About This Calculator
This calculator finds your exact filing deadline for a medical malpractice claim in Arizona. It applies Arizona's specific statute of limitations period, checks whether the discovery rule extends your deadline, accounts for tolling if the injured party was a minor, and flags any special notice requirements if your claim involves a government entity. Enter your incident date — or discovery date if the harm wasn't immediately apparent — and the calculator counts forward using Arizona's exact rule to show your filing deadline, the time remaining, and an urgency status. Results are based on verified state statute citations, not general estimates.

How Arizona's Medical Malpractice Deadline Works
Under Arizona Rev. Stat. § 56, Arizona provides 2 years to file a medical malpractice lawsuit. The clock typically begins when the injury was discovered — or when it reasonably should have been discovered — rather than on the date the harm occurred. This is known as the discovery rule. Arizona extends the filing window by up to 1 additional year under the discovery rule.
Arizona's medical malpractice statute of limitations is governed by the state's civil procedure and limitations statutes. Claims against government-owned hospitals or healthcare facilities in Arizona are subject to the applicable government tort claims act in addition to the standard medical malpractice procedural requirements. Under state law, the limitations period is tolled for minor claimants until they reach the age of majority at 18.
Special Circumstances
Government entity claims: If the defendant is a government entity, Arizona requires a formal administrative claim notice to be filed within 6 months of the incident before a lawsuit may be filed. Missing this notice deadline permanently bars the claim. After the claim is rejected, you have 12 months to file suit.
Minor claimants: If the injured person was a minor at the time of the incident, Arizona tolls the statute of limitations until they reach age 18.
What Happens If You Miss the Deadline
If a lawsuit is filed after the statute of limitations expires, the defendant can ask the court to dismiss the case as time-barred — and courts almost always grant this motion, regardless of how strong the underlying claim is. The right to sue is lost permanently; there is no general exception for not knowing the deadline existed. A small number of circumstances can pause or extend the clock, covered in the Special Circumstances section above if they apply to your claim type and state. If your deadline is approaching or may have already passed, contact a licensed attorney immediately — some exceptions are themselves time-sensitive.
Frequently Asked Questions
When does the clock start for a medical malpractice claim in Arizona?
Arizona law triggers the medical malpractice deadline when the patient discovers, or through the use of reasonable diligence should have discovered, both the injury and its causal connection to the medical treatment. This specific discovery rule acknowledges that clinical negligence is often difficult for a layperson to identify immediately. Prompt investigation is necessary once any unexpected medical complication arises.
Does Arizona enforce a statute of repose for medical malpractice?
Yes, Arizona courts and statutes recognize a strict statute of repose that acts as an ultimate deadline for medical malpractice claims. This repose period begins on the date of the negligent act and absolutely extinguishes the right to sue once the period expires. The harsh reality of repose means a claim can die before the patient even knows they were harmed.
What are the rules for minor tolling in Arizona medical malpractice cases?
Arizona generally tolls the medical malpractice statute of limitations for injured minors until they reach the age of eighteen. The standard filing timeframe begins to run once the minor achieves adulthood, allowing them to initiate litigation independently. Nonetheless, parents are encouraged to file earlier to preserve crucial medical evidence and witness testimony.
Does Arizona require a pre-suit expert affidavit for medical negligence?
Arizona requires plaintiffs pursuing a medical malpractice lawsuit to serve a preliminary expert opinion affidavit shortly after filing the complaint. This affidavit must be signed by a qualified medical professional confirming that the defendant breached the standard of care. Failing to timely serve this expert certification will generally result in the court dismissing the lawsuit.
Are there special notice requirements for suing a public hospital in Arizona?
Yes, suing a government-owned healthcare facility or a publicly employed physician in Arizona requires strict compliance with the state's Notice of Claim statute. A formal administrative notice must be filed very shortly after the injury accrues, acting as a mandatory prerequisite to litigation. Missing this highly accelerated notice deadline permanently bars the medical malpractice claim.
