Pennsylvania law is built in layers: the state constitution sits on top, the Pennsylvania Consolidated Statutes carry the bulk of the rules, state agencies fill in the operational detail through regulations in the Pennsylvania Code, and a four-level court system applies all of it. Because Pennsylvania is one of four states formally called a commonwealth, criminal cases are brought in the name of “the Commonwealth” rather than “the State,” and that wording appears in court names, filings, and citations throughout the system. The practical job for most people is narrower than understanding the whole structure: find the rule that applies, know which court handles the dispute, and file before the deadline runs out.
Where Pennsylvania Law Comes From
Every statute, regulation, and court ruling in Pennsylvania has to comply with the state constitution. If a statute conflicts with it, courts will strike the statute down. Article I, the Declaration of Rights, protects familiar freedoms and adds a few that go further than the federal Constitution: Section 21 says the right to bear arms “shall not be questioned,” and Section 27 establishes a constitutional right to clean air, pure water, and preservation of the environment, treating public natural resources as belonging to Pennsylvanians including future generations.1Pennsylvania General Assembly. Constitution of the Commonwealth of Pennsylvania
Consolidated Statutes
The main body of Pennsylvania law is the Pennsylvania Consolidated Statutes, cited as “Pa.C.S.” The General Assembly organized them by numbered title. A few you will see most often:
- Title 18 — Crimes Code
- Title 20 — Estates and trusts
- Title 23 — Domestic relations
- Title 42 — Judiciary and court procedures
- Title 75 — Vehicles and traffic
There are roughly 70 titles in all, covering everything from agriculture to zoning.2Pennsylvania General Assembly. Consolidated Statutes
Unconsolidated Statutes
Not every law has been folded into the consolidated system. Older statutes predating the 1970 consolidation effort, along with some specialized laws, remain “unconsolidated.” They carry the same legal weight but sit outside the modern numbering, which can make them harder to find. The General Assembly’s website hosts both sets.3Pennsylvania General Assembly. Statutes and the Constitution of Pennsylvania
Administrative Regulations
State agencies like the Department of Environmental Protection and the Department of Transportation write detailed regulations under authority delegated by the legislature. These rules fill in operational specifics statutes leave open and have the force of law. All current regulations live in the Pennsylvania Code, and proposed changes publish weekly in the Pennsylvania Bulletin.4Pennsylvania Code and Bulletin. About the Pennsylvania Code and Bulletin
If you are trying to figure out what the law requires for a specific activity, start with the consolidated statutes for the broad rule, then check the Pennsylvania Code for the agency-level details.
Which Court Handles Your Case
Pennsylvania’s Unified Judicial System has four tiers. Knowing which one hears your type of case determines where you file, what procedures apply, and where you appeal.
Magisterial District Courts and Municipal Courts
Magisterial District Courts are the entry point for most Pennsylvanians. They handle small claims up to $12,000 (not counting interest), preliminary hearings in criminal cases, landlord-tenant disputes, and summary offenses like traffic violations.5Unified Judicial System of Pennsylvania. Courts of Common Pleas Philadelphia and Pittsburgh use Municipal Courts for the same role within their city limits.
Courts of Common Pleas
When a case is too serious or too large for a minor court, it goes to the Court of Common Pleas. Pennsylvania has 60 judicial districts, generally following county lines. These courts handle major civil lawsuits, felony criminal trials, family law, and estate disputes, and for many matters this is both the first and last stop.5Unified Judicial System of Pennsylvania. Courts of Common Pleas
Superior Court vs. Commonwealth Court
Pennsylvania splits its intermediate appellate level into two courts, and the split confuses people constantly. The Superior Court hears appeals from the Courts of Common Pleas in criminal cases and private civil disputes. If you lose a personal injury trial or are convicted of a crime at the trial level, you appeal to the Superior Court.
The Commonwealth Court is the one you use when government is on the other side. It has original jurisdiction over lawsuits filed against the state government or its officers acting officially, and it hears appeals involving state and local government agencies.6Pennsylvania General Assembly. Pennsylvania Consolidated Statutes Title 42 Section 761 – Original Jurisdiction Challenging a regulatory ruling, disputing a tax assessment, or suing a state department all go to the Commonwealth Court.
Supreme Court of Pennsylvania
Established in 1722, the Supreme Court of Pennsylvania is the oldest appellate court in the nation.7Unified Judicial System of Pennsylvania.

Deadlines That Will Kill Your Case
Every legal claim in Pennsylvania has a filing deadline. Miss it and the court will almost certainly dismiss the case regardless of its merits.
Civil Deadlines
Personal injury claims — car accidents, slip-and-fall injuries, medical malpractice, assault, and wrongful death — must be filed within two years of the incident.9Pennsylvania General Assembly. Pennsylvania Consolidated Statutes Title 42 Section 5524 – Two Year Limitation Two years sounds generous until you factor in gathering medical records, identifying responsible parties, and negotiating with insurers. Negligence, fraud, and property damage claims also fall under the two-year window.
