Signs Your Partner May Be Cheating: What Private Investigators Look For
Infidelity cases are one of the most common reasons people hire private investigators in Florida. Whether you live in Tampa,...
If you’re considering hiring a private investigator or if you suspect someone has hired one to look into your life you’re probably wondering:
“What information can a private investigator obtain?”
The idea of someone digging into your background may feel uncomfortable, but there are clear legal limits to what licensed PIs can access. And just as importantly, there are powerful tools they can legally use to uncover the truth.
This guide breaks down what PIs can (and can’t) find out legally and ethically, so you know where the boundaries are.
Licensed private investigators have access to a variety of data sources that the average person doesn’t. However, they still must comply with federal and state privacy laws. Here’s what’s legally accessible:
These are often the most powerful tools in a PI’s arsenal.
Most of this data is technically public, but it takes training and tools to efficiently search and cross-reference across counties, states, and agencies.
PIs can use commercial databases, skip-tracing tools, and public records to trace:
This information is commonly used in child custody, infidelity, and fraud investigations.
PIs conduct deep digital dives to uncover:
Known as Open Source Intelligence (OSINT), this method is especially effective in infidelity, custody, or employee monitoring cases.
PIs are trained to gather information from:
While they can’t impersonate law enforcement, they can conduct interviews under pretext (within legal limits) to learn useful insights.
Surveillance is a cornerstone of private investigation, when done legally.
Surveillance must be discreet, non-threatening, and must not involve trespassing or illegal tracking devices.
Despite their tools and training, PIs are not above the law. Here’s what they’re legally forbidden from accessing without consent or a court order:
Restricted Information | Why It’s Protected |
Phone call logs, text message content | Protected under ECPA and carrier privacy laws |
Bank account balances or transactions | Requires consent or subpoena |
Medical records | Protected under HIPAA |
Emails or private social media messages | Illegal to hack or intercept |
GPS tracking without consent | Illegal in most states without owner’s approval |
Entry into private property | Considered trespassing, and criminal |
If a PI offers to “get into” someone’s phone, email, or home, that’s a red flag. It’s not only unethical, it’s illegal.
No. PIs cannot access call logs, text messages, or voicemails without consent or a court order. This is protected under the Electronic Communications Privacy Act (ECPA).
Not legally. Financial records are protected by federal banking laws. A PI can sometimes uncover visible financial clues (e.g., liens or bankruptcies) through public records but cannot access account balances or transactions without consent or subpoena.
No. PIs are restricted to publicly available information. Accessing private accounts, DMs, or deleted content would require hacking or unauthorized access, which is illegal.
Only if:
Otherwise, GPS tracking without permission is considered illegal surveillance in most states.
Yes, but only from public areas and as long as it doesn’t cross the line into harassment or trespassing. If surveillance becomes invasive or threatening, you have legal grounds to take action.
Private investigators are trained to uncover facts, but the best ones do it without crossing legal or ethical lines.
So, what information can a private investigator obtain?
They can:
But they can’t:
