Child Support Past 18 in Tennessee: High School Graduation and Age Limits
In Tennessee, child support runs to 18, or to graduation or the class’s graduation for a child who turns 18 in high school, whichever is last. In state-enforced cases it does not continue past 19 except for a disabled child.
What is the child support age limit in Tennessee?
Eighteen, or later for a child still in high school. For the guidelines, a child is a person, not otherwise emancipated, who is under 18, or who reaches 18 while in high school until graduation or until the class of which the person was a member at 18 graduates, whichever occurs last (Tenn. Comp. R. & Regs. 1240-02-04).
How is the end date worked out?
The later of the 18th birthday and the end of the expected graduation month.
| Child born (class graduating in June of the year they turn 18) | Turns 18 | Support runs to | Turns 19 |
|---|---|---|---|
| March 15, 2012 | March 15, 2030 | June 30, 2030 | March 15, 2031 |
| August 31, 2011 | August 31, 2029 | August 31, 2029 | August 31, 2030 |
| November 2, 2015 | November 2, 2033 | November 2, 2033 | November 2, 2034 |

What does the class graduation rule mean?
The guidelines extend support to the later of the child’s own graduation or the graduation of the class the child belonged to at 18, so a child who graduates early or late is measured against the class date. Ask the school for the class graduation date.
Is there a Tennessee 19-year limit?
In Title IV-D cases, an obligor may seek termination when the child has reached 18 and has graduated, or the child’s class has, but the statute says in no event shall support continue after the child reaches 19 except as provided for disabled children (Tenn. Code 36-5-101(g)(6)(B)). For orders outside the state program, read your order.
What notice does the Tennessee state agency send?
In cases the Department of Human Services enforces, it must give the obligor notice 90 days before a child’s 18th birthday, as shown by its records (36-5-101(g)(6)(A)). Use it to line up your termination request.
What must be true to end a Tennessee order?
The department’s records, or your written documentation, show the child is 18 and graduated (or the class has) or has died or married; no other special circumstances, such as disability, require continuing; you owe no arrears to the obligee, the department or any other state; court costs are paid; and no other children are on the order (36-5-101(g)(6)(B)).
What if graduation is delayed?
If the child is still in high school at 18, support runs to graduation or the class’s graduation, whichever is last (1240-02-04). Update the court and the department when the date changes.
Do I need to file anything for the 18th birthday?
In a state case, wait for the department’s notice 90 days before the birthday and send proof of graduation; in other cases, ask the court to end the order. Do not stop paying on your own (36-5-101(g)(6)).
Do arrears end when child support ends?
No. Absent a court order to the contrary, withholding continues in the existing amount until arrears and costs are satisfied (36-5-101(f)(3)). See the Tennessee child support arrears calculator and how long arrears last.
