Step 1: Confirm the New York State License

In New York, no one can legally work as a private investigator, or even advertise as one, without a license from the New York Department of State. This is required by Article 7 of the General Business Law.

A license tells you a lot. To qualify, an investigator must:

• Be at least 25 years old
• Pass the state private investigator exam
• Have at least three years of qualifying investigative experience, or 20 years as a police officer
• Be fingerprinted and pass a background check
• Carry a $10,000 surety bond

How to check a license: Use the Department of State’s free online Licensee Search. One detail trips people up: New York lists private investigator licenses under the business name or license number, not the investigator’s personal name. If you search for a person’s name and find nothing, search the company name instead.

Any investigator should give you their license number without hesitation. Ours is NYS License No. 11000222158.

Step 2: Match the Investigator’s Experience to Your Case

A license is the minimum. Experience is what gets results.

Investigations are not all alike. Surveillance for an insurance claim takes different skills than locating a missing witness or reviewing an old criminal case. Ask what kinds of cases the investigator handles most often, and how many cases like yours they have worked.

Pay close attention to courtroom experience. If there is any chance your case ends up in front of a judge, your investigator may have to testify. An investigator who has never been cross-examined is learning on your case. Our founder has testified in court hundreds of times, and every report we write is prepared with that in mind.

Step 3: Make Sure They Work Within the Law

A good investigator knows exactly where the legal lines are. An investigator who crosses them can hurt your case and expose you to legal risk.

Recording conversations. New York is a one-party consent state. Under Penal Law Section 250.05, recording a phone call or conversation is a crime unless at least one person in it agrees. An investigator cannot secretly record a conversation they are not part of.

Illegal evidence gets thrown out. Under New York’s Civil Practice Law and Rules Section 4506, recordings made through illegal eavesdropping generally cannot be used as evidence in court, including in family court and civil cases. Evidence gathered the wrong way can do more harm than good.

No posing as police. State rules make it unlawful for a licensed investigator to say anything that would make someone believe they are a police officer or government investigator.

If an investigator promises to get your spouse’s text messages, hack an email account or “do whatever it takes,” walk away. That is not confidence. It is a liability.

Step 4: Ask How Findings Are Documented

The result of an investigation is only as useful as the report that comes with it. Before you hire anyone, ask:

• Will I get a written report?
• Do photos and video include dates and times?
• Is the report written so an attorney or judge can rely on it?
• How often will you update me while the case is open?

Clear, factual reports matter most when the findings are disputed. In our experience, the strongest reports simply state what was observed, when and where, without opinion or exaggeration.

Step 5: Understand the Cost Before Work Begins

Private investigation in New York is usually billed in one of three ways:

• Hourly rates for surveillance, interviews and research
• A retainer paid up front and billed against as work is done
• Flat fees for defined tasks, such as some background checks

Mileage, database searches and other expenses may be billed separately. Ask for a written estimate and a written agreement before any work starts.

Be cautious of the lowest quote. A cheap investigation that misses the key moment, or that cannot hold up in court, costs more in the end.

What to Have Ready Before You Call

You will get a faster, more accurate estimate if you have:

• The names of the people involved and any known addresses
• Photos and vehicle descriptions, if relevant
• Known schedules or patterns
• Any court dates or deadlines
• Your attorney’s contact information, if you have one

You do not need everything on this list. A good investigator will help you figure out what matters.

8 Questions to Ask Before You Hire a Private Investigator

• What is your New York license number?
• How many cases like mine have you handled?
• Have you testified in court, and how often?
• Who will actually work my case: you, or someone else?
• How will you keep my case confidential?
• What will the report include?
• How do you bill, and what expenses should I expect?
• What results are realistic for a case like mine?

Red Flags to Watch For

• No license number, or reluctance to share it
• Guaranteed results (“I’ll prove he’s cheating”)
• Offers to access phone records, bank records, texts or email
• Pressure to pay large sums in cash with no written agreement
• Vague answers about who will do the work
