Why Choose Magnum Investigations

IMPORTANT: There are many companies offering Investigative Services who are NOT Licensed Investigators and are therefore operating illegally. Therefore be careful and demand that the company provide you with their License Number and then verify it through New Jersey at (609) 633-9352 or New York at (212) 417-5800; in PA you must contact the Clerk of Courts in the County where the company claims to be located.

Surveillance specialists trained to remain undetected.

If you hire a private investigator to catch your cheating spouse, you can’t afford for the investigator to get caught. Most other companies are one-man operations and generally get caught.
