The elements of contracts under the general provisions of the Civil Code are foundational to determining the existence, validity, and binding force of agreements. A precise understanding of these elements enables Bar examinees to resolve essay questions involving negotiations, defective agreements, or disputes over enforceability by systematically analyzing whether a contract was perfected and what legal consequences follow from any defect.

Core Legal Basis and Definition

Article 1305 of the Civil Code defines a contract as “a meeting of minds between two persons whereby one binds himself, with respect to the other, to give something or to render some service.”

Contracts are governed by the principles of autonomy of will (Article 1306), relativity (Article 1311), consensuality (Article 1315), and obligatory force between the parties.

The elements of every contract are classified into three categories under established civil law doctrine:

Essential elements — without which there is no contract at all.
Natural elements — presumed by law or custom to exist in the contract unless the parties stipulate otherwise.
Accidental elements — exist only if the parties expressly stipulate them.

Essential Requisites / Elements / Components

Article 1318 of the Civil Code provides: “There is no contract unless the following requisites concur: (1) Consent of the contracting parties; (2) Object certain which is the subject matter of the contract; (3) Cause of the obligation which is established.”

These three essential elements must concur for a contract to be perfected. The absence of any one renders the contract inexistent and void ab initio — it produces no legal effect, cannot be ratified, and may be attacked collaterally.

Consent

Consent is manifested by the meeting of the offer and the acceptance upon the thing and the cause which are to constitute the contract (Article 1319).

Requisites:

The offer must be certain and serious.
Acceptance must be absolute and unconditional. A qualified acceptance constitutes a counter-offer that rejects the original offer.
Consent must be free, intelligent, and spontaneous.

Capacity to give consent (Articles 1327–1329): Parties must be of legal age and not otherwise incapacitated. The following cannot give consent:

Unemancipated minors;
Insane or demented persons;
Deaf-mutes who do not know how to write.

Contracts entered into by incapacitated persons are voidable (Article 1390), not inexistent.

Vices of consent that render the contract voidable (Article 1330):

Mistake — substantial error on the object or principal conditions of the contract (Arts. 1331–1333); error in value or motives generally does not vitiate consent.
Violence or intimidation — must be serious and sufficient to overcome the will of the contracting party (Arts. 1335–1336).
Undue influence — improper advantage taken of a position of power or confidence (Art. 1337).
Fraud (dolo) — serious misrepresentation or concealment without which the other party would not have consented (dolo causante). Incidental fraud (dolo incidente) gives rise only to an action for damages (Arts. 1338–1344).

Object

The object must be certain, licit, and possible.

Key codal rules:

Article 1347: All things not outside the commerce of men (including future things, if possible) and all rights not intransmissible may be the object of a contract. Contracts upon future inheritance are prohibited except in cases expressly authorized by law.
Article 1348: Impossible things or services cannot be the object of contracts.
Article 1349: The object must be determinate as to its kind. Indeterminate quantity is allowed if it can be determined without the need for a new contract.

The object must not be contrary to law, morals, good customs, public order, or public policy.

Cause

Cause is the essential or immediate reason that moves the parties to enter into the contract.

Article 1350:

In onerous contracts — the prestation or promise of a thing or service by the other party.
In remuneratory contracts — the service or benefit which is remunerated.
In contracts of pure beneficence — the mere liberality of the benefactor.

Article 1351: Particular motives of the parties are different from the cause.

Article 1352: Contracts without cause, or with unlawful cause, produce no effect whatsoever. The cause is unlawful if contrary to law, morals, good customs, public order, or public policy.

Article 1353: The statement of a false cause renders the contract void, unless it is proved that the contract was founded upon another cause which is true and lawful.

Important distinction: Cause is the objective, essential reason for the obligation. Motive is the personal or subjective reason of a party. A false motive does not ordinarily affect validity unless it is illicit and constitutes the true cause of the contract.

Landmark Supreme Court Doctrines

The Supreme Court has consistently held that the three essential requisites under Article 1318 are indispensable:

In Montecillo v. Reynes (G.R. No. 138018, July 26, 2002), the Court ruled that a purported contract lacking cause — one of the three essential requisites — is not a valid contract and produces no effect whatsoever.
Perfection of consensual contracts occurs upon the concurrence of the essential elements, i.e., when there is a meeting of minds manifested by the offer and absolute acceptance upon the thing and the cause (reiterated in decisions applying Articles 1318 and 1319, including Swedish Match, AB v. Court of Appeals, G.R. No. 128120, October 20, 2004).
Absence of any essential element results in an inexistent contract, which is void from the beginning, produces no legal effect, cannot be ratified, and may be collaterally attacked by any interested party.
Form is not an essential element for the validity of most contracts. Contracts are obligatory in whatever form they may be entered into, provided the essential requisites are present (Article 1356). Special forms are required only for validity in solemn contracts or for enforceability under the Statute of Frauds (Article 1403).

