How to Sue Someone in 2026: Step-by-Step Guide (No Lawyer)

To sue someone, start with a formal demand for payment. If they ignore it, file a complaint at your local small claims court (filing fees run $30 to $75 in most states), get the defendant served, and show up to the hearing with your proof. Here's the part nobody tells you: most cases never make it in front of a judge. Around 70% resolve after a demand letter, before anyone files a thing.

The short version:

I Want to Sue Someone: Where Do You Start?

You're angry. Someone took your money, wrecked your stuff, or broke a promise, and now you're typing "I want to sue someone" into Google at midnight. Good. That anger is useful. Let's point it somewhere.

Before you do anything, answer three questions:

1. Can you put a dollar amount on the harm? Courts fix problems with money. "He owes me $1,800 for the deck he never built" is a case. "He's a jerk" is not.
2. Do you have proof? Think texts, emails, receipts, photos, the contract they never honored. You don't need a mountain. Just enough to show what happened.
3. Can the person actually pay? Win against someone with no job and no bank account, and all you hold is paper. You can still collect. It just takes longer.

Yes to the first two? You've got a real case. And no, the first stop is not the courthouse. It's a demand letter. It costs next to nothing, takes minutes, and kills most disputes before any judge gets involved. The rest of this guide covers everything else, letter to collection.

What Does It Mean to Sue Someone?

Suing someone just means filing a civil lawsuit. You're asking a court to make them pay you, or make them do the thing they promised and never did.

Civil is not criminal. Nobody goes to jail here. Criminal cases are the government's job. A civil case is yours. You're the one standing up and saying: this person wronged me, and I want it fixed.

A few terms you'll run into:

• Plaintiff - you, the one filing.
• Defendant - the person or company on the receiving end.
• Complaint - the form that starts the case. What happened, what you want.
• Summons - the notice telling the defendant they're being sued and when to show up.
• Discovery - the evidence-swapping phase. Small claims mostly skips it.
• Judgment - the final call. Win, and it spells out what they owe you.

People sue people. People sue companies. Companies sue each other. None of it requires wealth or a law degree. Millions of Americans file on their own every year and do just fine.

Which court you file in comes down to the dollar amount. Small claims handles the everyday stuff, fast and cheap. Regular civil court is for the big, messy claims.

Can You Sue Someone? How to Know If You Have a Case

Not every bad situation is a legal claim. But many common ones are.

You likely have a valid case if someone:

• Broke a written or verbal contract
• Damaged or destroyed your property
• Owes you money they won't pay back
• Lied to you in a way that caused financial harm
• Hurt you through careless actions
• Wrongfully kept your security deposit
• Failed to complete work you paid for

The key question is: did someone cause you real harm that can be fixed with money? If yes, you probably have a case.

One thing people learn the hard way: winning gets you a judgment, not a check. A defendant with no money and no assets can make that judgment tough to enforce. Our guide on suing someone with no money covers when it still makes sense.

When in doubt, start with a demand letter. It's low cost and can reveal fast whether the other side will pay. Many people pay the moment they get a formal notice.

Can You Sue Someone for Emotional Distress?

Yes. You can sue someone for emotional distress. But it's harder to prove than a simple money claim.

There are two legal types of emotional distress claims:

IIED (Intentional Infliction of Emotional Distress) means someone did something extreme on purpose to cause you emotional pain. Stalking, harassment, and threats can qualify. A rude comment doesn't meet the bar.

NIED (Negligent Infliction of Emotional Distress) is the careless version. They didn't set out to hurt you, but their recklessness caused real emotional harm anyway.

To win either type, you need to show real harm. Courts look for:

• Medical records or a doctor's diagnosis
• Therapy or counseling bills
• Proof you missed work or lost income
• Witness testimony about how your life changed

A vague claim of "I felt bad" won't win. Emotional distress claims work best when paired with another claim, like harassment or personal injury. We break down the details in our guide on suing for emotional distress.

Can You Sue Someone for Slander?

Yes. You can sue someone for slander. Slander is a form of defamation, and defamation is a real legal claim.

To win, you need to prove four things:

1. The person made a false statement of fact (not just an opinion)
2. They said it to at least one other person
3. The statement was about you specifically
4. It caused you real harm (losing a job, losing clients, damaged relationships)

Opinions don't count. "I think Jane is a bad contractor" is an opinion. "Jane stole money from me" when that's not true is a false statement of fact. Only the second one can lead to a slander lawsuit.

