And does anyone know if you need to be resident in the UK to do so?
We (Me, DH and DS - DH is stepfather) live in Germany but we are all British citizens. We'll be visiting England in the summer and I'd like to get DS' name changed if possible.
He still has XP's name, but XP has had zero contact for the last four years (his choice, I've never stopped or prevented him) and DH has basically brought him up for the last five years. It would actually be easier for us all round if DH could just adopt him, but it's such a ludicrously lengthy process through the UK system that that seems unlikely. To go through step-parent adoption in Germany, changing the name is useful in advance, plus once his name is on his school records, apparently it's hard to change it.
I know that I need XP's permission since XP has parental responsibility but am (possibly naively) assuming this will be fairly easy to do if we're actually in the UK. I have no idea where he currently lives, but I know people who know him so could probably contact him.
Any advice/experience? I am totally dreading passport control since I took DH's name, I'm going to have to carry DS' birth certificate plus my marriage certificate and our proof of residence in Germany and then try to explain that the father is estranged and no I don't need a permission letter from him.
