Medical Malpractice in Peoria, Arizona

By Joe Styler, editor (not an attorney). Updated October 9, 2026. Sources checked

Peoria crosses a county line. Maricopa County lists it among its cities and towns, and Yavapai County lists it among the communities in one of its supervisor districts. That gives a malpractice question here an extra layer: which county’s Superior Court?

One city, two counties

Yavapai County’s website names Peoria among the communities in its Supervisor District 1, so part of the city lies in Yavapai County. Knowing which side of that line your home sits on settles little. For a lawsuit, the statute looks first at who is being sued and where each of them lives or does business.

Which county? What A.R.S. 12-401 says

Venue, meaning the county where a lawsuit may be brought, is set by A.R.S. 12-401. Its starting rule is that no person may be sued outside the county where that person resides, unless one of the listed exceptions applies. Three of those exceptions are worth knowing:

• When several defendants live in different counties, the case may be brought in the county where any one of them resides.
• A corporation may be sued in any county where the cause of action, or part of it, arose, or where it has an agent or representative, owns property or conducts business.
• When every defendant lives outside Arizona, or their residence is unknown, the case may be brought in the county where the plaintiff resides.

Look at what the list leaves out. For an individual doctor or nurse, the statute has no general rule placing a case where the treatment happened, so care on the Yavapai side of Peoria does not by itself send a case to Prescott or Camp Verde. For a corporation, the place the claim arose is one option among several. Other exceptions exist, and choosing the county is a lawyer’s call.

The two Superior Courts, side by side

Superior Court locations in the two counties Peoria spans, as each court’s website lists them

Item	Maricopa County Superior Court	Yavapai County Superior Court
Where civil appears	The Civil department is listed at the East Court Building, 101 W Jefferson St., Phoenix	The pages we read do not say which location takes which civil cases
Other locations named	Northwest Regional Center, 14264 W Tierra Buena Ln., Surprise (listed under Family)	Yavapai County Courthouse, 120 South Cortez Street, Prescott; Superior Court, 2840 N. Commonwealth Drive, Camp Verde
Appeals go to	Division One, Arizona Court of Appeals, Phoenix	Division One, Arizona Court of Appeals, Phoenix

Maricopa lists no Superior Court facility in Peoria. These are building lists, not case assignments, and neither court’s pages say where a given lawsuit will be heard.

Peoria Fire-Medical and the city’s ambulances

The city’s fire department is Peoria Fire-Medical. The city says every fire engine carries two EMTs and two paramedics, and that over 80 percent of calls to the department are for a medical response. Since early 2017 the department has owned and operated ambulances under Certificate of Necessity number 146, issued by the Arizona Department of Health Services.

Not every ambulance in Peoria is the city’s, though. A patient needing emergency transport may get a Peoria Fire-Medical ambulance or one operated by a private company. Residents are not charged for the department’s fire or emergency medical response, but there is a charge for emergency transport, so keep any bill for the ride.

Peoria Fire-Medical is a City of Peoria department, so a complaint about its crews can be a claim against a public entity or public employee, with the shorter deadlines below. A private company’s crew differs: under A.R.S. 12-820, an independent contractor is not a public employee. Those clocks run whether or not you write to us.

Notice of claim to the City of Peoria

The city’s claims page says completed claim paperwork is filed in the Peoria City Clerk’s Office, at 8401 W. Monroe St., and its notice of claim form (revised 07/20/2011) names the City Clerk, Room 150, as the place of service.

The timing language differs. The web page says 180 days “after the incident.” The form, like A.R.S. 12-821.01, ties the 180 days to when the cause of action accrues. Under the statute, that is when the person realizes they were damaged and knows, or reasonably should know, what caused it. Pinning down that date can be hard, so let a lawyer count. A late notice is barred.

The form tells claimants to get legal advice on their own, at their own expense, and not to contact city employees for help. The statute also requires the facts behind the claim, the specific sum the city could pay to resolve it, and the facts behind that sum. A lawsuit must then follow inside one year from accrual (A.R.S. 12-821); our page on notice of claim rules for public entities explains both steps. Writing to us is not notice to the city and stops neither clock.

Records, experts and private care

In either county, records come first; see our guide to requesting your Arizona medical records. Against a health care professional, the claimant certifies whether expert testimony is needed and, if so, serves a preliminary expert opinion affidavit along with the initial disclosures. Care from a private provider generally has the two-year limit in A.R.S. 12-542, running from accrual, or from the death in a wrongful death case. Our overview of the stages of an Arizona malpractice claim puts it all in order. A form sent to us does not hold off that limit.

Peoria questions

Part of Peoria is in Yavapai County. Does my case go to a Yavapai court?

Not necessarily. A.R.S. 12-401 generally looks to the county where a defendant resides, and a corporation may also be sued where the claim arose or where it does business. Where in Peoria the care took place does not decide it alone.

Where is a notice of claim against the City of Peoria served?

The city’s form names the City Clerk, City of Peoria, Room 150. The form and A.R.S. 12-821.01 both count the 180 days from accrual of the cause of action. Sending our form does not pause that window.

Was the ambulance that took me to the hospital run by the city?

Maybe. The city says emergency transport in Peoria may come from a Peoria Fire-Medical ambulance or from one a private company operates. Which one it was can change the deadlines, so have a lawyer confirm it early. Contacting us does not pause any of them.
