⚖ 50/50 Custody in Texas
Does Child Support Apply With 50/50 Custody in Texas?
In most cases, yes. Texas does not automatically eliminate child support with equal parenting time.
✓General rule: With 50/50 custody, the higher-earning parent typically pays the lower-earning parent. The amount is reduced vs sole custody but rarely reaches $0.

FORMULA How Texas Calculates Child Support

Texas Family Code Section 154.125 governs child support guidelines. Texas updated its Standard Possession Order in 2021-2023 to make 50/50 parenting time more accessible. The income cap is periodically updated.

AGE When Does Child Support End in Texas?

Child support in Texas ends when the child turns 18 — or high school graduation, whichever is later. Support also ends upon the child’s death, marriage or emancipation. Important: In most cases support does not stop automatically — you need a court order. Stopping payments without a court order creates arrears even after the child reaches the cutoff age.

INTEREST Arrears Interest in Texas

Texas charges 6% annual interest on unpaid child support arrears. There is generally no statute of limitations on child support debt.

ENFORCEMENT Texas Child Support Enforcement

Texas has broad enforcement powers including wage garnishment, tax refund interception, driver’s license suspension, professional license suspension, passport denial, and credit bureau reporting. Criminal charges may apply for significant or long-term non-payment.

MODIFY Modifying Child Support in Texas

Child support can be modified in Texas when there is a material and substantial change in circumstances — typically a significant income change, job loss, new children from another relationship, or change in custody. Most states also allow a periodic review every 3 years. File a petition with the court — private agreements to change support are not legally enforceable.
