Should You Sue? – Evaluate Your Case
Assessing chances of winning, time/money involved, and defendant’s ability to pay is crucial before filing a lawsuit. Determine standing by proving a direct, personal injury caused by the defendant – concrete harm like economic loss or pain. Evaluate if small claims court suits claims under state limits or if a full civil case is needed.
Here are the concrete steps to follow when suing someone.
1. Determine What You Are Suing For
The first step in bringing a lawsuit is determining what cause or causes of action you have. In other words, what are you suing for? A claim may be for personal injury, breach of contract, owed money, medical malpractice, or something else.
Even within personal injury, there are multiple grounds for compensation like:
- Negligence
- Premises liability
- Product liability
- Negligent entrustment
Once you identify the causes of action you have, you can figure out how to sue someone for car accident injuries, defamation of character, slander, or other reasons. Then, continue preparing your lawsuit.
Small Claims Court Overview
Small claims court handles disputes up to $2,500-$25,000 (varies by state) without lawyers, ideal for quick resolution of money damages. Plaintiff files a simple complaint form, pays low court fees ($30-$65), and serves the defendant via sheriff or certified mail. No attorneys allowed; judges decide based on evidence without formal discovery.
You can do small claims court without a lawyer, though a lawyer can give advice and help assess whether a claim is worth the time and money.
2. Identify Who You Are Suing
When you plan to file a legal suit, you need to know who you are suing. The party must specifically have legal liability for the cause of action. For example, if someone owes you money, you’re suing the person responsible for not paying you.
If your case is a personal injury claim, the party responsible may be an employer, manufacturer, or another driver on the road. You may name more than one defendant, but a defendant must be named to be part of the case.
3. Figure Out What Court Has Jurisdiction
Now you know who you are suing and the cause. Next, you need to know what court has jurisdiction in your case. There are multiple courts in each state, and different courts specialize in various cases.
Usually, you file the case in the court that hears that type of case, in the location where the harm occurred. Sometimes, there may be multiple options for what court can hear the case. Where you file may make a difference in what laws and procedural rules apply. In Florida, you must determine which of these courts has jurisdiction:
- Florida small claims courts are county courts that settle minor disputes valued up to $8,000. Speak with a lawyer to learn how to sue someone in small claims court.
- If your case is worth $30,000 or less, it begins in a county court.
- Circuit courts hear civil disputes valued at $30,000 or more.
Once you determine the appropriate court, you prepare the documents for filing a claim in that court.
4. Draft the Complaint
The complaint is the first paperwork you need to file to formally start a lawsuit. It summarizes the parties, the facts, the legal theories for your claim, and what you want as a remedy. The Hillsborough County court calls it a Statement of Claim.
A complaint summarizes the case. It should be accurate, thorough, and stick to the facts. Refer to the Florida Rules of Civil Procedure Rule 1.110 for information on the General Rules of Pleading.
Court Jurisdiction and Forms
Determine if small claims, county, circuit, or federal court has jurisdiction based on claim amount and location – civil cases over $30,000 go to circuit court. Fill out court forms like Civil Cover Sheet, Summons, and Complaint; filing fees range $225-$450 unless waived. Local rules may require extra forms. Make copies before plaintiff files with the clerk.

5. Complete the Filing Documents

There are other documents that you need to file with the court to begin your case, in addition to the complaint. The exact documents and the format vary from court to court.
The Hillsborough County 13th Circuit Court and the County Court require parties to submit Form 1.997 – Civil Cover Sheet. The form assists the court in keeping accurate statistics as well as appropriately managing the case in the court system. There are instructions for completing Form 1.997. The form states:
- The parties
- The division of court
- The amount of claim
- Type of case
- Remedy sought
- Jury demand
- A number of other details
You must also complete a Request for Issuance of Summons. You will need to prepare a separate request for each defendant.
Discovery and Evidence Exchange
After serving the complaint, the process of discovery begins – parties exchange evidence via interrogatories, depositions, document requests to build the case. That is why you need to gather photos, witnesses, and records early; preponderance of evidence wins civil cases. Less than 1% reach trial as most settle during this phase.
6. Submit Your Filing Documents
For Hillsborough County cases, you can e-File the case through the E-filing ePortal, or appear in person at the clerk of court. The e-portal is available for use 24/7. You should figure out if the case will go to the East Division or the Tampa division.
There is a filing fee to pay, and the amount varies based on the type of case. For a civil action exceeding $30,000 in Circuit Court, the fee is $400.00.
7. Serve the Other Party
The other party has a right to know that they are being sued. It’s up to the plaintiff to ensure that each defendant receives copies of the legal documents. Florida Rules of Civil Procedure Rule 1.070² governs the issuance of summons and who can complete service of process.
A process server must be authorized, but the court may allow a competent person who does not have an interest in the legal proceeding. The person who completes service submits a proof of service document. Each party must be served.
A summons is good for 120 days. If service isn’t complete, the court may extend the time upon good cause or neglect. They may also direct service to be completed within a certain time frame or drop the defendant as a party.
8. Proceed With the Lawsuit

Suing someone is only the beginning of the case. Just filing the legal documents does not entitle you to compensation. You need to prove your right to compensation. Once the case is filed, the defense can respond.
It’s important to take advantage of legal procedures, including discovery and motion filing, to build your case. There will be deadlines to file scheduling orders and briefs. You must complete all these steps and respond to issues raised by the defense.
