The documents required to sell a residential property are the housing society share certificate and the sale/purchase deed. Sale deed will confirm if the land is in the name of the seller and only he/she has the full right to sell the land. You need a copy of previous deeds, if required, to confirm the authenticity of the deal and the property. You also need original copies of stamp duty and registered house documents. The seller will also require an NOC from the Housing society. In case of a joint ownership, the owner/owners have to submit documented consent. Home-buyers insist on all these documents if they are opting for a Housing loan.
