Skiptracing (also skip tracing, or debtor and fugitive recovery) is the process of locating a person's whereabouts for any number of purposes. A skiptracer is someone who performs this task, which may be the person's primary occupation. The term "skip" (as a noun) refers to the person being searched for, and is derived from the idiomatic expression "to skip town", meaning to depart (perhaps in a rush), leaving minimal clues behind to "trace" the "skip" to a new location.
Skip tracing tactics may be employed by a debt collector, process server, bail bondsman or bail agency enforcer ( bounty hunters), repossession agent, private investigator, lawyer, police detective, journalist, or by any person attempting to locate a subject whose contact information is not immediately known. Similar techniques have also been utilized by investigators to locate witnesses in criminal trials.
