Ken is wrong, there are no land records filed in the Kings County Clerk's office. All land records are filed across the street at 210 Joralemon St. 2nd floor in the Registers office. You can also obtain a copy of your deed online. Just Google "ACRIS" and it will be the first result. The search by address etc.
You can go to the County Clerk at Room 189 in Kings County Supreme Court - You can look at the computers or ask the clerk directly.
