I. CONCEPT OF SALES Art. 1458. By the Contract of sale one of the contracting parties obligates himself to transfer the ownership of and to deliver a determinate thing, and the other to pay therefor a price certain in money or its equivalent. 1. 2. 3. A contract of sale may be absolute or conditional. Essential Characteristics of the Contract of Sale a) Consensual – perfected by mere consent b) Bilateral Reciprocal – both parties are bound by obligations dependent upon each other c) Onerous – because to acquire rights, valuable consideration must be given d) Commutative – as a rule the values exchanged are almost equivalent to each other e) Principal – there is no necessity for it to depend upon the existence of another valid contract f) Nominate – the Code refers to it by a special designation or name, i.e., the Contract of Sale Elements of a Contract of Sale a) Consent or Meeting of the Minds – consent to transfer ownership in exchange for the price b) Determinate Subject Matter – Generally, there is no sale of generic thing; moreover, if the parties differ as to the subject, there can be no meeting of the minds c) Price certain in money or its equivalent – cause or consideration. The price need not be in money Some Principles A CoS without any consideration and executed by a person who is of low intelligence, illiterate, and who could not sign his name or affix his thumbmark, is void. A receipt which merely acknowledges the sum of 1k without any agreement as to the total purchase price lacks the requisites of a valid contract of sale, and is neither valid nor enforceable Natural Elements of a CoS those which are inherent in the Contract, and which in the absence of any contrary provision, are deemed to exist in the Contract) a) b) 4. 5. 1. Accidental Elements Those which may be present or absent in the stipulation, such as the place or time of payment, or the presence of conditions Stages in the Contract of Sale a) Generation or Negotiation b) Perfection – meeting of the minds c) Consummation – when the object delivered and the price is paid Contract of Sale vs Contract to Sell CONTRACT OF SALE The non-payment of price is a resolutory condition. It may by such occurrence put an end to a transaction that once upon a time existed 2. Title over the property passes to the buyer upon delivery 3. Delivery has been made, the seller has lost ownership and cannot recover it unless the contract is resolved or rescinded Warranty Against Eviction – deprivation of the property brought Warranty Against Hidden Defects Sale vs Dation in Payment SALE DATION IN PAYMENT No pre-existing credit 1. there is a pre-existing Gives rise to an credit obligation 2. extinguishes the The cause or obligation consideration is the 3. the cause or price from the consideration here, viewpoint of the seller; from the viewpoint of or the obtaining of the the person offering object from the dation in payment, is viewpoint of the buyer the extinguishing of his debt; from the viewpoint of the creditor, it is the acquisition of the object offered in lieu of the original credit There is agreater 4. there is less freedom freedom in the in the determination of determination of the the price price The giving of the price 5. the giving of the object may generally end the in lieu of the credit obligation of the buyer may extinguish completely or partially the credit, depending on the agreement CONTRACT TO SELL 1. The payment in full of the price is a positive suspensive condition. Hence, if the price is not paid, it is as if the obligation of the seller to deliver and to transfer ownership never became effective and binding 2. Ownership is retained by the seller, regardless of delivery and is not to pass until full payment of the price 3. Since the seller retains ownership, despite delivery, he is enforcing and not rescinding the contract if he seels to oust the buyer for failure to pay Art. 1459. The thing must be licit and the vendor must have a right to transfer the ownership thereof at the time it is delivered is Licit Object – means lawful i.e., within the commerce of men Things may be illicit per se (of its nature) and per accidens (made illegal by provision of law) If the object of the sale is illicit, the contract is null and void The right of redemption and usufruct may be sold, so also may literary, artistic and scientific works. There may be a contract of sale of goods, whose acquisition by the seller depends upon a contingency which may or may not happen Art. 1460. A thing is determinate when it is particularly designated or physical segregated from all others of the same class. The requisite that a thing be determinate is satisfied is at the time the contract is entered into, the thing is capable of being made determinate without the necessity of a new or further agreement between the parties. Determinate – specific, but it is not essential really that at the time of perfection, the object be already specific. It is sufficient that it be capable of being determinate without need of any new agreement. Art. 1461. Things having a potential existence may be the object of