A sale deed is a crucial legal document that transfers property ownership from the seller to the buyer. It is essential for purchasing and registering a property, with the registration based on the details in the deed. This document serves as proof of ownership and must be signed by both parties to be legally binding. Registration at the sub-registrar’s office is mandatory, requiring the presence of both the buyer, seller, and their witnesses, along with the payment of stamp duty and registration fees. The sale is complete only after the deed is registered.
