About us

CBI History and Background

CBI was founded in 1990. Headquartered in Massachusetts, our organization services the Northeast. We are licensed in Massachusetts, Rhode Island, Connecticut, and New Hampshire.

CBI is a superior investigation company that conducts criminal, civil, and domestic/personal investigations. We also specialize in insurance investigations including disability, workers’ compensation, and liability to determine compensability over most of New England.

Our Director of Investigations is trained in litigation and is responsible for Quality Control oversight on all cases.

For over 20 years, we have successfully worked cases with many being denied due to our investigations. Numerous cases have lead to convictions of fraud including high-profile cases with state and city municipalities.

We price our services competitively and only bill for on-site surveillance time. This means whatever time you assign us is used on-site for surveillance and is not allocated for travel time.

CBI is a SOMWBA certified business since 2006. Being women owned and operated complies with state and federal regulations in subcontracting for the AMP Executive Order 390.


“CBI has been a valued partner for investigations in my work

With the Commonwealth of Massachusetts Human Resources

And with Massport Authority for over twelve years.

CBI brought two cases to fraud and conviction

When I was at Human Resources.”

Our Surveillance Capabilities Can Handle Even the Most Difficult Cases

Our surveillance is enhanced by powerful technology. We have invested in the most advanced High-Definition digital camcorders with time and date stamp and strong zoom capability, body-worn equipment including pinhole hidden cameras, and night vision. As an innovator in the industry, CBI has designed and custom built covert static cameras that can be deployed in any environment for up to two weeks.

Video Output ~ We place a strong emphasis on video footage. Our video ratio is amongst the highest in the industry. This high ratio plays a critical role in producing evidence that is valuable to you. We can provide you with video in any format necessary including .wmv, which is required by the Department of Industrial Accidents in order to be submitted as evidence.

Detailed Report ~ All of our surveillance is accompanied by a chronological report that details the claimant’s physical abilities, environment, behavior, hobbies, activities, interactions, and appearance. The alleged injury is the focal point of both the report and video footage.

We Keep You Updated Throughout the Investigation

We have built our reputation on a policy of strong communication. Investigators work closely with CBI’s Director of Investigations, who oversees every case. Our dedicated staff is available to answer any of your questions and will send updates the day after surveillance was conducted. We guarantee prompt and courteous service.

Our Director of Investigations is trained in both litigation and investigations. He is responsible for preparing and reviewing all client reports. As your point of liaison, he will keep you updated on your investigation and make recommendations as needed.

For discretionary purposes and added value, our Account Representative is available to hand deliver and review your report with you upon completion of an investigation.

Seasoned Investigators Who Are Discreet and Results Driven

Many of our investigators have been with CBI for many years. We have a very low turnover rate. We operate by a strict ethical code and only recruit individuals who are professional. All CBI investigators receive ongoing training in order to exceed industry standards.

Each investigator operates out of his or her local area, which inherently results in the investigator having intimate knowledge of shortcuts, restaurants, supermarkets, golf courses, gyms, etc.

They come from a variety of backgrounds and are representative of the population at large. Our investigators are able to blend into a variety of environments and avoid detection.

Our investigators treat claimants, witnesses, and all other third parties with courtesy. Should your claim go to court, you can be sure he or she will be well prepared, neat, and exhibit proper courtroom decorum.

What Makes our Investigators Outstanding?

Our investigators are detail oriented. They are able to think outside the box and can make important decisions as situations unfold. All of this is critical for staying one step ahead of savvy claimants who may be trying to take advantage of the system.

Our investigators take pride in the success of their work. They use all of their resources to obtain these results.

Our quality investigators have built their reputation by successfully handling the diverse needs of our clients.

Attorney Services

Helping you help your clients

There are countless reasons why an attorney would want to hire a legal private investigator. The most basic reason is that most attorneys and law firms simply do not have the time and resources to conduct a thorough investigation, find and interview potential witnesses, seek and uncover evidence that could be pertinent to proving their client's case, all in addition to preparing their case and getting their client ready to appear in court. The most effective and efficient way to improve your chances of obtaining the positive outcome your client is counting on you to deliver, is to hire a skilled private investigator to work on your behalf.

Our job as your investigators is to obtain the information you need in a timely fashion. We understand that by referring your client to us, you are extending your own credibility to us. We take the responsibility of representing you and your reputation very seriously and always handle your client’s case professionally, ethically, and tenaciously.

As an attorney, you have very specific needs. We are well equipped to handle whatever needs you may have. The following are some common services we have provided to attorneys:


  • Surveillance
  • Driving/RMV Records
  • Recorded/Signed Statements
  • Criminal/Background Investigations
  • Locate Investigations
  • Financial and Asset Investigations
  • Phone Traces
  • Scarring Photos
  • Cohabitation Investigations
  • Infidelity Investigations
  • Social Media Searches


Nothing does a better job of demonstrating the truth than video. When your case involves an individual engaged in some behavior they deny doing or are prohibited from doing, we get it on video for you. From insurance fraud to violations of non-compete agreements, we can cover it.

Locating Witnesses

There is a large variety of Internet based search tools and paid information services available to attempt to locate a witness. Combining this with our investigative skills and experience, we specialize in locating witnesses.

Interviewing & Statement Taking

At CBI, our investigators who take statements have been professionally trained to work with witnesses to determine what they know and obtain the most relevant information.

