Is there a Statute of Limitations Concerning Money Judgment for Child Support?

Yes.
The court of continuing, exclusive jurisdiction retains jurisdiction to confirm the total amount of child support arrearages and enter judgment for past-due child support. The statute of limitations concerning a money judgment is ten years. The suit must be filed within ten years from the date the child becomes an adult, or the child support obligation terminates. (157.005(b)).

I've Been Sued for Not Paying Child Support, But My Child Has Been Living With Me. Can I Argue This In My Defense?

Yes you can. If the order is for your child to live with the other party, but your child has lived with you partially, you may be entitled to an offset of the child support obligation. If the child has lived with you full time, you may be entitled to a complete discharge.

If the managing conservator has voluntarily relinquished to the obligor the actual care, control and possession of the child for a time period in excess of court-ordered possession or access, the obligor may affirmatively plead and prove that actual support, if any which was supplied to the child. The court may treat this proof as a defense and offset, in whole or in part, to a motion for contempt for failure of the obligor to make periodic support payments according to the terms of the order (157.008).
