FORMULA How Indiana Calculates Child Support
Indiana Code Section 31-16-6-1 governs child support. Indiana uses published weekly income schedule tables. Support ends at 19 but courts can order educational support through 21 for college-bound children.
AGE When Does Child Support End in Indiana?
Child support in Indiana ends when the child turns 19 — Indiana support ends at 19 (courts may extend to 21 for college). 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 Indiana
Indiana charges 8% annual interest on unpaid child support arrears. There is generally no statute of limitations on child support debt.
ENFORCEMENT Indiana Child Support Enforcement
Indiana 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 Indiana
Child support can be modified in Indiana 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.
