Introduction

Contracts occupy a central position in the regulation of civil transactions. They are the means by which parties define their rights and obligations and allocate the responsibilities and risks associated with the contractual relationship. Contracts form the basis of transactions involving sale, lease, construction, agency, partnership, service provision, and other dealings connected with private life and economic activity.

The Saudi Civil Transactions Law regulates the general provisions governing contracts. It specifies how contracts are formed, the rules governing the expression of intent, the requirements relating to their subject matter, their effects on the contracting parties and third parties, the rules for interpretation and performance, and the consequences of invalidity or termination.

The Civil Transactions Law was issued by Royal Decree No. (M/191), dated 29/11/1444 AH. Its provisions also apply to commercial transactions where no specific provision exists, provided that such application is not inconsistent with the nature of the commercial transaction.

What Is a Contract under the Civil Transactions Law?

A contract is formed when an offer is connected with an acceptance for the purpose of producing a legal effect, subject to any special formalities required by statutory provisions for the formation of certain contracts.

A contract is based on the concurrence of two or more intentions aimed at producing a specific legal effect. This effect may consist of creating a new obligation, transferring an existing right, modifying a legal relationship, or terminating it.

In a sale contract, the seller is obliged to transfer and deliver the sold property, while the buyer is obliged to pay the price. In a construction contract, the contractor is obliged to complete the agreed work, while the employer is obliged to pay the agreed consideration. The content of each contract determines the nature of the rights and obligations arising from it.

How Is a Contract Formed?

A contract consists of an offer made by one party and a corresponding acceptance made by the other party. A contract is not formed where the acceptance differs from the offer on a material issue. Instead, the modified acceptance is treated as a new offer requiring approval from the original offeror.

An offer also lapses in the circumstances specified by law, including the expiry of the period set by the offeror for acceptance without acceptance being made. An acceptance issued after the offer has lapsed does not form a contract; rather, it is treated as a new offer.

The contracting parties are not required to be physically present in the same place. A contract may be formed through correspondence, electronic means, or other communication methods, provided that it is possible to verify that their intentions correspond on the essential matters.

Consensual and Formal Contracts

As a general rule, contracts are governed by the principle of consensuality. Agreement between offer and acceptance is sufficient for formation without the need for a specific form.

However, the law may require certain contracts to be made in writing, notarized, registered, or completed through a specified formality. The contracting parties may also agree that the contract will not be formed until it has been reduced to writing, signed, or another specified procedure has been completed.

Writing required for the formation of a contract differs from writing required merely for proof. A contract may be validly formed, yet difficult to prove in the event of a dispute because the agreement was not documented or because the exchanged correspondence was unclear.

Essential Elements of a Contract

The validity of a contract requires legally recognized consent, a lawful subject matter capable of being dealt with, and parties possessing the necessary legal capacity. The contract must also not violate a mandatory statutory provision or public order.

1. Consent

Consent is the concurrence of the parties’ intentions to conclude the contract and agree on its essential elements. This requires identifying the nature of the relationship, the subject of the obligation, the consideration, the duration, and other matters regarded as fundamental according to the type of contract.

Ongoing negotiations or the exchange of proposals are not sufficient to establish a contract unless the parties reach a final agreement whose content can be determined.

2. Subject Matter of the Contract

The subject matter of the contract is the property, act, or abstention from an act to which the obligation relates. It must be possible, lawful, and determined or capable of determination.

The subject matter may be individually specified, such as the sale of a particular property, or specified by type, such as the supply of a quantity of goods meeting defined specifications. Certain contractual effects vary depending on the nature of the subject matter and the manner in which it is identified.

3. Capacity of the Contracting Parties

For a legal act to be valid, the contracting party must possess the capacity required to conclude it. The applicable rules vary according to the person’s age, condition, and the extent of the benefit or harm arising from the contract.

The acts of persons lacking capacity or possessing limited capacity are subject to rules designed to protect their interests. A lack of capacity may result in the transaction being void or voidable, depending on the nature of the case and the applicable statutory rule.

4. Legality of the Contract

The subject matter and content of the contract must be lawful. It is not valid to agree on an obligation prohibited by law, a term that violates a mandatory provision, or an effect that conflicts with public order.

The parties remain free to determine the terms of the contract within the limits established by law. They may regulate the details of their relationship in a manner suited to their interests, provided that the agreement does not contain a statutory violation.

Validity of Intention When Concluding the Contract

A contract may appear to have been formed through offer and acceptance, while the intention of one party has in fact been affected by a defect that undermines the validity of that party’s consent.

