If some time has passed since your accident, you may be wondering, how long do I have to file a personal injury claim in Arizona? Maybe you thought your injuries would get better. Maybe you were focused on doctors, physical therapy, work, or taking care of your family. Or maybe you dealt with the insurance company yourself and are now wondering if you should have talked to a lawyer sooner.
You are not alone.
In most Arizona personal injury cases, you generally have two years from when the claim accrues to file a lawsuit. Arizona law sets this general deadline under A.R.S. § 12-542.
But that does not mean every injury claim gives you two full years. Some cases have shorter deadlines, and special circumstances can affect when the clock starts.
If you were injured in Phoenix, Mesa, Chandler, Tempe, Scottsdale, Queen Creek, or another community in the Phoenix metro area, understanding your deadline can help you determine whether it is still worth pursuing your case.
How Long Do I Have to File a Personal Injury Claim in Arizona?
For most personal injury cases, Arizona law gives you two years after your cause of action accrues to file a lawsuit. A.R.S. § 12-542 covers injuries to a person, including many common negligence-based personal injury claims.
For a typical car accident, this usually means the two-year period starts around the date of the accident and injury.
For example, imagine you were injured in a car accident in Phoenix on September 1, 2025. If the standard two-year deadline applies to your case, you would generally need to file your lawsuit by September 1, 2027.
That may sound like a long time.
But two years can go quickly when you are dealing with a serious injury.
You may spend months going to doctors and specialists. You may be waiting to see whether surgery is necessary. You may be missing work or trying to return to your job. At the same time, you could be dealing with insurance adjusters who want to settle your claim.
Before you know it, months or even a year may have passed.
That is why it is better to find out your deadline early rather than assuming you have plenty of time.
Is It Too Late to File a Personal Injury Claim?
This is one of the most important questions an attorney can help you answer.
If your accident happened several months ago, it may not be too late. Even if it happened more than a year ago, you may still have time under Arizona’s general two-year rule.
The important thing is to determine the actual deadline for your specific case.
For example, someone injured in a car accident 18 months ago may still have a viable claim. Someone injured 25 months ago may face a very different situation. However, the date of the accident is not always the only fact that matters.
There are exceptions and special rules that can affect when a claim accrues and how long you have to take legal action.
That is why you should not automatically assume that your case is over simply because some time has passed.
If you are asking yourself, “Can I still sue after an accident?”, it is worth having your situation reviewed before deciding that it is too late.
What Is the Arizona Personal Injury Statute of Limitations?
You may hear lawyers refer to the Arizona personal injury statute of limitations.
That is simply the legal term for the deadline that limits how long you have to file a lawsuit.
For most personal injury cases, the general statute of limitations is two years. Arizona’s law says an action for an injury to another person generally must be commenced within two years after the cause of action accrues.
The important word is “accrues.”
That is because the legal deadline is not always as simple as counting two years from the date printed on an accident report. In many straightforward cases, the accident and the injury happen at the same time. But other situations can be more complicated.
For example, some injuries may not be immediately apparent. Arizona recognizes circumstances where the discovery rule can affect when the limitations period begins. Under this rule, the clock may depend on when the injured person discovered, or reasonably should have discovered, the injury and its cause.
You should not assume that the discovery rule automatically gives you more time. Whether it applies depends on the facts of the case.
What If My Accident Happened More Than Two Years Ago?
If more than two years have passed since your accident, you should not assume that you automatically have no legal options.
At the same time, you should not assume that an exception will save your case.
Arizona has specific rules that can change how a deadline is calculated in certain circumstances. Legal disabilities, including some situations involving minors, can affect when the statute of limitations begins to run. Arizona law also provides specific rules for certain claims involving criminal conduct.
There are also different deadlines for certain types of claims.
This is why the answer to “Is it too late?” cannot always be determined by simply looking at the calendar.
If you were injured more than two years ago, the best thing you can do is have an Arizona personal injury attorney review the dates and circumstances of your case. You may find out that the deadline has passed. You may also discover that a different rule applies.
Either way, knowing where you stand is better than guessing.
Some Personal Injury Claims Have Shorter Deadlines
One of the biggest mistakes people make is assuming every Arizona injury case has the same two-year deadline.
It does not.
Claims Against the Government
If your injury involves a government entity or government employee, you may have significantly less time to act.
Arizona law generally requires lawsuits against a public entity or public employee to be brought within one year after the cause of action accrues.
There is also a separate 180-day notice-of-claim requirement. A person with a claim against a public entity, public school, or public employee generally must file the required notice within 180 days after the claim accrues. Missing that deadline can prevent the claim from being pursued.
