Quick answer
Is a private detective the same as a private investigator in Tennessee?
Yes, in everyday language they are the same profession. Tennessee law licenses the role as a private investigator under Tenn. Code Ann. Title 62, Chapter 26, and investigators must work through a licensed investigation company. A private detective is not a police detective: they have no arrest powers and must not present themselves as law enforcement.
01The terms
Private detective, private eye and private investigator
Private detective is the older, more familiar phrase, and private eye comes from detective fiction and old agency slogans. Private investigator, often shortened to PI, is the modern professional term and the one used in Tennessee’s licensing law. Whatever you type into a search bar, you are looking for the same kind of professional: someone licensed to gather information, conduct surveillance, locate people and develop evidence for private clients and attorneys.
What matters is not the title on a website but the license behind it. In Tennessee, anyone who advertises or performs investigative services for hire must hold the proper license, regardless of whether they call themselves a detective, an investigator or a consultant.
Search habits differ by region as well. Many people in Nashville and Middle Tennessee type private detective when they are worried about a spouse, while attorneys almost always say private investigator or simply PI. Neither choice changes who you should hire; it only changes which websites appear first, so look past the wording to the credentials.
02Licensing
What Tennessee law actually licenses
Tennessee regulates private investigation under Tenn. Code Ann. Title 62, Chapter 26, administered by the Department of Commerce and Insurance. The program licenses individual private investigators and private investigation companies. Individual investigators must meet age, background and training requirements, pass an examination and work through a licensed company.
Company licenses carry extra requirements. The company’s qualifying agent must have verifiable investigative experience, generally 2,000 hours, or qualifying education, and must pass an examination on managing an investigation company. The state also notes that out-of-state firms advertising or providing these services to Tennessee residents may be subject to Tennessee licensing rules.
Related licenses are handled separately. Tennessee’s polygraph examiner program, which shared the commission with private investigators for years, was repealed effective July 1, 2026, so the state no longer licenses polygraph examiners. Security guards and armed security officers are licensed under a different program altogether, and holding one of those licenses does not authorize private investigation work.
- Individual private investigator license
- Private investigation company license
- Background check and training requirements
- State examination and continuing education
03Police vs private
How a private detective differs from a police detective
A police detective is a sworn law enforcement officer who investigates crimes on behalf of the public, can obtain search warrants, access restricted law enforcement databases and make arrests. A private detective works for a client, not the state. Private investigators in Tennessee have no special arrest, search or subpoena powers and cannot access systems such as NCIC.
Tennessee law also prohibits private investigators from implying they are law enforcement. A legitimate private detective will not wear a badge that looks official, claim police authority or suggest that people must answer questions. Anyone who does is a red flag, whatever title they use.
The two roles do sometimes meet. Retired police detectives often become licensed private investigators, bringing interview and evidence skills with them, and criminal defense attorneys regularly hire private investigators to examine the work police detectives did. Once someone leaves a police agency, though, their former badge carries no authority in private work.
04The work
What a licensed private detective can do for you
Within the law, a licensed investigator can do a great deal. Common work includes infidelity and custody surveillance in public places, background and due diligence research, locating people through skip tracing, asset searches, interviewing witnesses, supporting criminal defense attorneys, and documenting insurance or workers’ compensation claims.
The limits are just as important. Private detectives cannot hack accounts, obtain phone records without legal process, place trackers on vehicles they do not own, trespass or record conversations they are not part of. A professional will explain those limits before you hire, and their reports will show exactly how each piece of evidence was gathered.
05Hiring
How to hire a private detective in Tennessee
Start by verifying the license with the State of Tennessee, then ask who will actually do the work and whether the firm subcontracts. Ask for a written scope, timeline and price before anything starts, and ask how evidence will be documented for court. A short consultation should leave you with a clear plan, not a vague promise of results.
Location matters less than coverage and accountability. Someone searching for a private detective in Nashville may need surveillance in Franklin, Murfreesboro or Clarksville the same week. Delator Group’s Nashville private detectives and investigators in Memphis, Knoxville and Chattanooga work under one licensed structure statewide.
06Red flags
Red flags when choosing a private detective
Be cautious of anyone who guarantees a specific result, offers to get bank or phone records with no legal process, suggests hacking or secret recording, or asks for a large retainer with no written scope. Also watch for operators who will not give a license number, avoid putting fees in writing or pressure you to decide immediately.
Those warning signs often appear in complaints about unlicensed operators. If you believe you have already been taken advantage of by someone claiming to be a private investigator, Delator’s guide for clients scammed by a PI walks through what to do next.

FAQ
Frequently asked questions
Is private detective a legal title in Tennessee?
Tennessee’s licensing law regulates private investigators and private investigation companies. In everyday use, private detective describes the same profession. What matters is that the person and company hold valid Tennessee licenses, which you can verify with the state.
Can a private detective arrest someone in Tennessee?
No. Private investigators have no police arrest powers and cannot present themselves as law enforcement. They gather information and evidence lawfully for clients and attorneys, and any criminal matter is handled by police and prosecutors.
How do I find a licensed private detective near me in Tennessee?
Verify the license with the Tennessee Department of Commerce and Insurance, check reviews and professional affiliations, and ask for a written scope and price. Delator Group covers all 95 counties from its Nashville headquarters.
Can a private detective get phone records or bank records?
Not on their own. Phone and bank records are protected, and getting them generally requires legal process through an attorney, such as a subpoena in a lawsuit. A private detective who offers to obtain them directly is a warning sign.
How much does a private detective cost in Tennessee?
Costs depend on the type of work, the hours involved and travel. Surveillance is usually priced by the hour or by session, and research is often priced by project. Ask for a written estimate with a defined scope before any work starts.
