Hi Bob, I live in Martinsburg, West Virginia and the address that you want is the Courthouse which is located on King Street. The phone book does not give an address, all it gives is the phone number. Martinsburgs, downtown is not that large so it would reach them if you addressed it Berkeley County Courthouse, King Street, Martinsburg, West Virginia 25401 Here is the phone number as well....304-264-1927, that number is to the County Clerks Office. If i can be of any other assistance to you just email me [email protected] Vickey PS, if you do want a more accurate address I could call them myself and get it for you.