These cases are complex and hard to win without solid evidence. Read our full guide on suing for defamation before spending money to file.

Small Claims Court vs Civil Court: Which One Do You Need?

Get this choice right and everything gets easier: your cost, your timeline, whether you pay a lawyer at all. For almost everyone reading this, small claims is the answer. The side-by-side:

The rule of thumb: if your claim fits under your state's small claims limit, file there. Check every state's small claims limit to see where you stand. Only go to civil court when the money at stake is too big for small claims, and be honest with yourself about whether the extra cost is worth it.

How to Sue Someone: Step-by-Step Process

Here's exactly how to sue someone, from first step to final resolution. Follow these in order.

Step 1: Send a Demand Letter First

Before you file anything in court, send a demand letter. This is a formal written notice. It tells the other person what happened, what they owe, and what you'll do if they don't respond.

Demand letters work. About 70% of cases settle without ever going to court. A formal letter changes the math for the other side. Suddenly you're not a complaint they can ignore. You're a person about to file. Plenty of people quietly pay the minute that letter lands.

A good demand letter has four parts:

• What happened, in plain terms
• The exact amount you want
• A deadline (14 to 30 days is typical)
• What happens if they blow it off: you file

You can write one yourself. Check out this guide on how to write a demand letter for a full walkthrough.

Or let PettyLawsuit handle the whole thing. The letter goes out by certified mail the same day. Then the system keeps going: phone calls to the other side, follow-up emails, and a Final Notice on day 10. That persistence is why it works. PettyLawsuit has helped 5,000+ people take action, and 70% of cases resolve without ever stepping into court.

Skipping this step is the classic rookie move. Don't. Most cases end right here. The ones that don't are stronger in court, because you can show the judge you tried.

Step 2: Figure Out Where to File

If the demand letter doesn't work, you need to pick the right court.

Small claims court is the best starting point for most people. It's faster, cheaper, and built for people without lawyers. Each state sets its own dollar limit. Most states cap claims between $5,000 and $25,000.

Civil court handles bigger claims and more complex legal issues. Cases here are slower and more expensive. You'll usually need a lawyer.

Check our guide on how to file small claims in every state to find your state's limit and process. If your claim is under the limit, go small claims. It's almost always the better choice for amounts under $10,000.

You also need to file in the right location. That usually means the county where the defendant lives or where the incident happened. Suing someone far away? Our guide on how to sue someone in another state covers that.

Step 3: Draft and File the Complaint

The complaint is the paper that makes it official. Who you are, who wronged you, what they did, and what you want the judge to do about it.

In small claims court, filing is simple. Most counties have a one-page form. Get it at the courthouse front desk or download it from the court's website. Fill it out, pay the filing fee, and you're in the queue.

In civil court, the complaint is more detailed. It needs to state your legal theory, list the facts, and spell out the damages you're seeking. Most people hire a lawyer to draft civil court complaints.

Most states charge $30 to $75 to file a small claims case, though some big-city courts want more. Civil court? The filing alone runs $200 to $500.

The court stamps your papers, hands you a case number, and you're officially in the system. Keep copies of every single page.

Step 4: Serve the Defendant

After filing, you have to officially notify the defendant. This is called service of process.

The defendant has to actually receive your complaint plus a summons, the notice telling them when and where to respond. No valid service, no case.

The usual options:

• Certified mail, which some states let the court clerk handle for a few dollars
• A sheriff, marshal, or constable
• A private process server
• Any adult who isn't you, delivering by hand

Rules vary by state. Some states handle service when you file. Others require you to arrange it. Ask the court clerk when you file, and read our guide on how to serve court papers so nothing gets thrown out on a technicality.

The case can't move forward until the defendant is properly served. If service fails, the case gets delayed.

Step 5: Gather Your Evidence

In small claims court, discovery is minimal or skipped entirely. You just show up with your evidence on the hearing date. Bring the receipts. Literally: contracts, invoices, texts, photos, emails, anything that backs your story.

In civil court, discovery can be intense. It includes written questions, document requests, and depositions. Discovery alone can take three to twelve months in a civil case.

Even in small claims, prepare like it matters, because it does. Print your screenshots. Put everything in time order. Three copies of everything: the judge gets one, the other side gets one, you keep one. Our guide on how to prepare for small claims court has a full one-week countdown plan.

