How to Sue Someone

Table of Contents

To sue someone, first check if your case qualifies for small claims court. These courts handle simple disputes about money or property, usually under a set limit (like $10,000 in California). Make sure you file within the legal time limit (statute of limitations) and in the right court based on where the issue happened or where the person lives.

Before filing, try to solve the problem by sending a written demand for payment or resolution. If that fails, fill out the proper court forms and file them either in person or online. You’ll also need to pay a small filing fee, unless you qualify for a fee waiver. After filing, you must legally serve the other person with the court papers using an approved method, like personal service or certified mail.

Once the court date is set, gather all your evidence—contracts, photos, receipts, messages—and practice explaining your case clearly. On the hearing day, show up prepared and respectful. The judge will hear both sides and make a decision. If you win, it’s your job to collect the money, using legal tools if needed.

What Is Small Claims Court?

Small claims court is a special court where people can solve legal problems without needing a lawyer. It’s made for simple cases about money or property. These cases usually involve smaller amounts—up to $10,000 in California, $6,000 in Ohio, and $20,000 in Texas.

People use small claims court for things like:

  • Unpaid rent or security deposits
  • Car accident damage
  • Broken contracts
  • Unpaid loans
  • Property damage

The court process is faster and cheaper than regular court. You don’t need a lawyer, and the judge usually makes a decision the same day or soon after. The rules are simpler so regular people can explain their side without legal training.

Small claims courts only handle civil cases. That means no criminal charges are involved. Both sides must be individuals or businesses, and the goal is usually to get money, not to punish anyone.

Who Can Sue and Be Sued?

Anyone 18 or older can file a case in small claims court. If you’re under 18, a parent or guardian must file for you. Businesses, landlords, and organizations can also sue or be sued in small claims.

You can sue someone if they owe you money or damaged your property. Common targets include:

  • A person who didn’t repay a loan
  • A landlord who kept your deposit
  • A business that didn’t deliver what you paid for
  • A neighbor who damaged your property

To sue correctly, you must name the right person or business. Use their full legal name. If you’re suing a company, check business records to get the exact legal name. If you get it wrong, your case might be dismissed, and you’ll have to start over.

In some states, like California and Ohio, you can sue more than one person in the same case if they’re all involved in the problem.

When and Where to File

You must file your claim before the legal deadline, called the statute of limitations. This limit depends on your case type and your state:

  • Personal injury: 2 years (CA), 2 years (OH)
  • Written contracts: 4 years (CA), 6 years (OH)
  • Verbal agreements: 2 years (CA), 6 years (OH)
  • Property damage: 3 years (CA), 4 years (OH)

Filing too late means the court will reject your case—even if you’re right.

You must also file in the correct venue (location). Usually, that means:

  • Where the defendant lives or does business
  • Where the event happened (like a car accident or broken contract)
  • Where the property is located (like in a landlord-tenant case)

Each small claims court covers a certain area. For example, in Los Angeles County, you can file at your local courthouse. In Ohio or Texas, you’ll use county or municipal courts.

Pre-Filing Steps

Before you file a lawsuit, the court expects you to try solving the problem first. This step is called making a demand. You can do this by:

  • Talking to the other person
  • Sending a demand letter by mail or email
  • Asking for a payment deadline (for example, “Please pay me by July 15”)

A demand letter should clearly say:

  • What happened
  • How much money you want
  • Why you believe they owe you

Keep a copy of the letter as proof. If they ignore it or refuse to pay, then you can move forward with the lawsuit.

Also collect all your evidence before filing:

  • Contracts or written agreements
  • Receipts, invoices, or bills
  • Text messages, emails, or letters
  • Photos or videos
  • Witness names and contact info

Double-check the statute of limitations and make sure your case is still valid. Also confirm that small claims court is the right type of court for your issue.

Filing the Claim

To start your small claims case, you need to fill out the right court forms. These forms ask for your name, the other person’s name, the reason for the lawsuit, and the amount of money you’re asking for. Most courts have a specific form called a “Plaintiff’s Claim” or “Complaint.” You can get these forms online, at the courthouse, or from the court’s self-help center.

Once the form is complete, you have to file it with the court. You can usually do this in person at the courthouse or online if your local court has an e-filing system. Some courts also accept filings by mail. When you file, the court clerk will give you a court date and stamp your documents.

There’s also a filing fee, which depends on how much money you’re asking for. In California, for example, the fee ranges from $30 to $75. If you can’t afford the fee, you can ask the court for a fee waiver. You’ll need to fill out an extra form to show your income and expenses.

Serving the Defendant

After you file your claim, you must legally deliver a copy of the court papers to the person or business you’re suing. This is called serving the defendant, and it’s a required step. The court won’t move forward until this is done correctly.

