Forget the trench coat. Modern investigative work is mostly patient observation, careful documentation, and turning scattered facts into evidence that holds up. If you're thinking about this career, here's the real job — case type by case type, including exactly what you'd be expected to deliver.
The honest version: most PI work isn't dramatic. It's sitting in a car for six hours, writing meticulous reports, searching public records, and knowing precisely where the legal lines are. The investigators who succeed are organized and disciplined — not the lone-wolf types from the movies.
One of the steadiest sources of investigative work, and the one most people misunderstand. Insurers and the third-party administrators who manage their claims (firms like Sedgwick or Gallagher Bassett) hire investigators to verify whether a claim — usually workers' compensation — matches the reported injury.
Here's the key thing to understand about this work: the client isn't buying "surveillance" — they're buying a defensible answer. Is this claim legitimate, or are the claimant's activities inconsistent with the injury they've reported? Your job is to document the truth either way, in a form the insurer and its lawyers can actually use.
The bar often isn't catching outright fraud. It's resolving doubt. If a claimant says a back injury prevents lifting more than ten pounds, and you document them loading heavy bags into a car over several days, that contradiction is what the insurer paid for. Equally, if their activity is fully consistent with their restrictions, your report can confirm the claim is genuine.
Illegally obtained evidence is worthless to an insurer — it can't be used and creates liability. Staying inside the law isn't just ethics here; it's the whole value of the work.
Attorneys are one of the most reliable repeat clients an investigator can have. The work is unglamorous but essential to building a case.
Beyond insurance and legal, most investigators handle a mix of these. Each is a different skill, but they share the same DNA: gather facts legally, document them carefully, deliver something the client can act on.
The most universal service — verifying who someone really is. Employers, landlords, and individuals all need it.
Finding someone who's moved, vanished, or doesn't want to be found — for debt, legal, family, or reconnection reasons.
Formally delivering legal documents so a case can proceed — often to people actively dodging service.
Vetting a business, partner, or investment before someone commits money — corporate and individual clients alike.
The fastest-growing part of the field. Increasingly, investigations happen at a keyboard as much as in a car — and clients expect digital fluency.
This spans OSINT (open-source intelligence — mining public social media, records, and online traces), digital forensics (recovering data from devices a client owns), and cyber-fraud and breach work (tracing business email compromise, monitoring for a client's leaked data). Notably, the defensible version of this work is built on public sources or devices and accounts the client owns — not surveilling individuals or accessing someone else's accounts.
If you take one thing from this page, make it this: the job rewards patience and precision far more than nerve.
Surveillance is long stretches of nothing punctuated by a few important minutes. Comfort with boredom is an underrated skill.
Your report is the product. Clear, accurate, defensible documentation is what clients pay for — and what holds up later.
Knowing exactly what you can and can't do — recording laws, privacy, trespass — isn't a constraint on the job. It is the job.
If this sounds like work you'd want to do, start with the licensing requirements for your state — then, when you're established, put your credentials to work.