Step 6: Try to Settle

Even after you file, settlement is still on the table. The goal isn't to win at trial. The goal is to get what you're owed.

Most civil cases settle before trial, and for good reason. A deal saves both sides time and money, and it trades the gamble of a trial for a sure thing.

Turning down a fair offer just to make a point is expensive pride. If they offer 80% of what you're owed, do the math: is the extra 20% worth another six months of stress?

Get any settlement agreement in writing and signed before you dismiss the case.

Step 7: Go to Your Hearing

If you can't settle, you go to court. Both sides present their case. The judge decides who wins.

Small claims hearings move fast. Fifteen minutes is common, an hour is long. You tell your story, hand over your evidence, and answer whatever the judge asks.

In civil court, trials can last days or weeks. Lawyers make opening and closing arguments. Witnesses testify. Both sides challenge each other's evidence.

Win, and the court enters a judgment ordering the defendant to pay. Whether they actually do is a separate battle, which brings us to the last step.

Step 8: Collect Your Judgment

Winning is one thing. Getting paid is another. Some defendants pay quickly. Others drag their feet or ignore the judgment entirely.

If the defendant won't pay, you have legal tools to force collection:

• Wage garnishment - their employer sends you a slice of every paycheck until the debt clears.
• Bank levy - the court freezes money in their account and routes it to you.
• Property lien - a claim against their property that has to be paid off before they can sell or refinance.

Each tool needs a bit of extra paperwork after your judgment. The clerk can point you to the right forms. Our guide on collecting a small claims judgment covers each one in detail. It takes patience. But the tools exist, and they work.

How to Sue a Company

Suing a company follows the same playbook, with two twists that trip people up: the name and the service. We have a full guide on how to sue a corporation, but here are the basics.

Find the Right Legal Name

You can't just write "Bob's Plumbing" on a court form. "Bob's Plumbing" might legally be BP Services LLC, and a judgment against a name that doesn't exist is worth nothing. Find the real one:

• Your state's Secretary of State website (free business search)
• The fine print in the company's website footer or terms of service
• Their Better Business Bureau listing

If the business is an LLC or corporation, use the registered name exactly as it appears in state records.

Serve the Company Correctly

Companies can't receive papers in person the way a human can. You serve them through their registered agent instead. Every registered company has one: a person or service that accepts legal papers on its behalf. They're listed in the same Secretary of State database, one search away. Serve the agent the same way you'd serve a person.

What You Can Sue a Company For

Most disputes people have with businesses fall neatly into small claims court territory:

• Contractor took your money and didn't finish the job
• Business damaged your property
• Company won't refund you after a failed service
• Landlord refuses to return your security deposit
• Seller sent the wrong or defective product

If your employer wronged you, there are additional legal routes. Our guide on suing your employer covers workplace disputes in detail.

For most money disputes with a business, small claims is the fastest and cheapest path. Companies often settle quickly once they're officially served. A lawsuit is bad PR, and many businesses would rather pay than show up to court.

Can You Sue Someone Without a Lawyer?

For small claims court, yes. The whole system was built so regular people could use it. One-page forms. Casual hearings. Judges who explain things as they go, because they talk to non-lawyers all day. California and Michigan go further and ban lawyers from small claims hearings entirely.

Somebody owes you $2,000 and won't pay? You don't need a lawyer for that. A demand letter and a small claims filing will do the job, and you keep the whole judgment instead of handing a third of it to someone in a suit.

When You Should Hire a Lawyer

Some fights are too big to take on alone:

• You got seriously hurt and the medical bills are piling up
• The other side already lawyered up
• The claim blows past your state's small claims limit
• It's a messy business or contract fight with a lot of moving parts
• Slander, defamation, or emotional distress (genuinely hard to win solo)
• A workplace case like wrongful termination or discrimination

Facing a lawyer alone is rough. They know the procedural tricks. You don't. Sometimes paying for your own is just the price of a fair fight.

Finding one is easier than people think. Google your state plus "bar lawyer referral" and you'll land on your state bar's matching service. The first call is often free. And injury lawyers almost never charge upfront. They take a cut of the win instead.

How Much Does It Cost to Sue Someone?

Honestly? Less than you think. Most disputes die at the demand letter stage, so most people never spend more than $50 on the whole thing.

