DEO stands for Defence Estate Organization, which is responsible for managing and administering defence land and properties in India. The DEO maintains a record of all defence properties and their ownership details. This information is used to ensure proper management and utilisation of the properties.
In the context of a property dispute, the DEO register can be used as evidence of ownership. If the register still shows your uncle’s name as the owner of the property, it may indicate that the sale of the property was not valid or legal.
You have breached the terms and conditions upon which the bungalow was given to your uncle. In this scenario the DEO has accrued the right to evict the inmates of that bungalow and also initiate legal proceedings for the cancellation of sale deed.
