New Jersey
New Jersey licenses private detective businesses through the State Police under the Private Detective Act of 1939, which was not amended from 2023 through October 2026. The changes that reach investigators came from privacy law: Daniel’s Law amendments, a consumer data privacy law, a 2026 data broker law with no investigator exemption, and a 2026 Supreme Court ruling on Daniel’s Law liability.

Changes, 2023 to 2026
Supreme Court: Daniel’s Law actual damages need no showing of a mental state
Answering a question certified by the Third Circuit, the Court held that Daniel’s Law does not contain a mental state requirement for actual damages liability under N.J.S.A. 56:8-166.1(c)(1).
For licensees: Liability for actual damages (at least $1,000 per violation) for disclosing a covered person’s protected information after a valid notice does not depend on proof of intent or negligence; punitive damages still require willful or reckless disregard of the law.
Data broker law with no investigator exemption
A data broker collects or buys personal data about consumers it has no direct relationship with and sells or licenses it to a third party; a data collector gathers data from consumers it deals with and sells it to data brokers (N.J.S.A. 56:8-166.20). Each must register with the Division of Consumer Affairs every year, paying from $5,000 to $1,500,000 depending on how many New Jersey consumers’ data it holds. No data broker or data collector may sell or license sensitive data, which includes precise geolocation (56:8-166.22), with penalties of $2,500 a day for failing to register and $50,000 per sensitive-data record sold. Publicly available information is excluded, and the exemptions do not name private detectives.
For licensees: An investigator who buys personal data about people it has no direct relationship with and resells or licenses it can meet the data broker definition, and many of the data vendors investigators buy from can be covered, subject to the act’s exemptions (for example, data governed by the FCRA or GLBA, and Motor Vehicle Commission data released under the DPPA).
Data privacy law exemptions amended
Rewrites the exemptions and definitions in the 2023 data privacy law, widening the existing health information and human-subjects research exemptions (to information treated like HIPAA-protected health information and to research under ICH good clinical practice guidelines) and adding insurance-support organizations and national securities associations. It adds no exemption for private detectives.
For licensees: No change in how the privacy law treats investigators.
Consumer data privacy law takes effect
Applies to businesses that control or process the personal data of at least 100,000 New Jersey consumers a year, or at least 25,000 while earning revenue or discounts from selling personal data (N.J.S.A. 56:8-166.5). It does not restrict complying with government investigations or subpoenas, or investigating, establishing, exercising, preparing for, or defending legal claims (56:8-166.15(a)). The Attorney General enforces it; there is no private right of action. None of the exemptions names private detectives.
For licensees: An agency is covered only if it meets one of the consumer thresholds.
New fingerprint archive fee
The State Police fee page lists a “New Archive Fee (January 1, 2025)” of $19.62 alongside the fingerprint fees for private detective applicants. The page does not say which applicants pay it or what authority sets it.
For licensees: Posted fingerprint costs now include a $19.62 archive fee.
Daniel’s Law amended: mandatory $1,000 minimum damages, assignee suits, and searchable databases
Section 6 amends N.J.S.A. 56:8-166.1, under which a person or business must stop disclosing a covered person’s home address or unpublished home telephone number within 10 business days of written notice. The covered person or an assignee may sue; the court shall award actual damages of at least $1,000 per violation; “disclose” includes making the information available in a searchable list or database; and “home telephone number” includes personal cell phones. It also changes “may award” to “shall award” and drops the requirement that a covered person first obtain approval from the Office of Information Privacy before sending a notice. The act also adds child protective investigators to the people covered.
For licensees: An investigator or agency that keeps a covered person’s home address or personal phone number available, including in a searchable database, more than 10 business days after a valid notice can be sued for at least $1,000 per violation.
