Bergen, Hudson & Passaic — investigated by people who know the territory

Cop Call is a New Jersey private investigation firm based in Montvale, in the heart of Bergen County. We focus on Northern New Jersey — Bergen, Hudson, and Passaic counties, with coverage extending into Essex and Morris — because investigations go better when the investigator knows the ground. We work cases from Hackensack and Paramus to Hoboken and Jersey City, and from Clifton and Paterson out to the towns along the county lines.

We are not a national directory that sells your inquiry to the nearest bidder. When you call (201) 345-2124, you reach a licensed investigator who works here.

Private investigation services across Northern NJ

Every engagement is handled by a licensed investigator and documented to court-admissible standards. These are the services Northern New Jersey clients and attorneys retain us for most often.

Surveillance.

Discreet, court-admissible physical surveillance with high-resolution photo and video documentation — for personal, family-law, and corporate matters.

Infidelity Investigations

When you need to know the truth about a spouse or partner — documented discreetly, lawfully, and in a form that holds up if you decide to act on it.

Child Custody Investigations

Court-admissible documentation for custody and parenting-time matters, prepared to the standard New Jersey family courts expect.

Background Checks

Source-of-truth background investigations for employers, attorneys, landlords, and individuals — far beyond what online lookup tools deliver.

Asset Searches

Locating and documenting assets for litigation support, judgment recovery, divorce, and due diligence.

Salary Investigations

Verifying income and employment for support, litigation, and due-diligence matters where an accurate earnings picture matters.

For New Jersey attorneys and their clients

Family-law and litigation attorneys across Northern New Jersey refer their clients to Cop Call because our work is built to survive scrutiny. Every observation is timestamped, every photograph carries its metadata, and every chain of custody is documented from the field to the final report — and our investigators are available to testify as fact witnesses when a matter proceeds to court.

Whether you’re an attorney building a case or an individual who simply needs to know, the standard is the same: lawful methods, careful documentation, and complete discretion. If you have an attorney, we coordinate with them. If you don’t yet, your final report will be ready for the one you hire.

Why Northern New Jersey chooses Cop Call

Licensed & bonded in New Jersey — We operate under New Jersey Private Investigator License #9525 — and are also licensed in New York (#11000188552). In a regulated field, that license is the difference between evidence that stands and evidence that gets challenged.
A Northern NJ firm — 35+ years of casework in this region, led by investigators with decades of prior law-enforcement experience. We know how Bergen, Hudson, and Passaic matters tend to unfold.
Court-admissible by default — We document every case as though it will be filed as exhibits — because it often is. Lawful methods only; nothing that could get your evidence thrown out.
Discretion is the entire point — Unmarked vehicles, careful methods, and a discreet number when we contact you. If we ever believe an investigation has been compromised, we tell you.

Northern New Jersey PI — frequently asked questions

What areas of Northern New Jersey does Cop Call serve?

Cop Call serves Northern New Jersey — primarily Bergen, Hudson, and Passaic counties, with coverage extending into Essex and Morris. Our New Jersey office is in Montvale, in Bergen County, and we work cases throughout the region, from Hackensack to Jersey City. We are a locally based, licensed New Jersey private investigation firm — not a national lead-generation directory.

Is Cop Call a licensed private investigator in New Jersey?

Yes. Cop Call is a licensed and bonded New Jersey private investigator operating under New Jersey Private Investigator License #9525, and has been in business since 2004. The firm is also licensed in New York (License #11000188552). In New Jersey, hiring a properly licensed investigator matters because evidence gathered by an unlicensed individual can be challenged.

What private investigation services do you offer in Northern NJ?

Cop Call provides surveillance, infidelity investigations, child custody investigations, background checks, asset searches, and salary investigations throughout Northern New Jersey. Each engagement is handled by a licensed investigator and documented to court-admissible standards. Tell us your situation during the free consultation and we will tell you honestly whether an investigation can help.

Can the evidence hold up in a New Jersey court?

Yes. Surveillance reports, photo and video documentation, timestamped activity logs, and investigator testimony are prepared to the evidentiary standards used in New Jersey family and civil courts. Cop Call works alongside New Jersey attorneys regularly and gathers evidence only through lawful methods, because evidence obtained unlawfully can be excluded and can damage a case.

How much does a private investigator cost in New Jersey?

Cost depends entirely on the scope of the case — what is being documented, the location, the duration, and the number of investigators required. Cop Call works on flat-fee or capped-budget engagements rather than open-ended hourly billing. The specific range for your situation is provided during your free, confidential consultation, before you commit to anything.