a contract of sale. The efficacy of the sale of a mere hope or expectancy is deemed subject to the condition that the thing will come into existence. Sale of Goods – may be future or existing goods Future Goods – are those which are still to be manufactured, raised, acquired by the seller after the perfection of the contract or things whose acquisition depends upon a contingency which may or may not happen. Art. 1463. The sole owner of a thing may sell an undivided interest therein. Art. 1564. In the case of fungible goods, there may be a sale of an undivided share of a specific mass, though the seller purports to sell and the buyer to buy a definite number, weight or measure of the goods in the mass, and through the number, weigh or measure of the goods in the mass is undetermnined. By such a sale the buyer becomes owner in common of such a share of the mass as the number, weight or measure bought bears to the number, weight or measure of the mass. If the mass contains less than the number, weight or measure bought, the buyer becomes the owner of the whole mass and the seller is bound to make good the deficiency from goods of the same kind and quality, unless a contrary intent appears. The sale of a vain hope or expectancy is void. Things with Potential Existence 1. All my rice harvest next year 2. Young animals not yet in existence or ungrown fruits 3. A particular wine a vineyard is expected to produce 4. The expected goodwill of a business 5. The wool that shall, thereafter grow upon a sheep Sale of an Expected Thing (Emptio Rei Sperati) If the sale did not materialize, the sale is not effective Deals with a future thing Sale of the Hope Itself (Emptio Spei) It does not matter whether the expected thing materialized or not, what is important is that the hope itself validly existed Deals with a present thing Ex: sale of a valid sweepstakes ticket Vain Hope or Expectancy If the hope or expectancy itself is vain, the sale itself is void Be noted that this is not an aleatory contract for while in an aleatory contract there is an element of chance, here, there is completely no chance Ex: sale of a losing ticket for a sweepstakes already run Art. 1462. The goods which form the subject of a contract of sale may be either existing goods, owned or possessed by the seller, or goods to be manufactured, raised or acquired by the seller agter the perfection of the contract of sale, in this Title called “future goods.” Art. 1465. Things subject to a resolutory condition may be the object of a contract of sale. Examples 1. Property subject to reserve troncal may be sold 2. A usufruct that may end when the naked owner becomes a lawyer may be sold Art. 1466. In constrying a contract containing provisions characteristic of both the contract of sale and of the contract of agency to sell, the essential clauses of the whole instrument shall be considered. Contract to Sell vs Contract of Agency to Sell Contract to Sell Contract of Agency to Sell 1. Buyer pays the price 1. 2. Buyer after delivery becomes the owner 2. 3. Seller warrants 3. Agent delivers the price which in turn he got from his buyer The agent who is supposed to sell does not become the owner, even if the property has already nee delivered to him Agent who sells assumes no personal liability as long as he acts within his authority and in the name of the principal Art. 1467. A contract for the delivery at a certain price of an article which the vendor in the ordinary course of his business manufactures or procures for the general market, whether the same is on hand at the time or not, is a contract of sale, but if he goods are to be manufactured specially for the customer and upon his special order, and not for the general market, it is a contract for a piece of work. Rule to determine if the Contract is One of Sale or a Piece of Work 1. If ordered in the ordinary course of business – SALE 2. If manufactured specially and not for the markert -- PIECE OF WORK Schools of Thought 1. Massachusetts Rule – if specially done at the order of another, this is a contract for a PIECE OF WORK. Philippines follows this rule 2. New York Rule – If the thing already exists, it is a SALE, if not, WORK 3. English Rule – If material is more valuable, SALE; if skill is more valuable, WORK If I ask someone to construct a house for me, is this a contract of sale or for a piece of work? If he will construct on his own land, and I will get both the land and the house it would seem that this can be very well treated as a SALE ______________________________________________ Art. 1468. If the consideration of the contract consists partly in money, and partly in another thing, the transaction shall be characterized by the manifest intention of the parties. If such intention does not clearly appear, it shall be considered a barter if the value of the thing given as a part of the consideration exceeds the amount of the money or its equivalent; otherwise it is a sale Rules to Determine whether Contract is one of Sale or Barter 1. Intent 2. If intent does not clearly appear a) If the thing is more valuable than money – BARTER b) IF 50-50 – SALE c) If the thing is less valuable than money – SALE In order to judge the intention, we must consider the contemporaneous and consequent acts of the parties. Art. 1469. In order that the price may be considered certain, it shall be sufficient that it be so with reference to another thing certain, or that the determination thereof be left to the judgment of a specified person or persons. Should such person or persons be unable or unwilling to fix it, the contract shall be inefficacious, unless the parties subsequently agree upon the price. If the third person or persons acted in bad faith or by mistake, the courts may fix the price. Where such third person or persons are prevented from fixing the price or terms by default of the seller or the buyer, the party not in fault may have such remedies against the party in fault as are allowed the seller or the buyer, as the case may be When no specific amount is stipulated If there is no specific amount that has been agreed upon, the price is still considered CERTAIN: a) If it be certain with reference to another thing certain (ex: price of tuition fee charged at Ateneo for a pre-bar review course) b) If the determination of the price is left to the judgment of a specified person or persons c) In the cases provided under Art. 172 of the Civil Code Art. 1470. Gross inadequacy of price does not affect a contract of sale, except as it may indicate a defect in the consent, or that the parties really intended a donation or some other act or contract In ORDINARY SALE, the sale remains valid even if the price is very low. If there was vitiated consent, the contract may be annulled but only due to such vitiated consent In EXECUTION OF JUDICIAL SALES, mere inadequacy of price will not set aside a judicial sale of a property; but if the price is so inadequate as to shock the conscience of the court, it will be set aside Art. 1471. If the price is simulated, the sale is void, but the act may be shown to have been in reality a donation, or some other act or contract. Simulated Price The price must not be fictitious. Therefore, isf it is, the contract as a sale is void It may however, be valid as a donation or some other agreement, provided the requirements of donations or other agreements have been complied with. If the requirements do not exists, the contract as a sale is absolutely void A price is simulated IF It is fictitious There being no price, there is no cause or consideration; hence the contract is void as a sale A rescission of the price will not invalidate a sale Fictitious Sale A mother sells to her child a property at a very low much lower price than what she has paid for it ______________________________________________ Art. 1472. The price of securities, grain, liquids, and other things shall also be considered certain, when the price fixed is that which the thing sold would have on a definite day, or in a particular exchange or market, or when an amount is fixe above or below the price on such day, or in such exchange or market, provided said amount be certain. Certainty of Price of Securities I can sell to you today a Mont Blanc fountain pen at the price equivalent to the stock quotation two days from today of 100 shares of PLDT If stock market price cannot be ascertained if the stock quotation price two days later cannot really be ascertained at that time, the sale is inefficacious Art. 1473. The fixing of the price can never be left to the discretion of one of the contracting parties. However, if the price fixed by one of the parties is accepted by the other, the sale is perfected. Price cannot be left to the discretion of one party REASON: The other could not have consented to the price, for he did not know what it was Art. 1474. Where the price cannot be determined in accordance with the preceding articles, or in any other manner, the contract is inefficacious. However, if the thing or any part thereof has been delivered to and appropriated by the buyer, he must pay a reasonable price therefore. What is a reasonable price is a question of fact dependent on the circumstances of each particular case. Effect if the price cannot be determined 1. The sale is void for the buyer cannot fulfil his duty to pay 2. If the buyer has made use of it, he should not be allowed to enrich himself unjustly at another’s expense. So, he must pay a reasonable price. The seller’s price,however, must be the one paid if the buyer knew how much the seller was charging and there was an acceptance of the goods delivered. Here, there is an implied assent to the price fixed, Art. 1475. The contact of sale is perfected at the moment there is a meeting of the minds upon the thing which is the object of the contract and upon the price. From that moment, the parties may reciprocally demand performance, subject to the provisions of the law governing the form of contracts Nature of Contract Consensual: perfected by mere consent Delivery or payment is not essential for perfection The contract of sale is consummated upon delivery and payment Requirements for Perfection 1. When the parents are face to