Investigation coverage across all 40 Westchester villages, towns, and cities. From Yonkers in the south to the Putnam County line, from the Hudson River to the Connecticut border.
From Scarsdale matrimonial cases to Bedford estate work, from White Plains corporate surveillance to Yonkers urban investigations. New York Intelligence Agency has operated across Westchester County for over three decades.
Westchester is one of the wealthiest counties in the United States and one of the most varied. The communities range from dense urban Yonkers and Mount Vernon at the southern border, through the wealthy commuter villages of Scarsdale and Bronxville, to the country estates of Bedford and Pound Ridge in the north. Effective investigation across this geography needs investigators who know the difference and operate accordingly.
Most of our Westchester caseload involves matrimonial work. Complex divorces among finance, legal, and medical professionals who live in Westchester and commute to Manhattan. We also handle corporate surveillance for the substantial Westchester corporate community (MasterCard in Buy, IBM in Armonk, PepsiCo in Buy, and many others), counter surveillance and TSCM for executives, and complex financial and family law cases throughout the county.
Civil and matrimonial matters arising from our Westchester work typically run through the Westchester County Supreme Court at 111 Dr. Martin Luther King Jr. Boulevard in White Plains. Family court matters run through the Westchester County Family Court at the same address. Our reports are written for use by Westchester matrimonial and litigation attorneys, and our investigators have testified in Westchester court many times.
