Who regulates private investigators in New Jersey
The New Jersey State Police Private Detective Unit licenses private detective businesses under N.J.S.A. 45:19-8 and following. The superintendent reviews each applicant’s character, competency and integrity, with a criminal history fingerprint check and a credit check.
New Jersey PI license types

How to get licensed in New Jersey: step by step
- Confirm you meet the age (25), U.S. citizenship and five-year experience requirements.
- Complete the application and background forms.
- Submit fingerprints and authorize the credit check.
- Obtain the $3,000 or $5,000 surety bond.
- Pay the $250 (individual) or $300 (other) fee by money order, cashier’s check, certified check or business check; no personal checks.
- Report changes in firm members, officers, directors or addresses within five days.
Carrying a firearm as a New Jersey investigator
New Jersey has very strict firearms laws. A private detective license doesn’t authorize carrying; you need the appropriate New Jersey permit and must follow State Police requirements.
What a private investigator in New Jersey can and can’t do
A PI license is a business license, not police authority. In New Jersey, as everywhere in the U.S., private investigators generally cannot:
- Impersonate law enforcement or claim official authority.
- Trespass on private property to watch or photograph someone.
- Obtain bank, phone or other protected records by pretexting, which federal law prohibits.
- Hack accounts, read someone else’s email or install spyware.
- Place a tracking device on a vehicle where state law forbids it.
- Detain or arrest anyone beyond the citizen’s arrest rights every person has.
On recording, New Jersey is not on the list of all-party consent states in a 2024 legal summary by the law firm Kilpatrick, which generally means one party to a conversation can record it. That does not allow recording conversations you are not part of, and other privacy laws still apply.
Who is eligible in New Jersey
The superintendent must be satisfied with the good character, competency and integrity of the applicant. N.J.S.A. 45:19-12 bars anyone under 25 and requires five years as an investigator or police officer with a New Jersey police department or a government investigative agency. For a firm or corporation, at least one member, officer or director must meet the experience rule. The State Police also require U.S. citizenship, references over age 21 and a credit check, and active police officers and government investigators cannot be licensed.
Costs, bond and term
The application fee is $250 for an individual and $300 for an LLC or corporation, paid to the State of New Jersey. The statute sets a surety bond of $3,000 for an individual and $5,000 for a firm, from a surety authorized in New Jersey and approved by the State Police. Do not buy it until the Private Detective Unit instructs you to.
The statute gives a two-year license term with renewal fees of $200 for an individual and $250 for a firm, per location. We read it on an unofficial reproduction that may lag the current text, so confirm renewal amounts with the State Police.
