When is an agreement legally binding in Malaysia?

Malaysian contract law is codified. That is unusual in the common-law world and it has a practical consequence: for most everyday questions, there is a section you can actually read, rather than a line of cases you have to reconstruct. The Contracts Act 1950 is that code.

The core test

Section 10(1) is the whole of contract formation in a sentence: all agreements are contracts if they are made by the free consent of parties competent to contract, for a lawful consideration and with a lawful object, and are not expressly declared void by the Act.

Four requirements, each with its own machinery elsewhere in the Act: agreement, capacity, consideration, and lawfulness — plus free consent running through all of them.

Section 10(2) adds an important negative: nothing in the section affects any law requiring a contract to be in writing, witnessed or registered. Section 10 does not mean a handshake always works; it means the Contracts Act does not itself impose a writing requirement. Other statutes do — for land dealings, hire-purchase, moneylending, and contracts of service exceeding one month (Employment Act 1955, s 10).

Agreement: proposal and acceptance

Section 2 defines the vocabulary precisely. A proposal is signifying to another your willingness to do or abstain from something, with a view to obtaining his assent (s 2(a)); when accepted it becomes a promise (s 2(b)); every promise or set of promises forming the consideration for each other is an agreement (s 2(e)); an agreement enforceable by law is a contract (s 2(h)), one not enforceable is void (s 2(g)), and one enforceable at the option of only one party is voidable (s 2(i)).

That last distinction is the one most worth internalising. Void means there was never an enforceable contract. Voidable means there is a real contract that one side may choose to unwind — and if that side does nothing, it stays fully binding. Misrepresentation makes a contract voidable; an unlawful object makes it void. The remedies differ accordingly.

Consideration: the price of a promise

Section 2(d) defines consideration as an act, abstinence or promise given at the desire of the promisor — by the promisee "or any other person".

Two Malaysian features surprise people trained on English law.

Consideration may move from a third party. The words "or any other person" are deliberate: you need not be the one who gave the consideration in order to enforce the promise.

Past consideration is good consideration. Section 26(b) validates an agreement without consideration where it is "a promise to compensate, wholly or in part, a person who has already voluntarily done something for the promisor". Illustration (c) makes it concrete: A finds B's purse and returns it; B promises A RM50; that is a contract.

Section 26 also validates two other consideration-free promises: a written and registered promise made on account of natural love and affection between parties in a near relation (s 26(a)), and a written, signed promise to pay a time-barred debt (s 26(c)).

Explanation 2 to section 26 settles the "but it was a terrible deal" argument: an agreement is not void merely because the consideration is inadequate, though inadequacy may be evidence that consent was not freely given.

Capacity

Section 11: every person is competent to contract who is of the age of majority according to the law to which he is subject, is of sound mind, and is not disqualified by any law.

The age of majority is eighteen (Age of Majority Act 1971, s 2).

Section 12 defines soundness of mind functionally, not medically: a person is of sound mind for this purpose if, at the time he makes the contract, he is capable of understanding it and of forming a rational judgment as to its effect on his interests. Subsections (2) and (3) make the test moment-specific in both directions — a person usually of unsound mind may contract in a lucid interval, and a person usually of sound mind may not contract while unsound. Illustration (b) includes someone "so drunk that he cannot understand the terms of a contract".

What the Act does not spell out is the consequence of a minor contracting. That has been settled by case law rather than statute, and the position differs from England. If a minor's contract is in issue, the Act alone will not give you the answer.

Free consent

Section 14 lists five vitiating factors: coercion (s 15), undue influence (s 16), fraud (s 17), misrepresentation (s 18), and mistake (ss 21–23). Consent is "said to be so caused when it would not have been given but for" the factor — a causation test, not a moral one.

The consequences split:

• coercion, fraud or misrepresentation → the contract is voidable at the option of the party whose consent was caused (s 19(1));
• undue influence → voidable at the option of the party whose consent was so caused (s 20);
• mutual mistake as to a matter of fact essential to the agreement → the agreement is void (s 21);
• unilateral mistake as to a matter of fact → the contract is not voidable merely for that (s 23);
• mistake as to Malaysian law → not voidable (s 22), though a mistake as to foreign law is treated like a mistake of fact.

