🏢 Wilmington City Hall
Wilmington's own city government keeps its local records: council or board meeting minutes, local ordinances and resolutions, local permits and licenses, and its own budget and contracts. Requests for those records go to the city clerk under the Delaware Freedom of Information Act. Birth and death certificates, marriage records, deeds and court files are generally kept by county and state offices rather than by the city; see the offices below.
