Me and Ex split when DD was born. DD needs to be registered and ex wants her to have his surname. I am unsure wether to do this or not, I know he’ll be in DD’s life, but where our relationship is so uncertain I’m worried about giving her his surname. I feel as though I’d be doing it solely for him and his family who want DD to have their surname too. I feel really pressured or am I making this a big deal for no reason? I feel like giving DD his surname to shut everyone up. Any advice please?
