Child Custody

In a custody case, the best interests of the child are most important. Cornerstone Private Investigators will provide unbiased information about the behavior of the parent and the living conditions provided for the child. If you have suspicions about either, talk to your family lawyer first—then call us.


Going through a divorce can be one of the most difficult things you’ll ever do. A private investigator can make the process easier by uncovering the truth about your spouse’s behaviors. Cornerstone Private Investigators offers discreet surveillance services that will provide the proof you need.

General Private Investigation Services

When you have to know the truth, it’s time to call a private investigator. Private investigators are highly trained professionals with experience in tracking down the answers you need. Cornerstone Private Investigators will talk to you about the details of your case and offer our expert recommendations on the best steps to take.

Criminal Defense

Have you been charged with a crime? You’ll want to make sure the true facts of the case are presented to the court. Our private investigators will collect evidence, talk to witnesses, and be an impartial voice. Let us help you tell your side of the story.


Private investigators are trained in surveillance techniques for many purposes. Surveillance can be used to prove that a spouse is cheating, find someone who’s missing, or to prove or disprove the accuracy of an insurance or workers’ compensation claim. If you need to know the truth, we’ll help you discover it.

GPS Tracking

GPS tracking can be used to prove a person’s whereabouts at a particular time, as well as their driving behavior. However, there are many legalities involved in using this technology. Licensed PIs like those at Cornerstone Private Investigators know the laws and will advise you accordingly.


Adultery is when a married person cheats on his or her spouse. While the mere suspicion of adultery is painful, you need to know the truth—especially if you plan to take legal action. Our investigators will impartially find and examine the evidence, then pass it along to the courts if needed.
