I am a registrar.
There’s some really inaccurate advice on here about surnames and “adding the father’s name”.
if you were coming to me to register your newborn baby and had your boyfriend with you, I would first look you square in the eyes and explain that you currently have sole parental responsibilities and if you chose to put Dad’s name on, he would have equal share to you. I would also be telling you that the surname on a birth certificate can never change (unless you marry him) so it would be deed poll only if you later change your mind and if you’ve added Dad onto the birth certificate, he would have equal say in that. If you choose to put Dad on your baby’s birth registration, he has completely equal responsibility with you and completely equal say over all decisions relating to health, education, travel, etc for 18 years. Think carefully.
If you register alone, you alone have parental responsibilities, but yes, be could go to court and be given them and you would be forced to reregister. He could
NOT have the baby’s surname though at that stage.
In my experience though, very few men bother at that point. They are mostly hot air.
If you register alone or you decide that he’d take this to court anyway (weigh up that possibility carefully), so you put his name on, the baby’s surname should be yours. It will then remain yours unless you do a deed poll or you marry him and choose to. If you initially register alone and then add Dad, the surname can NOT change unless you marry. There is no longer any facility for that to happen in registration law.
If you choose for your boyfriend to share parental responsibilities with you, he must attend the birth registration appointment with you.
Think very carefully, and regardless of that, use your own surname 😁
