Welcome from County Clerk Maureen O'Connell

I am delighted that you have chosen to visit the County Clerk’s online office.

The County Clerk is an office created by the New York State Constitution, serving as Clerk of the Supreme and County Courts and as an agent for state and federal governments. In addition, the Clerk is responsible for recording documents relating to real property located in Nassau County and maintains the official index of real property ownership.

As County Clerk, my primary objective is to continue to implement strategies to promote real-time services and facilitate enhanced access to serve the residents of Nassau County. We constantly are working to strip away layers of bureaucracy, improve access to official records, and streamline operations while containing costs.

The Nassau County Clerk’s Office offers a variety of services to assist the courts, legal professionals, and the public. We process hundreds of millions of dollars per year in transactions and have many statutory duties. I hope our website is informative and that this office processes your transaction to your satisfaction.
