I'm trying to figure out how to word the invitations when it comes to listing parents. We both come from divorced families. My father and stepmother (they share the same last name) are the only ones contributing to the wedding, however I want to include my mother and her partner (they have different last names) as well. I've been reading through different sites and etiquette guides, but it just further confuses me. Does anyone else have the same situation? How did you word your invites?
