Cheaters

The show is taped mostly in North Texas around the Dallas/Fort Worth Metroplex as well as, to a lesser extent, the Greater Houston area. As of Late September 2009, Cheaters has started airing its tenth season of first-run episodes. A typical 30-minute Cheaters episode depicts a single complainant's case. A weekend edition of the show is also available, which runs 60 minutes and includes two separate cases.

The show's complainants can be either married or long-term significant others, and have included both opposite-sex and same-sex couples. It begins with a brief interview of the complainant, detailing how the complainant met their partner and what has led them to believe that the partner is cheating. Next, narrator Robert Magruder describes the progress of the investigation of the partner (referred to as "the suspect" during the episode), including surveillance footage of the suspect's actions with their alleged paramour (dubbed "the companion") recorded by the show's private investigators.
