My daughter has her dad's last name but I want to change it to mine. Throughout my pregnancy with her, I've always wanted to give her my last name, but her dad would fight with me if I did mention that. I believed when he said that he'll help me if I gave her his last name, but 20 months later.. he hasn't done anything for her. So I'm wondering what good are my chances of actually getting sole custody of my daughter? I've been told that I have to get sole custody in order to do so (changing last name) I'm a stay at home mom, I still nurse her and I'm applying for a part-time job so I can provide more for my daughter since her dad is not helping me whatsoever. What will the judge look at?
