Stuart's position at the confluence of the St. Lucie River and the Intracoastal Waterway creates a specific investigative profile, vessel fraud, waterfront property disputes, and maritime-adjacent insurance cases.

In the state of Florida, there is no legal distinction between the two terms; both refer to professionals licensed under Chapter 493 to conduct investigative services. While “private detective” is a more traditional term often used in popular culture, “private investigator” is the official designation used by the Florida Department of Agriculture and Consumer Services (FDACS). At McKinnon Investigative Group Inc., we fulfill all state requirements to carry this professional title.
