What Not to Do While a Private Investigator Works Your Case

01Why it matters

Why your behavior during the case matters so much

Most investigations, especially surveillance, depend on the subject acting normally. If they sense they are being watched, they may change their schedule, cancel plans or become careful about where they go and who they meet. The investigator then ends up spending paid hours documenting a routine that no longer reflects reality.

Your conduct can also affect how evidence is viewed later. If you gathered information illegally, argued with the subject on camera or posted accusations online, the other side's attorney may use that against you. The goal is simple and worth repeating: let the investigation run quietly and keep your own record clean.

02Mistake one

Do not confront the subject or drop hints

The urge to confront someone is strongest right after you hire an investigator, because the suspicion finally feels real. A confrontation almost always makes the investigation harder. Even a pointed question, such as asking where someone was on a specific night, can signal that you know more than you should.

Changes in your own behavior can be just as revealing. Suddenly checking their location, going quiet, or showing up unexpectedly where they are can tip them off. As far as possible, keep your routine and tone the same as before you called the investigator. If you feel you cannot, tell your investigator so the plan can account for it.

• Asking leading questions about specific dates or places
• Showing up unannounced where the subject is expected
• Making sudden changes to shared accounts or schedules
• Mentioning details only an investigation would reveal

03Mistake two

Do not tell friends, family or social media

Word travels, often faster than you expect. A sister, coworker or close friend may mean well, but they may also know the subject, or know someone who does. Once more people know about the investigation, the chance of it reaching the subject goes up quickly, and you lose control of what is said.

Posting online is even riskier, even in private groups. Vague posts about betrayal, screenshots, or comments about an ongoing case can be seen by the subject and can surface later in litigation. Keep discussion limited to your investigator and your attorney, and use a private email account and phone the subject cannot access.

04Mistake three

Do not gather evidence yourself in ways the law forbids

Some of the most serious mistakes involve trying to help. Tennessee law makes it a crime to track someone's vehicle with an electronic tracking device without the owner's consent, and that rule applies to clients as much as investigators. Installing spyware, logging into someone else's email or social media, or reading their phone without permission can create civil and criminal exposure.

Tennessee is a one-party-consent state for recording conversations, which means you can generally record a conversation you are part of. That does not allow you to hide a recorder to capture conversations between other people. Federal law also prohibits obtaining phone records by pretexting. If you are unsure whether something is legal, ask your attorney before you do it.

05Mistake four

Do not contact witnesses or play investigator

It is natural to want to talk to the neighbor who saw something or the coworker who might know more. But if you contact a potential witness first, you may shape their memory, alert them to the case, or give the other side a reason to question the witness's independence. A professional interview by an investigator is documented and neutral in a way a personal conversation is not.

The same goes for following the subject yourself, driving past a location, or sitting in a parking lot. You risk being seen, you risk a confrontation, and you may create a record that looks like harassment. Leave field work to a licensed investigator who knows how to do it lawfully and discreetly.

06What to do instead

What to do instead while you wait

Being useful to your own case mostly means being a good source of information. Write down new observations as they happen: dates, times, what you saw or heard, and any change in schedule. Send them to your investigator promptly. A late meeting mentioned at dinner can be exactly the lead that makes the next surveillance session productive.
