The After Hours Box is intended as a convenience. It is not intended as an alternative for filing papers during regular business hours. Filings may be placed in the after hours box after 4:00 p.m. Monday through Friday (except holidays). Filings placed in the box will be "date stamped" the day they are deposited. The box in Baltimore will remain open until midnight. Because of security concerns, the box in Greenbelt will be open only until 7:00 p.m.  These hours may be changed without notice because of security concerns.
