How would i go about changing my sons last name?

my son is 10 months and has my exgirlfriends last name but i would like to have him has my last name. i'm already on the birth certificate and i signed acknowledgement of paternity. is it to late since i signed that?

How would i go about changing my sons last name?
You can't change his last name without her permission. If both of you have parental rights, then both of you have to sign the proper papers to change his name. Talk to her about it and see how she feels-if he lives with her most of the time and will continue to do so, it may be easier to for him to keep her last name, especially after he starts school. If she's ok with changing his last name, I would call the clerk of court in your county and find out what you need to do to go about filing papers to change it. You'll have to pay for the paperwork, court fees and things like that, but I don't think it will be too difficult if both of you agree.
Reply:contact your state agency. send them a letter. your name is on the birth certificate, so you stand a good chance
Reply:This depends on the State you live in most states say that after the child turns one then you cant change anything at all you would have to go to court for that. The state my son was born in says I can change it at any time before he turns 18 without court documents. So call up but I would go down to the vital Statistics office for your state (this will be the in the state capital in most cases) and ask for change of name papers and fill them out and ask when you can get his birth certificate with the new name on it. Since you both aren't married and you both aren't together I would talk with her cause If I am right both of you have to sign the papers for this. She could also stop you from doing this as well.





Good Luck
Reply:unfortunately for you the father with paternity papers or not has no say in the child's name! it was a thank god for me....you can not change his name with out the mother there to sign and you should probably know that most states will not let you fight her for that because if you are not married the baby is supposed to have her last name!
Reply:u see if the mom is willing to give up her rights if she is then u have to go up to the court house and change it there.i should kno i had to do it to my step daughter.oh yea the son cant see his mom any more.

Reply:Ok, we LEGALLY changed my oldest daughter's last name to that of her step-dad. Her bio dad was on her birth certificate and you CAN legally change the last name. You have to go down to your county courthouse and find out of they have specific forms for it. You have to file a petition to change the name, pay for an annoucement to be run in the paper notifying anyone and everyone of the name change, and then go to court for the decree of name change. You can file it all on your own, I think it cost us $110 here in OK.





You can also contact a paralegal about it and have them do the paperwork or you can have an attorney do it. I'm pretty sure the laws are natiowide on this one, though I could be wrong. You can even find places online that will process all of the documents for you, all you do is enter all of the information, they print them and send them to you for you to file. It costs money to do it that way though.
Reply:you might want to call the probate court in your town and ask them what you need to do. In my state you would go to probate court.