One more thing people miss: if you win in small claims, the judge can order the defendant to pay back your filing and service fees on top of your claim. You have to ask for it, but your costs are often a loan, not a loss.

For a full breakdown with real fees from real counties, see our guide on how much it costs to sue someone.

The bottom line: start cheap. A demand letter costs less than a tank of gas. Small claims costs under $200. Only escalate to civil court when the amount justifies it.

What Does a Personal Injury Lawsuit Look Like?

A personal injury lawsuit is a civil case where someone's carelessness left you physically hurt. Think car crashes, a dog that bit you, a fall on an icy stairwell the landlord never salted, a surgery that went wrong.

These cases play by different rules than the small claims disputes in this guide:

• The money at stake is bigger: medical bills, lost wages, pain and suffering
• You'll almost certainly want a lawyer
• They drag. One to three years is normal
• The opponent is usually an insurance company with a legal team that does this all day

Winning one means proving four things:

1. The other person owed you some level of care (drivers owe it to everyone on the road)
2. They blew it
3. That failure is what hurt you
4. The injury cost you something real

Injury lawyers take 25% to 40% of the recovery, and that's standard. The part that isn't flexible: the deadline. Every state puts a clock on injury claims, sometimes just two years. Talk to someone before it runs out.

Common Mistakes When You Sue Someone

Most people who lose in small claims court don't lose on the facts. They lose on the details. Avoid these:

• Skipping the demand letter. Judges sometimes ask if you tried to resolve things first. And you skip the step that settles 70% of cases.
• Suing the wrong name. "Joe's Auto" might legally be "JSA Enterprises LLC." Sue the sign instead of the legal entity and your judgment can be worthless.
• Waiting too long. There's a filing deadline (the statute of limitations), usually 2 to 6 years depending on the claim. Plenty of solid cases die of old age.
• Asking for a fuzzy number. "Around $2,000" is weak. "$1,847 based on this invoice" wins. Bring the math.
• Forgetting to ask for your costs. Filing and service fees can be added to your judgment, but only if you ask at the hearing.
• Winning and walking away. The court won't collect for you. If they don't pay, use garnishment, levies, and liens.

Frequently Asked Questions

How do you sue someone?

Demand letter first. If they ignore it, file a complaint with your local small claims court (filing runs $30 to $75 in most states), get them served, and show up with your proof. A surprising number of cases settle before the hearing ever happens.

What can you sue someone for?

Anything that cost you real money: a debt they won't repay, a broken contract, wrecked property, a half-finished job you already paid for, a security deposit that vanished. Quick test: can money fix the harm? Then you've probably got a claim.

Can you sue someone without a lawyer?

Yes, and in small claims court that's the norm, not the exception. Grab the complaint form from your courthouse, pay the fee, serve the other side, then tell the judge your story. A few states won't even let lawyers into small claims hearings.

How do you sue a company?

Find the company's real legal name first (free search on your Secretary of State's site) and put that exact name on the complaint. Then serve their registered agent, listed in the same database. Businesses tend to settle fast once papers land. Court is bad for business.

How much does it cost to sue someone?

Under $50 for a demand letter. Small claims adds $30 to $75 in filing fees plus a service fee. Hiring a lawyer for civil court? Now you're into five figures. Start cheap and only escalate when the dollars justify it.

How long does it take to sue someone?

Small claims moves fast: 30 to 90 days from filing to hearing in most courts. Regular civil cases crawl along for one to three years. And if a demand letter is going to work, it usually works within a few weeks.

Is it worth suing someone over a small amount?

Usually, yes. Your total small claims cost runs under $200, and the judge can make the loser pay it back. We ran the math on a $500 dispute and it still works out in your favor.

Can you sue someone for emotional distress?

Yes, but bring receipts. Therapy bills, a diagnosis, proof you missed work. "I was really upset" loses; documented harm wins. These claims do best stacked on top of another one, like harassment or personal injury.

What happens if someone doesn't pay after you win?

The court hands you tools: garnish their wages, freeze a bank account, put a lien on their property. Each one takes a form and a small fee. Slower than you'd like, but the leverage is real, and the clerk will point you to the paperwork.

Can you sue someone in a different state?

Yes. Venue rules usually send you to where the defendant lives or where the whole thing happened. One call to that county's court clerk sorts out the right courthouse before you pay a single fee.