Contract claims get more time. Actions on a written contract must be filed within four years, as must claims on oral contracts, negotiable instruments, and contracts for the sale of goods.10Pennsylvania General Assembly. Pennsylvania Consolidated Statutes Title 42 Section 5525 – Four Year Limitation Identity theft claims also carry a four-year deadline, running from either the date of the offense or the date the victim discovered it, whichever is later.
Criminal Deadlines
For criminal prosecutions, the general rule is two years from the offense.11Pennsylvania General Assembly. Pennsylvania Consolidated Statutes Title 42 Chapter 55 – Limitation of Time Serious felonies like aggravated assault, robbery, burglary, arson, and kidnapping extend to five years. Major sexual offenses carry a twelve-year window. Murder, voluntary manslaughter, and certain offenses against minors have no deadline at all; prosecutors can bring charges decades later.
The Discovery Rule
Pennsylvania courts recognize an exception called the discovery rule. The clock does not start until you knew, or reasonably should have known through basic diligence, that you suffered an injury caused by someone else’s conduct. This matters most with latent harm, like a medical device that fails years after implantation or environmental contamination that takes time to surface. It will not rescue someone who ignored obvious signs of injury, but it prevents unfair outcomes when the harm was genuinely hidden.
Standards of Proof
What a party has to prove depends on whether the case is civil or criminal. In a criminal prosecution, the Commonwealth must prove the defendant’s guilt beyond a reasonable doubt, the highest standard in the American legal system. The burden sits entirely on the prosecution; the defendant does not have to prove innocence.
Civil cases use a lower standard called preponderance of the evidence. The plaintiff has to show their version is more likely true than not, essentially tipping the scales just past 50 percent. Some civil matters, like termination of parental rights, require an intermediate standard called clear and convincing evidence, which sits between the two.
When Federal Law Overrides State Law
Pennsylvania law does not control every situation. The Supremacy Clause of the U.S. Constitution establishes that federal law is “the supreme Law of the Land,” binding on state judges regardless of anything in state law to the contrary.12Constitution Annotated. Article VI – Supreme Law, Clause 2 When a Pennsylvania statute directly conflicts with federal law, the federal law wins. Federal preemption shows up most often in areas like immigration enforcement, bankruptcy, and certain workplace safety standards. Other areas overlap: employment discrimination is addressed by both federal statutes and the Pennsylvania Human Relations Act, and a claim can sometimes be filed in either state or federal court.
Where to Look It Up for Free
You do not need a paid legal research subscription to read Pennsylvania law. Three state sites cover almost everything a non-lawyer needs:
- Pennsylvania General Assembly (palegis.us) hosts the full text of the Consolidated Statutes, unconsolidated statutes, the state constitution, and pending legislation, searchable by keyword, bill number, or title.3Pennsylvania General Assembly. Statutes and the Constitution of Pennsylvania
- Pennsylvania Code and Bulletin (pacodeandbulletin.gov) contains every active administrative regulation and the weekly Bulletin listing proposed rule changes, executive orders, and public meeting notices.4Pennsylvania Code and Bulletin. About the Pennsylvania Code and Bulletin
- Unified Judicial System (pacourts.us) carries court dockets, case filings, and written opinions from the Courts of Common Pleas, the Superior Court, the Commonwealth Court, and the Supreme Court.
For federal statutes that might affect a Pennsylvania issue, the Office of the Law Revision Counsel at uscode.house.gov maintains the current U.S. Code and updates it daily. Cornell Law’s Legal Information Institute (law.cornell.edu) is a free alternative for federal statutes and Supreme Court decisions.
If You Can’t Afford a Lawyer
Pennsylvania has a statewide network of free civil legal aid programs. The Pennsylvania Legal Aid Network (PLAN) coordinates independent providers serving low-income residents. Eligibility is generally tied to 125 percent of the federal poverty guidelines, which in 2026 means an individual earning roughly $19,950 or a family of four earning roughly $41,250 may qualify.13Legal Services Corporation. LSC Says $2 Billion Needed to Address Low-Income Americans Unmet Civil Legal Needs Domestic violence victims can receive services regardless of income.
The right to a free attorney in criminal cases comes from the Sixth Amendment, and Pennsylvania public defender offices handle felony and misdemeanor cases for defendants who cannot afford counsel. In civil cases there is no general constitutional right to a free lawyer. Exceptions exist for certain high-stakes proceedings like termination of parental rights and involuntary civil commitment, where courts may appoint counsel. For everything else, legal aid organizations fill the gap as resources allow. You can find your local program through PALawHELP.org or by calling 1-800-322-7572.
