A defendant is the person, business, or entity being sued in a civil case. If you were injured by someone else's negligence in Utah, the party you hold responsible becomes the defendant in your personal injury claim. Understanding that role helps you make sense of the legal process ahead.
At Lance Bingham, our Salt Lake City personal injury team explains these terms in plain language so you always know where you stand. Whether you are considering a lawsuit or trying to understand court paperwork, knowing what a defendant is and does gives you a clearer path forward.

A defendant is the party a civil lawsuit is brought against.
In a personal injury case, the defendant is the person or company accused of causing harm through negligence. The party bringing the claim is the plaintiff.
A defendant in certain civil actions may also be called the respondent, a term usually reserved for someone responding to an appeal.
The defendant's job is to respond to the claims and defend against them. That response can take many forms, from denying the allegations to negotiating a settlement.
The defendant is whoever the lawsuit names as the responsible party. In a car crash claim, that might be the at-fault driver or their insurer. In a slip and fall claim, it could be the property owner.
At Lance Bingham, we help injured people identify every party who may share responsibility, so no liable defendant gets overlooked.
In court, the defendant sits on one side of the case caption, opposite the party bringing the action. Court documents list that party by name, such as Smith v. Jones, where Jones is often the defendant.
The label attaches the moment a formal document names the person as the party defending against the claim.


The plaintiff and the defendant are the two main parties in most cases. The plaintiff starts the action by filing a complaint. The defendant responds to it.
In a personal injury claim, the injured person is usually the plaintiff, and the party who caused the harm is the defendant. The plaintiff carries the burden of proving the claim. The defendant does not have to prove innocence; the plaintiff must prove the case.
| Feature | Plaintiff | Defendant |
| Role in the case | Starts the lawsuit | Responds to the lawsuit |
| Who they are | The party claiming harm | The party accused of causing harm |
| Main task | Prove the claim | Defend against the claim |
| Burden of proof | Carries the burden | Does not carry the burden |
| Remedy sought | Compensation or a court order | To reduce or avoid liability |
In a Utah injury claim, the defendant is the negligent party you seek compensation from. That party is often backed by an insurance company with its own attorneys.
Because the insurer works to limit what it pays, having your own advocate matters. Our Lance Bingham attorneys build your claim and deal directly with the defendant's insurer. Call 801-477-8219 to talk through your case for free.
A defendant in a personal injury case is any party accused of causing harm through negligence. That can be an individual, but it is often a business, a driver, or an insurer standing behind them.
More than one defendant can be named in the same case. When several parties share fault, each may be held responsible for their portion of the harm. Identifying every liable defendant is one of the most important early steps in a claim.
| Type of Defendant | Common Example |
| At-fault driver | The negligent driver in a car or truck crash |
| Property owner | The owner of a store or building in a slip and fall |
| Business or employer | A company whose employee caused the harm on the job |
| Product maker | A manufacturer of a dangerous or defective product |
| Government entity | A manufacturer of a dangerous or defective product |
An individual defendant is a single person accused of causing your injury. This is common in car crashes, dog bites, and pedestrian accidents.
Even when the defendant is one person, their insurance company usually handles the claim and pays any compensation owed.
A business defendant is a company accused of causing harm. Examples include a store where a fall happened or a trucking company whose driver caused a crash.
Corporate defendants often have significant legal and insurance resources, which is why injured people benefit from having their own advocate.
Every defendant in a civil case has rights that protect fairness in the process. Knowing these rights also helps injured plaintiffs understand how the other side will respond to a claim.
Core rights and responsibilities include:
A defendant who ignores these responsibilities can lose important protections. That is why an injured plaintiff who files correctly and on time holds a real advantage.
Ignoring a lawsuit is the costliest mistake a defendant can make. If a defendant fails to respond within the deadline, the plaintiff can ask the court for a default judgment. A default judgment means the defendant loses the chance to contest the claim. The court can then award the plaintiff what they requested without a full hearing.
Once you file an injury claim, the defendant follows a defined process under Utah law. Knowing these steps helps you understand what to expect after your case begins.
The general path looks like this:

Timing controls much of what happens in a Utah case. Under Utah Rule of Civil Procedure 12(a)(1), a defendant generally must file and serve an answer within 21 days after being served within the state, or within 30 days if served outside Utah.
Deadlines also limit how long an injured person has to file in the first place. Missing the filing window can bar the claim entirely, no matter how strong the facts are.
Several Utah laws shape the deadlines that apply when you bring an injury claim against a defendant. Understanding them helps you act in time and protect your right to compensation.
The following laws come up most often in Utah injury matters:
These deadlines move quickly. Our Lance Bingham attorneys track every applicable date so your Utah claim stays valid.
No. Being named a defendant means a party is accused of causing harm. The plaintiff must still prove the defendant's negligence to recover compensation.
Yes. A defendant can file a counterclaim against the plaintiff. That makes the defendant a plaintiff on the counterclaim within the same case.
A co-defendant is one of two or more defendants named in the same case. Each co-defendant may share responsibility for the alleged harm.
The defendant is the party accused of causing the injury, such as an at-fault driver or a property owner. That party is often backed by an insurer.

Understanding what a defendant is helps you feel more confident about the legal road ahead. If someone else's negligence left you injured in Utah, the responsible party is the defendant in your claim, and you do not have to face their insurer alone.
