Whether it is a cheating spouse, a child custody dispute, or a business partner who has been stealing from you for years—investigating these issues can help us get closure and solve problems. But what if you don't have time to do your own investigating? When that situation arises, then hiring a private investigator may be the answer. Private investigators have been trained in techniques such as surveillance and evidence gathering to uncover any hidden information about their subjects of inquiry. In addition to solving major life puzzles with investigations, they also serve as expert witnesses in court proceedings related to criminal law cases and civil lawsuits involving fraud or breach of contract disputes between business partners.