Asset Searches

Successfully obtaining a judgment for your client is critical. Knowing what assets are available is paramount to obtaining a judgment. That’s where we come in. We assist attorneys and their clients in determining if their opposition has assets to collect upon, if they are already encumbered, or where they are trying to hide them.

Accident Scene Investigations

A CBI private investigator will photograph, measure and diagram the scene from all angles, document traffic light timing, and conduct a neighborhood canvass to identify any witnesses. These investigations can be conducted at the same time of day, with the same weather conditions, to assure accuracy. Photos of the scene during similar conditions will provide you with the best insight.

Background Checks

Having all the facts can make or break your pleadings, deposition, and even your case. Our private investigators will dig deep to find out a person’s true background. When you need the truth, CBI can find it.

CBI has access to proprietary databases, which allow us to conduct nationwide background searches. These database searches include but are not limited to:

  • Real Property
  • Social Media
  • Liens and Judgments
  • Corporate Filings
  • Relatives

We encourage you to contact us to discuss how we may be of service to you.

Tell-tale Signs of A Cheating Spouse

The following is a guide to help you determine if your partner is cheating on you. Do not confront the cheater or use this guide as fact. Consult a professional. It will only make it more difficult for you to catch them when you may not have enough proof yet to make your case.

  1. At the beginning of an affair the cheating partner may be more attentive to his spouse due to guilt.
  2. The cheater later finds fault with the person he/she may be living with to try to justify the affair.
  3. Intuition that something is not right usually is a sign you may have a cheating problem.
  4. Cheaters may have a change in sex life (i.e., more sex, less sex) as well as unexplained sexual requests.
  5. The cheater has a definite change in attitude towards everyone in the home, especially the partner.
  6. Grooming habits will change. Cheaters will be more attentive to their appearance. For example, they may buy new clothes, join a gym, or cut their hair more often.
  7. You may want to monitor your spouse for two weeks. During this time keep track of the mileage on their car. Monitor the time they leave for work and the time they come home. If your mate claims to be working late, check paycheck stubs to verify this overtime.
  8. Be tuned in to home telephone calls when your mate has a tendency to whisper or gives a quick answer and immediately hangs up or when you answer the telephone and get an abrupt hang up.
  9. Your partner may have recently added password protection on their phone and/or computer.
  10. Your partner may spend more time outside of the home and make excuses as to why they need to do so. For example, they may say they are working late or going out with friends.

  • Criminal/Background Searches
  • Locate Investigations
  • Financial and Asset Investigations
  • Phone Traces
  • Cohabitation Investigations
  • Infidelity Investigations
  • Alimony/Child Support

Cohabitation Services

Over 4 million households in the United States account for unmarried couples. In the State of Massachusetts, the Alimony Limitation Law proceeds as follows:

The Massachusetts Alimony Limitation Law: Passed on March 12, 2012

The Alimony Reform Act (Chapter 124 of the Acts of 2011) reads in part...

Chapter 124 of the Acts of 2011

  1. Cohabitation Suspends, Reduces, or Terminates Alimony
    "General Term Alimony shall be suspended, reduced or terminated upon the cohabitation of the recipient spouse when the payer shows that the recipient has maintained a common household with another person for a continuous period of at least three months."

When determining if the recipient is maintaining a common household, the court may consider any of the following factors:

  1. Oral or written statements or representations made to third parties regarding the relationship of the persons;
  2. The economic interdependence of the couple or economic dependence of one person on the other;
  3. The persons engaging in conduct and collaborative roles in furtherance of their life together.
  4. The benefit in the life of either or both of the persons from their relationship;
  5. The community reputation of the persons as a couple, or other relevant and material factors.

The state of Massachusetts is a "no-fault" state. Therefore the cause of divorce does not matter; assets and property are split equally. Apart from this, child custody, child support, and alimony depend on the parents' activities.

For example, in the state of Massachusetts, if a divorce occurs, and then the wife begins cohabitating with another man, both the wife and the person with which she is cohabitating is held responsible. Proof of cohabitation is a necessity in court to assist in child custody, compensation claims for child support, and alimony matters. All the facts that CBI’s Cohabitation Surveillance Investigators recover will be admissible in court in a well fashioned, clear manner.

If your ex-spouse is residing or cohabitating with an adult, you may have justification to decrease the amount you are paying in support. Our clients want to know whether they're supporting their former partner alone or their former partner and someone living with their former partner. If your former partner is co-habitating, questions start to arise about how much money you should be paying a former spouse in alimony. Evidence can be obtained to prove this permanent residential arrangement, and you could benefit from the results of CBI’s Cohabitation Surveillance results.

In preparing to bring an alimony reduction matter before the court, you must prove cohabitation of the ex-spouse first.

CBI is especially well suited and has already begun performing these types of investigations due to the nature of our business. We are able to perform periodic “spot check” investigations at different times of the day over a period of 3 to 4 months in order to establish a pattern and prove beyond a reasonable doubt that the recipient is maintaining a common household and “Co-Habitating”. All “spot checks” are video taped and preserved as evidence. Our investigators are skilled at stationary and mobile surveillance operations and perform surveillance on a daily basis. We have access to credit bureaus and national databases as well that can aide us in our investigation. Should you feel that we may be able to assist you in matters of Co-Habitation, please do not hesitate to contact us with any questions
