A comprehensive legislative act passed at Tynwald-Court in 1703 by James, Earl of Derby, establishing and confirming the customary tenure system, fines, rents, and services owed by Isle of Man tenants. The act codifies proposals negotiated between the Lord and tenant representatives (including Ewan Christian and John Stephenson) to resolve longstanding disputes over inheritance, alienation, mortgages, and land improvements. Accompanied by explanatory acts on carriages, mortgages, intacks, and quarries. Directly relevant to understanding pre-Revestment Manx constitutional and economic structures.
