Southwest Florida produces a distinctive kind of case: a seasonal marriage that looks different in Naples than it does in New Jersey, a widowed parent in Sarasota with a new “companion” and a changing will, a Cape Coral contractor who took the deposit and disappeared, a boat that was supposed to be worth what the seller said, a partner in a Fort Myers medical practice whose accounts do not reconcile. FSO Guard’s licensed private investigators in Naples, Fort Myers and Sarasota (Florida Class A agency A 1000095) handle these matters discreetly and legally, with a report that stands up in the Twelfth and Twentieth Judicial Circuits.
Private investigation services on the Gulf coast
Surveillance and infidelity investigations
Covert surveillance with time-stamped video, vehicle and foot surveillance, activity documentation for divorce, alimony and cohabitation matters — including the gated communities, country clubs and marinas where discretion is everything. Learn how infidelity investigations work.
Asset searches and hidden-asset investigations
Asset searches for divorce, judgment enforcement and estate disputes: real property across counties, boats and aircraft, business interests, bank and brokerage leads through lawful methods, and a clear picture of what is really owned in a region where wealth is often held quietly.
Elder exploitation and estate matters
Documentation of caregiver or companion conduct, background checks on new people in an elderly relative’s life, review of property transfers and powers of attorney, and reports for elder-law attorneys, guardianship proceedings and Adult Protective Services.
Background checks and due diligence
Background checks on contractors, caregivers, tenants, business partners, fiancés and household staff; due diligence for medical practices, real-estate and marine transactions common on the Gulf coast.
Contractor and real-estate fraud
Post-hurricane rebuilding brought a wave of deposit fraud and unlicensed contracting to Lee and Collier counties. We locate the contractor, document the scheme, identify other victims and assets and produce a package for your attorney, the State Attorney or the DBPR. See fraud investigations.
Skip tracing, process service and litigation support
Locating people — debtors, witnesses, heirs, seasonal residents who left for the summer — process service throughout Southwest Florida and litigation support for family, probate, personal injury and commercial attorneys.

Why Gulf coast clients hire FSO Guard
- Licensed agency, licensed investigators. Class A agency license A 1000095, Class C investigators, insured, with a named investigator behind every report who will testify if needed.
- Built for discreet communities. Pelican Bay, Port Royal, Grey Oaks, Bonita Bay, Gulf Harbour, Lakewood Ranch, Longboat Key and Siesta Key are small worlds where a stranger is noticed. Our investigators plan surveillance so nobody but you knows it happened.
- Seasonal-resident experience. Many of our Southwest Florida clients live in the Northeast or Midwest half the year. We work by secure video call and encrypted file delivery, coordinate with attorneys in two states and time surveillance around the season.
- Evidence that survives court. Continuous video, unbroken chain of custody, dated and signed reports and strict compliance with Florida’s surveillance and recording laws.
- Straight talk. If a case cannot be legally or practically proven, we say so at the consultation, not after the retainer is spent. Our guide on how to hire a private investigator lists the questions worth asking any agency.
- One agency across Florida. When a subject moves to Tampa, Orlando or Miami, or a witness lives across the state, the same team and the same case file follow it — see our private investigator in Florida page.
How a case works
- Confidential consultation. A free call about your situation, what you need to prove and the legal context. We tell you what is realistic.
- Written plan and retainer. Methods, hours and a written estimate. Work begins when the retainer is received, often within 24–72 hours.
- Investigation and updates. Surveillance, records work and interviews with regular updates so you and your attorney can make decisions while the case is live.
- Court-ready report. A dated, signed report with video, photographs and documents, delivered securely, with the investigator available to testify.
