The Deed of Absolute Sale (DOAS) completes the sale of a real estate property. Once executed, this legally transfers the property and its rights from the seller to the buyer. The deed also serves a a proof that the transfer occurred. The Deed of Absolute Sale should also have no stipulated conditions attached other than the buyer's payment.

When buying a property, a notarized DOAS is among the required documents by the Bureau of Internal Revenue (BIR) in order to transfer the property title documents from the name of the seller to the buyer. It is worth noting that once a home loan application is approved, the bank will ask for the transferred title before the loan proceeds can be released.
