| Whether your babies daddy goes with you to the registry office or not you can give the baby either your last name or his. If you want to put him on the birth certificate then you can if he's not there but he does have to sign a declaration in order for you to do that (otherwise you could put anyone on there!)
If the baby DOES take your name and then you get married, as long as he's on the birth certificate then changing the name isn't a problem. If he isn't on the birth certificate then you would need proof that he's the Dad, but i wouldn't think he'd have to adopt him. |
