A comprehensive legislative act passed at Tynwald Court on 4 February 1703 by James, Earl of Derby, establishing customary tenures, inheritance rules, fines, rents, and services for Isle of Man tenants. Ratified by Derby's confirmation in 1704, it also includes supplementary acts addressing carriages, mortgages/alienations, intacks/cottages, and quarry rights. This is foundational documentation for understanding pre-Revestment Manx property law and lord-tenant relations.
