i know that one of the children of 2 that i am paying child support for is not mine. the state of texas is taking 119.23 out of each check every two weeks. i dont know how to prove that this child is not mine, since everything is said and done. i dont have the money for a lawyer is there any way to appeal it or something on my own. a blood test would prove the child is not mine. but my ex and the two kids live in texas and i live in colorado....what can i do?
