How to Sue an LLC or Business in Small Claims Court in Pennsylvania

Why Naming the Entity Correctly Matters

Filing against the wrong name is one of the most common mistakes in Pennsylvania small claims. If you sue "Mike's Plumbing" but the legal entity is "MPM Plumbing Services LLC," your judgment may be unenforceable — the person or entity you named may not technically owe anything, and the actual debtor was never a party to the case.

Getting the name right at the filing stage takes a few minutes of research and prevents weeks of wasted effort.

DBA vs. LLC vs. Corporation

A DBA (doing business as) is a trade name, not a legal entity. The actual defendant is the person or company behind it. If a sole proprietor operates under a trade name, you name them as "Jane Smith d/b/a Smith Quality Painting." If an LLC uses a trade name, you name the LLC itself.

An LLC (limited liability company) is a separate legal entity. You sue the LLC, not the individual members, unless you have grounds to argue they should be personally liable. The complaint names the entity exactly as it is registered: "Smith Quality Painting LLC" — not "Smith Quality Painting" and not "Smith Quality Painting, LLC" with a comma if the registration has no comma.

A corporation follows the same logic. Name it with the exact designation on file: "Inc.," "Corp.," or "Corporation."

Search the Pennsylvania Department of State

Go to the Pennsylvania Department of State Business Entity Search at corporations.pa.gov. Search by business name, and the database returns:

• The exact legal entity name and designation
• Whether the entity is active, inactive, or dissolved
• The registered office address
• The name and address of the registered agent (the person or service designated to accept legal papers on behalf of the entity)
• Any fictitious names (DBAs) registered to the entity

If the business operates under a fictitious name, the database shows the underlying entity. If you cannot find the business at all, it may be an unregistered sole proprietorship — in that case, you are suing the individual owner.

Service on Business Entities

Under Pa.R.C.P.M.D.J. Rule 310, service on an LLC or corporation may be made on an executive officer; an agent or person in charge at an office or usual place of business; or an agent appointed to receive service. Certified mail to the entity's regular place of business is also permitted when the return receipt shows the entity received it. A registered agent is one authorized recipient; confirm the correct address and service method with the court.

If the registered agent address is outdated and service fails, you may need to search for the entity's current principal office or the individual officers. An annual report filing with the Department of State sometimes lists a more current address.

For sole proprietors, service goes to the individual's home or business address — not a PO Box.

Who Shows Up in Court

Under Pa.R.C.P.M.D.J. Rule 207, an LLC or corporation does not need to send a lawyer to a Magisterial District Court hearing. A corporate officer or a full-time employee with direct personal knowledge of the dispute can represent the entity, but they must file a written Authorization of Representative form (AOPC 317 / MDJS 317-BL) before the hearing.

In Philadelphia Municipal Court, the entity must use PMC Form 03-127W if a non-officer employee is appearing.

If the business fails to send anyone to the hearing, you can request a default judgment — but you still need to present evidence and testimony proving your claim amount.
