Invite in-laws of siblings to your wedding? My FI has siblings and his parents have put the siblings in-laws on their guest list. I wasn't sure if this was something that's common or not, so I didn't want to make a stink about it quite yet, haha. I have never met any of his siblings in-laws and FI has only met them once, at the weddings, so personally, we don't see it as necessary. Just wanted to hear from anyone else if these are people that normally make the guest list. Thanks.

Ugh. My DH's parents had us invite his brother's inlaws. Idk if it's a Polish/eastern european thing, but i thought it was really annoying. They paid for the guests, so they were invited, but I just don't get it.
I think it depends on the family relationship, to be honest. We live far away from FI's family, but when FI's younger sisters get married some day, I'm sure FI's older sister's in-laws will be invited since they all do holidays together now anyway.
