To file a tort claim, confirm your filing deadline, gather evidence of what happened and what it cost you, identify every defendant and the correct court, submit a complaint that meets that court’s requirements, and formally serve the defendant within the time the rules allow. If a government entity is involved, an administrative claim comes first. Everything below walks through how to file a tort claim in the order the steps actually happen, and where the traps are.
Check Your Filing Deadline Before Anything Else
Missing the statute of limitations is the single most common way people forfeit valid claims, and it happens no matter how strong the underlying evidence is. Check your deadline before you do anything else.
For personal injury, most states set the limit at two or three years from the date of injury, with the full range running from one year to six years depending on the state and the type of tort. Different claims can carry different windows within the same state — a products liability case may not share a deadline with a medical malpractice case. The clock usually starts on the injury date, though many states apply a discovery rule that delays the start until you knew or reasonably should have known about the harm.
Government defendants tighten this dramatically. Under the Federal Tort Claims Act, you have two years from when the claim accrues to file administratively.1eCFR. 32 CFR 750.36 – Time Limitations State and local governments often require a formal notice of claim within 90 days to one year of the incident. Those are the shortest deadlines in tort law, and missing them usually bars the claim entirely.
Identify Who to Sue and What You’ll Have to Prove
Before drafting anything, work out who is legally responsible and whether you can prove it. Getting the defendants wrong early creates problems that are expensive to fix later.
In a car accident, the potential defendants might include the other driver, their employer if they were working at the time, or a government entity responsible for road maintenance. In a premises liability case, the property owner, a tenant, and a maintenance company can all be on the hook. List every party whose conduct contributed.
Most tort claims run on negligence, which requires four things: the defendant owed you a duty of care, breached it, caused your injury (both in fact and as a foreseeable consequence), and produced actual damages. Intentional torts like assault, battery, and false imprisonment have their own elements, but negligence covers the overwhelming majority of personal injury lawsuits. If any of the four elements is missing, there is no claim to file.
Watch the Shared-Fault Rule in Your State
If the defendant argues you were partly responsible, your state’s fault framework can dramatically change what your case is worth — or whether it’s worth filing at all.
Most states apply comparative negligence and reduce your recovery by your percentage of fault. About a third use a modified rule with a 51% bar, letting you recover only if your fault stays below 51%. Another group sets that bar at 50%. A smaller number of states follow pure comparative negligence, allowing recovery even when you were 99% at fault, with the award reduced accordingly. A handful still apply contributory negligence, an all-or-nothing rule where any fault on your part, even 1%, defeats the claim entirely. In a contributory negligence state, evidence that you were slightly careless can end an otherwise strong case.
Build the Evidence File
Solid documentation is what separates claims that settle well from claims that go nowhere. Start collecting immediately. Memories fade, witnesses move, and physical evidence disappears faster than most people expect.
For injuries, request complete medical records showing diagnosis, treatment, prognosis, and costs, and ask for itemized billing rather than summary invoices. For lost income, get pay stubs showing normal earnings plus employer documentation confirming time missed. For property damage, secure repair estimates or replacement appraisals.
Police and incident reports carry particular weight because they were created close in time by someone with no financial stake in the outcome. Track down witness contact information and written statements while people still remember. Photographs of the scene, your injuries, and any property damage are among the most persuasive evidence you can gather, and they cost nothing.
Keep a running log of every out-of-pocket expense tied to the injury: transportation to appointments, prescriptions, home modifications, paid help for tasks you can no longer do. These small costs add up and are easy to forget months later when you’re calculating what to demand.
Your damages will fall into three buckets: economic (verifiable financial losses like medical bills and lost wages), non-economic (pain, suffering, emotional distress, loss of enjoyment — often capped by state law, especially in medical malpractice), and, in rare cases involving especially reckless or malicious conduct, punitive damages awarded to punish rather than compensate.
If a Government Entity Is Involved, File an Administrative Claim First
Suing a government body follows different rules than suing a private party. At the federal level, the Federal Tort Claims Act requires you to file an administrative claim with the responsible agency before you can file a lawsuit. Skipping this step gets your case dismissed.2U.S. Immigration and Customs Enforcement. Claims Under the Federal Tort Claims Act
Federal claims use Standard Form 95, available from any federal agency or the General Services Administration website. The form requires your personal information, a description of the incident, the nature of your injuries, and a specific dollar amount — the “sum certain.” Leaving that number off invalidates the whole claim.3U.S. General Services Administration. Claim for Damage, Injury, or Death – Standard Form 95
Once you file, the agency has six months to respond. If it denies the claim or fails to act within six months, you have six months from that point to file a lawsuit in federal court.1eCFR. 32 CFR 750.36 – Time Limitations
State and local government claims work similarly but on their own forms and timetables, often demanding notice within 90 days to a year. Some jurisdictions permit late-filing motions in limited circumstances, but the safer assumption is that the short deadline is hard. Check your state’s specific requirements the moment you realize a government entity may be involved.
