Can I choose legally whether or not my son gets my last name over his father's? Or can the father…

you can choose the last name but the father can always take you to court and change it

@hermommy, what she said

I just spoke to my lawyer about this exact thing last week. you have a choice what your child's name is. Even if the father took you to court, and you had a valid reason for wanting the child to not have the fathers last name, then a judge will most likely keep it how you want it. I myself am not with my child's father,and never will be which is why my daughter will have my lastname. He has been inconsistent since day one and I don't feel like he is deserving enough of that.
