How to File a Counterclaim in Small Claims Court Pennsylvania

When someone sues you in Pennsylvania small claims court, you do not have to limit yourself to defense. If the plaintiff owes you money from the same dispute — an unfinished job, withheld deposit, or damaged property — you can file a counterclaim and let the judge sort out both sides at the same hearing.

What a Counterclaim Is

A counterclaim is your own lawsuit against the plaintiff, filed within the existing case. Under Pa.R.C.P.M.D.J. Rule 315, you can assert any claim against the plaintiff that is within the Magisterial District Court's jurisdiction; it does not have to arise from the same transaction or be the same type of claim. A contractor sues you for $5,000 in unpaid work, and you believe they caused $3,000 in damage to your property — that qualifies. An unrelated debt the plaintiff owes you from a separate deal can qualify too if it is within the court's jurisdiction.

How to File

You fill out a standard Civil Complaint form (AOPC 310A) — the same form used to start a new case — with your claim against the plaintiff. You file it with the same Magisterial District Court that is handling the original complaint.

The deadline: Your counterclaim must be filed at least five days before the scheduled hearing date. Miss that deadline, and the court will not hear your counterclaim at this hearing — though you could potentially file a separate case later.

Filing fee: Rule 315's official note says there is no filing fee for a cross-complaint.

Service: Rule 315 applies the regular complaint service rules to your cross-complaint. It is served by the sheriff or a certified constable, or by certified mail when permitted. The court sets a consolidated hearing for both claims 12 to 30 days after filing and notifies the parties.

The $12,000 Cap Applies to Counterclaims Too

Your counterclaim cannot exceed the $12,000 jurisdictional limit (exclusive of interest and costs). If your damages are higher, you can waive the excess to stay in small claims court, or file a separate action in the Court of Common Pleas.

How the Judge Decides

At the hearing, the judge hears both the original claim and your counterclaim. If the plaintiff proves they are owed $5,000 and you prove you are owed $3,000, the judge enters a net judgment — in this case, $2,000 in the plaintiff's favor. If your counterclaim exceeds the plaintiff's claim, the net judgment goes in your favor.

Counterclaim vs. Separate Lawsuit

Filing a counterclaim within the existing case is almost always better than starting a new one. Both sides present everything at once, the judge sees the full picture, and you avoid paying separate filing fees and attending a second hearing.

The one exception: a claim outside the Magisterial District Court's jurisdiction cannot be filed as a cross-complaint under Rule 315 and must be brought in a court with jurisdiction.
