Contract Law in Malaysia: A Practical Guide to Contracts, Agreements and Legal Rights

1. What Is a Contract?

We enter into contracts all the time, ofter without ever realising it.

If you’ve ever bought something from a store, hailed a taxi or stayed at a hotel, you’ve entered into a contract.

Understanding how contracts work can help you avoid disputes, protect your rights, and make better decisions.

In this guide, I’ll break down the basics of contract law in Malaysia in plain English.

1.1 Simple Definition of a Contract

At its most basic level, a contract is a binding and legally enforceable agreement between two or more parties.

Once a contract is signed by both parties and all elements of a valid contract are present, the law will find that a legally binding contract exists.

In a valid contract, if one party fails to perform their obligations, the other party may be able to take legal action to enforce the agreement or claim compensation.

In Malaysia, contract law is primarily governed by the Contracts Act 1950.

While the legal rules surrounding contracts can sometimes appear complicated, the underlying idea is actually quite simple: when people make promises that are intended to have legal consequences, the law may require those promises to be honoured.

1.2 Must a Contract Always Be In Writing?

As a matter of best practice, a contract should always be in writing as this would serve as the best evidence of the terms agreed to between the contracting parties.

However, under Malaysian contract law, there is no requirement that a contract must be in writing. As long as the essential elements of a contract are present, even an oral or verbal contract can be legally enforceable.

For example, if you agree to hire someone to paint your house for an agreed price and they agree to perform the work, a contract may exist even if nothing was written down.

When disputes arise, it is often much easier to prove the terms of a written agreement than to rely on conflicting recollections of a verbal conversation. If there are no written terms, parties will have to rely on other forms of proof that a contract exists (e.g. conduct, correspendence, etc.)

1.3 Are Contracts and Agreements The Same?

As a general rule, All contracts are agreements but not all agreements are contracts. I know this might sound confusing, let me explain.

Despite the fact that even legal professionals use the terms “Contract” and “Agreement” interchangably at times, the Contracts Act 1950 distinguishes “Contracts” from “Agreements”.

According to Sectio 2(e) of the Contracts Act, where there is a promise (a promise is formed when there is an offer by a promisor which is accepted by a promisee) and consideration in exchange for the promise by the promisee, then there is an agreement.

An agreement is not automatically legally binding and enforceable. Only once the necessary elements of a contract are fulfiled, the agreement becomes a legally binding contract.

The Contracts Act 1950 lays down the basic elements of a valid contract, which are:

• Offer and acceptance (a.k.a. promise)
• Consideration
• Free consent
• Lawful object

I will delve deeper into the elements of a valid contract below.

1.4 Common Contracts In Malaysia

The following are examples of contracts that most Malaysians encounter and should know about:

1. Sale and Purchase Agreement (SPA)
2. Housing Loan Agreement
3. Tenancy Agreement
4. Employment Agreement

1.5 Understanding Contracts Can Save You Costly Mistakes

It is my personal mission to help others understand the contracts they enter into in plain English. Over the course of my legal practice, I’ve seen many legal disputes arise because people sign contracts without fully understanding what they are agreeing to.

Before signing any agreement, it is always wise to understand:

• Your rights and obligations
• The other party’s rights and obligations
• Deliverables
• Termination rights
• Liability provisions
• Dispute resolution mechanisms

Don’t take the easy way out by signing a contract blindly – it can come back and bite you in the rear! A few minutes spent reviewing a contract can often prevent months of disputes later.

2. What Makes a Contract Legally Valid in Malaysia?

We enter into agreements all the time but not every agreement results in a legal and valid contract.

Under the Contracts Act 1950, not every agreement is enforceable. An agreement only becomes a legally binding contract when it satisfies the legal requirements recognised by Malaysian law.

In practical terms, a valid contract generally requires five essential elements:

• Offer and acceptance
• Consideration
• Intention to create legal relations
• Free consent and capacity to contract
• Legality of the agreement

These elements work together. If one of them is missing, the contract may be unenforceable, void or voidable.

We’ll explore each element throughout this guide, beginning with the foundation of every contract i.e. offer and acceptance.

2.1 Offer and Acceptance

Every contract begins with one party making an offer and another accepting it.

Under the Contracts Act 1950, an “offer” is referred to as a proposal. Once the other party accepts the proposal (offer), it becomes a promise (section 2(b)).

It sounds simple, but a surprising number of contract disputes arise because parties disagree about whether an offer was ever made, whether it was accepted, or whether negotiations had actually concluded.

Courts do not simply ask whether the parties believed they had a deal.

Instead, they objectively examine the parties’ words and conduct to determine whether a legally enforceable agreement came into existence.

Understanding this concept can help prevent costly misunderstandings, particularly in business transactions, property deals and commercial negotiations.

