The Family Search website has established a searchable database of all estate files from North Carolina counties. Here is the description:
North Carolina Estate Files, 1663-1979
Index and images of estate files from North Carolina counties. The originals were filmed at the North Carolina Department of Archives and History. The estate records contain loose papers relating to the settlement of estates including such matters as provision for heirs including minor children as well as distribution of funds, land and property, including slaves. This project was indexed in partnership with the North Carolina Genealogical Society and Library.