File the Complaint
The complaint is the document that formally starts your lawsuit. It identifies you and the defendant, describes what happened, explains why the defendant is legally responsible, and states what compensation you’re seeking.4United States Courts. Civil Cases
Choose the Right Court
Where you file depends on the amount at stake, who you’re suing, and the legal basis for the claim. Federal courts handle cases involving federal law, claims against the federal government, and disputes between residents of different states when the amount exceeds $75,000. State courts handle everything else. For smaller disputes, small claims court offers a simplified process with lower fees, though recovery caps range from a few thousand dollars to $25,000 depending on the state.
Most courts publish blank complaint forms through the clerk’s office or their website. Use the forms specific to your court and claim type. Federal courts have become more demanding about pleading: the facts alleged must state a plausible claim, not just a possible one.
Filing Fees
Filing a civil complaint in federal district court costs $405, which is a $350 statutory filing fee plus a $55 administrative fee set by the Judicial Conference.5Office of the Law Revision Counsel. 28 USC 1914 – District Court Filing and Miscellaneous Fees State court fees generally run from under $100 to several hundred dollars. Small claims fees are typically much lower.
If you can’t afford the fee, most courts allow you to apply to proceed in forma pauperis, which waives or reduces it based on financial hardship. You’ll need to submit a sworn statement about your income and assets.
You can usually file in person at the clerk’s office, by mail, or through the court’s electronic filing system. Bring the original complaint plus copies for each defendant. Once filed, the court assigns a case number and returns stamped copies confirming the lawsuit is officially underway.
Serve the Defendant on Time
Filing does not notify the defendant. Service of process is a separate step, and the court cannot proceed against someone who hasn’t been formally told about the lawsuit. A judgment entered without proper service can be thrown out entirely.
The most reliable method is personal service, where a sheriff, constable, or private process server physically hands the complaint and summons to the defendant. The person performing service must be at least 18 and cannot be a party to the lawsuit.6Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons If personal delivery fails after reasonable attempts, many jurisdictions allow substituted service — leaving the documents with a responsible adult at the defendant’s home or workplace and mailing a copy. Certified mail with return receipt is available in some courts. If the defendant genuinely cannot be found despite diligent efforts, a court may authorize service by publication in a newspaper.
In federal court, you have 90 days from filing to complete service. Miss that deadline without good cause and the court must dismiss the action without prejudice, meaning you’d have to refile — assuming the statute of limitations hasn’t run out in the meantime.6Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons State deadlines vary and are sometimes longer.
After service, the server files a proof of service (sometimes called an affidavit of service) with the court, recording the date, time, location, and method. Without it, the court has no confirmation the defendant received notice, and the case stalls.
What Happens After You File
Once served, the defendant must respond. In federal court, the deadline is 21 days after service, or 60 days if the defendant waived formal service. Ignoring the complaint entirely risks a default judgment in your favor. The response is usually either an answer addressing each allegation or a motion to dismiss arguing the complaint fails as a legal matter.
If the case survives dismissal motions, it enters discovery, where both sides exchange information. This is often the longest and most expensive phase, running from a few months to over a year. The main tools are interrogatories (written questions answered under oath), requests for production (documents, records, electronic data), depositions (live sworn testimony recorded by a court reporter), and requests for admissions (statements the other side must admit or deny, with a failure to respond in time treated as an admission). Discovery disputes over relevance, privilege, and burden are common and add time and cost.
Most tort claims settle before trial. Negotiations often start with a demand letter laying out the facts, liability, and a specific figure, followed by a counteroffer and several rounds of adjustment. When direct talks stall, many courts require or encourage mediation, where a neutral third party helps the parties reach their own agreement rather than issuing a ruling. If settlement fails, the case proceeds to trial, where a judge or jury decides liability and damages.
Costs, Contingency Fees, and Handling It Yourself
Most personal injury attorneys work on contingency, taking a percentage of your recovery rather than charging hourly. The standard range is 33% to 40%, with the lower end typical for cases that settle before suit is filed and the higher end for cases that go to trial. If you recover nothing, you owe no attorney fee.
Fees are not the only cost. In most contingency arrangements, litigation expenses come out of the recovery on top of the attorney’s percentage:
- Court filing fees: $405 in federal court; varying amounts in state courts.
- Service of process: sheriff or process server fees, typically $50 to $150 per defendant.
- Expert witnesses: an average of $356 per hour for case review, $448 per hour for depositions, and $478 per hour for trial testimony, with medical specialists at the top of that range.
- Depositions: court reporter fees for transcripts, plus videographer costs when recorded on video.
- Medical records: provider copying fees that can reach several hundred dollars for extensive files.
A straightforward car accident case that settles early might run a few thousand dollars in costs. Complex litigation with multiple experts can push into the tens of thousands. Ask any attorney you’re considering whether the firm advances costs and deducts them from any settlement, or expects you to pay them as they come up.
You have the right to file and pursue a tort claim without an attorney, and people do it regularly in small claims court. In higher courts, self-representation is legal but risky. Courts hold unrepresented parties to the same procedural rules as attorneys, and while some judges show leniency on technicalities, that goodwill has limits and doesn’t cover substantive legal mistakes. Litigation involves hundreds of procedural decisions, each an opportunity to damage the case. If your claim involves significant damages, the contingency model means hiring a lawyer costs nothing upfront and improves your odds of a good outcome. For smaller disputes, small claims court is designed for non-lawyers and is usually the better path.
