What a private detective can and cannot do in Tennessee
The rules that separate usable evidence from a lawsuit. What licensed private detectives in Nashville may lawfully do, what they must refuse, and why it matters to your case.
What a licensed private detective can do
- Observe and document a person's conduct in public places, including photo and video surveillance from a lawful vantage point.
- Follow a subject in a vehicle on public roads and document where they go and who they meet.
- Locate people through public records, permissible databases, field work and interviews.
- Search public records: property, court filings, judgments, liens, business registrations, licenses.
- Interview witnesses who agree to speak, and record conversations the private detective is a party to.
- Conduct lawful undercover and pretext work that does not impersonate law enforcement or government, and does not obtain protected records by deception.
- Serve legal process, and testify to what was observed and how it was documented.
What a private detective cannot do, in Tennessee or anywhere
- Obtain phone records, text messages, email content or bank records without legal process.
- Place a GPS tracker on a vehicle the client does not own or control.
- Wiretap, bug a room, or record a conversation they are not part of.
- Trespass on private property, enter a home, or look through windows from inside the property line.
- Impersonate a police officer or government official, or use a badge-style credential to imply authority.
- Access credit reports or protected consumer data without a permissible purpose under the FCRA.
- Hack accounts, install spyware or guess passwords, even on a spouse's device.
- Make an arrest beyond what any citizen may lawfully do, or carry out harassment or intimidation.
Why lawful methods decide whether evidence is usable
Tennessee courts will exclude evidence obtained unlawfully, and opposing counsel will attack it first. Beyond exclusion, an unlawful tracker, recording or records pull can expose the client to civil liability or criminal charges. A licensed Nashville private detective agency builds the case the other way around: lawful vantage points, time-stamped exhibits, chain of custody and a private detective who can explain every step under cross-examination.
That is why Pinnacle refuses the shortcuts. If a prospective client asks for phone records, a tracker on an ex's car or a hidden camera in someone else's home, the answer is no, followed by an explanation of what we can lawfully do instead, which is usually more than people expect.

| No trackers on others’ vehicles | T.C.A. § 39-13-606 | Consent of the vehicle’s owners is required; narrow exceptions |
| No pretexting for phone records | Federal telephone-records privacy law | Carrier records come only through lawful process or the account holder |
| No pretexting for bank records | Gramm-Leach-Bliley Act | Account information comes only through discovery or court process |
| Consumer reports need a permissible purpose | Fair Credit Reporting Act | Credit and certain background reports require consent and proper use |

Gray areas, and how we handle them
- Pretext interviews. Lawful pretexts (a private detective not announcing the purpose of a conversation) are a normal tool; pretexts that obtain protected records, impersonate government or induce a crime are not. We stay on the lawful side and document the approach.
- Jointly owned vehicles and shared accounts. Co-ownership complicates consent; we advise clients to get legal advice rather than rely on it, and we do not place devices on such vehicles.
- Children. A parent’s authority over a minor’s devices and accounts is broader, but recording a child to capture the other parent, or using a child as a surveillance tool, is both unlawful in many forms and damaging in court. We do not involve children.
- Drones. Lawful in many settings, with FAA rules and Tennessee privacy law limiting where and how; we use them only where appropriate.
- Gated communities. Entering under false pretenses is trespass; entrance coverage and lawful access are the alternatives.
Requests we decline, and what we offer instead
| The request | Our answer | What we do instead |
|---|---|---|
| “Get her texts.” | No | Document who she meets and where; help counsel target discovery |
| “Put a tracker on his truck.” | No | Mobile and stationary surveillance from public places |
| “Get into his email.” | No | Public social media; records; discovery through counsel |
| “Find out what’s in her bank account.” | No | Property, vehicle, entity and lien search; lifestyle documentation |
| “Pose as a cop and scare him.” | No | Lawful interviews; documentation for a protective order if warranted |
| “Follow my ex who has a protective order against me.” | No | Nothing; we decline the engagement |
The ‘instead’ column is where cases are actually won.
Why the lawful route is the stronger route
Clients sometimes experience these limits as obstacles. In practice they are the reason the evidence works. A Tennessee judge expects lawful methods and discounts anything else; opposing counsel attacks the method before the substance; and a client who crossed a line hands the other side a narrative that overshadows the facts. Lawful, documented conduct from public places, corroborated by records and presented by a licensed witness, is both admissible and persuasive. The shortcut is neither.
Common situations, and the lawful route
| Situation | Lawful approach | Off limits |
|---|---|---|
| Suspected infidelity | Surveillance in public, cohabitation documentation, social media review | Phone cloning, spyware, trackers on the other person's car |
| Custody concerns | Documenting pick-ups, conduct in public, living conditions visible from public view, witness interviews | Entering the other parent's home, recording the child without consent where restricted |
| Collecting a judgment | Asset searches in public records, employment verification, business entity research | Pulling bank records without a court order |
| Workplace theft | Covert surveillance of company property with employer consent, inventory audits, interviews | Recording in restrooms or private areas, searching personal devices |
| Finding a person | Skip tracing, field verification, respectful first contact | Pretexting a bank or carrier for their records |
Questions people ask before they call
No. Phone and text content and carrier records are protected by federal and state law and are only obtainable through legal process such as a subpoena in a pending case. Anyone offering to pull them for you is proposing a crime.
Not on a vehicle you do not own or have the owner's consent to track. Tennessee law restricts electronic tracking of another person's vehicle, and evidence from an unlawful tracker can sink a case and expose the client.
Tennessee is a one-party consent state, so a private detective may record a conversation they are part of. Recording a conversation between other people, or planting a device, is unlawful.
No. Surveillance is conducted from public places or with the permission of the property owner. Peering into a home, climbing a fence or entering a gated community without lawful access is off limits.
A licensed private detective can search public records and permissible databases. Credit reports and certain employment screening fall under the Fair Credit Reporting Act and require a permissible purpose and, often, the subject's consent.
Lawfully gathered, time-stamped, properly preserved evidence from a licensed private detective is routinely accepted in Tennessee chancery, circuit and criminal courts. The methods matter as much as the findings.
