Find a Licensed Private Investigator in Ohio

01Why Ohioans hire investigators

When an Ohio matter needs a licensed investigator

Most Ohio requests begin with a question that cannot be answered from a phone or a laptop. A Delaware County parent wants proof of what happens during the other parent's parenting time. A Summit County distributor suspects a warehouse lead is moving product out the back. A family in Lima needs to find a relative named in a probate case. A claims adjuster in Hamilton County doubts that an injured worker is as restricted as the file says. Each needs facts gathered lawfully and written up so an attorney, magistrate or insurer can rely on them.

Ohio treats that fact-gathering as a licensed business under Chapter 4749 of the Revised Code. Section 4749.13 says no person shall engage in the business of private investigation unless licensed, and no unlicensed person may advertise or hold themselves out as a licensee. So the first decision is not which ad looks most convincing. It is which investigator actually holds a current Ohio license or registration and has handled your kind of matter in the part of the state where it is happening.

• Family law: custody, parenting time and divorce matters in domestic relations court
• Civil litigation: witness locates, statements and asset research
• Insurance and workers' compensation claim reviews
• Business concerns: employee theft, fraud and due diligence
• Personal safety: documenting harassment or stalking for counsel or police

02Licensing

How licensing works for a private investigator in Ohio

Ohio licenses investigators through the Department of Public Safety, whose Private Investigator Security Guard Services unit, known as PISGS, administers Chapter 4749 for the Director of Public Safety. Under Section 4749.03, a Class A license covers both private investigation and security guard services, a Class B license covers private investigation, and a Class C license covers security guard services only. Licenses can be issued to individuals or to corporations through a qualifying person, and investigators who work for a licensee are registered as employees of that licensee.

Section 4749.13 sets two separate rules. Division (A) bars anyone from engaging in the business of private investigation without a license, and each day of a continuing violation is a separate offense. Division (D) bars anyone who is not a Class A, B or C licensee from advertising that they are one or otherwise holding themselves out as one. That is why Delator Group does not offer or advertise investigations in Ohio and only refers requests to independently licensed investigators.

For a client, the check takes a few minutes. Search the licensee and, if you know it, the employee's name in the PISGS provider search on the department's website, confirm the license class and status, and compare the license number with the contract and website. The Ohio Department of Public Safety publishes PISGS contact information for license questions and complaints.

03Legal limits

What licensed Ohio investigators can and cannot do

A license allows investigative work for pay. It does not grant police powers. A licensed Ohio investigator cannot arrest, search, compel anyone to answer questions or enter private property without permission. Most work happens from public places, through clerk of courts and other public records, licensed databases and voluntary interviews. Recording is governed by Ohio's interception law, R.C. 2933.52, which generally allows a person who is a party to a communication, or who has one party's prior consent, to record it, unless the purpose is to commit a crime or a tort.

Tracking became a specific crime more recently. R.C. 2903.216, which took effect in March 2025, makes it an offense to knowingly install a tracking device or application on another person's property without consent, or to keep it in place after consent is withdrawn. Consent is treated as revoked when a divorce or dissolution is filed or a protection order is issued. The statute contains a narrow exception for licensed private investigators acting for listed purposes, which does not apply when the client is subject to a protection order.

Menacing by stalking under R.C. 2903.211 covers a pattern of conduct that causes someone to believe they will be harmed or causes mental distress. Professional surveillance is therefore planned around a lawful purpose, limited in time and carefully documented. Federal law separately restricts pretexting for phone and bank records and limits access to driver records.

• Generally lawful: observation from public places, public records, voluntary interviews
• Generally lawful: recording a conversation the investigator is part of
• Restricted: tracking devices or apps on another person's property without consent
• Not allowed: posing as police or using pretexts to obtain bank or phone records

04Regions

Why local knowledge matters across Ohio

Ohio has three large metro areas and several smaller ones, each with its own courthouse habits. Central Ohio around Columbus is the fastest-growing, with suburbs spilling into Delaware, Licking, Fairfield and Union counties. Northeast Ohio links Cleveland, Akron, Canton and the Mahoning Valley, where Youngstown and Warren sit near the Pennsylvania line. Southwest Ohio runs from Dayton through Butler and Warren counties to Cincinnati, whose metro reaches into Kentucky and Indiana, so cases there often cross state lines.

Northwest Ohio centers on Toledo near the Michigan border, surrounded by flat farm country. Southeast Ohio is part of Appalachia, with hills, small county seats and Ohio River towns facing West Virginia, where travel times are longer than the map suggests and an unfamiliar vehicle stands out quickly. Lake Erie's shoreline counties have seasonal traffic around the islands and lake towns.

Each of Ohio's 88 counties has a court of common pleas, often with separate domestic relations, juvenile and probate divisions, alongside municipal and county courts, and appeals go to 12 district courts of appeals. Requests sent through Delator Group are matched by county, and you should mention any part of the matter in a neighboring state.

05Pricing

How Ohio investigators usually price their work

Each investigator sets and quotes their own fees, and the structure usually follows the work. Surveillance and field work are most often billed by the hour, commonly with a daily minimum so a short assignment is worth the travel. Mileage or travel time is typical when the job is outside the investigator's home area, such as a Columbus investigator working a case along the Ohio River. Database searches, clerk of courts copies and filing fees are generally passed through as expenses.

Many Ohio investigators ask for a retainer and bill against it, then refund or invoice the balance. Some quote a set price for a defined task, such as a single records search or a background report. Before you agree, ask what the retainer covers, how often you will receive updates, whether report writing and video editing are billed separately, and what happens if the subject stays home on a planned surveillance day. Get the terms in a written agreement.

06Before the first call

How to prepare for the first conversation with an investigator

A good first call is short and specific. Write down what you want to learn, why it matters and what you will do with the answer. If a case is open, have the case number, the court and county, your attorney's contact information and any hearing dates ready. For a person, gather a full name, date of birth if known, last known addresses, vehicles, employer, a recent photo and the person's usual schedule. For a business matter, collect the documents that raised the concern and the names involved.

Expect the investigator to ask whether the goal is lawful and realistic. A licensed Ohio investigator will decline work that looks like harassment or an attempt to find someone with a legitimate reason to stay hidden, and may ask to see court paperwork in custody or protection order cases. Tell the investigator about anything that affects safety, such as weapons, prior violence or an existing order. When you are ready, send a short request with the county and the goal.

• Your goal in one or two sentences
• County and city or township 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 hard deadline

How matching works

How investigator matching works in Ohio

1. 01

   Send your request

   Use the contact form or call. Describe what you need, the county and city or township, any deadline and how you prefer to be reached. Keep sensitive details short at first.

2. 02

   Request review

   Delator Group reviews the request for completeness and a lawful purpose, and may ask a follow-up question about location, timing or whether a case is open.

3. 03

   Referral to an Ohio investigator

   The request goes to an independent investigator who holds an Ohio license, or works for a licensee, in or near the county involved, so local courts and roads are familiar.

4. 04

   The investigator contacts you

   The investigator reaches out, discusses scope and method, quotes their own fee and, if you go ahead, signs a written agreement with you directly.

5. 05

   You verify and decide

   Before signing, look up the licensee in the PISGS provider search and match the license number to the contract. There is no obligation to hire.

Licensing

How Ohio licenses private investigators

Ohio licenses the business owner or company through the Department of Public Safety and registers the employees who work under that license. A Class A or Class B license authorizes private investigation, while Class C is limited to security guard services. Because Section 4749.13 bars both unlicensed investigative business and unlicensed advertising as a licensee, checking the license class and status in the PISGS provider search is the simplest protection a client has.
