To file a lawsuit in Arizona, you confirm your claim is still within its filing deadline, choose the right court for the amount at stake and the right county for venue, prepare a civil complaint and summons, submit them to the Clerk of the Court with the filing fee, and arrange formal delivery of the papers to the person or business you are suing within 90 days.
Confirm Your Deadline Before Anything Else
Every civil claim in Arizona has a statute of limitations. Once it expires, the court will almost certainly dismiss the case no matter how strong it is, so this is the first thing to check.
Personal injury, property damage, wrongful death, and conversion claims carry a two-year deadline from the date the harm occurred, or for wrongful death the date the injured person died.1Arizona Legislature. Arizona Revised Statutes 12-542 – Injury to Person; Injury When Death Ensues; Two Year Limitation Other claims run longer: written contract disputes generally allow six years, oral contracts three. Deadlines vary enough that pinning down the one that fits your specific claim is a first-week task, not a last-week one.
Suing a Government Entity Has a Much Shorter Deadline
If the defendant is an Arizona city, county, state agency, public school, or government employee, you have to file a written notice of claim with that entity within 180 days of the harm. The notice has to describe the facts, explain why the government is responsible, and state the specific dollar amount you would accept to settle. Miss that 180 days and your claim is permanently barred, even if the regular statute of limitations has not yet run.2Arizona Legislature. Arizona Revised Statutes 12-821.01 – Authorization of Claim Against Public Entity, Public School or Public Employee The entity then has 60 days to respond. If it denies the claim or stays silent, you can file suit.
Pick the Right Court
Arizona sorts civil cases by the dollar amount at stake. Filing at the wrong level can get your case tossed.
Justice Court for Claims of $10,000 or Less
Justice Courts handle civil cases where the amount in dispute, not counting interest, costs, or attorney fees, is $10,000 or less.3Arizona Legislature. Arizona Revised Statutes 22-201 – Jurisdiction of Civil Actions Within each Justice Court is a small claims division for disputes of $3,500 or less.4Arizona Judicial Branch. About Small Claims Small claims is simpler and cheaper, but attorneys generally cannot appear unless both sides agree in writing, there is no jury, and the decision cannot be appealed.
Superior Court for Claims Over $10,000
Anything above $10,000 goes to Arizona Superior Court, which has broad original jurisdiction under the state constitution.5Arizona Legislature. Arizona Revised Statutes 12-123 – Jurisdiction and Powers Superior Court is also the right place for matters Justice Courts cannot touch regardless of amount, such as real estate title disputes, probate, and requests for injunctions. Mixed cases that combine money damages with non-monetary relief typically belong in Superior Court too.
One thing to know going in: Superior Court civil cases where the amount at stake is $65,000 or less may be sent to compulsory arbitration before a judge ever hears the matter.6Arizona Legislature. Arizona Revised Statutes 12-133 – Arbitration of Claims; Agreement of Reference Either party can later reject the arbitrator’s decision and demand a trial, but the arbitration step itself is mandatory when the court determines the case qualifies.
File in the Right County
You also have to file in the right geographic location, called venue. Arizona law generally requires you to sue a defendant in the county where that person lives.7Arizona Legislature. Arizona Revised Statutes 12-401 – Venue There are exceptions: the county where a contract was to be performed, where an injury happened, or where disputed property is located can also be proper. For a business defendant, the county where it has an office or where the transaction occurred often works.
When more than one county qualifies, you choose. File in the wrong one and the defendant can move to transfer or dismiss, costing you time and money.
Prepare the Complaint and Summons
You need the full legal name and current address of every person or business you plan to sue. For a business, search the Arizona Corporation Commission’s online database to confirm the legal name and identify the registered agent authorized to accept service.8Arizona Corporation Commission. eCorp Entity Search Naming the wrong party, such as an individual when the correct defendant is their LLC, can be enough on its own to get the case dismissed.
Court forms come from the Arizona Judicial Branch website. Superior Court filers use the Civil Complaint form (CVC10F) and Summons (CV11F); Justice Court filers use separate complaint (AOCLJCV2F) and summons (AOCLJCV3F) forms.9Arizona Judicial Branch. Civil Forms Some local courts prefer their own versions, so check with the specific courthouse.
What the Complaint Must Say
The complaint tells the court and the defendant what the case is about. Arizona’s rules require a short, plain explanation of why the court has authority to hear the case, what happened, and what relief you want, whether that is a dollar amount, return of property, or something else.10New York Codes, Rules and Regulations. Arizona Rules of Civil Procedure Rule 8 – General Rules of Pleading Every complaint carries a caption at the top listing the court’s name and all parties.11New York Codes, Rules and Regulations. Arizona Rules of Civil Procedure Rule 10 – Form of Pleadings You do not need to cite statutes, but you do need enough detail that the other side understands the accusation and the court can see a plausible legal claim.
