Can she change my daughters name?

What is the name of your state? New York
Some background on me here would be helpful. I am a 36 yr.old male who fathered a child 8 years ago. I contested paternity and failed one of the 3 criteria used in the blood test for paternity, that test excluded me from being the father. The mother of the child convinced me that mistakes were possible, and over the years her resemblance to me is obvious. My name never went on th BC but I am the only father she has known. I have religiously paid CS for close to 8 yrs. now. We live in the same town and we see each other a couple times a week. It has been an amiable relationship with the bio mom, up til now.
Bio mom is going to marry a man and wants to give our child his last name, (she now has her mom's last name), she even casually mentioned adoption. This floored me and I need to know if she can do this without my consent. AND, is there any way she can change the childs name without having her new husband adopt her? I realize that my first step will be to establish paternity. Any advice would be greatly appreciated. Petah

Without prove of paternity and/or your name on the birth certificate, you have no rights to the child. Obviously, you also have no obligation to support the child.

So, without any rights, the mother is free to change the childs name with or without your permission.

now wait a minute Jetx..... this is totally reverse from what we were told,************** my son in law has paid support for his child for 7 years, there were no test proving or disproving his paternity.... but he has paid, and they tell him cause he's paid for two years the SOL for him to fight custody is out... so why is this difference?? seems if the child and the father claim each other he should be the father by default... just like my son in law... does the SOL(statute of limitations) not work in a reverse situation?? or seems the mother would need to reinburse him for monies paid for a child that is not his,..... either way... I cant see her getting her cake and eating it too...

I appreciate your replies. It's obvious that I need to get the test done to establish paternity. In my heart (and head) I know I am this childs father. For years and years I have let her mom call all the shots. From when she was available for a visit, to how much money she needed etc.. I have tried to convince myself that it's just a name, but I can't swallow my daughter being given another man's name. I've been a stand up guy all these years and that should count for something in the eyes of the law.
