My sons mother has been keeping my son away from me for almost a year now. Hes 8 years old and he looks nothing like me. Im beginning to think that he may not even be mine. Any time I try to see him she calls the police and has me arrested by saying I hit her. She has put a protective order on me and now I can't even get visitations. There has to be a reason why she has been doing this. Maybe he isn't mine and this is the only way she can still get child support by keeping him away from me and making me look bad through the courts. How can I get a court order DNA test in the state of Connecticut for my 8 year old son..

I would see about speaking with a family law attorney, or a legal aid counsel, to discuss what your options are.

Here is a starting place:

Connecticut Paternity Testing

First, I'm assuming you aren't married. Second, why wasn't a paternity test done when the child support order was first issued (I'm assuming you are paying support as a result of a court order). If you accepted paternity at the time of birth it may be too late to challenge it.

In any case, for a court to accept it and change the support order it needs to be ordered by the court. So the bottom line is that you consult a family law attorney who can tell you whether you should bother requesting a test and how to go about it.

Also what actions have you taken to enforce visitation?

Or Paternity acknowledgment;)
Sec. 46b-172. (Formerly Sec. 52-442a). Acknowledgment of paternity and agreement to support; judgment. Review of acknowledgment of paternity. (a)(1) In lieu of or in conclusion of proceedings under section 46b-160, a written acknowledgment of paternity executed and sworn to by the putative father of the child when accompanied by (A) an attested waiver of the right to a blood test, the right to a trial and the right to an attorney, and (B) a written affirmation of paternity executed and sworn to by the mother of the child shall have the same force and effect as a judgment of the Superior Court. It shall be considered a legal finding of paternity without requiring or permitting judicial ratification,

(2) The mother and the acknowledged father shall have the right to rescind such affirmation or acknowledgment in writing within the earlier of (A) sixty days, or (B) the date of an agreement to support such child approved in accordance with subsection (b) of this section or an order of support for such child entered in a proceeding under subsection (c) of this section. An acknowledgment executed in accordance with subdivision (1) of this subsection may be challenged in court or before a family support magistrate after the rescission period only on the basis of fraud, duress or material mistake of fact which may include evidence that he is not the father, with the burden of proof upon the challenger. During the pendency of any such challenge, any responsibilities arising from such acknowledgment shall continue except for good cause shown.
