There are many ways a private investigator can assist with suspected infidelity in a family law case in Arizona. The investigator may take pictures or videos of the cheating behavior in action, or behavior that is suspicious and points toward infidelity. They will do a thorough online search to look for signs of infidelity on social media sites and dating websites, such as fake or hidden profiles. Once the investigator has completed their search, they will compile a detailed report of their findings, and may be asked to provide testimony in court regarding the evidence they uncovered.
