My husband is thinking about having DNA done on his youngest child 6ys. He has signed the B/C. He was told by another man that even if the child turns out not to be his he can fight to keep the child proofing that she is unfit. Is this true?

Where?

Do I have this right? Your husband wants custody of the 6-year old child, regardless of whether the child is his? Has DNA been done?

Was he married to the mother? Was she married to someone else?

So much depends on where you are at, if he requests a DNA test though the court it is to change or modify some current court order. In some states once he proves in court he is not the father, he will have no further legal ties, in others he only has a number of years to contest, in some he can not even contest.

But if he wants to keep the child or get custody of the child, why would he be asking for a DNA test to prove he is not the father, you do one or the other, not both
