The 1703 Act of Settlement, passed at Tynwald Court, formally codified and confirmed the estates, tenures, fines, rents, suits, and services owed by tenants to James, Earl of Derby, Lord of the Isle of Man. The Act resolved long-standing disputes between the Lords and tenants, established hereditary customary estates, fixed fine schedules for inheritance and alienation, and set terms for mortgages, cottages, intacks, and quarries. It is fundamental to understanding Manx land law and property rights on the eve of the 18th century.
