DH registering birth with his surname

[ironic]

Anyone know if my DH can register our baby’s birth with a different surname (his own) to the one on hospital birth/discharge letter?
The situation is that DS was born very prematurely 200 miles from home (lesson to always cart your maternity notes around with you).
We’ve now finally made it home but couldn’t get appointment to register the birth before we left.
I really don’t want to have to travel back there with the tiny, still premature baby to register the birth. But we can’t work out if DH can go alone.
DS is called simply Baby Ironic on his hospital papers but we want to name him X Y DHsurname.
The registry office receptionist was very unhelpful when I called to ask what to do... can anyone help us avoid a wasted 400 mile round trip?!

If he’s married he can name the baby whatever he feels like, banana hammock or crap bag or anything that takes his fancy!

Can you not go to ur local office and register there and it gets sent off? Our hosp is on the borderline of local authorities. My daughter was born over in the other local authority but I could register her at mine and then it was sent off to them for the birth certificate?

We had exactly the same, we're married but I use my surname and not my married name, so my baby had my surname. Wasn't an issue when we went to register her at all.
