name change process in India (Central Gazette) for Overseas Citizen of India

Dear Sir, I am Abilash K, a holder of an Indian overseas citizen from Goa. I changed my name while becomes a British citizen. In India, I haven't changed my name, so I'd like to use my new name. So could you tell us how we should proceed with that name change in India? It is true that the Central Gazette can only be officially notified for "INDIAN CITIZENS". A person who obtained foreign citizenship by renouncing Indian citizenship cannot change his or her name in India even if he or she is an OCI holder? What about property papers under the old name? How can we sell it when we change our name abroad? I've heard that any Indian law that says the OCI doesn't have to change their name in India and not to publish in the central Gazette. Thank you for your time and looking forward to your response Abilash K
