Accidents can happen quickly, but their impact can last much longer. If you’re facing pain, rising bills, or lost income due to someone else’s negligence or a defective product, Arizona law lets you pursue a personal injury claim—but only for a limited time.

Phoenix’s statute of limitations sets a firm deadline to file. If you miss it, your case may never be heard, no matter how strong your evidence is. Knowing your legal timeline is key to protecting your rights and recovering what you’ve lost. 

What Is the Statute of Limitations for Personal Injury in Arizona?

Under Arizona Revised Statutes § 12-542, injury victims typically have two years from the date of the injury to file a lawsuit in civil court. This applies to most accident-related incidents, including:

  • Car accident claims
  • Slip and fall or trip and fall injuries
  • Construction or workplace injuries caused by third-party negligence
  • Product liability cases involving dangerous or defective items
  • Dog bites and other animal-related injuries
  • Claims involving both negligence and strict liability theories

This statutory period begins on the date the injury occurs. For example, if you were rear-ended at a red light and suffered whiplash, your two-year window starts that day. It does not matter if you filed an insurance claim, negotiated with the other party, or expected a quick settlement. Once the two-year mark passes, your right to file an accident lawsuit may be permanently lost.

It is also crucial to understand that this deadline applies to court filings, not insurance claims. While it is common to start with an insurance claim, the legal clock does not pause while you negotiate. If you have not filed in court by the two-year mark, your case can be dismissed when you eventually do file a lawsuit.

Every day you wait to take action puts your claim at risk. An experienced Phoenix personal injury attorney can help you confirm your timeline and begin the filing process before it is too late. 

Exceptions to Arizona’s Two-Year Rule

While the two-year filing period is standard, Arizona law recognizes specific exceptions that may extend—or “toll”—that window. These exceptions apply in certain circumstances, such as when an injury isn’t discovered right away or when the person harmed is legally unable to act.

  • The Discovery Rule: In some cases, injuries are not immediately apparent, and the discovery rule allows the statute of limitations to begin when you discover—or reasonably should have discovered—the harm. This rule often applies to situations like defective medical devices, toxic exposure, or delayed symptoms, meaning the clock may start at the time of diagnosis rather than on the date of the original incident.
  • Injury Victims Who Are Minors: In Arizona, kids have extra time to file a personal injury claim. The countdown to take legal action doesn’t start until they turn 18, and then they have two years to file a claim. This rule is particularly helpful in cases such as car accidents, playground injuries, or the use of dangerous toys. If a parent or guardian files a claim earlier, the usual timeline applies. But if they don’t, the law gives the child more time once they’re old enough.
  • Mental Incapacity: If the injury victim is mentally incapacitated—whether temporarily or permanently—the statutory clock pauses until they regain legal capacity. This can occur in cases involving brain injuries, coma, or cognitive disability resulting from the incident.
  • Claims Against Government Entities: If your claim involves a city, county, or state agency—such as a fall on public property or a collision with a government vehicle—you must act much faster. Arizona law requires that you file a formal notice of claim within 180 days of the incident. After that, you must file your lawsuit within one year.

These shortened deadlines apply whether your claim involves a negligence claim or a strict liability situation. Failing to file your notice on time can result in the loss of your right to pursue legal action altogether. 

Why Timing Matters in Phoenix Personal Injury Cases

The longer you wait to begin the legal process, the more difficult it becomes to build a strong case. Time can weaken your position in several key ways:

  • Evidence Disappears: Physical evidence—such as vehicle damage, skid marks, or broken stairs—can disappear quickly. Security footage may be erased, and maintenance logs might be updated. The sooner you begin working with a lawyer, the better chance you have at preserving these details.
  • Witness Memories Fade: Eyewitnesses are critical to many personal injury cases. Their accounts help establish what happened and who was at fault. But memories fade over time, and people move or become harder to contact. Acting early allows your attorney to get statements while the events are still fresh.
  • Insurance Negotiations Can Stall: Insurance companies may attempt to run out the clock by delaying, denying, or lowballing your claim if they are aware that the deadline to file is approaching. Even ongoing negotiations with an adjuster do not stop the statute of limitations from running. Once that window closes, you lose your leverage against the insurer.
  • Comparative Fault and Legal Strategy: Arizona uses a pure comparative fault system. This means your compensation may be reduced based on your share of responsibility for the incident. The earlier your attorney begins gathering evidence and building your claim, the better your odds of minimizing your percentage of fault and maximizing your recovery.

Every injury case needs careful legal planning, and starting early gives your lawyer time to investigate and build the right strategy. While many claims involve negligence, others—such as those involving dangerous products or animals—may rely on strict liability laws.
