What separates Miami private investigators
If you’re an attorney, you need evidence that survives cross-examination and an investigator who answers the phone. If you’re a private client, you need discretion and someone you can reach when the worry hits. Most firms on this list carry a 5.0 Google rating, so the stars won’t decide it. Where the office is, when someone picks up, and what you get at the end will.
Seven of the eight firms have Miami addresses, four of them on Brickell Ave. Wasser Investigations is in Coral Gables and covers Miami as one of the South Florida areas Wasser Investigations serves. Hours range from weekdays only at Crossroads and Specialized to 24 hours every day at Bolton, Miami Investigation Corp, and PI Fast.

Private investigator questions from Miami readers
How do I check if a private investigator is licensed in Florida?
Ask the Miami firm for its Florida agency license number before you share case details, then confirm it with the state licensing office. A real number is specific. Wasser Investigations in Coral Gables, for example, holds Florida Agency License No. A3200002. Get the number in writing, and ask whether the investigator doing your fieldwork holds a license too.
Will a private investigator’s evidence hold up in court in Miami?
It can, but no Miami investigator can promise it, because the court decides. What helps is how the work is gathered and documented. Wasser Investigations delivers findings in a court-ready format with supporting source data, and its licensed notaries execute sworn statements and affidavits. Learn more about surveillance video that holds up in court.
Is there a private investigator in Miami open 24 hours?
Yes. Three Miami firms on this list are open 24 hours a day, every day: Bolton Investigations on SW 53rd St, Miami Investigation Corp on SW 27th St, and PI Fast on Brickell Ave. Grey Ghost on Brickell Ave is open daily from 9 a.m. to midnight.

Can I hire a private investigator in Miami for a cheating spouse or custody case?
Yes. Wasser Investigations, based in Coral Gables and serving Miami, handles surveillance for suspected infidelity, cheating spouse, and child custody matters for private clients. The work stays discreet, and findings come in a court-ready format in case the matter reaches a judge. If you’re unsure what to watch for first, start with these signs of a cheating spouse worth documenting.
Can an out-of-state law firm hire a Miami private investigator?
Yes. Wasser Investigations in Coral Gables works Miami-Dade, Broward, and Palm Beach Counties, offers statewide coverage when a matter needs it, and coordinates nationwide work when the case calls for it. An out-of-area firm gets one licensed Florida agency for the fieldwork, with court-ready reports and sworn statements taken by licensed notaries.
What should I ask about private investigator fees in Miami?
Ask any Miami investigator for the fee terms in writing before work starts. Get the hourly or flat rate, what counts as billable time, how expenses are charged, and whether a retainer applies. The total depends on the case type, how many hours of surveillance it takes, and how fast you need results.
