A family lawyer in Brownsville Texas often deals with challenges to paternity. The Texas Family Code establishes rules for the use of Genetic testing to establish paternity or to contest paternity. If you desire a DNA test to help you in a child custody or child support matter, then I advise you to consult a Family Lawyer before you proceed.
There are time limits that apply to certain paternity challenges. Do not wait if you believe that you are being made to pay child support for a child that is not yours.
