Also known as the Lie Detector Test is a quick and simple way of finding out the truth. The person undergoing the test is asked some preliminary questions before the actual tests begin. The Polygraph test reads the body’s reaction to certain questions when asked and will detect irregularities in the body’s physical response when a “lie” is told. So far, Polygraph testing has been used in our pre-marital and infidelity cases, along with some corporate investigations.

Asking “have you ever slept with anyone else whilst with your spouse?” has proven to be a very popular question…is this something you need answering quickly?
