Private investigators provide a wide range of services, but perhaps the most well-known are those involving finding out if a spouse is cheating. The following are a few of the cheating investigation services and techniques that we use to uncover the truth about your suspicions.


If a private investigator has good information about where your spouse is likely to be with their lover, often we can sit and wait for them to arrive. This may be at a favorite restaurant or perhaps in a residential area. Whatever the case may be, a private investigator knows the best places to observe and record any compromising behavior using video or photography.

Of course, this type of behavior must be in a public place to be legally recorded. But that’s usually easier than it sounds as it’s surprising how fast people let their guard down when think they are not being watched.

Investigating Credit Card Receipts

Gathering information about your spouse is something that needs to be done. One area to start with is credit card statements. Often a spouse will charge a dinner or lunch with someone he or she is having an affair with. If confronted about it, there is often a logical explanation.

We can find out more information than what is listed on a credit card statement. The same is true with other odd charges on a credit card. This type of investigative work can also be done to find hidden assets.

Investigating Emails and Phone Calls

Whether we can read your spouse’s emails or look at their phone logs legally will depend on a few factors, but if it is legal we can investigate any suspicions you may have. Once we have more information, we may then need to do some field work and follow your spouse to see if they are meeting with the person your spouse is communicating with, and then determine the nature of their relationship.

Global Positioning System Tracking

There are two basic ways you can use a GPS device to track the movements of your spouse. One is to use a device that attaches to your spouse’s car to track it’s movements. Knowing the location of their vehicle is important information.

Another way to track your spouse is with their smartphone. Various apps can be installed that turns the smartphone into a tracking device. This will tell you exactly where the smartphone is, but not necessarily where your spouse is. The phone will also need to be on for this to work.

The services listed above are only a broad outline of what a professional private investigator can do. Keep in mind, that the services listed above are only legal under certain circumstances. This is one reason to use a licensed professional. Contact our firm today, and explain to us why you suspect your spouse of infidelity, and we can tell you how our services apply to your specific circumstance.
