The New York State Courts Electronic Filing (NYSCEF) System permits the service and filing of litigation papers with the county clerk or the court by a registered user, by electronic means on its website at www.nycourts.gov/efile. The advantage of being a NYSCEF user is that attorneys can serve and file papers at any time. A case can be initiated or post-commencement modification or enforcement proceedings can be filed at any hour of any day, even when the courts are closed.
