How child support ends in Pennsylvania

The end age, the college question, the disability track, and how support can end early.

How it worksWhat it means
The later of 18 or graduationUnder 23 Pa.C.S. §4321, parents must support an unemancipated child until 18 or high-school graduation, whichever is later.
Disabled adult childA parent may be required to support an adult child with a physical or mental condition that prevents self-support, recognized under §4321 and Pennsylvania case law, while the incapacity lasts.
Early emancipationMarriage, self-support, or a court finding of emancipation ends the duty early.
College and early endWhat it means
No court-ordered college (struck down)Pennsylvania does not allow a court to order a parent to pay for college. The post-secondary-support statute, §4327, was ruled unconstitutional in Curtis v. Kline (1995) for treating children of divorced parents differently from those of intact families. Earlier, Blue v. Blue (1992) held there is no common-law duty to pay for college.
Agreements still bindA college-contribution clause in a marital settlement or separation agreement is an enforceable contract even though a court could not impose the obligation.
Court-ordered college support
No. The post-secondary support statute was struck down in Curtis v. Kline, and there is no common-law duty (Blue v. Blue). A Pennsylvania court cannot order college support. Only a voluntary agreement binds a parent.

What you can do right now

Concrete, neutral steps around ending or extending child support in Pennsylvania. This is legal information, not legal advice.

  1. Count to the later of 18 or graduation

    Support continues until the child turns 18 or finishes high school, whichever is later. A child still in school at 18 keeps support until graduation.

  2. Do not expect court-ordered college support

    The college-support statute was struck down, and there is no common-law duty. Put any college arrangement in a written agreement instead.

  3. Address a disabled adult child separately

    A parent may be required to support an adult child with a condition that prevents self-support, while the incapacity lasts.

  4. Talk to a Pennsylvania family attorney

    Termination timing, disability support, and college agreements turn on your facts. A licensed Pennsylvania attorney can confirm your situation. The Bar can refer you to one.

What people get wrong about child support ending in Pennsylvania

Pennsylvania ends child support at the later of 18 or high-school graduation, so a child still in school at 18 keeps support until they finish. The college question has a notable history here. Pennsylvania once had a statute, 23 Pa.C.S. §4327, that let courts order divorced parents to pay for college. The state Supreme Court struck it down in Curtis v. Kline in 1995 on equal-protection grounds, because it treated children of divorced parents differently from children of intact families, who have no such right. Three years earlier, Blue v. Blue had already held there was no common-law duty to pay for a child’s college. The two cases are often confused, but they play different roles: Curtis v. Kline voided the statute, and Blue v. Blue closed the common-law route. The upshot is that a Pennsylvania court cannot order college support at all; only a college-contribution clause in a settlement agreement, which is an enforceable contract, can bind a parent. Section 4327 still prints in the code, but it is unenforceable. A disabled adult child can be supported while the incapacity lasts.

Common questions

At what age does child support end in Pennsylvania?

At 18 or high-school graduation, whichever is later, under 23 Pa.C.S. §4321. A child still in high school at 18 keeps support until graduation.

Can a Pennsylvania court order a parent to pay for college?

No. The college-support statute (§4327) was struck down as unconstitutional in Curtis v. Kline, and Blue v. Blue held there is no common-law duty. Only a voluntary agreement can bind a parent.

Was it Blue v. Blue or Curtis v. Kline that ended college support in Pennsylvania?

Both, in different roles. Curtis v. Kline (1995) struck down the college-support statute, while Blue v. Blue (1992) held there is no common-law duty to pay for college. Together they mean no court-ordered college support.

Can Pennsylvania child support continue for a disabled adult child?

Yes. A parent may be required to support an adult child with a physical or mental condition that prevents self-support, while the incapacity lasts.
