Blended families are common, and so is this question. You helped raise your partner's child for years. The relationship ended. Can you be ordered to pay child support?

The general rule: parents owe support

In Pennsylvania the duty to support a child belongs to the child's parents. That means biological and adoptive parents. A stepparent does not take on a legal support duty by marrying a parent, and that duty does not arise because a stepparent was generous during the marriage.

The Supreme Court's 2024 decision

The Pennsylvania Supreme Court addressed the edge of that rule in Caldwell v. Jaurigue, 315 A.3d 1258 (Pa. 2024).

A mother's former boyfriend had helped raise her child and stood "in loco parentis," the legal term for a person who has taken on a parent's role. After the mother died, he obtained some custody time. The child's father then sought child support from him.

The Supreme Court held that he was not a "parent" obligated to pay child support. He had acted as a parent and had custody time, but he did not have legal custody of the child. Without that, the support obligation did not attach.

The exception: when a non-parent seeks full parental rights

Pennsylvania courts have ordered support from a non-parent in rare cases. The best known is A.S. v. I.S., 130 A.3d 763 (Pa. 2015). There a stepfather went to court and fought for the same custody rights as a biological parent, including blocking the mother from relocating. The Supreme Court held that having claimed a parent's rights, he took on a parent's obligations.

Read together, the cases draw a line. Love, time and money given to a child do not create a support duty. Going to court to obtain the full legal rights of a parent can.

What this means in practice

• Stepparents after a divorce. You generally do not owe support for a stepchild. Think carefully, with advice, before filing for shared legal custody.
• Parents. You usually cannot collect support from a former partner who is not the child's parent. Your claim is against the other legal parent.
• Grandparents and other caregivers. If you are raising a child, you may be able to seek support from the parents.
• Adoption changes everything. A stepparent who adopts is a legal parent with a full support obligation.

Frequently asked questions

Do stepparents have to pay child support in Pennsylvania? Generally no. The support duty belongs to the child's legal parents.

Can my ex-boyfriend or ex-girlfriend be ordered to support my child? Not unless he or she is the child's legal parent or, in rare cases, has gone to court and obtained the rights of a parent. See Caldwell v. Jaurigue (Pa. 2024).

What does in loco parentis mean? It describes a person who has taken on the role and duties of a parent with the parent's consent. It can give that person standing to seek custody.

If I seek custody of my stepchild, will I owe support? It depends on what you seek. Asking for visits is different from asking for the full legal rights of a parent. Get advice before you file.