You can’t serve the papers yourself. Someone else who’s at least 18 and not involved in the case must do it. There are a few legal ways to serve:

  • Personal service: Someone hands the papers directly to the defendant.
  • Substitute service: If the person isn’t home, the server can leave the papers with a responsible adult at their home or workplace and also mail a copy.
  • Certified mail: In some states, the court clerk can send the papers by certified mail with a return receipt.
  • Sheriff or process server: You can pay a professional to deliver the documents.

The person who serves the papers must fill out a Proof of Service form. This form tells the court when, where, and how the papers were served. You must file this proof with the court before your hearing date.

If the defendant isn’t served properly or on time, the judge may cancel the hearing. You’ll need to start over or request a new court date.

Preparing for Court

Once your court date is set and the defendant is served, it’s time to get ready for the hearing. Preparation is key. You only get one chance to present your case, and the judge will expect facts, not just opinions.

Lawyer reflecting on what is the best strategy in how to sue someone

Start by organizing all your evidence. Put documents in the order of how events happened. Make copies for yourself, the judge, and the other side. Common evidence includes:

  • Contracts or written agreements
  • Texts, emails, or messages
  • Receipts, estimates, or invoices
  • Photos or videos
  • Police reports or repair bills

Write down a clear timeline of what happened. Judges appreciate when you explain your story in a simple, logical order. Stick to facts—what happened, when, where, and how much money is involved.

If you have witnesses, ask them to come to court. They must have personal knowledge of what happened. If someone won’t come willingly, you can ask the court to issue a subpoena to require their attendance.

Practice what you’ll say. You’ll need to explain your side clearly and briefly. The judge may ask questions, so be ready to answer. Keep your answers honest and to the point.

Attending the Hearing

On your court date, arrive early—at least 30 minutes before the hearing. Bring all your documents, copies, and any witnesses. Dress neatly and speak respectfully in the courtroom.

When your case is called, both sides stand before the judge. The plaintiff (the person suing) usually speaks first. You’ll explain what happened, show your evidence, and state the amount of money you’re asking for. The judge may interrupt to ask questions, so stay focused and answer clearly.

Next, the defendant gives their side. They can deny the claim, explain their version, or show their own evidence. You may get a chance to respond briefly.

The judge looks at all the facts and may ask more questions before making a decision. In some courts, the judge gives a decision right away. In others, the decision is mailed to you later.

Stay calm and polite, even if you disagree with the other side. Arguing or interrupting can hurt your case.

After the Judgment

After the hearing, the judge will issue a judgment. This is the official decision about who wins and how much money, if any, must be paid. You’ll get a written copy by mail or directly after court, depending on your location.

If you win the case, the court doesn’t collect the money for you. It’s your job to contact the other side and ask for payment. If they don’t pay, you can ask the court to help you collect using legal tools like:

  • Wage garnishment – part of their paycheck goes to you
  • Bank levy – money is taken from their bank account
  • Lien – a legal hold placed on their property

If you lose the case, you may still owe court fees or have to respond to a claim from the other side. In some states, you can file an appeal, but only within a short time (usually 30 days). Appeals may not be allowed in all small claims cases, so check your state’s rules.

Whether you win or lose, make sure to follow all court orders and deadlines.

If You’re Being Sued

If you get sued in small claims court, don’t ignore it. The court will send you a summons or notice of claim with the date, time, and reason for the case. You must show up, or the judge can rule against you automatically—this is called a default judgment.

Start by reading the claim carefully. Look at:

  • Who is suing you
  • Why they’re suing
  • How much they’re asking for

If the claim is wrong, you can defend yourself. Prepare your evidence, such as receipts, photos, messages, or contracts. Bring anything that proves your side of the story. You can also bring witnesses to support your case.

If you believe the other person actually owes you money, you can file a counterclaim. You’ll need to fill out a form and possibly pay a fee. The court will hear both sides on the same day.

You can also try to settle the case before the hearing. If both sides agree, you can avoid going to court. Just make sure any agreement is in writing and signed by both parties.

Legal Help and Resources

Small claims court is meant to be simple, but legal help can still make things easier. Many courts offer self-help centers where staff can explain the process, help with forms, and answer questions. They can’t give legal advice, but they can guide you through court rules and deadlines.

You can also find free or low-cost legal aid through nonprofit groups, especially if your income is low. In California, try Legal Aid Foundation of Los Angeles (LAFLA). In Ohio, use Ohio Legal Help to find local assistance. In Texas, check with your county law library or legal aid clinics.

Many court websites have online tools where you can:

  • Download court forms
  • Watch videos about court procedures
  • Use form-filling wizards
  • Find your court’s contact info

Some states even offer mediation services, where a trained neutral person helps both sides reach an agreement without going to trial. This can save time and stress.

Having the right help increases your chances of success in small claims court—whether you’re suing or being sued.
