Hiring a private investigator can feel overwhelming if you don't know what to expect, what they can actually do, or how much it will cost. Whether you're dealing with infidelity suspicions, background checks, or asset searches, understanding the basics will help you make a smarter decision. Here's what you need to know before bringing an investigator on board.
What Services Do Private Investigators Actually Provide?
Private investigators handle a surprisingly wide range of cases. Common services include infidelity investigations, skip tracing (locating missing persons), background checks, surveillance, fraud investigations, and due diligence for business transactions. Some specialize in areas like workers' compensation fraud, divorce proceedings, or corporate espionage. When you're comparing options, check whether an investigator has experience with your specific case type—someone brilliant at asset discovery may not be the best choice for surveillance work.
How Much Does a Private Investigator Cost?
Pricing varies significantly by location, complexity, and the investigator's experience level. Most charge either hourly rates or flat fees. Hourly rates typically range from $50 to $200+ depending on the region and investigator credentials. A straightforward background check might cost $300–$800, while active surveillance can run $1,500–$5,000+ per week. Don't assume the cheapest option is the best—you're paying for their expertise, resources, and access to databases. Always ask for a written estimate upfront.
What Licensing and Credentials Matter?
This is critical. All legitimate private investigators must be licensed in their state—there are no exceptions. Ask to see their license and verify it through your state's licensing board. Many carry additional certifications like:
- Certified Investigations Professional (CIP)
- Professional Certified Investigator (PCI)
- Association of Certified Financial Crime Specialists membership
- Industry-specific credentials (e.g., fraud examiner certifications)
Don't hire someone who can't produce documentation. Unlicensed investigators expose you to legal liability and unreliable work.
How Long Does an Investigation Take?
Timeline depends entirely on the investigation type. A background check takes 3–7 business days. Locating a missing person might take weeks or only hours if they're findable through public records. Infidelity cases can span 2–4 weeks of surveillance, though some situations resolve faster. Complex fraud investigations may take months. Be wary of anyone promising instant results—if they do, they're likely cutting corners on quality.
Can a Private Investigator Access Private Information?
Not legally. Legitimate investigators cannot hack emails, access sealed records, intercept communications, or break into accounts. They work with public records databases, courthouse documents, property records, and observation. They also follow strict laws around surveillance—for example, they can't trespass, photograph you through bedroom windows, or record conversations without consent in two-party consent states. Understanding these boundaries protects both you and the investigator.
What Should You Look For When Hiring?
Start by checking references and reading verified reviews. A reputable investigator should willingly provide past client testimonials and be transparent about methods. During your initial conversation, notice whether they ask detailed questions about your case. If they're vague about how they'll proceed or what they can deliver, that's a red flag. You should also feel comfortable with their communication style and responsiveness—you'll want regular updates.
Using a comparison platform like Mercoly makes it easier to review multiple investigators side-by-side, read genuine customer feedback, and find licensed professionals in your area without doing hours of research yourself.
Do You Need a Lawyer Too?
Often, yes. If your case involves custody disputes, criminal matters, or legal proceedings, having both an investigator and attorney ensures your evidence is gathered legally and presented properly. Many attorneys have investigator referrals they trust. If you're going solo on a personal matter (like infidelity), an investigator alone may be sufficient, though consulting a family law attorney beforehand is wise.

Q: Will a private investigator's evidence hold up in court? Only if it's gathered legally and documented properly. Make sure your investigator understands the rules of evidence in your state and provides detailed reports with timestamps, photos, and witness statements when applicable.
Q: How do I know if an investigator is operating legally? Verify their state license, ask about their training in privacy law and surveillance regulations, and never accept a proposal involving illegal activities. Legitimate investigators follow strict guidelines.