Key Exceptions, Qualifications, and Distinctions

Inexistent/Void vs. Voidable: Missing essential element or illicit cause/object → inexistent/void (no effect, no ratification, imprescriptible defense). Vitiated consent or incapacity of only one party → voidable (annullable at the instance of the injured party within the prescriptive period under Art. 1391).
Consensual vs. Real Contracts: Consensual contracts are perfected by mere consent. Real contracts (deposit, pledge, commodatum) require delivery of the object for perfection (Article 1316).
Formal/Solemn Contracts: Require a special form for validity (e.g., donation of immovable property must be in a public instrument, Art. 749).
Absolute vs. Relative Simulation: Absolute simulation (no real intent to be bound) → inexistent contract. Relative simulation (parties conceal their true agreement) → the hidden contract is valid if its own essential elements are present.
Future Things: Permissible as object if possible and not future inheritance (prohibited except as expressly authorized by law).
Dolo Causante vs. Dolo Incidente: Only the former vitiates consent and renders the contract voidable.

How This Topic Appears in Bar Essay Questions

Essay questions typically present facts of negotiations, a written instrument, or an alleged agreement and ask whether a contract was perfected, its status (valid, void, voidable, unenforceable), or the rights and remedies of the parties.

Common fact patterns:

Offer followed by qualified acceptance or revocation before acceptance reaches the offeror.
Agreement on some terms but dispute over meeting of minds on price, object, or cause.
Contract involving a minor, alleged fraud/intimidation/undue influence, or false stated consideration.
Stipulation for an illegal object or cause (e.g., sale of prohibited drugs or contract to stifle prosecution).
Written document that appears incomplete or lacks clear agreement on all essential elements.

Examiner expectations:

Element-by-element analysis using the exact language of Articles 1318, 1319, 1347–1349, and 1350–1353.
Clear conclusion on the status of the contract and its legal effects (nullity, annulment, damages, restitution under Arts. 1398–1402).
Application of distinctions (cause vs. motive; dolo causante vs. incidente; inexistent vs. voidable).

Common mistakes:

Treating form as an essential element for validity.
Confusing cause with motive or with the object itself.
Failing to distinguish void from voidable contracts and their respective effects and prescriptive periods.
Assuming that partial performance cures absence of an essential element.

Best answer structure:

State the governing rule with codal basis (start with Arts. 1305 and 1318).
Define and break down each essential element with its specific requisites.
Apply the facts to each element one by one.
Conclude on the existence/status of the contract and discuss consequences/remedies.

Practical Application Tips or Memory Aids

Mnemonic: COC — Consent, Object, Cause. “No COC, no contract.”

Quick Comparison Table:

Category	Essential	Natural	Accidental
When they exist	Always required for any contract	By law or custom (presumed)	Only if expressly stipulated
Examples	Consent, Object, Cause	Consequences in keeping with good faith, usage & law (Art. 1315); implied warranties in nominate contracts	Conditions, terms/periods, modes, penal clauses, arbitration agreements
Effect if missing	No contract (inexistent/void)	May be validly excluded by agreement	Simply not included in the contract
Source	Articles 1318–1353	Law, custom, nature of the contract	Agreement of the parties

Drafting/Answer Tip: In any essay involving a written instrument, verify whether the document shows clear agreement on all three essential elements with sufficient certainty. If not, argue that no contract was perfected.

Key Takeaways

Article 1318 is the single most important provision: Consent + Object certain + Cause = perfected contract. Master the specific rules for each element.
Absence of any essential element produces an inexistent contract — void ab initio, no ratification possible, collateral attack allowed.
Vitiated consent or incapacity of one party produces a voidable contract — annullable within four years from discovery or cessation of the vice/incapacity.
Form is not an essential element for validity in most contracts (Article 1356); it matters for enforceability (Statute of Frauds) or validity in solemn contracts.
Always distinguish cause (objective, essential) from motive (personal); false cause voids the contract unless another true and lawful cause is proved (Article 1353).
High-yield distinctions for essays: dolo causante vs. dolo incidente; absolute vs. relative simulation; real vs. consensual contracts; inexistent/void vs. voidable.
In every essay answer, analyze the facts element by element before concluding on the status and effects of the contract.
