How to File for Custody as a Grandparent in Pennsylvania

You have been raising your grandchild for months — maybe longer — and now a school, a doctor's office, or a benefits agency is asking for legal documentation you do not have. Filing for custody in Pennsylvania is not as overwhelming as it looks once you understand the sequence.

Confirm You Have Standing First

Pennsylvania does not let just anyone file a custody complaint for a child who is not theirs. Before you walk into the Prothonotary's office, you need to know which standing category applies to you under Title 23.

Grandparent primary custody (§ 5324(3)) requires that the relationship began with parental consent or court order and that the child is dependent, at risk, or has lived with you for at least 12 months.

In loco parentis (§ 5324(2)) applies when a parent consented to you assuming full parental responsibilities — feeding, clothing, schooling, medical care — and you have been carrying those duties consistently. Casual babysitting does not count.

Act 21 third-party standing (§ 5324(4)) covers aunts, uncles, siblings, or family friends who can show the child is not in parental care and the third party has a substantial relationship with the child.

If your situation does not clearly fit one of these categories, you will need legal advice before filing. Filing without standing wastes your filing fee and delays protection for the child.

Gather Your Paperwork

Pennsylvania custody complaints go through the Court of Common Pleas — specifically the Family Division (or Civil Division in counties without a separate Family Division). You will need:

• Custody Complaint (Form 2) — this is the statewide form specifically for grandparents and third parties, different from Form 1 used by parents
• Criminal Record and Abuse History Verification (Form 3) — each party files a sworn disclosure of their own history and the history of adult household members under Pa.R.C.P. 1915.3-2 / 1915.15(c)
• Confidential Information Form (CIF) and Confidential Document Form (CDF) — these protect sensitive data like Social Security numbers from the public docket
• In Forma Pauperis petition — if you cannot afford the filing fee (typically $135–$410 depending on the county), this requests a fee waiver

Some counties require additional local forms. Philadelphia uses a Family Court Cover Sheet and Custody Intake Questionnaire. Allegheny County requires Kayden's Law Verification forms. Rural counties may have their own cover sheets. Call your county's Prothonotary or check the UJS portal at pacourts.us before you go.

File at the Prothonotary

Bring the original complaint plus the number of copies your county requires — usually two to four (one per party being served). In most counties you file in person at the Prothonotary's office. Philadelphia and Allegheny County offer electronic filing for attorneys, but pro se filers can still file on paper.

The intake clerk checks your paperwork for completeness: correct caption, signatures, mandatory verification forms attached, and either a fee payment or IFP petition. The clerk does not evaluate whether you have valid standing — that is a legal question for the judge.

Once filed, you receive a docket number and time-stamped copies. Keep these carefully. Your docket number is how you track your case on the UJS Web Portal.

Serve the Other Parties

After filing, you must serve every person who holds parental rights. Pennsylvania allows three methods under Pa.R.C.P. 412:

1. County Sheriff
2. Certified mail with return receipt, restricted delivery
3. Personal service by a competent adult who is not a party to the case

You have 30 days to complete service if the parent lives in Pennsylvania, or 90 days for an out-of-state parent. After service, file your Affidavit of Service with the Prothonotary — no hearing can proceed without proof of service on the record.

If a parent cannot be located after a genuine search effort, you can file a Motion for Alternative Service under Pa.R.C.P. 430, asking the court to approve service by publication. This is one area where consulting a lawyer or legal aid attorney is strongly recommended.

What Happens After Filing

Once service is complete, your county's scheduling process kicks in. Most counties send the case to a conciliation conference first, where a custody conference officer tries to help the parties reach an agreement. If no agreement is reached, the case moves toward mediation or a custody trial before a Common Pleas judge.

At every stage, the court evaluates the 14 statutory best-interest factors under 23 Pa.C.S. § 5328, with substantial weighted consideration given to child safety factors under Kayden's Law (Act 8 of 2024).

Frequently Asked Questions

Can a grandparent file for full custody in Pennsylvania?

Yes. Grandparents can file for any form of custody — including sole legal and sole physical custody — if they meet one of the standing categories under 23 Pa.C.S. § 5324. A § 5324(3) claim requires that the relationship began with parental consent or court order and that the child is dependent, at risk, or has lived with you for at least 12 months.

How much does it cost to file for custody in Pennsylvania?

Filing fees range from roughly $135 to over $410 depending on the county. If you are on a fixed income or receive public assistance, you can file a Petition to Proceed In Forma Pauperis under Pa.R.C.P. 240 to request a fee waiver.

Do I need a lawyer to file for custody as a grandparent?

No. Pennsylvania allows self-represented (pro se) filing, and the UJS provides free statewide forms. However, contested cases — especially those involving missing parents, abuse allegations, or interstate issues — benefit significantly from legal counsel. Legal aid organizations like Neighborhood Legal Services and Philadelphia Legal Assistance offer free help to qualifying individuals.
