I recently found that I was the father of an illegitament child and the mother and I agreed that it was best to terminate my parental rights. We have done that with the help of an attorney. I was the fourth person the mother accused of being the father of this child. There was a man before me who assumed he was the father and was ordered to pay child support for the past 2 years, but later discovered through dna testing that he was not the father. There was never any order by any governing agency for me to pay child support before the termination was ordered. Will I be responsible for any previous child support payments made to the mother?

There was no legal order for you to pay child support, so no.

How could you get rights terminated when you never had them in the first place? I think you got rooked somewhere. If this woman claimed you were the father, then you should have demanded they pay for a DNA test to prove it. Only then would you have had any rights. Until your paternity was proven you had no rights or responsibility to terminate.

So I'm not sure what you think was done, but I doubt if it was a TPR.

If a DNA test proved you were the father, then and only then could the mother have asked for support and is unlikely to have been granted back support.
