A polygraph measures and records physiological responses when a subject is asked and answers a series of questions. The theory is that the polygraph will produce a change in measurement should a false answer be provided.
Polygraph examinations are not regarded in the UK as evidentially sound. However, they do offer some indicators in cases that involve sexual abuse allegations, for example. In such cases, Family Court Support makes polygraph exams a precondition when considering taking on the case.
If you believe a polygraph test would benefit your case, Family Court Support can arrange polygraph services though an experienced third party.
