My brother and his ex-wife have been divorced for about 12 years. Our family has remained friends with my ex-sister-in-law and her new husband. They've even spent some time on family vacations with all of us and so we're inviting them to the wedding They have joint custody of my niece and nephew with my brother. My question is whose invitation should I list the kids' names on? My brother's or his ex-wife's or both? I don't want to offend either one. Both kids are in the wedding so I know they'll be there. Just didn't know the etiquette for the invites.
