In order to become legally wed in the State of New York, the wedding couple must apply in person for a marriage license. It cannot be done by mail, and you may not send a representative in your place. The couple may visit any town or city clerk within the state and the license is valid for any location within the state, not just within the town or city limits where license was obtained. So, if you live in Manhattan, for instance, you may go to the New York City Clerk to obtain the license, and bring it with you to your ceremony location for your officiant to complete and sign.
