The meaning of a sale deed is a legal and main document, that acts as evidence, that is executed at the time of sale and transfer. When you buy or sell property, the transaction should be carried out and duly signed between and by both the parties i.e., Vendor and Purchaser. And it should be in the presence of at least two Witnesses. When executed, it should be registered under the Registration Act, 1908 within four months by the Sub Registrar. Thus, only with properly executed transactions, a sale can be completed.