face when an offer is accepted without conditions and without qualifications 2. When contract is through correspondence or through a telegram, there is perfection when the offeror receives or has knowledge of the acceptance by the offeree o If the buyer has already accepted, but the seller does not know yet of the acceptance, the seller may still withdraw 3. when the sale is made subject to a suspensive condition, perfection is from the moment the condition is fulfilled Before perfection No mutual rights and obligations exist between the would be buyer and the would be seller Accepted Bilateral Promise to Buy and Sell In sense, is similar to, but not exactly the same as, as perfected contract of sale Permitted under Art. 1479, par 1 “A promise to buy and sell a determinate thing for a price certain is reciprocally demandable” Formalities for Perfection Under the Statute of Frauds, the sale of 1. Real Property – regardless of the amount, must be in writing 2. Personal Property, if P500 or more must be in writing to be enforceable. If it is orally made, it cannot be enforced by a judicial action except if the defense of the Statute of Frauds is waived Perfection in the Case of Advertisements Advertisements are mere invitations to make an offer, and therefore, one cannot compel adviser to sell Transfer of Ownership Mere perfection of a contract does not transfer ownership. Ownership of the object is transferred only after delivery Effect of Perfection The mutual parties must now comply with their mutual obligations Art. 1476. In the case of a sale by auction: 1) Where goods are put up for sale by auction in lots, each lot is the subject of a separate contract of sale 2) A sale by auction is perfected when the auctioneer announces its perfection by the fall of the hammer, or in any other customary manner. Until such announcement is made, any bidder may retract his bid; and the auctioneer may withdraw the goods from the sale unless the auction has been announced to be without reserve 3) A right to bid may be reserved expressly by on behalf of the seller, unless otherwise provided by la or by stipulation 4) Where notice has not been given that a sale by auction is subject to a right to bid on behalf of the seller, it shall not be lawful for the seller to bid himself or to employ or induce any person to bid at such sale on his behalf or for the auctioneer, to employ or to induce any person to bid at such sale on behalf of the seller or knowingly to take any bid from the seller of any person employed by him. Any sale contravening this rule may be treated as fraudulent by the buyer When sale by Auction is perfected The sale is perfected when the auctioneer announces its perfection by the fall of the hammer or in other customary manner Before the fall of the Hammer: 1. a bidder may: retract his bid because every bidding is merely an offer and therefore, before it is accepted, it may be withdrawn. The assent is signified on the part of the seller by knocking down the hammer. An auctioneer may withdraw the goods from the sale unless the action has been announced to be without reserved. It is because the bid is merely an offer, not an acceptance of an offer to sell. Therefore, it can be rejected. What the auctioneer does in withdrawing is merely reject the offer When Seller Can Bid? 1. A right to bid was reserved; and 2. Notice was given that the sale by auction is subject to a right to bid on behalf of the seller May a seller employ others to bid for him? Yes, provided that he has notified the public that the auction is subject to the right to bid on behalf of the seller People who bid for the sellers, but are not themselves bond are called by bidders or puffers BUT, without the notice, any sale contravening the rule may be treated by the buyer as fraudulent 2. Art. 1477. The ownership of the thing sold shall be transferred to the vendee upon the actual or constructive delivery thereof. When ownership is transferred Perfection by delivery Kinds of Delivery 1. Actual 2. Constructive – including any other manner signifying an agreement that the possession is transferred Art. 1478. The parties may stipulate that ownership in the thing shall not pass to the purchaser until he has fully paid the price When ownership is not transferred despite delivery Generally, ownership is transferred upon delivery, but even if delivered, the ownership may still be with the seller till full payment of the price is made, IF there is a stipulation to this effect The stipulation is usually knows as pactum reservati dominie and is common in sales on instalment plans Art. 1479. A promise to buy and sell a determinate thing for a price certain is reciprocally demandable An accepted unilateral promise to buy or to sell a determinate thing for a price certain is binding upon the promissor if the promise is supported by a consideration distinct from the price. First Paragraph – MUTUAL PROMISE A promises to buy something and B promises to sell it at an agreed price. This is a promise to buy and sell, clearly a bilateral reciprocal contract Second Paragraph – ACCEPTED UNILATERAL