Child Support Past 18 in Kentucky: High School Graduation and Age Limits
In Kentucky, child support ends at emancipation, usually 18. A child who is a high school student at 18 stays covered while a student, but not beyond the end of the school year in which the child turns 19; marriage ends it.
What is the child support age limit in Kentucky?
Eighteen in most cases. Unless otherwise agreed in writing or expressly provided in the decree, provisions for the support of a child are terminated by emancipation of the child unless the child is a high school student when he or she reaches 18 (KRS 403.213(3)).
What if the child is still in high school at 18?
Where the child becomes emancipated because of age, but not due to marriage, while still a high school student, the court-ordered support continues while the child is a high school student, but not beyond completion of the school year during which the child reaches 19 (403.213(3)). The end is a school year, not a birthday, so the date depends on the school calendar.
| Child born | Turns 18 | Outer limit for a high school student |
|---|---|---|
| March 15, 2012 | March 15, 2030 | School year ending in 2031 (19th birthday March 15, 2031) |
| August 31, 2011 | August 31, 2029 | School year ending in 2031 (19th birthday August 31, 2030) |
| November 2, 2015 | November 2, 2033 | School year ending in 2035 (19th birthday November 2, 2034) |
What if the Kentucky child marries?
The extension is for a child emancipated because of age, not marriage, so a child who marries while a student is emancipated and support terminates unless the decree says otherwise.
Can the decree or an agreement change this?
Yes. The rule applies unless otherwise agreed in writing or expressly provided in the decree. Read your decree for an end date or event. If it needs changing, file a motion to modify.
Do I have to file to end child support?
The statute sets the end events, but income withholding keeps running until it is stopped. Ask the court or the Division of Child Support to end it in writing and keep proof of the child’s birth date and graduation. See how to modify child support in Kentucky.
How do I use the Kentucky child support end date calculator?
Enter the birth date and answer the two questions. The Kentucky child support end date calculator shows the 18th birthday, and for a high school student the school year in which the child turns 19. If your decree sets a different date, use that one.
What does the guidelines statute say about the amount after 18?
The guidelines set the amount for children the order covers; they do not add an age (KRS 403.212). The end date comes from the decree and the emancipation rule, so read both.
What should you gather before the child turns 18?
The birth certificate, the decree, a current school letter showing the child is a high school student and the expected completion date, and your payment history. Send the school letter to the other parent or the Division before the 18th birthday if you want support to continue.
Do arrears end when child support ends?
No. Emancipation does not terminate the obligation of child support arrearages that accrued while the child was an unemancipated minor (403.213(3)). See the Kentucky child support arrears calculator and how long arrears last.
