GPS tracking laws in Tennessee
A tracker on the wrong car is a crime in Tennessee, and the data it produces is poison in court. Here is where the line sits and how professionals get the same answer lawfully.
The statute
Tennessee Code Annotated § 39-13-606 makes it an offense to knowingly install, conceal or otherwise place an electronic tracking device in or on a motor vehicle without the consent of all owners or lessees of the vehicle, for the purpose of monitoring or following an occupant. The statute carries exceptions, including for parents or legal guardians tracking a vehicle driven by their minor child, for law enforcement acting under a warrant or other lawful authority, and in certain other circumstances the statute spells out.
The practical rule for individuals: if your name is not on the title or lease and the other owner has not consented, do not put a tracker on it. If you co-own the car with your spouse, take advice before relying on co-ownership; the facts and the divorce posture matter.
Common scenarios
| Situation | Generally lawful? | Why |
|---|---|---|
| Tracker on a car titled solely to you | Yes | You are the owner |
| Tracker on your spouse’s car (titled only to them) | No | No consent from the owner |
| Tracker on a jointly titled car during a divorce | Risky; get advice | Consent and intent issues; courts dislike it |
| Tracker on your minor child’s car | Generally yes | Parent/guardian exception |
| Employer tracker on a company-owned vehicle | Generally yes with policy | Employer owns the vehicle; notice is best practice |
| Tracker on an ex’s car to document cohabitation | No | Unlawful; evidence unusable; exposure to charges |
Why the shortcut backfires
People ask private detectives for trackers because they are cheap and tireless. The problems: the data is obtained unlawfully, so it cannot be used; the discovery of the device turns the subject into a victim and the client into a defendant; and a judge in a custody or divorce case will remember who broke the law. A single unlawful tracker can cost more credibility than any evidence it gathers.
This is one of the questions in our guide to what a private detective can and cannot do, and the answer from a licensed agency is always no.
How professionals get the same answer lawfully
- Mobile surveillance. Licensed private detectives follow the subject on public roads and document where the vehicle goes, when it arrives and who is there. Two-vehicle teams handle aggressive drivers and Nashville traffic.
- Stationary surveillance. Documenting the vehicle at the address in question across the nights that matter, which is how cohabitation is usually proven.
- Pattern analysis. Public observations over several sessions establish routine without any device.
- Records. Vehicle registration, parking and toll records obtained through lawful channels, and discovery through your attorney.

Phones, apps and account tracking
Vehicle trackers are only part of the question. Location sharing through a phone, an AirTag dropped in a bag, or a login to someone else’s cloud account each raises its own legal problem: unauthorized access to another person’s device or account can violate federal and Tennessee computer-crime laws regardless of marriage, and Bluetooth trackers used to follow a person are increasingly treated as stalking tools by courts and by the device makers’ own alerts. The same rule applies to all of it: if the device or account is not yours and the person has not consented, do not.
Trackers in divorce and custody cases
Judges see tracker cases regularly and the pattern is consistent: the party who placed the device loses more than they gain. The data is excluded, the other side gains a sympathetic narrative, the placer’s credibility suffers on every other issue, and in custody matters the court may treat it as evidence of poor judgment or of a willingness to intimidate. If you are tempted because surveillance seems expensive, compare the cost of three targeted surveillance sessions to the cost of handing the other side a stalking allegation.
Employer and fleet tracking done properly
- Track only vehicles the company owns or leases.
- Put the policy in writing: what is tracked, when, why and who sees the data.
- Limit tracking to work time where the policy allows personal use.
- Keep access to the data narrow and the retention period defined.
- If an employee uses a personal vehicle for work, do not track it without clear, written consent and advice from counsel.
Trackers and stalking law
Beyond the vehicle statute, Tennessee’s stalking and harassment laws reach conduct that places a person in fear or causes emotional distress through repeated monitoring. A tracker discovered by an ex or a former partner is frequently the first exhibit in an order-of-protection petition, which then restricts the placer’s contact with the person and sometimes with children. People who place trackers to “protect” themselves in a divorce often end up on the wrong side of the protective order.
If you suspect you are being tracked
Signs include a partner who knows where you have been, a device alert on your phone about an unknown tracker traveling with you, or unexplained objects under a seat or bumper. A licensed private detective can perform a sweep of your vehicle and home for tracking and listening devices, document any device found in place, and preserve it as evidence for law enforcement and your attorney. Do not remove or destroy a device before it is photographed and documented; the evidence of who placed it is often the most valuable part.

What tracker evidence looks like in court, and why it fails
A tracker log is a list of coordinates and times with no witness to what happened at them. Even where lawfully obtained, it proves presence of a vehicle, not conduct, and it invites questions about who was driving. Surveillance footage shows the person, the companion and the behavior, with a licensed witness who can be cross-examined. Lawful surveillance is not only the legal route; it is the stronger evidence.
Why the law treats vehicle tracking so seriously
A tracker turns a car into a reporting device for someone the driver did not choose. Legislatures and courts have come to see that as closer to following a person everywhere than to watching them in public, and the law has moved accordingly: consent of the vehicle’s owners is the line, and exceptions are narrow. Tennessee’s statute reflects that judgment, and courts applying it in family cases tend to view unauthorized tracking as a serious intrusion rather than a technicality.
For clients the practical implication is simple. The temptation to place a tracker usually comes from the sense that surveillance is expensive and the tracker is cheap. In Tennessee the tracker is not cheap; it is a potential criminal charge, a civil claim, an exhibit for the other side and a credibility problem in every hearing that follows. Three targeted surveillance sessions are cheaper than any of that, and the evidence they produce is usable.
A tracker case from the wrong side
A husband placed a tracker on his wife’s car, titled only to her, during their separation. She found it, photographed it in place, reported it, and her attorney used it to obtain an order of protection and to argue his judgment in the custody case. The data from the tracker was never admitted; the fact of the tracker was. The surveillance he could have hired for the cost of two sessions would have documented the same overnights lawfully. He paid far more, in every sense.
If you find a tracker on your own car
- Photograph it in place before touching it.
- Do not destroy it; it is evidence.
- Report it to law enforcement and tell your attorney, especially in a divorce or custody matter or where stalking is a concern.
- A licensed private detective can perform a counter-surveillance sweep of your vehicle and home; see counter-surveillance sweeps.
Questions people ask before they call
Not unless you are an owner or lessee of the vehicle and any other owner consents. Doing so otherwise can be a criminal offense and the data will not help your case.
Only with the lawful consent of the vehicle’s owners. Licensed agencies decline tracker requests on vehicles the client does not own and use lawful surveillance instead.
Tennessee’s statute includes an exception for parents or guardians tracking a vehicle driven by their minor child.
Employers generally may track vehicles they own; clear written policy and notice are best practice.
Different statutes can apply to phones and accounts. Accessing someone else’s phone or account without authorization raises separate legal problems. Take advice.
