We just moved from NJ to Florida 2 years ago. My oldest son is now 8 years old, the biological father has not been around for more than 7 of those years. I was never married to the biological father, but I have been receiving court ordered child support, but before that he was not paying. My husband and I would like my son to take my married name. Where should I start? The only contact we have to the biological father is through email. He constantly says he is in the service or going somewhere. Everytime we try to contact him he just blows us off. We have absolutely no idea where he is. What can we do?
