Quick answer

The distinction between a contract of sale and a contract to sell is one of the most consequential in property transactions, especially in the purchase of real estate on installment. In a contract of sale (an absolute sale), the seller agrees to transfer, and does transfer, ownership of the thing to the buyer upon the perfection of the contract and the delivery of the thing; ownership passes to the buyer upon delivery, even if the price has not been fully paid. Non-payment of the price in an absolute sale is a resolutory condition, that is, a ground for the seller to rescind or cancel the sale (subject to the rules on rescission and, for real property in installments, the Maceda Law), but ownership has already passed and the seller must go through rescission to recover it. In a contract to sell, by contrast, the seller expressly reserves ownership and does not transfer it to the buyer despite delivery, until the buyer has fully paid the purchase price; full payment is a positive suspensive condition, the happening of which is required before the seller is obliged to transfer ownership. This means that in a contract to sell, if the buyer fails to pay the full price, the seller does not need to rescind, because the obligation to sell (to transfer ownership) never arose; the non-fulfillment of the suspensive condition (full payment) simply prevents the transfer, and the contract is not a sale that must be undone but a promise whose condition failed. The practical consequences are significant: in a contract of sale, the buyer becomes the owner on delivery and a later sale to a third person would be a double sale governed by Article 1544; in a contract to sell, since ownership stayed with the seller, a sale to another buyer after the first buyer's default is generally not a double sale of the same right. The label used by the parties is not conclusive; the courts look at the true intent, particularly whether ownership was reserved until full payment. So the crucial difference is that a contract of sale transfers ownership upon delivery, while a contract to sell withholds ownership until the price is fully paid.

The Crucial Difference: When Ownership Passes

In a contract of sale, ownership passes to the buyer upon delivery, even if the price is unpaid. In a contract to sell, the seller reserves ownership until the price is fully paid.

Effect of Non-Payment

In a sale, non-payment is a resolutory condition — the seller must rescind to recover (subject to the Maceda Law for realty installments). In a contract to sell, full payment is a suspensive condition; if unpaid, the obligation to transfer ownership never arose, so no rescission is needed.

Why It Matters

In a sale, the buyer owns on delivery, and a later sale is a double sale (Art. 1544). In a contract to sell, ownership stayed with the seller, so a sale to another after default is generally not a double sale. The label is not conclusive — courts look at whether ownership was reserved.

Frequently Asked Questions

What is the difference between a contract of sale and a contract to sell? In a contract of sale, ownership passes to the buyer upon delivery even if the price is unpaid. In a contract to sell, the seller reserves ownership and does not transfer it until the buyer has fully paid the price.

What happens if the buyer does not pay in a contract to sell? The obligation to transfer ownership never arises, because full payment is a positive suspensive condition. The seller does not need to rescind; the non-fulfillment of the condition simply prevents the transfer of ownership.

What happens if the buyer does not pay in a contract of sale? Ownership has already passed on delivery, so non-payment is a resolutory condition. The seller must go through rescission to recover the property, subject to the rules on rescission and the Maceda Law for real property sold on installment.

Is the label the parties use conclusive? No. The courts look at the true intent of the parties, particularly whether ownership was reserved until full payment, rather than merely the label used, in determining whether it is a contract of sale or a contract to sell.
