When does child support end in Texas?
Texas law sets when support ends (generally age 18 with high school enrollment rules). See Texas Family Code provisions linked from OAG materials and the statute reference on this page. Courts and orders can differ.
How does the OAG handle unmarried parents and paternity?
The OAG provides paternity and case-opening resources for unmarried parents on texasattorneygeneral.gov, including acknowledgement of paternity and court-ordered testing. Paternity affects support establishment but is not legal advice on this site.
How are net resources calculated for self-employed parents?
OAG tax charts and self-employment guidance explain net resources for wage earners and self-employed income. Use OAG publications and the official calculator rather than guessing deductions on third-party sites.

Guideline percentages apply to monthly net resources up to $11,700 (cap effective 2025-09-01, per OAG revised tax charts). Income above the cap may still affect orders under Family Code §154.126.
