What Private Investigators Can and Can’t Do

Private investigators (PIs) are professionals trained to gather information and conduct investigations while adhering to strict legal guidelines. They often assist in uncovering infidelity, verifying backgrounds, locating missing persons, and gathering evidence for court cases. But what are the legal limits of their work?

Let’s break down what private investigators can and cannot do to ensure your case stays ethical and lawful.

What Private Investigators Can Do Legally

• Conduct Surveillance: PIs can legally observe and document activity in public spaces where there is no expectation of privacy.
• Access Public Records: They can search court records, property records, and other publicly available databases to gather information.
• Interview Witnesses: PIs can legally approach and interview individuals related to a case, provided it’s done without harassment or coercion.
• Use GPS Tracking (With Permission): A PI can use GPS tracking devices, but only on vehicles or property they own or have written permission to track.
• Document Facts for Counsel: PIs can preserve observations, records and statements using lawful methods. A court decides admissibility.

What Private Investigators Cannot Do

• Wiretap Conversations: Recording or intercepting private conversations without consent is illegal in most jurisdictions.
• Trespass on Private Property: PIs cannot enter someone’s home, business, or private property without permission.
• Hack Phones or Computers: Accessing digital devices or accounts without consent violates privacy laws.
• Impersonate Law Enforcement: PIs are not police officers and cannot misrepresent themselves as such.
• Harass or Intimidate: All interactions must remain ethical and respectful, without coercion or intimidation.

The Florida specifics worth knowing

Licensing. Private investigation in Florida is regulated under Chapter 493, administered by the Florida Department of Agriculture and Consumer Services. Agencies hold an "A" licence; individual investigators hold a "C" licence. Both are publicly searchable, and asking for the number is reasonable.

Recording. Florida is an all-party consent state for the interception of oral communications under F.S. 934.03. Recording a conversation you are not a party to, without consent, is a felony — not a technicality. This is the single most common thing clients ask for and the most common thing a licensed investigator will decline.

Tracking devices. Florida restricts placing a tracking device or application on another person's vehicle or property without consent. Ownership of the vehicle is not automatically sufficient authority, particularly between spouses during a dissolution. Ask before, not after.

Consumer reporting. Where a report is used for employment, tenancy, credit or insurance decisions, the federal Fair Credit Reporting Act imposes obligations on how information is gathered, disclosed and acted on. An investigative report prepared outside that framework should not be repurposed into a hiring decision.

Pretexting. Obtaining financial records or telephone records by impersonation is separately unlawful under federal law. "We know someone who can pull the phone records" is a warning sign, not a capability.

Admissibility is decided by the court

It is worth correcting a common claim: no investigator can guarantee that evidence will be admitted. Lawful collection makes admission possible and keeps the client out of trouble; relevance, authentication, hearsay and privilege are then argued, and a judge rules. Anyone promising "court-admissible evidence" as a product is selling something they do not control.

How to tell whether you are being told the truth

Questions worth asking any investigator before you engage them:

• What is your Florida licence number, and is it an agency or individual licence?
• What exactly will you do, and what will you not do?
• How will findings be documented, and will the report distinguish observation from inference?
• What happens if the evidence does not support what I believe?
• Do you carry liability insurance?

An investigator who answers the fourth question badly is the one most likely to produce evidence that collapses. The correct answer is that you will be told what the record shows, including when it is unhelpful or inconclusive.

Ask About a Lawful Scope

If you are unsure whether what you want is something an investigator can lawfully do, ask before committing to it. Serving Florida and St. Lucie County, we will tell you plainly what is within scope, what is not, and where a question belongs with an attorney instead.