The principal defects of intention include:

1. Mistake

A mistake occurs where a contracting party’s consent is based on an incorrect understanding of a material fact and that understanding influenced the decision to contract.

Not every mistake produces the same legal effect. The mistake must be material in light of the circumstances and nature of the contract and the extent to which it affected the party’s intention.

2. Misrepresentation

Misrepresentation occurs through the use of fraudulent means or the provision of misleading information that induces a party to enter into a contract that would not otherwise have been concluded.

Misrepresentation may result from a positive act, and it may also arise from concealing a material fact where the nature of the transaction or good faith requires disclosure.

3. Duress

Duress exists where a contracting party is subjected to a threat that creates fear and compels the party to enter into the contract without free choice.

The effect of duress is assessed by reference to the person’s circumstances, the nature of the threat, and its ability to influence that person’s intention.

Binding Force of the Contract

A valid contract binds its parties according to its terms. No party may revoke or amend it unilaterally unless the contract or the law permits this.

The binding force of contracts protects the stability of transactions because each party bases its decisions on the expectation that the other party will perform its obligations. This includes primary obligations, such as delivery or payment, and ancillary obligations, such as confidentiality, cooperation, provision of information, and refraining from acts that obstruct performance.

The binding force of a contract does not mean that every written term is automatically valid. A term that conflicts with a mandatory statutory provision or public order does not become lawful merely because the parties agreed to it.

Performance of the Contract in Good Faith

The Civil Transactions Law requires a contract to be performed in accordance with its terms and in a manner consistent with good faith. The contract is not limited to what is expressly stated; it also includes obligations arising from the law, custom, and the nature of the contract.

Good faith appears in the parties’ practical conduct during performance. Its applications include:

• Providing the data and documents necessary for performance.

• Refraining from obstructing the other party or imposing requirements not included in the agreement.

• Disclosing material facts affecting performance.

• Complying with agreed deadlines and notice procedures.

• Preserving confidential information.

• Refraining from exercising contractual rights with the intention of harming the other party.

Good faith is a standard for evaluating the manner of performance and is not limited to the contract formation stage.

Interpretation of the Contract

Interpretation becomes necessary where contractual wording is ambiguous, capable of more than one meaning, or inconsistent with other provisions.

Where the wording of the contract is clear, its meaning may not be departed from on the pretext of seeking the parties’ intention. Where interpretation is required, the common intention of the parties must be identified, taking into account the nature of the transaction, custom, and the circumstances surrounding the conclusion of the contract.

Interpretation requires the contract to be read as an interconnected whole rather than treating each clause in isolation. The meaning of a provision may be determined by definitions contained in the contract, the scope of work, the method of calculating consideration, or related obligations.

The need for interpretation is reduced where the contract clearly defines:

• The subject matter and scope of the contract.

• The obligations of each party.

• The consideration and payment mechanism.

• The period for performance.

• Delivery and acceptance procedures.

• Cases of delay and breach.

• Conditions for amendment, termination, and rescission.

• Methods of notice.

• The dispute resolution mechanism.

Effects of the Contract between Its Parties

A valid contract produces its effects between the contracting parties. The agreed rights arise, and the obligations become enforceable.

A contract may bind only one party, as in some forms of donation, or it may bind both parties, as in sale, lease, and construction contracts. In bilateral contracts, each contracting party is both a creditor in one respect and a debtor in another.

The debtor must perform the obligation in the agreed manner. Where the debtor refuses to perform, delays performance, or performs incompletely or defectively, the appropriate statutory consequences arise according to the nature of the breach.

Effect of the Contract on Third Parties

As a general rule, a contract does not impose an obligation on a person who was not a party to it. However, a contract may grant a right to a third party in circumstances permitted by law.

This rule is known as the principle of relativity of contractual effect. An agreement between two persons is not by itself sufficient to require a third person to perform an act or bear a responsibility to which that person did not consent.

Certain effects of the contract may extend to universal or particular successors in accordance with the relevant rules. A stipulation for the benefit of a third party is also permissible where its requirements are satisfied.

Breach of Contract

A breach of contract may occur in several forms, including:

• Complete refusal to perform.

• Delay in performance.

• Partial performance.

• Defective performance.

• Failure to comply with agreed specifications or terms.

• Obstructing the other party from performing its obligation.

The statutory consequence of the breach varies according to its seriousness, whether it can be remedied, the nature and terms of the contract, and the resulting damage.

