Find a Licensed Private Investigator in Arizona

01Why Arizonans hire investigators

When an Arizona matter calls for a licensed investigator

Arizona investigation requests tend to follow the state's growth. A parent in a Maricopa County parenting-time dispute wants a clear record of who is in the other household. A Scottsdale business owner suspects a bookkeeper of skimming. A family in Tucson has lost contact with a relative who moved to a rural part of Mohave County. A claims adjuster doubts that a Pinal County warehouse worker is as limited as the medical file says. In each case someone needs facts gathered lawfully and reported in a form that an attorney, judge or insurer can rely on.

Arizona treats that kind of fact-gathering for pay as licensed work. Under A.R.S. 32-2401, a private investigator is anyone who, for consideration, engages in business to furnish, agree to make or make investigations into matters such as a person's identity, conduct, movements or whereabouts, the credibility of witnesses, missing persons, or the cause of a loss or injury, or to secure evidence for trial. So the useful first question is not which website looks polished. It is whether the person you hire actually holds Arizona authority to do the work and has handled matters like yours in that county.

• Family law: legal decision-making, parenting time and divorce in Superior Court
• Civil litigation: witness locates, interviews and asset research
• Insurance and workers' compensation claim reviews
• Business matters: employee theft, fraud and due diligence
• Personal safety: documenting harassment for counsel or police

02Licensing

How licensing works for a private investigator in Arizona

Arizona regulates private investigators under Title 32, Chapter 24 of the Arizona Revised Statutes, and the program is run by the Licensing Unit of the Arizona Department of Public Safety. The structure is built around the agency. An agency license is issued to a qualifying party who meets the experience and background requirements, and for a corporation or LLC that qualifying party is the individual responsible for managing the agency. Partners and corporate officers enroll as associates. Investigators who work for the agency are registered as employees, and the statute defines a registrant as an employee of a licensed agency who is qualified to perform its services.

The core prohibition is A.R.S. 32-2411. It says a person may not act or attempt to act as a private investigator, or represent that they are one, unless registered under the chapter and working within the scope of employment for a licensed agency. A knowing violation is a class 1 misdemeanor. Section 32-2454 adds an advertising rule: display and broadcast advertising that solicits business must carry the licensee's name and license number as they appear in DPS records, and advertising may not be false, deceptive or misleading.

Legislation passed in 2025 adjusted agency renewals, set a surety bond requirement and lengthened the agency license term, but the basic rule did not change. For a client, the practical point is simple. Ask for the agency name and license number, check them with DPS, and keep a record of the check with your file. Some Arizona cities have also had their own business rules for private investigation services, so an investigator who works locally should know whether a city license applies.

03Legal limits

What licensed Arizona investigators can and cannot do

An Arizona license is permission to investigate for pay, not police power. A licensed investigator cannot arrest anyone, search property, compel a person to answer questions or enter private land without permission. The work is built on public places, public and court records, lawful data sources and voluntary interviews. Recording falls under A.R.S. 13-3005, which makes unlawful interception a crime, and A.R.S. 13-3012(9), which exempts interception made with the consent of a party to the communication or a person present during it. Arizona is therefore generally described as a one-party consent state, although calls with people in all-party states raise separate questions.

Electronic tracking deserves extra care. Arizona's stalking statute, A.R.S. 13-2923, defines a course of conduct to include using any electronic, digital or global positioning system device to surveil a specific person without authorization, either continuously for twelve hours or more or on two or more occasions. The statute excludes activity authorized by law, but it does not spell out a general exemption for investigators. Anyone thinking about a tracker on a car, especially one they do not own outright, should speak with an attorney first.

Pretexting has its own limits. Federal law restricts obtaining financial records and telephone records through false pretenses, and the federal Driver's Privacy Protection Act limits use of motor vehicle records to permitted purposes. Impersonating a peace officer is a crime in Arizona. A careful investigator will explain which methods fit the facts and which do not, and your attorney can confirm how these rules apply to the facts of a specific case.