PROMISE Only one makes a promise. This promise is accepted by the other A promises to sell to B. B accepts the promise, but does not in turn promise to buy. This is an accepted unilateral promise to sell. It is binding on the promissor only if the promise is supported by a consideration distinct from the price. Policitation – unilateral promise to buy or to sell which is not accepted. This produces no juridical effect, and creates no legal bond. This is a mere offer, and has not yet been conversed into a contract. Bilateral Promise – a bilateral promise to buy and sell a certain thing for a price certain gives to the contracting parties personal rights in that each has the right to demand from the other the fulfilment of the obligation. Unilateral Promise – the acceptance of a unilateral promise to sell must be plain, clear and unconditional. Therefore, if there is a qualified acceptance with the terms different from the offer, there is no acceptance, that is, there is no promise to buy and there is no perfected sale Option A contract granting a person the privilege to buy or not to buy certain objects at any time within the agreed period at a fixed price Separate and distinct contract fron the contract which the parties may enter into upon the consummation of the contract An option must have its own cause or consideration If an option is granted, how long is the offer bound by his promise? If no period has been stipulated, the court will fix them Is the right to buy, a right that may be transmitted to others? YES, unless it was granted for purely personal considerations Art. 1480. Any injury to or benefit from the thing sold, after the contract has been perfected, from the moment of the perfection of the contract to the time of delivery, shall be governed by Articles 1163 to 1166 and 1262. This rule shall apply to the sale of fungible things, made independently and for a single price, or without consideration of their weight, number or measure. Should fungible things be sold for a price fixed according to weight, number, or measure, the risk shall not be imputed to the vendee until they have been weighed, counted or measured, and delivered, unless the latter has incurred in delay. Who bears the risk of loss? 1. If the object was lost before perfection The seller bears the loss because there was no contract, for there are no cause or consideration. Being the owner, the seller bears the loss, therefore, he cannot demand payment of the price 2. If the object was lost after delivery to the buyer The buyer bears the risk of loss (Res perit domino) 3. If the object was lost after perfection but before delivery The buyer bears the loss, as exception to the rules of res perit domino REASONS: i. had the sale been perfected, the buyer would have borne the loss, that is, he would still have to pay for the object even if no delivery had been made ii. Under Art. 1262, an obligation which consists in the delivery of a determinate thing shall be extinguished if it should be lost or destroyed without the fault of the debtor, and before he has incurred in delay iii. Art. 1583 says that in case of loss, deterioration or improvement of the thing before its delivery, the rule in Art. 1189 shall be observed, the vendor being considered the debtor. Art. 1189 in turn, says, if the thing is lost without the fault of the debtor, the obligation shall be extinguished iv. Art. 1269 on loss states that: the obligation having been extinguished by the loss of the thing, the creditor shall have all the rights of action which the debtor may have against third persons by reason of the loss v. Historically, the buyer has always borne the loss vi. Since the buyer gets the benefits during the intervening period, it is clear that he must also shoulder the loss Exceptions: a) If the object sold consists of fungibles sold for a price fixed according to weight, number or measure b) If the seller is guily of fraud, negligence, default o violation of contractual term c) When the object sold is generic because genus does not perish Fungibles – are personal property which may be replaced with equivalent things Art. 1480. In the contract of goods by description or by sample, the contract may be rescinded if the bulk of the goods delivered do not correspond with the description or sample, and if the contact be by sample as well as by description, it is not sufficient that the bulk of goods correspond with the sample if they do not also correspond with the description. Art. 1482. Whenever earnest money is given in a contract of sale, it shall be considered as part of the price and a proof of the perfection of the contact. Sale by Description – where the seller sells things as being of a certain kind, the buyer merely relying on the seller’s representations, or descriptions. Generally, the buyer has not previously seen the goods, or even if he has seen them, he believes that the description tallies with the goods he has seen Sale by Sample – where the seller warrants that the bulk of the goods shall correspond with the Earnest Money – also called “arras”, is something of value to