Who we are

Trusted Private Investigator Jacksonville

Mayn Investigations provides professional private investigator services across Jacksonville and the greater Northeast Florida region. Our licensed investigators support individuals, attorneys, and businesses throughout Duval and St. Johns Counties, from downtown Jacksonville to the beaches, St. Augustine, Ponte Vedra, and Nocatee. Every investigator on our team comes from a military or law enforcement background, and our agency is licensed and insured in the state of Florida under License #A3400126. Whether you need surveillance, background research, or litigation support in Jacksonville, we handle each case with discretion and a clear understanding of Florida law.

Investigative Support for Jacksonville Attorneys

Jacksonville is in Duval County, which shares Florida’s Fourth Judicial Circuit with Clay and Nassau Counties. Duval circuit and county cases are heard at the Duval County Courthouse on West Adams Street downtown. Under the 2023 appellate realignment, Fourth Circuit appeals now go to the Fifth District Court of Appeal, and federal cases are filed in the Middle District of Florida’s Jacksonville Division. Nearby St. Johns County, including St. Augustine and Ponte Vedra, is in the Seventh Judicial Circuit.

Jacksonville’s logistics, banking, healthcare, and port-related businesses generate business litigation, trade secret and non-solicitation disputes, compliance and fraud inquiries, and IP issues involving counterfeit products. We help Northeast Florida counsel by finding and interviewing witnesses, researching corporate and asset records, reviewing open-source and social media evidence, and conducting surveillance in family law matters, with each step documented for discovery and hearings.

Our Florida license lets us work statewide, so a Jacksonville matter with parties in Central Florida, Tampa Bay, or South Florida can stay with one investigative team.

Private Investigator Jacksonville: Case Types and Courts

Duval, Clay and Nassau Counties make up the Fourth Judicial Circuit, and St. Johns County sits in the Seventh. Jacksonville counsel often need work that crosses those lines, and we plan field work and records research accordingly.

Logistics, port and banking disputes

JAXPORT, distribution, transportation, banking and insurance-adjacent businesses generate contract, vendor and employee disputes. We research companies and ownership, interview witnesses, and document observable activity for counsel.

Military-community and relocation matters

With Naval Air Station Jacksonville and Naval Station Mayport nearby, witnesses and parties sometimes relocate on short notice. We locate them through lawful records research and coordinate statements with counsel.

Family law and asset research

Cohabitation, residence and income questions in Duval family cases, and asset research before filing or after judgment.
