State courts are the judicial systems that each state operates under its own constitution to hear the overwhelming majority of legal disputes in the United States, from traffic tickets and divorces to murder trials and multimillion-dollar contract fights. Roughly 90 percent of all cases filed in the country move through these courts, and the Tenth Amendment reserves to each state the power to structure its judiciary as it sees fit.1Congress.gov. U.S. Constitution – Tenth Amendment That independence is why the rules, deadlines, and even the names of courts can look different depending on which state you are in.
How State Courts Are Organized
Most states use a three-tier structure. Cases start in trial courts, move up to intermediate appellate courts if someone challenges the result, and can end at the state supreme court, which has the final word on state law.
Trial Courts
Trial courts are where cases begin. A judge, sometimes with a jury, hears testimony, examines evidence, and issues a verdict. Everything said is transcribed, which matters later if either side appeals. States typically split their trial courts in two: courts of general jurisdiction handle serious felonies and high-value civil disputes, and courts of limited jurisdiction take on high-volume matters like traffic violations, housing code cases, and small claims. Small claims caps vary widely, running from as low as $2,500 in some states to as high as $25,000 in others.
Intermediate Appellate Courts
If the losing side believes the trial court made a legal mistake, they can ask an intermediate appellate court to review it. These courts do not retry anything. A panel of judges reads the record and the written arguments and decides whether the law was applied correctly. The deadline to file a notice of appeal is tight, often 30 days from the date judgment is entered, and missing it usually means losing the right to appeal at all.
State Supreme Courts
At the top sits the state supreme court. Most have discretionary jurisdiction, meaning they pick the cases they hear, usually ones that raise questions important enough to need a definitive ruling. Their decisions bind every lower court in the state. One quirk worth knowing: not every state uses “supreme court” for its highest court. New York, famously, calls its trial-level courts the Supreme Court, which trips up people from out of state.
Specialty Courts
Many states also run problem-solving courts aimed at the causes behind certain offenses rather than just the punishment. More than 3,100 of these are active across the country, with drug courts accounting for over 1,600 on their own.2National Institute of Justice. Problem-Solving Courts: Fighting Crime by Treating the Offender Mental health courts, veterans treatment courts, and family treatment courts work on the same principle: accountability paired with treatment, with real consequences for noncompliance.
What Kinds of Cases State Courts Hear
State courts have general jurisdiction. That means they can hear almost any kind of case unless a specific law routes it somewhere else. In practice, their docket breaks into a few major areas.
Civil Disputes
Private disputes between people or businesses fill a huge share of the civil side. Personal injury and medical malpractice claims seek compensation for harm caused by negligence. Contract cases arise when someone breaks a signed agreement, whether a lease, an employment deal, or a construction contract. Before trial, both sides exchange evidence through discovery, which includes depositions, document requests, and written questions. Many states now require parties to try mediation before trial, especially in cases above a certain dollar threshold.
Criminal Cases
State prosecutors bring charges for violations of state penal codes, covering everything from shoplifting to homicide. Misdemeanors carry shorter jail terms and smaller fines; felonies can lead to years in state prison or life. If you face charges that could put you in jail, the Sixth Amendment guarantees you a lawyer, and the court must appoint one if you cannot afford to hire your own.3Congress.gov. Sixth Amendment – Overview of When the Right to Counsel Applies That right applies regardless of whether the charge is a felony or a misdemeanor.
Family Law and Probate
Divorce, child custody, child support, and domestic violence protective orders all move through state court. Custody disputes turn on what the judge decides is in the best interest of the child, a standard that gives judges real discretion. Probate courts handle wills, the distribution of a deceased person’s assets, and guardianship appointments for minors or incapacitated adults.
State Constitutional Questions
State courts also have the last word on their own state constitutions, which sometimes offer broader protections than the federal Constitution on things like privacy, speech, and search and seizure. When a state supreme court rules that its constitution grants a particular right, federal courts generally cannot override that reading.
Where State Court Authority Ends and Federal Court Begins
One practical question every litigant has to settle is which system their case belongs in. Federal courts can hear a case in two main situations. The first is federal question jurisdiction, where the claim arises under the U.S. Constitution, a federal statute, or a treaty.4Office of the Law Revision Counsel. 28 U.S. Code 1331 – Federal Question The second is diversity jurisdiction, which applies when the parties are citizens of different states and the amount in dispute is more than $75,000. Class actions have a higher threshold of $5,000,000 in total.5Office of the Law Revision Counsel. 28 U.S. Code 1332 – Diversity of Citizenship; Amount in Controversy; Costs If neither condition is met, the case stays in state court.
Plenty of cases qualify for both systems. When a plaintiff files in state court and the defendant would rather be in federal court, the defendant can remove the case within 30 days of being served, with all properly served defendants joining the removal.6Office of the Law Revision Counsel. 28 U.S. Code 1446 – Procedure for Removal of Civil Actions Some conduct violates state and federal law at the same time. Drug offenses are a familiar example: possession may be prosecuted under state law while trafficking is pursued federally. Both prosecutions can go forward separately without triggering double jeopardy, because state and federal governments count as separate sovereigns.
