Hey ladies I really need some help. Here's a quick background: FI never grew up with his dad in his life. A few years ago, his dad started reaching out to him. FI wanted nothing to do with his dad at first but decided to give his dad a chance. Well, a relationship developed and he's even grown closer to his dad's side of the family. FI didn't have his dad's last name and his dad insisted that he take on his last name. He paid for FI to change his name last year but it has not been processed as yet. He was told that it would take 3-8 months and next month will make 8 months since he's been waiting.
We want to order invitations soon and I wanted to know if we should go ahead and put his new last name on the invitations and all other wedding stationary. We'll be getting married in October.
