How to Disestablish Paternity After Divorce

[KJames]

My question involves paternity law for the State of: New Hampshire

My ex-wife has a son who I thought was mine when she had him. Turns out, he is not mine. I never suspected until my current girlfriend asked about his eye color. Turns out, she was right, kid is not mine. I have very limited contact with the child and no real connection with him as he is autistic and does not really make emotional connections. His mother left the house when he was about 3 months old and the reason for divorce is "abandonment" on her part.

Can I still disestablish paternity and stop paying child support? What is the age limitation. I have contacted a lawyer, but he cannot see me until next Friday and I am too anxious to wait until then to know.

How old is the child?

How did you determine that the child is not biologically yours?

He is almost 4. I did an online DNA test, it came up with a 0% chance at me being the father and then we went and did a DNA test at a doctor's office/center which is considered to be legally acceptable- same result.

It won't be legally acceptable.

The court will need to order a DNA test.

How long have you been divorced?

[KJames]

I will be divorced one year in October.

From what I've seen so far, the courts of your state (like most others) don't seem particularly receptive to post-divorce efforts of a father to delegitimize a child. See, e.g., Watts v Watts, 115 N.H. 186 (1975); McRae v McRae, 115 N.H. 353 (1975). I suggest consulting a family lawyer.
