Defendant

A defendant is the person or party you file a personal injury claim against after an accident. In Arizona, correctly identifying that party is one of the most important steps in seeking compensation. Name the wrong person, miss one who shares fault, or file too late, and your recovery can shrink or disappear entirely.

At Hartley Law Car Accident & Injury Lawyers, our Arizona personal injury attorneys focus on holding at-fault parties accountable and pursuing full compensation for injured people. Naming the right at-fault party requires quick action and precise evidence.

What Does "Defendant" Mean in a Personal Injury Case?

In a personal injury case, the defendant is the party accused of causing your injuries through negligence or wrongful conduct. This is the person, business, or entity you hold legally responsible for your losses. The defendant is who your claim, and any lawsuit that follows, is filed against.

The defendant sits on the opposite side of the injured person who brings the claim. Their role is to respond to the allegations, dispute liability where they can, and limit what they may owe. In most injury claims, the defendant's insurance company defends them and pays any settlement or judgment.

A defendant is not automatically guilty of anything. The label simply identifies the party a claim is brought against. Whether that party is actually at fault, and to what degree, is decided through negotiation or, if needed, in court.

Plaintiff vs. Defendant: Who Is Who in Your Claim?

Every civil injury lawsuit has two core sides, and the difference between plaintiff and defendant is straightforward once you see the roles side by side. The plaintiff is the injured person seeking compensation. The defendant is the party accused of causing the harm.

Here are the two roles that anchor a personal injury claim:

• Plaintiff: The injured person who files the claim or lawsuit and carries the burden of proving the defendant's fault and the extent of the damages.
• Defendant: The party accused of causing the injury, who responds to the claim, may raise defenses, and can be ordered to pay compensation if found liable.

Knowing which side you are on shapes what you must prove and what the other party will try to argue. As the injured person, you are the plaintiff, and we build your case to establish the defendant's responsibility.

Identifying the Right Defendant in Your Injury Claim

The at-fault party is not always the obvious one. A car crash may look like a simple driver-versus-driver dispute, yet the correct defendant could be an employer, a vehicle manufacturer, or a government agency. Getting this right early protects your claim.

Consider a delivery driver who runs a red light while working. The driver is one possible defendant, but the company that employs them may also be liable. Naming both parties can be the difference between partial and full compensation.

Several types of parties can become defendants in an injury case:

• At-fault drivers in car, truck, or motorcycle collisions.
• Employers whose workers cause harm on the job.
• Property owners who fail to fix or warn about hazards.
• Product manufacturers whose defective goods cause injury.
• Government entities responsible for unsafe roads or public property.

Each potential defendant carries different rules, deadlines, and insurance coverage. We investigate every source of liability so no responsible party escapes accountability.

When There Is More Than One Defendant

Many accidents involve several parties who each share part of the blame. State law addresses this through A.R.S. § 12-2506, which requires fault to be allocated among all responsible parties. Each defendant is generally liable only for their own percentage of fault, not the entire amount.

This system, known as several liability, means the total fault assigned to everyone involved must add up to one hundred percent. Suppose two drivers and a road-maintenance contractor all contributed to your injuries. Each would be responsible for their assigned share, so identifying every defendant directly affects how much you can recover.

When the Defendant Is a Government Entity

Pursuing a claim against a city, county, or state agency follows a stricter timeline than a claim against a private party. Under A.R.S. § 12-821.01, you must file a formal notice of claim with the correct public entity within one hundred eighty days of the injury. Missing that deadline can end your case before a lawsuit is ever filed.

The notice of claim must describe the incident and state a specific settlement amount. Because these rules are unforgiving, we act quickly when a public defendant is involved.

How State Fault Rules Affect the Defendant's Liability

Arizona follows a pure comparative negligence rule under A.R.S. § 12-2505. Under this rule, your compensation is reduced by your own percentage of fault, but you are never barred from recovering, even if you were mostly to blame. This is one of the more injured-person-friendly systems in the country.

Here is how it works in practice. If your total damages are one hundred thousand dollars and a jury finds you thirty percent at fault, the defendant is responsible for seventy thousand dollars. The reduction reflects your share of the fault, not a cap on your right to recover.

Insurance companies know this rule and use it against you. Adjusters often inflate the injured person's share of fault to lower what the defendant must pay. We push back on those percentage arguments with evidence, documentation, and, when needed, expert testimony.

The Deadline to Name a Defendant in Arizona

Time is a hard limit in every injury case. Under A.R.S. § 12-542, you generally have two years from the date of the injury to file a personal injury or wrongful death lawsuit against a private defendant. Once that window closes, the court will almost always dismiss the case.

The clock usually starts on the day of the accident. In some situations, the state's discovery rule delays the start until you knew, or reasonably should have known, that you were injured. These exceptions are narrow and fact-specific, so they should never be assumed.

Waiting also weakens a case even when the deadline has not passed. Evidence fades, witnesses forget, and records disappear. Acting early lets us preserve proof and build the strongest possible claim against the defendant.

How We Build a Case Against the Defendant

Holding a defendant accountable takes more than filing paperwork. It requires a methodical effort to prove fault, document your losses, and counter the defense's arguments at every turn.

We follow a clear process to build your case:

• Investigate the accident. We gather police reports, photographs, video footage, and witness statements to establish what happened.
• Identify every liable party. We trace fault beyond the obvious defendant to employers, contractors, or other responsible parties.
• Document your damages. We compile medical records, bills, and proof of lost income to show the full extent of your losses.
• Confront the insurer. We negotiate directly with the defendant's insurance company and reject lowball offers.
• Prepare for trial. We build every case as if it will go before a jury, which strengthens our position in settlement talks.

This groundwork gives you leverage. When a defendant and their insurer see a well-documented case, they are far more likely to offer fair compensation.

Frequently Asked Questions About Personal Injury Defendants

Can there be more than one defendant in a single injury case?

Yes, many accidents involve multiple at-fault parties, and state law under A.R.S. § 12-2506 assigns each defendant a percentage of fault. We identify every responsible party to protect your full recovery.

What happens if the defendant was mostly at fault but I was partly to blame?

Under the state's pure comparative negligence rule, you can still recover even if you share fault. Your compensation is reduced by your percentage of blame, not eliminated.

Who is the defendant if a company employee caused my accident?

Both the employee and their employer may be defendants. When a worker causes harm while doing their job, the employer can be held liable, which often expands the available insurance coverage.

How long do I have to file a lawsuit against a defendant?

Under A.R.S. § 12-542, you generally have two years from the date of injury to file a lawsuit against a private defendant. Missing this deadline usually means losing your right to compensation.

What if the defendant is a city or state agency?

Claims against government defendants require a formal notice of claim within one hundred eighty days under A.R.S. § 12-821.01. This deadline is much shorter than the standard two-year limit, so quick action matters.

Is the defendant the same as the insurance company?

No, the defendant is the at-fault party, while their insurer typically defends the claim and pays any settlement. You pursue the defendant, but you often negotiate with the insurance company.
