Certain sites in Agra were granted by the Mughals to their  Royal Assistants if their request (Urz) for land was considered genuine (Wazib). Initialy such sites were under the control of the Collector. However, after establishment of the Cantonment such sites were transferred to the Cantonment Authority. They are now under the management of the Defence Estates Officer (DEO). Niether the structures standing on such sites can be extended nor agricultural  sites be used for other purposes without the sanction of competent authority under the terms and conditions of the grant. There are 09 building sites and  13 agricultural sites under these terms.
