How to Find the Best Private Investigators in New Jersey

Choosing a PI involves more than looking at a website or reading online reviews. Here are important steps for vetting PIs to find the right one for your needs:

Verify Licensure and Credentials

Unlike some states, New Jersey requires licensure for private investigators. Check that a PI has an active license through New Jersey’s Division of Consumer Affairs.

This helps ensure they have undergone a criminal background check and met experience and education requirements. Licensure also means PI’s must adhere to ethical and legal standards.

Look for PIs with professional certifications like:

  • Certified Fraud Examiner (CFE)
  • Certified Law Enforcement Investigator (CLEI)
  • Criminal Defense Investigation Training Council (CDITC)


Membership in professional associations demonstrates credibility and commitment to ongoing training and education. Reputable groups include:

  • National Association of Legal Investigators (NALI)
  • National Council of Investigation and Security Services (NCISS)
  • New Jersey Licensed Private Detectives Association


Research Experience and Specializations

The best PI for your needs depends on experience that aligns with the type of investigation or case specifics. Look for PIs with expertise relevant to your situation, such as:

  • Infidelity – Surveillance, asset searches, social media and email hacking.
  • Personal injury – Interviewing witnesses, taking photographs and videos, reconstructing accident scenes.
  • Child custody – Conducting welfare checks, documenting activities and living conditions.
  • Workers compensation – Performing extensive background checks, verifying claims through surveillance.
  • Corporate investigations – Undercover assignments, intellectual property protections, due diligence.
  • Missing persons – Utilizing databases, online records and other sources to locate individuals.


Ask for References and Read Reviews

Ask the PI for references from past clients or attorneys they’ve worked with. Also check for online reviews on Google, Facebook or sites like the Better Business Bureau. This helps you assess their track record and read first-hand experiences from those who’ve used their services.


What to Expect When Hiring a Private Investigator

Private eyes aren’t just found in detective novels and movies. Here’s a realistic look at working with a PI:


Confidential Consultation

A reputable investigator will offer a free introductory consultation. This gives you an opportunity to explain your needs and ask questions.

The PI will also inquire about details (while avoiding information subject to attorney-client privilege). This allows them to assess the complexity of the case and resources needed to achieve your desired outcome.

Expect the consultation to take at least 30 minutes but sometimes up to an hour for involved cases. You can meet at the PI’s office or a location offering privacy and confidentiality.


Written Agreement

Any PI you hire should provide a written service agreement protecting both parties. This defines the scope of services, fees and billing practices, confidentiality standards, and other terms.

Never let a PI begin working simply on a verbal agreement. The contract gives you recourse if the PI fails to uphold their end professionally or ethically.


Investigation Plan

A reputable PI will explain their investigation process and plan based on the specifics of your case. This gives you a roadmap for what to expect as they work on your behalf.

For example, they may:

  • Outline records or resources to search for background information
  • Explain their surveillance approach and techniques
  • Describe how evidence will be collected, documented and preserved


Ask questions if any aspect of the investigation plan seems unclear or incomplete.


Ongoing Communication

Your PI should provide regular status updates as warranted by the nature of the case. For example, daily for a missing person versus weekly for an insurance claim investigation.

Communication methods usually include email, phone, video conferencing, and scheduled in-person meetings. This keeps you apprised of progress and any developments, without micromanaging day-to-day tasks.


Report of Findings

Upon completing the investigation, the PI should present a detailed report of activities performed, findings, evidence obtained (photos, statements, records, etc.), and their professional conclusions.

The report provides documentation if the information is needed for legal proceedings or insurance claims. Ask for a confidentiality agreement if the report contains sensitive information.


What Factors Determine Private Investigator Fees in New Jersey?

Unlike fictional TV detectives, real PIs don’t work for free. Their fees reflect the type of services provided and scope of the investigation. Common pricing factors include:

  • Number of hours – Rates range $50-$150 per hour or more.
  • Type of services – Surveillance demands more resources than database searches or interviews.
  • Travel requirements – Mileage and travel time to investigation locations.
  • Expenses – Any upfront or ongoing costs for data services, cameras, etc.
  • Rush requests – Higher priority investigations typically cost more.
  • Volume discounts – Established clients may receive reduced rates for ongoing needs.


Many PIs charge minimum fees such as a 4-hour base rate. They can also require retainers upfront, with additional fees billed monthly or upon completion. Get fee estimates and payment terms in writing upfront.


Laws and Limitations Governing Private Investigators in New Jersey

All PIs must operate within legal and ethical boundaries. It’s essential to choose an investigator who demonstrates integrity. Key regulations include:

  • Licensure – As mentioned earlier, New Jersey requires PIs to hold a license from the Division of Consumer Affairs.
  • Confidentiality – PIs must keep client information confidential, except by court order.
  • Surveillance – Cannot trespass or invade reasonable expectations of privacy.
  • GPS tracking – Requires consent of the vehicle’s owner or a court order.
  • Recording conversations – Allowed only with consent from one party being recorded.
  • Financial transactions – Cannot solicit or accept additional payments from other parties related to an investigation.


Understanding these limitations helps ensure you and the PI remain aboveboard. Unethical or illegal practices also render evidence inadmissible in court.


Questions to Ask

Vetting PIs thoroughly means asking the right questions upfront. This list covers key points to address:

  • Are you licensed in New Jersey? May I please see a copy of your license?
  • What professional affiliations or certifications do you hold?
  • How many years have you worked in private investigations and intelligence?
  • What types of cases and investigations are you most experienced with?
  • Who are your typical clients (individuals, attorneys, businesses, etc.)?
  • Do you have references I can contact, including from past clients?
  • Do you have experience testifying in court or providing reports?
  • How will you keep information about my case confidential?
  • Please explain your pricing and payment structures.
  • What is your availability to start on my case?
  • What differentiates you from other PIs? Why should I choose you?


Take notes on their responses, and follow up if they seem vague or concerning. A top-notch PI will welcome your thoughtful questions.


Finding the Right PI Matters

Don’t underestimate the importance of thoroughly vetting private investigators before hiring one. While cost and expediency might be tempting, a qualified PI is well worth the investment.

Choose a licensed investigator with proven expertise in the type of case you have. Look for stellar references, ethical practices, and clear communication every step of the way.

With the right private investigator handling your sensitive case, you can achieve the clarity, closure or justice you seek. Trust your instincts – if something seems amiss with a PI, it likely is. A professional investigator with integrity will respect your right to dig deeper in choosing who to entrust with your needs.


Should I only hire a private investigator that specializes in my type of case?
It’s wise to look for PIs with specific experience that matches your needs, whether that’s infidelity, insurance fraud, child custody, etc. Their expertise will lead to better results.
A skilled investigator will get quality evidence and results. But they cannot guarantee a specific outcome, like a settlement or court verdict. Manage your expectations.
Exceptionally low fees could signal inexperience or cutting corners. Be wary of rates well below average. But sometimes new PIs offer deals to build a client base.
Yes, a PI may decline a case if they feel it is unethical, illegal or unlikely to produce the results you want. Their priority should be professional integrity.
Definitely. It protects you if the PI makes errors or misses something critical. Reputable PIs carry E&O and other liability coverages.
