Aunt, Uncle, and Relative Custody Rights in Pennsylvania

Most of the information about kinship custody in Pennsylvania focuses on grandparents, because grandparents have their own dedicated standing categories under the law. But aunts, uncles, adult siblings, cousins, and even family friends are raising children across the state — and since 2018, Pennsylvania law gives them a clear path to legal custody.

Act 21 of 2018: The Standing That Changed Everything

Before Act 21, non-grandparent relatives had limited options. Unless you could prove in loco parentis status — that you had assumed full parental duties with parental consent — the courthouse door was effectively closed.

Act 21 created 23 Pa.C.S. § 5324(4), which grants standing to any third party who meets three conditions:

1. The child is not in the care and control of either parent — the parents are absent, incarcerated, in treatment, unable, or unwilling to care for the child
2. You have a substantial relationship with the child — or you have assumed responsibility for the child in loco parentis
3. The parents have failed or refused to perform parental duties, or the child has been adjudicated dependent

This is the standing category most aunts, uncles, and other non-grandparent relatives will use. It does not require 12 months of co-residence (one of the grandparent-specific grounds under § 5324(3)), and it does not require the parent's death (the § 5325(1) grandparent visitation category).

In Loco Parentis: The Alternative

If you have been functioning as the child's parent — providing housing, meals, school transportation, medical care, and emotional support — with the biological parent's knowledge and at least tacit consent, you may have standing under the in loco parentis doctrine (§ 5324(2)).

In loco parentis standing does not depend on biological relationship at all. A stepparent, a parent's long-term partner, or a family friend can establish it. What matters is whether you assumed comprehensive parental obligations and the parent permitted it.

The key distinction: in loco parentis requires parental consent to your role, while Act 21 does not necessarily require consent — it focuses on the parent's failure to perform duties.

The Filing Process

The process for non-grandparent relatives is the same as for grandparents:

1. File a Custody Complaint (Form 2) at the Court of Common Pleas in the county where the child lives
2. Attach Form 3 (Criminal Record and Abuse History Verification) for each party, disclosing their own history and the history of adult household members
3. Attach the Confidential Information Form and Confidential Document Form
4. Pay the filing fee or submit an In Forma Pauperis petition if you qualify
5. Serve every parent who has custodial rights within 30 days (in-state) or 90 days (out-of-state)

The difference from a grandparent's filing is in how you establish standing in the complaint. Under § 5324(3), grandparents must meet the parental-consent or court-order relationship condition and one of its statutory grounds, such as dependency, risk, or 12-month residence. Aunts and uncles typically cite § 5324(4) (Act 21) and detail the factual basis — the parent's absence, your relationship with the child, and the parental failure that brought the child into your care.

What the Court Considers

Once standing is established, the court applies the same 14 best-interest factors under 23 Pa.C.S. § 5328 that apply in any custody case. Your biological relationship to the child is not a statutory factor — what matters is:

• Which party is more likely to ensure the child's safety and daily needs
• The stability and continuity of the child's current living arrangement
• Each party's history of performing parental duties
• The child's relationship with you and the quality of that bond
• Any safety concerns under Kayden's Law (Act 8 of 2024)

Being an aunt, uncle, or sibling does not disadvantage you compared to a grandparent in the best-interest analysis. The court is evaluating the child's situation, not the filing party's title.

Common Challenges for Non-Grandparent Relatives

Standing disputes. Parents who contest your filing will likely challenge your standing first. Be prepared to document your substantial relationship with the child and the parent's failure to perform duties. School records showing you as the emergency contact, medical records showing your involvement, and communications with the parent can all support your standing claim.

Competing grandparent claims. In some families, an aunt or uncle files for custody while a grandparent also wants the child. Pennsylvania does not automatically prioritize grandparents over other relatives — the court evaluates each party's ability to serve the child's best interest.

Lack of awareness. Many non-grandparent relatives do not know they have standing under Act 21. If you have been told by anyone — including court staff — that "only parents and grandparents can file for custody," that information is outdated. Act 21 of 2018 specifically expanded standing to third parties with a substantial relationship.

Our Pennsylvania Guardianship and Custody Court Process Guide covers standing requirements for all relative categories and includes the same filing instructions whether you are a grandparent, aunt, uncle, or other caregiver.

Frequently Asked Questions

Can a family friend file for custody in Pennsylvania?

Yes, if they meet the Act 21 requirements under § 5324(4) — the child is not in a parent's care and control, the friend has a substantial relationship with the child, and the parents have failed or refused to perform parental duties or the child is dependent. The in loco parentis doctrine under § 5324(2) also applies to non-relatives who have assumed comprehensive parental responsibilities with parental consent.

Do aunts and uncles get the same custody rights as grandparents?

Once custody is granted, the order defines the rights awarded. The difference is in how standing is established — grandparents have additional standing categories under § 5324(3) and § 5325 that do not apply to other relatives. Under Act 21 (§ 5324(4)), a third party with a substantial relationship may seek any form of custody if the child is not in a parent's care and control and the parents have failed or refused parental duties or the child is dependent.

What if I have been caring for my niece or nephew informally for years?

Long-term informal care strengthens both your standing argument and your case on the merits. Document everything — how long the child has lived with you, the school they attend, their medical providers, the parent's absence or failure to provide. This evidence supports standing under both Act 21 and in loco parentis.
