My ex wife has remarried and she and her spouse want me to waive and sign my parental rights away so he can legally adopt my two daughters. I am being told in the state of North Carolina I would still be responsible for all back support owed as well as possibly continued payments.
Hope to find out what the exact truth is

You would not be liable for any future payments. The past payments is a debt, I would get an attorney to review all the paper work before I signed it

No you would not be subject to continued support. When a person adopts they become the legal parent and assume responsibility for the child.

However, you would be responsible the arrears. However, your wife may be able to waive the requirement to pay the arrears.

(DO NOT) sign your parental rights away, no matter the reason, your children in the future will think that there (DAD) did not want anything to do with them, and it will damage them in ways that are not reversible, I know this because, my mother, is one of the lead investigaters of the hit Tv show the (Locater) on we Tv her name is (Susan friel williams) go to (we Tv-locater) and chek it out and it will give you some insight about what you are planning to do!!

First, this is the Family LAW forum. Answers here need to deal with the legal questions asked and conform to existing law. The OP asked about the effect relinquishing rights would have on future child support and arrears. Therefore your response was inappropriate.

Second, Sorry, but what you say is not a given. You don't know what the OP's current relationship is with his ex, her husband or his kids. It may be that he has already alientated his kids to the point that the relationship is already dead. Or, he may have a very good relationship and the ex will not interfere with that even if he does give up his rights. By your logic, a mother giving her child up for adoption is saying she doesn't love the child, when, instead, giving a child up for adoption may be the ultimate expression of love.

This is the second time I've seen you post something where your black and white answer ignores that there may be various shades of gray that mitigate your answer. Please be more careful about that in the future.