The injured party may be entitled to request specific performance, suspend performance of the corresponding obligation, terminate the contract, or claim compensation, provided that the statutory requirements for the relevant remedy are satisfied.

Rescission of the Contract

Rescission is connected with a breach by one party to a bilateral contract. It terminates the contractual relationship and produces the effects prescribed by law.

Rescission may be judicial, or it may occur pursuant to an express agreement authorizing the creditor to rescind the contract where the debtor breaches the obligation. An agreement providing for rescission does not dispense with formal notice unless the parties expressly agree otherwise.

Upon rescission or automatic dissolution of the contract, the parties are generally restored to the position they occupied before contracting. Where restoration is impossible, the court may award compensation, subject to the special rules applicable to continuing contracts.

Rescission differs from termination. Rescission usually results from contractual breach, whereas termination may result from expiry of the term, agreement between the parties, or the exercise of a right established by the contract or the law.

Invalidity and Avoidance of the Contract

A distinction must be made between a void contract and a voidable contract.

Void Contract

A contract is void where one of its essential elements is absent or where it violates a rule whose breach results in invalidity.

Any interested person may invoke the invalidity of the contract, and the court may declare it of its own motion. Invalidity cannot be cured by ratification of the contracting parties.

Voidable Contract

A voidable contract is formed as a valid and effective contract, but the law grants one of the parties the right to seek its avoidance because of a defect relating to capacity, intention, or another legally recognized ground.

The contract remains effective unless the person entitled to avoidance invokes that right. The right may lapse through ratification or upon expiry of the statutory period.

Termination of the Contract and Extinguishment of the Obligation

The termination of a contract does not always coincide with the extinguishment of every obligation arising from it.

A contract may end upon expiry of its term, completion of its purpose, or rescission, while certain obligations remain in force, such as confidentiality, return of documents, settlement of accounts, and compensation for earlier damage.

An obligation may be extinguished through performance, release, set-off, merger of creditor and debtor, impossibility of performance, or other causes regulated by law.

Determining the legal effect therefore requires distinguishing between termination of the principal contractual relationship and extinction of every obligation arising from it.

Importance of Legal Drafting

The value of a contract becomes apparent during performance and when disputes arise, not only at the time of signature. Precise drafting defines the scope of the relationship, clarifies responsibilities, and prevents uncontrolled expansion in the interpretation of obligations.

Matters requiring particular attention when preparing a contract include:

• Identifying the parties, their capacities, and the authority of their representatives.

• Describing the subject matter precisely.

• Specifying the consideration, taxes, and expenses.

• Defining the stages and deadlines for performance.

• Establishing clear standards for delivery and acceptance.

• Regulating changes to the scope of work.

• Defining delay events and force majeure.

• Regulating liability and compensation.

• Stating the conditions for rescission and termination.

• Determining jurisdiction and the dispute resolution mechanism.

Using a general template that does not account for the nature of the transaction may produce conflicting obligations or gaps that only become apparent after performance begins.

Frequently Asked Questions about Contracts under the Civil Transactions Law

Must a Contract Be in Writing?

As a general rule, a contract is formed by the concurrence of offer and acceptance unless the law requires a specific form or the parties agree that the contract will not be formed except in writing.

Writing nevertheless remains one of the most important means of proving the agreement and defining its content.

May One Party Amend the Contract Unilaterally?

A contracting party may not amend the contract unilaterally unless the contract or the law grants that party a specific right to do so.

Any power of amendment must be exercised within the agreed limits and in accordance with good faith.

What Is the Difference between Rescission and Invalidity?

Invalidity relates to a defect in the formation of the contract or its violation of a statutory rule affecting its validity. Rescission applies to a valid contract where a subsequent breach in performance justifies bringing it to an end.

Does the Contract Bind Non-Parties?

As a general rule, a contract does not impose an obligation on a third party, although it may confer a right on a third party in cases recognized by law.

Does Expiry of the Contract Term Extinguish All Rights?

The contract term may expire while rights or obligations arising during its operation remain outstanding, such as financial entitlements, compensation, confidentiality obligations, and the obligation to return documents.

Conclusion

The Civil Transactions Law establishes a general framework governing contracts from their formation until the end of their effects. It sets out the rules governing consent, interpretation, performance, and good faith, and addresses breach, rescission, invalidity, and the effect of contracts on third parties.

Contractual protection is achieved through the combination of valid formation, precise drafting, and proper performance. A well-drafted contract does more than prove the agreement. It defines the parties’ obligations, regulates risks, and establishes practical solutions for circumstances that may arise during the contractual relationship.
