don't want them at the reception. Could I make RSVPs with check boxes for ceremony and/or reception attendance and cross my fingers they don't come to the reception?
