What is the difference between deed of sale to deed of absolute sale?

There is no substantial difference between DEED OF SALE and DEED OF ABSOLUTE SALE, except the words that constituted it. Because all sales are absolute whether movable or immovable, unless there is a condition provided in a particular contract, hence, it is another contract also called CONTRACT TO SELL. A CONTRACT TO SELL is substantially different from CONTRACT OF SALE, because the CONTRACT OF SALE is the DEED OF SALE or DEED OF ABSOLUTE SALE itself. The rationale of this CONTRACT OF SALE is that the rights of ownership, including all that is incidental with it are transferred absolutely upon the delivery of the thing sold without any condition; while this CONTRACT TO SELL imposes suspensive condition that is by agreement the title is reserve in the seller until the fulfillment of an obligation, thus, it is also called DEED OF CONDITIONAL SALE.

My answer to this query is supported by doctrines of legal authority in the Philippines, no other than the Honorable Supreme Court. In the avalanche of cases decided by the Supreme Court, it consistently declared that; "The distinction between a contract to sell and a contract of sale is quite germane. In a contract of sale, title passes to the vendee upon the delivery of the thing sold; whereas in a contract to sell, by agreement the ownership is reserved in the vendor and is not to pass until the full payment of the price. In a contract of sale, the vendor has lost and cannot recover ownership until and unless the contract is resolved or rescinded; whereas in a contract to sell, title is retained by the vendor until the full payment of the price, such payment being a positive suspensive condition and failure of which is not a breach but an event that prevents the obligation of the vendor to convey title from becoming effective."