• Generally lawful: observation from public places and public records research
• Generally lawful: recording a conversation the investigator takes part in
• Restricted: GPS monitoring of a person without authorization
• Not allowed: posing as police or using false pretenses for bank or phone records

04Regions

Why local knowledge matters across Arizona

Most Arizonans live in the Phoenix and Tucson metros, but the state is large and the distances are real. Flagstaff sits roughly two and a half hours north of Phoenix by interstate, and the drive from Phoenix to Yuma or to Lake Havasu City takes about as long. Maricopa County alone holds a majority of the state's people, with Superior Court operations in downtown Phoenix and regional court centers elsewhere in the Valley. Fast-growing places such as Buckeye, Queen Creek, San Tan Valley and the city of Maricopa in Pinal County change so quickly that new subdivisions often outrun mapping and data sources.

The border counties work differently. Yuma, Santa Cruz, Pima and Cochise counties all touch Mexico, and ports of entry such as Nogales and San Luis shape traffic, commerce and family ties. Northern and eastern Arizona are rural, with long stretches between towns, seasonal tourism around the Grand Canyon and the White Mountains, and summer heat in the low deserts that affects how long surveillance can be sustained from a vehicle.

Arizona is also home to 22 federally recognized tribes, and reservation land covers roughly a quarter of the state, including much of the Navajo Nation in Apache, Navajo and Coconino counties and the Tohono O'odham Nation west of Tucson. Civil and criminal jurisdiction on tribal land can differ from the surrounding county and depends on the people and facts involved. An investigator working near tribal land should raise it early, and the client's attorney should weigh in before any field work there.

05Pricing

How Arizona investigators usually price their work

Every investigator sets and quotes their own fees, and the structure tends to follow the type of work. Surveillance and field work are usually billed by the hour, often with a daily minimum so a short assignment still covers travel and preparation. Mileage or travel time is commonly added when the work is outside the investigator's home area, which matters in Arizona when a Phoenix-based case leads to Kingman, Show Low or Sierra Vista. Database searches, court record copies and similar costs are often passed through as expenses.

Many investigators ask for a retainer before work begins and bill against it, then refund or invoice the balance when the matter closes. Some quote a set price for a narrow task such as a single records search. Before you agree, ask what is included, how often you will receive updates, whether report writing and video preparation are billed separately, and what happens if the subject stays home on a planned surveillance day. A clear written agreement protects both sides and makes the final invoice easier to read.

06Before the first call

How to prepare for the first call with an Arizona investigator

The first conversation goes best when you can state the goal in a sentence or two and explain what you will do with the answer. If a case is open, have the Superior Court case number, the county, your attorney's contact details and any hearing dates ready. For a person, gather full name, date of birth if known, recent addresses, vehicles, employer, a current photo and what you know of the person's routine. For a business concern, pull together the documents that raised the question and the names of the people involved.

Expect the investigator to ask questions that test whether the goal is lawful and realistic. A licensed investigator will turn down work that looks like an attempt to harass someone or to find a person who has good reason not to be found, and may ask to see court orders in protective order or custody matters. Mention anything that affects safety, such as weapons, prior violence or an order of protection. The more accurate the picture, the more useful the quote. When you are ready, send a short request with the county and the goal.

• Your goal in one or two sentences
• County and city where the activity happens
• Names, dates of birth, addresses and vehicles you already know
• Case number, court and attorney contact, if any
• Budget range and any firm deadline

Cities

Top 20 cities in Arizona for private investigator requests

These are Arizona's 20 largest incorporated cities and towns by the Census Bureau's July 2025 population estimates, with the county that holds most of each one. Several Valley cities cross county lines, and unincorporated communities such as San Tan Valley do not appear here, so include the street address or ZIP code in your request so it reaches an investigator who knows that area.

Counties

All 15 Arizona counties for investigator requests

Arizona has only 15 counties, so all of them appear below, ranked by the Census Bureau's July 2025 estimates. Each county has a Superior Court with general trial jurisdiction, along with justice courts and city courts. Many counties are very large, so an investigator who regularly works one part of a county may still need to travel for another.

Licensing

How Arizona licenses private investigators

Arizona licenses the agency and registers the people who work for it. A private investigator agency license is issued through a qualifying party who meets the experience requirements, partners and officers enroll as associates, and each investigator employee must be registered with the Department of Public Safety. A.R.S. 32-2411 bars anyone from acting as, or representing themselves as, a private investigator without that status. Advertising must also show the licensee's name and license number.