show that the buyer was really in earnest, and given to the seller to bind the bargain. IT APPLIES TO A PERFECTED SALE. Significance of EM: 1. Considered part of the purchase price 2. Proof of the perfection of a contract Art. 1483. Subject to the provisions of the Statute of Frauds and of any other applicable stature, a contract of sale may be made in writing, or by word of mouth, or partly in writing and partly by word of mouth, or may be inferred from the conduct of the parties. Effect if Notary Public is not authorized If the Deed of Sale of land is notarized by a notary public whose authority had expired, the sale would still be valid, since for validity of the sale, a public instrument is not even essential (Sorfano vs Latono) Art. 1484. In a contract of sale of personal property the price of which is payable in instalments,, the vendor may exercise any of the following remendies: 1. 2. 3. The buyer shall have a reasonable opportunity of comparing the bulk with the description or the sample. sample in kind, quality and character. Only the sample is exhibited. The bulk is not present, and so there is no opportunity to examine or inspect it. Remedies of a Buyer if the bulk of goods purchases does is defective or damaged a. To return the thing, and recover the money paid; OR b. To retain the thing, and still sue for breach of warranty Sale by Description and Sample – the mere exhibition of the sample does not necessarily make it a sale by sample. This exhibition must have been the sole basis or inducement of the sale. A sale by sample may still be had even if the sample was shown only in connection with a sale to the first purchaser. There can be sale by sample even if the sale is “as is” Exact fulfilment of the obligation, should vendee fail to pay Cancel the sale, should the vendee’s failure to pay or cover 2 or more instalments Foreclose the chattel mortgage on the thing sold, if one has been constituted, should the vendee’s failure to pay cover 2 or more instalments. In this case, he shall have no further action against the purchaser to recover any unpaid balance of the price. Any agreement to the contrary shall be void. Requisites before Art. 1484 may be applied 1. There must be a contract 2. The contract must be one of sale 3. What is sold is personal property 4. The sale must be on the instalment plan The remedies in this article are alternative, and if one is exercised, the others cannot be made use of. Instances when Art. 1484 does not apply 1. Real Estate Mortgage 2. Sale of real property on straight terms Art. 1485. The preceding article shall be applied to contracts purporting to be leases of personal property with option to buy, when the lessor has deprived the lessee of the possession of the possession or enjoyment of the thing. “When the lessor has deprived the lessee of the possession or enjoyment of the thing” This means that for failure to pay, the lessor is apparently exercising the right of an unpaid seller, and has taken possession of the property When is Lease construed as Sale Even if the word lease is employed, when a sale on instalment is evidently intended, it must be construed as a sale 3. 4. II. III. IV. V. VI. VII. VIII. IX. Art. 1486. In the cases referred to in the two preceding articles, a stipulation that the instalments or rents paid shall not be returned to the vendee or lessee shall be valid insofar as the same may not be unconscionable under the circumstances. Non-return of instalments paid General Rule: It is required that a case of rescission or cancellation of the sale requires mutual restitution, that is, all partial payment of price or rents must be returned Exception: It is valid to stipulate that there should be no returning of the price that has been partially paid or of the rents given, provided the stipulation is not unconscionable (See Maceda Law) Art. 1487. The expenses for the execution and registration of the sale shall be borne by the vendor, unless there is a stipulation to the contrary. Art. 1488. The expropriation of property for public use is governed by special laws 1. 2. Nature of Expropriation – it is involuntary in nature, that is, the owner may be compelled to surrender the property after all the essential requisites have been complied with. Therefore, generally, it does not result in a sale. There is no exception to this rule When Transaction is one of Sale – If the property owner voluntarily sells the property to the government, this would be a sale, and not an appropriation Eminent Domain vs Expropriation Eminent Domain refers to the right give to the state, whereas Expropriation usually refers to the process Essential Requisites for Expropriation Taking by competent authority Observance of due process of law X. XI. XII. XIII. XIV. XV. XVI. XVII. XVIII. XIX. XX. XXI. XXII. XXIII. Taking for public use Payment of just compensation Just Compensation: is the market value plus consequential damages, if any, minus the consequential benefits, if any. BUT, the benefits may be set off only against the consequential damages, and not against the basis value of the property taken.
