The Inventory of the County Archives of Delaware: No. 1, New Castle County, by the Delaware Historical Records Survey is another collection. The Court Records of Kent County, Delaware, 1680-1705 and Sussex County Court Records 1677-1710 also contain compilations of early court records. Many other early court records for indentures, naturalizations, criminal cases and civil cases can be found at the Delaware Public Archives, but New York, Maryland and Pennsylvania also hold many records for what is now present-day Delaware.

The superior court and court of common please handled criminal and civil court cases. The chancery court handled trust, estate and equity cases. Divorces were handled by the county prothonotary, along with naturalizations, criminal court records and civil court records, until 1975. Many of those records are now held at the Delaware Public Archives. The recorder of deeds holds the land records, while the Orphans’ Court and register of wills handle estate matters. The court of chancery and the Orphans’ Court were merged in 1975 and those records are held with each county’s register of chancery. See Also Research In Court Records.

Mortgages and deeds are kept separately in each of Delaware’s counties and the recorder of deeds holds all major land records. Any documents pertaining to mortgages, appointments or land are the responsibility of the County Register of Deeds Office. However, the Delaware Public Archives now has control of many of those older records. See Also Guide to U.S. Land Records Research
