If you’ve been injured due to someone else’s negligence, knowing how to file a personal injury lawsuit is critical for your recovery.

Arizona’s statute of limitations generally gives you two years from the date of your injury to file a personal injury claim. Missing this deadline could prevent you from recovering compensation, regardless of how strong your claim may be.

At Zanes Law, we’ve helped injury victims across Arizona navigate the legal process and pursue the compensation they deserve for over 20 years. This guide explains how to file a personal injury lawsuit in Arizona so you can protect your rights and take action before important deadlines pass.

What Is a Personal Injury Claim in Arizona?

A personal injury claim is a request for financial compensation after you’ve been injured because someone else acted negligently or recklessly. This may include compensation for medical bills, lost income, pain and suffering, and other damages.

Most personal injury cases begin with an insurance claim. If the insurance company refuses to pay a fair settlement, your attorney may choose to file a civil lawsuit.

Arizona’s pure comparative fault rule means you may still recover compensation even if you were partly responsible for the accident. Your recovery is simply reduced by your percentage of fault. For example, if you’re awarded $100,000 but found to be 20% responsible, you could still recover $80,000.

What Types of Injuries and Cases Qualify?

Some of the most common types of personal injury claims include:

• Car accidents and auto accident injury
• Slip and fall accidents
• Motorcycle accidents
• Wrongful death claims

If your injury involved a government agency or government vehicle, Arizona generally requires a Notice of Claim within 180 days before you can pursue a lawsuit.

How Is a Lawsuit Different from an Insurance Claim?

An insurance claim is filed directly with the at-fault party’s insurance company. A lawsuit is a formal legal action filed in court. Many injury cases settle before trial, but filing a lawsuit sometimes encourages insurers to make a more reasonable settlement offer.

How to File a Personal Injury Lawsuit in Arizona — Step by Step

Filing a personal injury lawsuit may seem overwhelming. However, understanding what happens at each stage can help you protect your rights, avoid common mistakes, and make informed decisions as your case moves forward.

Here’s how to file a personal injury claim:

Step 1 — Seek Medical Treatment and Document Everything

Your health comes first. Even if your injuries seem minor, see a doctor as soon as possible. Waiting to get treatment allows insurance companies to argue that your injuries weren’t serious or weren’t caused by the accident.

Keep copies of:

• Medical records and bills
• Photos of your injuries and the accident scene
• Witness names and contact information
• Pay stubs showing lost wages
• Notes about your pain, recovery, and daily limitations

Strong documentation can make a significant difference when negotiating a settlement or presenting your case in court.

Step 2 — File a Claim with the Insurance Company First

Before filing a lawsuit, most plaintiffs send a demand letter to the at-fault party’s insurer.

A demand package typically includes:

• A summary of what happened
• Medical records and expenses
• Lost wage documentation
• A request for compensation

If the insurer denies the claim, underpays, or refuses to negotiate in good faith, filing a lawsuit is the next step. A trusted personal injury attorney knows how insurers evaluate and pay out claims and will build a strong case on your behalf.

Step 3 — File Your Complaint in the Correct Arizona Court

If settlement negotiations don’t resolve your claim, the next step is filing a complaint with the appropriate Arizona court. Claims under $10,000 are typically filed in Justice Court, while claims over $10,000, including most personal injury lawsuits, are filed in the Arizona Superior Court.

The complaint must name the defendant(s), state the factual basis for the claim, and specify the damages and compensation you’re seeking. After filing, the defendant must be formally served under the Arizona Rules of Civil Procedure Rule 4.

Step 4 — Discovery, Negotiation, and Trial

Once the lawsuit is filed, each party exchanges evidence, requests documents, answers written questions, and may participate in depositions.

This phase typically lasts 6–12 months in the Arizona Superior Court. Most Arizona personal injury cases settle during or after discovery, as the act of filing often prompts the insurer to make a more serious offer.

If no settlement is reached, the case proceeds to trial, where a jury determines liability and damages under Arizona’s comparative fault rules (A.R.S. § 12-2505).

Arizona’s Statute of Limitations — Your Deadline to File

One of the most important parts of learning how to file a personal injury lawsuit in Arizona is understanding the filing deadline. In most cases, you have two years from the date of your injury to file a claim. However, the actual timeline may depend on the case type:

What Happens If You Miss the Deadline?

If you file your lawsuit after the statute of limitations expires, the court will likely dismiss your case. Even if your injuries are serious and the evidence is strong, you may lose the ability to recover compensation.

In some situations, Arizona’s discovery rule may extend the deadline if an injury could not reasonably have been discovered right away. However, these exceptions are narrow, so it’s best not to rely on them.

When Should You Contact an Attorney?

It’s best to contact a personal injury attorney as soon as possible after an accident, as important evidence can disappear quickly. Surveillance footage may be overwritten, witnesses’ memories can fade, and physical evidence may be lost.

An attorney can also help preserve critical evidence by sending a spoliation letter. This is a formal request requiring the responsible party to retain relevant evidence that could otherwise be destroyed or discarded.

If you’re unsure which filing deadlines apply to your case, Zanes Law offers free consultations to help you understand your legal options.

Common Mistakes That Can Hurt Your Arizona Personal Injury Case

Knowing how to file a personal injury lawsuit is important. However, avoiding a few common mistakes can also make a difference in the outcome of your case.

• Missing important deadlines. Arizona’s filing deadlines are strict. If your case involves a government agency, you may have only 180 days to file a Notice of Claim. Missing these deadlines can prevent you from recovering compensation.
• Accepting the first settlement offer. Insurance companies often make quick offers before the full extent of your injuries is known. Accepting an early settlement usually means giving up the right to seek additional compensation later.
• Posting on social media. Insurance adjusters and defense attorneys may review your social media accounts for photos or posts they can use to question your injuries. Even innocent posts can be taken out of context.
• Waiting too long to hire an attorney. Evidence doesn’t last forever. Surveillance footage may be deleted, witnesses become harder to contact, and important records can be more difficult to obtain as time passes.
• Assuming you can’t recover because you were partly at fault. Arizona’s pure comparative fault law allows many injured people to recover compensation even if they share some responsibility for the accident. Your recovery is simply reduced by your percentage of fault.