This can become important after an accident involving a city vehicle, county vehicle, public school, government employee, or other public entity.
For example, if you were injured in an accident involving a City of Phoenix vehicle, you should not assume you have two years to figure things out.
The shorter deadlines make getting legal advice quickly especially important.
Dog Bite Claims
Dog bite cases can also involve different deadlines.
Arizona has a specific statute imposing liability on a dog owner when the dog bites someone who is lawfully in a public or private place.
According to current Arizona law, a claim based on the state’s statutory dog-bite liability can have a one-year deadline, although a negligence claim may be subject to a different limitations period.
This is another example of why you should not simply assume that every injury gives you two years.
If you were bitten by a dog in Phoenix or the surrounding area, it is worth having the claim evaluated promptly.

Does Talking to the Insurance Company Extend My Deadline?
No. This is an important distinction.
There is a difference between making an insurance claim and filing a lawsuit.
Simply negotiating with an insurance company does not necessarily protect your right to file a lawsuit. Arizona courts have addressed the importance of properly commencing an action before the applicable statute of limitations expires. See this Arizona Court of Appeals decision published by FindLaw.
After a car accident, you may report the accident to the insurance company and spend months negotiating with an adjuster. You may exchange medical records, bills, photographs, and other information. The insurance company may even make a settlement offer.
But those conversations do not automatically mean your lawsuit deadline has been extended.
Arizona courts have recognized that filing the lawsuit itself is critical to commencing an action for purposes of the statute of limitations.
This means you should not assume that an active insurance claim protects you indefinitely.
If the insurance company keeps asking for more information while your deadline approaches, talk to an attorney before assuming everything is being handled.
You can learn more about this issue in our article on whether you should tell your insurance company you were in an accident.
Why Should I Contact a Lawyer If I Still Have Time?
You might be thinking, “If I have two years, why do I need to talk to a lawyer now?”
Because the deadline is only one part of your case.
Evidence can become harder to find as time passes. Security camera footage may be erased. Vehicles may be repaired or sold. Witnesses may forget important details. Medical records can become more difficult to organize, and memories of exactly what happened can fade.
Waiting can also make it harder to understand the full impact of your injuries.
A serious injury may affect your ability to work, care for your children, exercise, sleep, or enjoy activities you once took for granted. Some injuries require ongoing treatment or may result in permanent limitations.
You do not necessarily know the full extent of those damages immediately after an accident.
An attorney can begin investigating the claim while the evidence is still available and help you understand what your case may involve.
What If I Was Partially at Fault for the Accident?
Another reason people delay contacting a lawyer is that they believe they may have caused part of the accident.
Being partially at fault does not necessarily mean you cannot pursue compensation.
Arizona follows a comparative fault system, which means fault can be allocated among the parties involved. Your potential recovery can be reduced based on your percentage of fault.
So if an insurance company tells you that you were partly responsible, that does not automatically mean you have no case.
The details matter.
The same is true if the other driver’s insurance company has already denied your claim or argues that your injuries were caused by something else. A lawyer can look at the evidence and help you understand whether the insurer’s position is supported by the facts.
What Should I Do If I Think My Deadline Is Approaching?
Do not wait for the last week or last month.
If you are asking how long do I have to file a personal injury claim in Arizona, gather the basic information you have about your accident and speak with an attorney.
Start with the date and location of the accident. Gather your accident or police report, medical records and bills, insurance information, photographs, correspondence with insurance companies, and information about any witnesses.
You do not need to organize everything perfectly before calling a lawyer.
If the accident happened in Phoenix, Mesa, Chandler, Tempe, Scottsdale, Queen Creek, or another part of the Valley, a local personal injury attorney can review the circumstances and help determine which Arizona deadlines may apply.
The sooner you know your deadline, the more options you may have.
Don’t Assume It’s Too Late Until You Ask
If you have been asking yourself, “Is it too late to file a personal injury claim?”, do not make that decision based only on how much time has passed.
For many Arizona personal injury cases, the general deadline is two years. But different rules can apply depending on the type of injury, who caused it, when the claim accrued, and whether a government entity or another special circumstance is involved.
If your accident happened recently, there is no reason to wait.
If it happened months ago, you may still have time.
And if it happened more than two years ago, it may still be worth having an attorney look at the specific facts before you assume you have no options.
At Catastrophic Injury Attorneys, we understand that contacting a lawyer may not have been your first priority after an accident. You may have been focused on getting better, taking care of your family, and trying to get your life back to normal.
You do not have to figure out the legal deadline alone.
