Child Support Past 18 in Pennsylvania: High School Graduation and Age Limits
In Pennsylvania, child support ends on the last to occur of the 18th birthday and high school graduation, and the court office sends an emancipation inquiry within six months before 18.
What is the child support age limit in Pennsylvania?
Eighteen, or high school graduation if later. Parents are liable for the support of unemancipated children who are 18 years of age or younger (23 Pa.C.S. 4321(2)), and the charging order ends on the last to occur of the date the last child reaches 18 or graduates from high school (Pa.R.C.P. 1910.19(e)).
What if the child is still in high school at 18?
The order continues until graduation. The calculator takes the end of the expected graduation month and compares it with the 18th birthday.
| Child born (graduating June of the year they turn 18) | Turns 18 | Order ends |
|---|---|---|
| March 15, 2012 | March 15, 2030 | June 30, 2030 |
| August 31, 2011 | August 31, 2029 | August 31, 2029 |
| November 2, 2015 | November 2, 2033 | November 2, 2033 |

What is the Pennsylvania emancipation inquiry?
Within six months before a child turns 18 the domestic relations section sends the obligee, with a copy to the obligor, a form asking for the child’s date of birth and graduation or withdrawal date, whether the child left the household, any agreement for payments after 18 or graduation, and any special needs (1910.19(e)). Return it within 30 days.
Who gets the inquiry, and what do I send?
The obligee gets it with a copy to the obligor. Send the child’s date of birth and graduation or withdrawal date, whether the child left the household, any agreement for payments after 18 or graduation and any special needs, with proof such as a diploma or school letter (1910.19(e)).
What if the child withdraws from high school before 18?
The inquiry asks for the date of graduation or withdrawal from high school. A withdrawal does not by itself end the order before the 18th birthday; the order ends on the last to occur of the two dates, so ask the section or court how it treats your case.
What if I do not return the Pennsylvania inquiry?
If no other children are on the order and the obligee does not return it within 30 days or asserts no ground to continue, the section administratively ends the charging order on the last to occur of the 18th birthday and graduation, without further proceedings. If other children are on the order or an agreement or special needs are claimed, it may schedule a conference first (1910.19(e)).
Does a child who leaves home before 18 lose Pennsylvania support?
The inquiry asks whether the child left the household, and an emancipated child cannot be supported by order (4323). Whether leaving makes a child emancipated is for the court; ask a licensed Pennsylvania attorney and file rather than stopping payment.
Does a written agreement matter?
Yes. The inquiry asks about any agreement requiring payments after 18 or graduation (1910.19(e)); a postsecondary agreement in a marital settlement agreement stays enforceable, and the court does not override its express terms (4327(i)).
What if the child turns 18 during the school year?
The order runs to graduation, so report the graduation date to the section and keep school records; the order ends on the later date if no ground to continue is asserted (1910.19(e)).
Do arrears end when child support ends?
No. Termination does not affect arrears accrued through the date, and the court can order payments equal to the charging order until all arrears are paid (1910.19(e)). See the Pennsylvania child support arrears calculator and how long arrears last.
