Just sat down with my future Mother-In-Law and went over their side of the guest list.
She said that we needed to invite my future -sister-in-law's future parents. I've met my future sister-in-law's boyfriends parents once before. Both my fiance and I don't see why we need to have them at our wedding.
Is it etiquette to have my future sister-in-law's future parents come, as they will be part of our extended family (in the near but distant future).
Please send advise.
