Manor (from the Latin manerium)
The principal manorial court was the Court Baron which [dealt] " ... largely with internal matters on the estate, including infringements of the lord's rights and prerogatives, agrarian disputes between tenants and changes of tenancy. At the heart of the court baron's work lay the customs of the manor, which varied from manor to manor and governed the details of how tenants held their land (hence the term 'customary tenure').
