Who Can File for Custody in Pennsylvania

Not just anyone can walk into a Pennsylvania courthouse and file for custody of someone else's child. The law requires "standing" — a legal basis that gives you the right to bring the case. Pennsylvania's standing rules expanded dramatically in 2018, but they still have specific requirements depending on who you are and what custody you are seeking.

Standing for Full Custody (23 Pa.C.S. § 5324)

Under § 5324, four categories of people can file for any form of physical or legal custody:

Parents (§ 5324(1)) — Biological and adoptive parents always have standing.

In loco parentis (§ 5324(2)) — A non-parent who has assumed parental status with the consent of the natural parents. This means you have been acting as the child's parent in a meaningful, sustained way: providing daily care, making decisions about schooling and health, maintaining the child in your home. Casual babysitting does not count. Neither does a brief stay or informal arrangement where the parent remained actively involved in daily decisions.

The critical element is parental consent. If a parent placed the child with you voluntarily — even informally — and you have been functioning as the parent, you likely have in loco parentis standing. If the parent never consented and you took the child unilaterally, this category does not apply.

Grandparents with a qualifying relationship (§ 5324(3)) — A grandparent or great-grandparent whose relationship with the child began through parental consent or a court order, and one of these conditions exists: the child has been adjudicated dependent, the child is at risk, or the child lived with the grandparent for 12 or more months.

Act 21 third-party standing (§ 5324(4)) — Enacted in 2018, this is the broadest category. Any third party — aunt, uncle, cousin, sibling, family friend, stepparent — can file if all three requirements are met:

1. The child is not in the care and control of a parent
2. The third party has assumed responsibility for the child in loco parentis or has a substantial, ongoing relationship with the child
3. The parents have failed or refused to perform parental duties, or the child has been adjudicated dependent by a court

This provision filled a gap that left many relatives unable to file before 2018. An aunt who has been raising her nephew for two years after both parents went to prison now has a clear statutory path.

Standing for Partial Custody (23 Pa.C.S. § 5325)

Partial custody is visitation time — not full care. Only grandparents and great-grandparents can file under § 5325, in three specific situations:

Deceased parent (§ 5325(1)) — You are the grandparent on the side of the parent who died. You can seek scheduled visitation with your grandchild.

Active custody action with parental disagreement (§ 5325(2)) — The parents already have a custody case between them, and they disagree about whether you should have access to the child. This section was rewritten by Act 169 of 2018 after the old version — which gave grandparents automatic standing whenever parents were separated for six months — was struck down as unconstitutional in D.P. v. G.J.P. (2016).

12-month co-residence (§ 5325(3)) — Your grandchild lived with you for at least 12 consecutive months and was then removed by the parents. You must file within six months of the removal.

Who Cannot File

• A family friend or neighbor who has not assumed parental duties — emotional bonds alone do not create standing
• A relative who wants custody but whose situation does not fit any of the four § 5324 categories
• A person filing in a county without proper venue. Custody venue is ordinarily in the county where the child has established permanent residence.
• A person who took a child without parental consent does not establish standing through that act alone; another statutory category must apply.

Proving Standing

Standing is evaluated at the beginning of the case. The opposing party (usually a parent) can file a preliminary objection challenging your standing, and the judge will hold a hearing on standing alone before the case moves forward.

To prove standing, you need evidence:

• For in loco parentis: Documentation of your caregiving — school records listing you as a contact, medical appointment records, photographs, testimony from teachers or neighbors, communication with the parent showing consent
• For Act 21: Evidence that the child is not in parental care, evidence of your relationship with the child, and evidence that parents failed their duties (CYS records, police reports, testimony)
• For the 12-month residence categories: Proof of the child's address history — utility bills, lease documents, school enrollment records showing your address

A parent can defeat your standing claim by showing they never consented to you acting as a parent, that they maintained active parental involvement, or that the statutory conditions you claim do not actually exist. This is why documentation matters from the day a child comes into your care.

The Practical Reality for Aunts, Uncles, and Non-Grandparent Relatives

Before Act 21 of 2018, aunts, uncles, and cousins had an extremely difficult time establishing standing unless they could prove in loco parentis. Act 21 changed that by creating a broader category that does not require the traditional in loco parentis analysis — if the child is not in parental care and you have a substantial relationship, you can file.

However, "substantial relationship" is not defined by statute, which means the judge has discretion. Courts generally look for a meaningful, ongoing connection: regular involvement in the child's life, caregiving history, and the child's attachment to you.