Two points inside section 19 repay attention. Section 19(2) gives a misled party an alternative to rescission: insist the contract be performed and that he be put in the position he would have been in if the representation had been true. And the Exception to section 19 removes voidability where consent was caused by misrepresentation or fraudulent silence and the misled party had the means of discovering the truth with ordinary diligence.

Note also how wide section 18 is. "Misrepresentation" includes a positive assertion of something untrue that the speaker honestly believes (s 18(a)), and "causing, however innocently, a party to make a mistake as to the substance of the thing" (s 18(c)).

Terms and agreements the Act strikes down

• Unlawful consideration or object (s 24). Void where the consideration or object is forbidden by law, would defeat any law, is fraudulent, involves injury to person or property, or is immoral or opposed to public policy. Section 25 extends this: if any part is unlawful, the whole agreement is void.
• Restraint of trade (s 28). "Every agreement by which anyone is restrained from exercising a lawful profession, trade, or business of any kind, is to that extent void." There are only three exceptions — sale of goodwill, and two partnership situations. Malaysia has no general reasonableness test for non-compete clauses of the kind English law applies. A post-employment non-compete that restrains the employee from working in the trade falls squarely within the words of section 28.
• Restraint of legal proceedings (s 29). An agreement that absolutely restricts a party from enforcing his rights by the usual legal proceedings, or which limits the time within which he may do so, is void to that extent. Arbitration clauses are expressly excepted. A clause saying "no claim may be brought more than three months after delivery" is the thing section 29 is aimed at.
• Uncertainty (s 30). Agreements whose meaning is not certain, or capable of being made certain, are void. The illustrations are unusually helpful: "a hundred tons of oil" is void; the same words from a dealer who trades only in coconut oil are not.

Deposits, penalties and "liquidated damages"

Section 75 is the most commercially significant provision in the Act and the least understood. Where a contract is broken and a sum is named in it as payable on breach, or there is any other stipulation by way of penalty, the innocent party is entitled — whether or not actual damage or loss is proved — to receive reasonable compensation not exceeding the amount so named.

Both halves are operative. You do not have to prove loss to get something; but you are not automatically entitled to the stated figure either — you get what the court considers reasonable, capped at that figure. Malaysia therefore does not maintain the English distinction between an enforceable "liquidated damages" clause and an unenforceable "penalty"; section 75 collapses both into one reasonableness inquiry. How that inquiry is conducted is settled by Federal Court case law, which sits outside this corpus.

Related: section 65 requires a party who rescinds a voidable contract to restore any benefit received under it, and section 66 requires anyone who received an advantage under an agreement discovered to be void, or a contract that becomes void, to restore it or compensate for it.

Damages, and how long you have

Section 74(1) gives compensation for loss "naturally arising in the usual course of things" from the breach, or which the parties knew when contracting to be likely to result; s 74(2) excludes "remote and indirect" loss. The Explanation to section 74 carries the duty to mitigate: "the means which existed of remedying the inconvenience caused by the non-performance of the contract must be taken into account."

Contract claims are then subject to the Limitation Act 1953, s 6(1): barred after six years from the date the cause of action accrued — for breach of contract, generally the date of the breach, not the date you discovered it.

Common misconceptions

• "It isn't signed, so there's no contract." Section 10(2) preserves separate writing requirements; it does not create one.
• "My non-compete is fine because it's only six months and one state." Section 28 has no reasonableness test; it has three narrow exceptions.
• "The contract says RM50,000 on breach, so I get RM50,000." Section 75 caps you at that figure and gives you what is reasonable.
• "I never got anything for my promise, so it's unenforceable." Check s 26(b) and (c) first.
• "We both misunderstood, so it's voidable." Mutual mistake as to an essential fact makes it void (s 21); one-sided mistake generally does neither (s 23).
