Ok guys, if you claim that she "trapped" you into getting pregnant and you should therefore not be ordered to pay child support, it won't work in Texas.
The State of Texas legislature has determined that you voluntarily "participated" so therefore you are responsible for the "fruits" of your labor -- the kid.
If it's your DNA, it's your responsibility.
ALWAYS, ASK FOR DNA TESTING WHEN A BABY IS BORN!
EVEN IF YOU ARE MARRIED TO THE MOM!
