As a personal injury lawyer, this is one of the most often questions I am asked.
Under Arizona law, the typical statute of limitations for a wrongful death claim (I.e. Car accident) is two years from the date of the accident.
However, there are MANY exceptions.
If an intentional act, it could be one year.
If a claim against a city, county or state employee, it could be as little as 180 days. NOT six months--180 days.
If a claim against the federal government, two years to start the process.
If a medical malpractice claim, two years from the date you reasonably learn of the malpractice.
If the injured is a minor, maybe until their 18th birthday plus 6months, 1 year, two years or more.
Determining a statute of limitations for your case can sometimes be very difficult. Guessing is NOT a good idea, because if you guess wrong, you lose. Your case is over forever.
This is not a determination you should leave to anyone but an experienced person injury attorney. Experience is the key here.
These matters can sometimes be difficult for the most seasoned attorneys.
Don't wait---you may be too late to do anything.
