Family Law Investigations Surveillance and Investigations provide key information that can prove invaluable. When preparing for mediation or child custody hearings, utilizing licensed professional investigators can provide the attorney with pertinent information on their case such as neglect, child abuse, drug and alcohol related problems, established routines and who is spending time with the children. Investigations can also assist in documenting cohabitation and employment for cases where spousal support or maintenance are in question.


Corporate/Employee Misconduct Investigations - If you are a corporation in need of investigations for employee misconduct including drug and alcohol use, time theft, equipment theft, vehicle or equipment misuse, misuse of fuel or company credit cards and violations of non-competes, we will help you gather evidence to allow to take action.


Activity Checks – Activity Checks document a subject’s activities so you can determine if a more extensive surveillance would be beneficial.


Asset Checks – Asset Checks determine a subject’s financial status, which can help you decide whether or not litigation on another party would be worthwhile.


Background Investigations – Comprehensive Background Investigations assist the attorney in learning more about the subjects, witnesses and subject matter experts on their case.


Social Media Investigations – Social media posts, photos, conversations and status updates can provide valuable information about activities and subject matter in a case.


Witness Interviews – Witness interviews help you uncover information from potential witnesses that is critical for litigation and to support the facts for your case.


Witness and Beneficiary Locates – Our professional private investigators locate individuals who are needed for legal proceedings or to resolve estate matters.


Anti Stalking Investigations - Do you believe you're being physically stalked, cyber stalked, or harassed? Maybe you feel as if your reasonable expectation of privacy has been violated, or someone is trespassing onto your private property? Do you suspect a GPS tracking device has been placed on your vehicle without your knowledge or consent? Perhaps you have placed a restraining / protection order on someone, only to find that the restraining / protection order is not preventing the individual from violating it? Stalking and harassment is a growing problem. API provides consultations services and can incorporate surveillance, background investigations, locating of hidden GPS tracking devices, interviews and other services, providing you with the evidence you need to end this unwanted behavior.


Photography / Videography – Photography and videography services are available for clients who desire to document settings, conditions, environments, locations, etc. This service is differentiated from surveillance in that there is no video or photographs being obtained of a person or persons. Since there is no surveillance of a subject, this service is typically an overt service, whereas surveillance is always conducted in a covert manner. Some common requests for this type of service are for cases involving eminent domain, to document accident scenes, for premises liability defense, for questions of equipment manufacturing defects, and other types of defense investigations where supporting evidence is needed.
