Pre-Marital Investigations In and Around Delaware

Picking one’s partner is one of the most difficult things to do in one’s lifetime. We will go as in depth as you want into your partner’s history. Using our expert investigative skills to get to the truth so that you can move forward with confidence.

In Delaware, it seems that whoever gets to the court first has the upper hand. A married spouse can be living in their home one day and out the next day because of words on a paper. Given 30 minutes to pack your things and you may never return. If it’s truly justified then so-be-it. What if it’s not? What if your spouse has found a new love interest and they want to make things up in order to get you removed from the house? You think this can’t happen? It has happened and it does happen.

The courts are worried about the safety of the person who submitted the complaint. The courts are worried about not making the evening news. But what if the complainant is lying? What if the complainant drains the bank account on top of all else? Kicked out of your house, never to return AND no money to draw on.

You think this is impossible? It’s not! It can happen to you!
Know who you’re marrying!

Infidelity Investigations

Infidelity by its very nature is a sensitive issue. ABI Security Group takes this very seriously. The emotional and financial investment in relationships often grows over time as people make personal sacrifices, financial decisions and build their lives around each other. Not knowing where you stand and trying to plan your future when the lines of open and honest communication between you and your partner have broken down can be emotionally devastating and have long term financial consequences.

Being Discreet: You may think that your cheating spouse or significant other would never suspect that someone would be watching them! However, cheating can feel risky and exciting and watching over their shoulder is part of what they do. Other times, cheaters are absorbed and completely oblivious to their surroundings.

In the case of the vigilant cheater, it sometimes is necessary to engage more than one operative to get the job done efficiently and in a timely manner. This can increase the cost at first but by obtaining the evidence in a shorter time, it is ultimately less expensive. Surveillances done during rush hour traffic are especially more challenging and require more than one investigator on most difficult assignments.


If you are trying to establish infidelity and prove fault for purposes of gaining an advantage in a divorce action, ABI Security Group can assist you with obtaining the information that is necessary for your legal counsel to use in court proceedings.

Although some states have a “No Fault Divorce” law which does not require the evidence of adultery, there are still many states that proof is required. Also, some religious sects have regulations within their belief system where it is mandatory to document adultery. Even in “No Fault” states, proof of adultery can assist in the award of alimony.

In the State of Delaware it is beneficial for custody cases to have a “Judge of Character” of the other parent. We provide a detailed report prepared together with video footage and/or photographs, made available for any testimony that is required in future court appearances.

Child Custody & Child Support Investigations

Child custody matters are often required to be completed in a time sensitive way so that you, the client, can move forward in your case, with the benefit of knowing the real truth. This usually requires a skillful combination of surveillance and records checks culminating in court testimony in some cases. Whether you need clarification for personal reasons or for an ongoing court case, we can address these matters efficiently and with confidentially.

ABI Security Group leverages a broad range of resources for this important investigation. We not only provide database searches, but we can access the full weight of investigative techniques to determine the validity of documents filed with the Court.

These investigations can help determine the following:

  • Supervised visitation requirements are being adhered to
  • Activities occurring during child visitation periods are exposing children to risk
  • A parent associating with known criminals such as sex offenders
  • Domestic violence
  • Alcohol, drug abuse neglect
  • Verbal, emotional or physical abuse
  • Parent Alienation
  • Locate non-custodian parent to assist in enforcement of child support
  • Verification of employment and income

ABI Security Group is not your typical “PI Company”; we are experts in the field, so if your partner is street savvy and is an alert individual, you cannot afford to hire your “run-of-the-mill PI” because he will get caught. If an inexperienced PI gets caught then it’s over…you will likely never be able to have your partner followed again. We once followed a person for an entire year and never got caught. We handle difficult surveillances and have a 99% success rate when it comes to providing results without getting caught.

All of ABI Security Group Private Investigators and Detectives keep detailed and accurate notes. At the end of the investigation, these are transcribed and typed into a cohesive and understandable final Case Report, complete with details, times, places. If we have done video taping or taken still photographs, these will be presented to you along with your written report.

Sometimes, circumstances make it uncomfortable for our clients to actually receive these reports because of fears that they may be located and viewed by the Subject of the investigation. (In other words, if you suspect your husband of cheating, you may not want to have a ABI Security Group Investigations Surveillance Report in your home where your spouse may discover that you are having him followed.) We are happy to store all reports and investigative evidence gathered in our secure offices until they are needed for court or other purposes.

Technical Countermeasures & Bug Sweeps

When dealing with sensitive and proprietary information, it’s important to make every effort to ensure your privacy. Unfortunately, those with a motive to steal this confidential information are often clever and can hide listening devices and surveillance equipment in places where the layperson simply doesn’t think to look. That’s where a team of licensed private investigators steps in.

At ABI Security Group we take the privacy of our clients very seriously and are equipped to detect bugging devices as small as a dime. Our thorough bug sweep services are conducted using the most advanced countermeasure equipment available and leave no location or electronic systems un-inspected, so you can ensure that your home or place of business is indeed private. Our continuing education program provided by one of America’s top-rated countermeasure agencies ensures that our licensed private detectives keep up with the current technology.
