Is Your Partner Cheating?

Statistics show that 30% to 60% of marriages experience infidelity at some point. This is a common issue in relationships, but its “popularity” doesn’t make it easier to accept it. Some of the most common signs of infidelity include suspicious phone habits, decreased affection levels, a lack of intimacy, or changes in grooming habits. And, of course, the sudden need for extra hours at work.


If you suspect your partner is unfaithful and want to hire a private detective to provide evidence of infidelity or, hopefully, to report back that your suspicions have no foundation in reality, hire one of our infidelity investigators.


Work with a professional investigator who knows how to handle such delicate matters and understands that cheating investigations need tact, discretion, and experience. If you are married, things get even more complicated. Opening a matrimonial investigation is often a difficult decision for the spouse who believes something is amiss with their partner.

How to Catch a Cheater in Chicago, IL

When considering hiring an infidelity investigator, we ask that you consider your end goal. You must decide your next steps if the marital investigation proves that your suspicions were founded and you have an unfaithful spouse.


The information we provide can become admissible evidence of adultery. Are you ready to take this step? Or are you willing to try and fix your relationship despite marital infidelity and the evidence of wrongdoing resulting from the adultery investigation?


To catch a cheater could be as simple as placing a GPS on their vehicle to confirm their movement or it might require long periods of in-person covert surveillance. During your initial consultation with one of our infidelity private investigators, we will let you know what resources we have and what investigative services we can provide.
