How to File (or “Commit”) a Case in Court in the USA: Step-by-Step Guide 2025

y Becky | Becky Legal

Many people face legal challenges at some point in life—whether it's a contract dispute, unpaid wages, personal injury, family issue, or tenant disagreement. But the question often arises: “How do I start a case in court?” Or as some say, “How do I commit a case?”

In the United States, filing a case in court is a formal legal process governed by strict rules and deadlines. While the term "commit a case" is sometimes used informally, the correct phrase is “file a case” or “initiate a lawsuit.”

In this article, I’ll walk you through:

What it means to file a case
The types of courts and which one you need
Step-by-step instructions for filing
Documents and fees required
What to expect after you file
Common mistakes to avoid

This guide is useful for plaintiffs (the person bringing the case)—not criminal defendants. If you're being sued or charged with a crime, you need a defense attorney immediately.

I. Understanding the Basics: What Does It Mean to File a Case?

To "file a case" means to officially start a legal process by submitting written documents (called “pleadings”) to a court. This notifies the court and the other party that you're seeking a legal remedy—such as money, an order, or justice.

Depending on the situation, you may file in:

Civil court (e.g., for divorce, personal injury, contracts, property disputes)
Small claims court (for low-dollar disputes)
Family court (for custody, support, or adoption)
Federal court (for constitutional issues, federal law, or large interstate matters)

Let’s break it down step by step.

II. Step-by-Step Guide to Filing a Case in Court

Step 1: Determine If You Have a Legal Claim

Ask yourself:

Have you been harmed or wronged?
Do you have evidence?
Has your case passed the “statute of limitations”? (Each legal issue has a deadline for filing)
Can the other party be located and held responsible?

If your answer is “yes” to most of these, you may have a case worth pursuing.

If you're unsure, consult a lawyer to avoid wasting time and money.

Step 2: Choose the Right Court

Jurisdiction matters. Filing in the wrong court can get your case thrown out.

There are 3 major types of courts:

Small Claims Court – Handles disputes typically under $10,000. No lawyer required.
State Court (Civil) – Handles personal injury, family law, contracts, etc.
Federal Court – Handles cases involving federal law, civil rights, or parties from different states with over $75,000 in damages.

Each court has rules about:

The amount of money at stake
The type of issue
The location of the people involved

Tip: If it’s a simple case (like an unpaid loan, damaged property, or security deposit), small claims court is quicker and more affordable.

Step 3: Identify the Parties

In every case:

The plaintiff is the person who files the lawsuit.
The defendant is the person or company being sued.

Make sure you:

Use the correct legal name (especially for businesses)
Include full addresses
List all parties involved, if more than one

Step 4: Prepare Your Complaint or Petition

This is the most important document. It tells the court:

What happened
Why you’re filing
What relief or compensation you want

Typical elements of a complaint include:

Caption (names of parties, court name, case number)
Statement of jurisdiction (why the court has authority)
Facts of the case (what happened, when, where)
Legal claims (e.g., breach of contract, negligence)
Relief sought (money, injunction, etc.)

In some courts (like family court), this may be called a petition instead of a complaint.

Tip: Use plain, factual language. Don't exaggerate or use emotional language—just the facts.

Step 5: Complete the Summons

The summons is a separate form issued by the court that notifies the defendant that they are being sued and must respond.

After filing your complaint, the court clerk usually:

Assigns a case number
Signs and issues the summons
Gives you copies for service

Step 6: File Your Documents With the Court Clerk

You must now file the complaint and summons with the clerk of the appropriate court.

This can usually be done:

In person at the courthouse
By mail
Electronically (e-filing, in many jurisdictions)

You must pay a filing fee, which varies by court and case type. Typical fees:

Small claims: $30–$200
Civil court: $200–$500
Family court: $50–$400

If you can’t afford the fee, you can file a fee waiver application (also called In Forma Pauperis).

Step 7: Serve the Defendant (Service of Process)

You must now “serve” the defendant with:

A copy of the complaint
A signed summons

This ensures the defendant is officially informed.

Service must be done by:

A process server
Sheriff’s office
Certified mail (in some states)
Anyone 18+ who is not a party to the case

You’ll then submit a proof of service form to the court.

Don’t skip this step! Improper service can result in dismissal.

Step 8: Wait for the Defendant’s Response

After being served, the defendant has a specific number of days to respond:

Typically 20–30 days in civil court
14 days in federal court

They can:

File an Answer (agree/disagree with allegations)
File a motion to dismiss
Do nothing (in which case, you may win by default)

Step 9: Discovery and Pre-Trial Motions

Once the defendant responds, the case enters pre-trial phase, which includes:

Discovery (exchanging documents, witness lists, etc.)
Depositions (interviewing witnesses under oath)
Motions (e.g., to dismiss, compel evidence, or get a summary judgment)

This is where things can get complex. Lawyers often get involved here.

Step 10: Settlement or Trial

At this point, most cases settle out of court through negotiation or mediation.

If not, the case goes to trial:

A bench trial (judge decides)
Or a jury trial (jury of peers)

At trial, both sides present evidence and arguments. The judge or jury then issues a decision.

III. What Happens After a Decision?

If You Win:

The court may award monetary damages, or
Issue injunctions or orders

But remember: courts don’t enforce judgments. If the other side doesn’t pay, you may need to:

Garnish wages
File liens
Request asset seizures

This is called judgment enforcement—and may require another legal step.

If You Lose:

You may have options:

Appeal the decision to a higher court
Request reconsideration
Settle the judgment over time (payment plans)

An appeal must usually be filed within 30 days—and must show a legal error (not just disagreement with the result).

IV. Common Mistakes to Avoid

✅ Filing in the wrong court
✅ Using the wrong names or addresses
✅ Missing deadlines
✅ Incomplete or sloppy paperwork
✅ Failing to serve properly
✅ Ignoring court notices
✅ Being unprepared for trial

These errors can delay or ruin your case. If the matter is serious, get legal advice before proceeding.

V. Can I File Without a Lawyer?

Yes—this is called pro se representation (representing yourself). It’s allowed in:

Small claims court
Most civil courts

But here’s the truth:

Small claims = okay alone
Complex cases = get a lawyer

A good lawyer increases your chances of success, especially when the other side has legal counsel.
