How can I change my toddler's surname? He was given his father's name at birth but since then we have separated (never married). He did sign a voluntary paternity form at the hospital after delivery. We live in 2 different states so he only visits about 3 times a year and while he did pay $400 a month for the first year, he has stopped paying for the last 10 months. I don't want his money so do not wish to go to court for support payments. I just want to give my son my surname or at least a hyphenated one with both names.
I appreciate the advice.
