A plaintiff is the person or party who files a civil lawsuit and asks the court for relief. In a Florida personal injury case, the plaintiff is the injured person, or someone who sues for them, and the plaintiff carries the burden of proving the case. The person being sued is the defendant.

What is a plaintiff?

A plaintiff is the party who starts a civil lawsuit. The plaintiff files a complaint, which tells the court what happened, what law the defendant violated, and what the plaintiff wants. The plaintiff is usually listed first in the case name, as in Plaintiff v. Defendant.

Three things come with the title. The plaintiff chooses to sue, so the plaintiff controls whether and when the case begins. The plaintiff has the burden of proof, which means the plaintiff must prove the claim. And the plaintiff is the party asking for a remedy, most often money damages in an injury case.

What is the difference between a plaintiff and a defendant?

The plaintiff brings the lawsuit, and the defendant is the one being sued. The plaintiff alleges that the defendant caused harm. The defendant responds, denies, raises defenses, and can ask the court to dismiss the case.

In a car accident case, the injured driver is the plaintiff and the at-fault driver, or that driver's insurer or employer, is the defendant. In a slip and fall, the injured visitor is the plaintiff and the property owner is the defendant. A person can be a plaintiff in one case and a defendant in another, and in a single case a defendant can also file a counterclaim and become a plaintiff on that claim.

How does someone become a plaintiff in Florida?

Someone becomes a plaintiff by filing a complaint in court. Under Florida Rule of Civil Procedure 1.050, a civil action is generally commenced when the complaint is filed. The defendant is then formally served with a summons and the complaint and must respond within the time the rules allow.

Filing is the beginning, not the end. Many injury claims are negotiated with the insurance company first, and a plaintiff files suit when negotiation fails or when a deadline forces it. The deadline is the part that catches people.

Who can be a plaintiff in Florida?

Anyone with a legal claim can be a plaintiff, but the claim must belong to the right person. Rule 1.210(a) says "every action may be prosecuted in the name of the real party in interest." Several people can join as plaintiffs when they share an interest in the subject of the case and the relief sought.

Some people sue through someone else. A personal representative, administrator, guardian, or trustee may sue in their own name without joining the people for whose benefit the action is brought. Rule 1.210(b) covers children and incapacitated adults: if a minor or incompetent person has a representative, that representative sues for them. If not, the person may sue by next friend or through a guardian ad litem, and the court appoints a guardian ad litem when no one else represents them.

Wrongful death shows the rule most clearly. Under section 768.20, Florida Statutes, the action "shall be brought by the decedent's personal representative," for the benefit of the survivors and the estate. The family members who lost the person are the beneficiaries, but the personal representative is the plaintiff of record.

What does a plaintiff have to prove?

In a Florida negligence case, the plaintiff must prove four things: the defendant owed a duty of care, the defendant breached it, the breach caused the injury, and the plaintiff suffered damages. The standard in a civil case is the greater weight of the evidence, which means the plaintiff's version is more likely true than not. That is lower than the criminal standard of beyond a reasonable doubt.

Causation and damages are where cases are won and lost. A plaintiff proves them with medical records, treating doctors, bills, photographs, witness testimony, and expert opinions. The defense answers with its own experts, its own account of fault, and, as my article on what an IME is in Florida explains, a doctor the defense chooses to examine the plaintiff.

Does the plaintiff have to be completely free of fault?

No, but the plaintiff cannot be more than half at fault. Florida moved to modified comparative negligence in 2023. Under the changes enacted that year, a plaintiff who is more than 50 percent at fault generally recovers nothing, and a plaintiff who is 50 percent or less at fault recovers damages reduced by the plaintiff's own share. The rule applies to lawsuits filed after March 24, 2023.

That makes fault the central fight in many cases. The defense will look for any way to shift percentage points onto the plaintiff, such as speed, a missed warning, a phone, or a delay in treatment. A plaintiff's statements, social media, and testimony all feed that argument.

How long does a plaintiff have to file in Florida?

For most negligence claims that accrued after March 24, 2023, a plaintiff has two years to file. The 2023 tort reform law cut the negligence limitation period in section 95.11, Florida Statutes, from four years to two. Claims that accrued before that date generally keep the earlier period. Wrongful death and other claim types have their own rules, and some defendants, such as government entities, require notice before suit.

Miss the deadline and the case can be dismissed no matter how strong it is. This is the single most important date in the case, and it is why I tell people to see a lawyer early. Do not wait for the insurance company to finish talking.

What are a plaintiff's responsibilities?

A plaintiff must tell the truth, preserve evidence, answer discovery, and cooperate with the case. Once you sue, the other side is entitled to discovery. You answer written questions, produce records, and sit for a deposition under Rule 1.310, where you testify under oath before trial. My article on what a deposition is in Florida walks through it.

The defense may also seek a medical exam under Rule 1.360, serve subpoenas on your doctors and employers, and ask for your social media and prior records. Many of those requests are fair. Some are not, and your lawyer's job is to object to the ones that go too far. My articles on what a subpoena is in Florida and what an affidavit is in Florida cover two of the places your sworn words and records come up.

In practice, three habits protect a plaintiff. Keep treating with your doctors and follow their advice, because gaps in care become a defense argument. Stay off social media about the case, the accident, and your activities. And tell your lawyer everything, including prior injuries and prior claims, because the defense will find them.

Do you have to be a plaintiff to get paid after an accident?

No. Many injury claims settle without a lawsuit, and in those cases no one is called a plaintiff. Insurance companies pay claims every day with no complaint on file. The lawsuit is the leverage that applies when the insurer will not pay a fair amount, and it is also what protects the deadline.

Other systems use different words. An injured worker in a workers' compensation matter is usually called the claimant. A person making a PIP claim with their own auto insurer is an insured. In a criminal case, the state prosecutes and the victim is a witness, not a plaintiff. A plaintiff who loses and appeals becomes the appellant.

Frequently Asked Questions

What is a plaintiff in simple terms?

A plaintiff is the person who files a civil lawsuit. They are the one asking the court for money or other relief, and they have to prove their case.

Who is the plaintiff and who is the defendant?

The plaintiff is the party who sues, and the defendant is the party who is sued. In a car accident, the injured driver is typically the plaintiff and the at-fault driver or that driver's insurer or employer is the defendant.

Who has the burden of proof, the plaintiff or the defendant?

The plaintiff. In a Florida civil case the plaintiff must prove the claim by the greater weight of the evidence, which means it is more likely true than not.

Can more than one person be a plaintiff in a lawsuit?

Yes. Under Rule 1.210(a), people with an interest in the subject of the case and the relief sought may join as plaintiffs. Several passengers injured in one crash can sue together.

Who is the plaintiff in a wrongful death case in Florida?

The decedent's personal representative. Under section 768.20, Florida Statutes, the action is brought by the personal representative for the benefit of the survivors and the estate.

Can a child be a plaintiff in Florida?

Yes, but a child sues through a representative. Rule 1.210(b) allows a guardian or similar representative to sue for a minor, or the minor can sue by next friend or through a guardian ad litem appointed by the court.

Is the plaintiff always the injured person?

Not always. A guardian, a personal representative, or a parent suing for a child can be the named plaintiff on behalf of the injured person.

How long does a plaintiff have to file a lawsuit in Florida?

For most negligence claims that accrued after March 24, 2023, two years. Earlier claims generally keep the four-year period, and other claim types have their own deadlines, so check the date with a lawyer right away.
