Long Island investigation work.

From Nassau County's wealthy North Shore to Suffolk County's East End, NYIA has worked Long Island cases for over three decades.

Long Island generates investigation work that's distinct from the city. Matrimonial cases on the North Shore involve substantial estate properties and family money. Suffolk County's working waterfronts produce a different kind of caseload. Boating community surveillance, marine business investigations, and the insurance and disability work that follows from physical industries.

Our Long Island work is dispatched from our Manhattan office and supported by Nassau- and Suffolk based field investigators. Civil and matrimonial work runs primarily through Nassau County Supreme Court in Mineola and Suffolk County Supreme Court in Riverhead.