The Summons
The summons is the formal notice telling the defendant a lawsuit has been filed and that they must respond within a set number of days or face a default judgment. You prepare it alongside the complaint, but it only becomes effective once the Clerk signs and seals it. Each defendant needs a separate summons.
File with the Clerk and Pay the Fee
Submitting the completed complaint and summons to the Clerk of the Court is what officially starts the lawsuit. You can file in person at the courthouse or, for certain case types and counties, use the AZTurboCourt electronic system online.12Arizona Judicial Branch. AZTurboCourt Availability varies: in some Justice Courts the online system only generates forms you then print and deliver in person.
Fees depend on the court and county. The statewide base fee for a civil complaint in Superior Court is $252, though county surcharges can push the total to $367 or more.13Arizona Judicial Branch. Superior Court Filing Fees In Justice Court the base civil filing fee is $86, and a small claims filing costs $30.14Arizona Judicial Branch. Justice Court Filing Fees Confirm the exact figure with your courthouse before you go.
If you cannot afford the fee, you can apply for a deferral or a waiver. A deferral postpones payment or sets up a payment plan; a waiver eliminates the fee entirely for people who cannot pay. You submit a written application with proof of your financial situation and the court decides.15Arizona Judicial Branch. Administrative Directive No. 2022-06 – Application for Deferral or Waiver of Court Fees and Costs
Once the Clerk accepts your papers and payment, you get a case number back and a signed, sealed summons. That sealed summons is what authorizes you to formally notify the defendant, and you have 90 days from filing to do it.16New York Codes, Rules and Regulations. Arizona Rules of Civil Procedure Rule 4 – Summons
Serve the Defendant
Service of process is the formal delivery of the complaint and summons to the defendant. Arizona’s rules are strict about how this happens, and getting it wrong can invalidate everything after.16New York Codes, Rules and Regulations. Arizona Rules of Civil Procedure Rule 4 – Summons
Personal Service
The most common method is personal service by a licensed private process server or a sheriff’s deputy who physically hands the papers to the defendant. You cannot serve the papers yourself. The server can also leave the documents with another person of suitable age at the defendant’s home or usual place of business. Private process server fees typically run $40 to $100 per attempt, with surcharges possible for rush delivery, multiple attempts, or long-distance travel.
Waiver of Service
You can ask the defendant to accept the documents voluntarily and skip the formal delivery. If they sign a waiver, you avoid the process server’s fee. In exchange, the defendant gets more time to respond: 35 days from the date you sent the waiver request, rather than the standard 20 days that would apply after personal service within Arizona.
Service by Publication
When a defendant cannot be found despite genuine effort, you can ask the court to authorize service by publication in a newspaper in the county where the case is filed.17New York Codes, Rules and Regulations. Arizona Rules of Civil Procedure Rule 4.1 – Service of Process Within Arizona This requires a court order and is only available after you show you tried to find and serve the defendant personally. If no newspaper is published in the relevant county, publication in an adjoining county’s newspaper is allowed.
The 90-Day Deadline and Proof of Service
Service must be completed within 90 days of filing the complaint. Miss it without showing good cause and the court will dismiss the case without prejudice, meaning you can refile but you lose the fee and time already spent.16New York Codes, Rules and Regulations. Arizona Rules of Civil Procedure Rule 4 – Summons A valid reason for delay can get you an extension.
After the defendant is served, the person who delivered the papers has to file a proof of service, sometimes called an affidavit of service, with the court. The sworn document records the date, time, location, and method of delivery. Without it, the court has no evidence the defendant was properly notified and the case cannot move forward.
What Happens After Service
A defendant served inside Arizona has 20 days to file a written response. A defendant served outside Arizona gets 30. If no response arrives, you can apply for a default, which becomes effective 10 days after the application is filed, giving the defendant a final window to respond before a default judgment is entered.18New York Codes, Rules and Regulations. Arizona Rules of Civil Procedure Rule 55 – Default; Default Judgment The application must include a copy of the proof of service and the defendant’s last-known mailing address.
If the defendant does respond, both sides enter the exchange-of-information phase. Arizona requires each party to provide a verified disclosure statement within 30 days of the first responsive pleading, covering witnesses, documents, damages calculations, and other categories. Both sides can then use formal discovery tools, including written questions answered under oath, requests for documents, and depositions, to gather additional evidence. Discovery is often the longest and most expensive part of a civil case.
If your Superior Court case involves $65,000 or less, expect a referral to compulsory arbitration.6Arizona Legislature. Arizona Revised Statutes 12-133 – Arbitration of Claims; Agreement of Reference An arbitrator hears abbreviated presentations and issues a decision. Either side can reject that award and demand a trial, but if the trial result is not more favorable than the arbitration award, the rejecting party can be ordered to pay the other side’s costs. Many cases settle during or soon after the arbitration stage.