Filing Deadlines That Can End a Case Before It Starts
Every legal claim has a filing deadline called a statute of limitations. Miss it and the court will almost always dismiss the case no matter how strong the facts are. More claims die here than at any other stage.
How Long You Have
The window depends on the type of claim and the state. Most personal injury claims give you two or three years, though some states allow as few as one and others as many as six. Breach of a written contract usually gets longer, somewhere between four and ten years. Criminal statutes of limitations run on their own schedule, and the most serious offenses like murder have no deadline at all.
When the Clock Starts
The deadline usually runs from the date of the injury or breach. The discovery rule can delay that start: if you could not reasonably have known about the harm when it happened, the clock may begin when you actually discover it or should have. Medical malpractice is the classic example, since a surgical error might not surface for months or years. The discovery rule is not universal, so you cannot count on it to rescue a late filing.
Tolling
Certain conditions pause the clock entirely, which lawyers call tolling. The two most common are minority (the injured person is under 18) and mental incapacity. If the injured person is a minor when the claim arises, the clock typically does not start until they turn 18. Mental illness can also toll the deadline, though most states cap the extension even if the disability continues. Specifics vary, so anyone relying on tolling should verify the exact rule in their state.
How State Judges Get Their Jobs
The method for choosing state court judges varies dramatically, and it shapes the kind of bench each state ends up with.
In some states the governor appoints judges, usually with state senate confirmation, much like the federal system. A smaller number use legislative appointment, where the legislature itself selects judges without the governor playing a role.
Many states elect their judges instead. Partisan elections list candidates with a party label; nonpartisan elections leave party affiliation off the ballot. Supporters say elections keep judges accountable to the public. Critics say campaigns pressure judges to fundraise and signal positions on issues they will later decide. Judicial ethics codes restrict what candidates can say publicly about legal questions.
A widely adopted hybrid is merit selection, often called the Missouri Plan after the state that pioneered it. A nonpartisan commission reviews applicants, interviews them, and sends the governor a short list. After an initial term, the judge faces a retention election where voters vote yes or no on keeping them, with no opposing candidate on the ballot. Roughly 21 states and the District of Columbia use some form of merit selection for at least their highest court, making it the most common method at the state supreme court level.
Filing a Case in State Court
The practical side is less mysterious than it looks once you know the pieces.
Picking the Right Court
Jurisdiction usually follows geography. You file where the defendant lives, where a contract was signed, or where an injury happened. Each state’s judicial branch publishes directories and maps showing which courthouse covers which area. Filing in the wrong court can get your complaint dismissed outright, so this step matters.
The Clerk and the Fees
The Clerk of Court is the administrative gatekeeper for every courthouse. The clerk’s office accepts filings, keeps the official case record, and collects filing fees. A small claims filing might run under $100, while a complex civil lawsuit can cost several hundred dollars or more depending on the state. Clerks’ offices provide standardized forms and written instructions for self-represented litigants, though staff cannot give legal advice. Fee waivers are available in most states for people who cannot afford to pay.
Electronic Filing and Local Rules
More and more state courts require documents to be filed electronically rather than on paper. A Federal Judicial Center study found that among the state court systems reviewed, more than half had implemented mandatory e-filing for attorneys in at least some of their courts.7Federal Judicial Center. Electronic Filing in State Courts Self-represented litigants are often exempt and can still file on paper. Each court also publishes its own local rules on formatting, page limits, and scheduling, and violating one of these, even a minor formatting requirement, can get a filing rejected. Reading the local rules before you file anything is the simplest way to avoid a procedural stumble.
Enforcing a Judgment After You Win
Winning a case and collecting the money are two different things. A judgment is a legal declaration that someone owes you. It does not force them to pay. The winner, now called the judgment creditor, has to take further steps.
Wage Garnishment
One common tool is wage garnishment, which redirects part of the debtor’s paycheck to the creditor. Federal law caps garnishment for ordinary consumer debts at the lesser of 25 percent of disposable earnings or the amount by which weekly disposable earnings exceed 30 times the federal minimum wage.8Office of the Law Revision Counsel. 15 U.S. Code 1673 – Restriction on Garnishment Some states set lower caps that protect debtors more, so the federal number is a ceiling, not a universal rule.
Judgment Liens
A judgment can also be recorded as a lien against the debtor’s real estate. The creditor files a certified copy of the judgment with the county recorder where the property sits. Once recorded, the lien attaches to the property and has to be paid before the debtor can sell or refinance. How long a lien lasts before expiring varies by state, from as few as five years to 20 or more, and most states let the creditor renew it. Homestead exemptions, which also vary by state, may partially or fully protect the debtor’s primary residence.
Time Limits on Enforcement
Judgments do not last forever. Each state sets a deadline for enforcing or renewing a judgment, and if that window closes without action, the judgment is treated as satisfied by operation of law even if nothing was ever paid. Anyone holding a judgment should calendar those deadlines carefully. Losing enforcement rights after already winning is an avoidable and painful result.