Related reading: Proposal vs Promise Under the Contracts Act 1950: What’s the Difference?

2.1.1 What Is an Offer?

An offer is a clear expression by one party of their willingness to enter into a contract on specified terms, with the intention that it becomes legally binding once accepted.

The person making the offer is known as the offeror, while the person receiving it is the offeree.

For example:

• “I’ll sell you my car for RM40,000.”
• “I’ll renovate your office for RM25,000.”
• “I’ll lease you this shop for RM3,000 per month for three years.”

These are examples of offers because the parties have proposed definite terms capable of immediate acceptance.

In contrast, statements that merely invite discussion or negotiation are usually not offers.

Whether something amounts to an offer depends on substance rather than the label used.

2.1.2 An Offer Must Be Clear and Certain

For an offer to create legal consequences, its essential terms must be reasonably certain.

Generally, this means identifying matters such as:

• the parties involved;
• the subject matter;
• the price or method of determining it; and
• any essential contractual obligations.

If key terms remain uncertain or are still being negotiated, there may not yet be a binding contract.

This issue frequently arises where parties sign “letters of intent” or exchange emails that leave important matters to be agreed later.

2.1.3 Invitation to Treat: Not Every Advertisement Is an Offer

One of the biggest misconceptions in contract law is that every advertisement or displayed price is automatically an offer.

It usually is not.

Most advertisements, catalogues, price lists and goods displayed in shops are legally regarded as an invitation to treat.

An invitation to treat is simply an invitation for others to make offers.

For example:

• Products displayed on supermarket shelves.
• Restaurant menus.
• Property listings.
• Online marketplace listings.
• Most advertisements.

When you take a product to the cashier, you are generally making the offer to purchase.

The retailer then decides whether to accept or reject that offer.

This principle allows businesses to correct pricing mistakes, refuse sales in appropriate circumstances and manage inventory without automatically becoming contractually bound.

One of the leading English authorities frequently referred to in Commonwealth contract law is Pharmaceutical Society of Great Britain v Boots Cash Chemists (Southern) Ltd, where the court held that goods displayed on supermarket shelves constituted an invitation to treat rather than an offer.

Similarly, in Fisher v Bell, displaying a flick knife in a shop window was held to be an invitation to treat rather than an offer for sale.

Although these are English decisions, Malaysian courts continue to regard them as persuasive authorities when applying common law principles of contract formation.

2.1.4 What Counts as Acceptance?

Acceptance is the unqualified or unequivocal agreement to every term of the offer.

Once acceptance takes place, an agreement is generally formed.

Acceptance must correspond exactly with the offer.

For example:

“I accept your offer to purchase your Perodua Myvi for RM40,000.”

This is a valid acceptance.

However, if the response changes the terms, it is no longer an acceptance.

2.1.5 A Counter-Offer Rejects the Original Offer

Suppose someone offers to sell you their Perodua Myvi for RM40,000.

You reply:

“I’ll buy it for RM38,000.”

Many people assume negotiations are continuing.

Legally, however, this response is defined as a counter-offer.

A counter-offer rejects the original offer and replaces it with a new one. In other words, once the counter offer of RM38,000 was made the original offer of RM40,000 can no longer be accepted unless the offeror renews it.

This principle was established in the landmark English case of Hyde v Wrench, which remains one of the most influential authorities on counter-offers and is commonly cited in Malaysian contract law discussions.

2.1.6 Acceptance Must Be Communicated

As a general rule, acceptance only becomes effective when it is communicated to the offeror.

Simply deciding internally that you accept an offer is insufficient.

Likewise, remaining silent will generally not amount to acceptance.

This principle was firmly established in Felthouse v Bindley, where the court held that silence alone cannot constitute acceptance.

Today, communication may occur through:

• email;
• WhatsApp messages;
• signed agreements;
• telephone calls;
• letters; or
• conduct that clearly indicates acceptance.

In commercial practice, disputes often arise over whether emails or WhatsApp messages actually amounted to acceptance. Courts will examine the entire course of negotiations rather than relying on isolated messages.

2.1.7 Can an Offer Be Withdrawn?

Yes.

Under Malaysian law, an offer may generally be revoked at any time before acceptance, provided the revocation is effectively communicated to the offeree.

This principle is expressly recognised under section 5 of the Contracts Act 1950.

Once a valid acceptance has taken place, the offer may no longer be withdrawn because if a binding contract has already come into existence.

However, no contract can be formed if the offer had already been revoked before acceptance.

The timing of communication can therefore become critical in contract disputes.

2.1.8 The Postal Rule (A Limited Exception)

One well-known exception to the usual communication rule is the postal rule.

Where acceptance is properly communicated by post, acceptance may become effective once the acceptance letter is posted rather than when it is received.

This rule originated from the English case of Adams v Lindsell.

However, its practical importance has significantly diminished in modern commerce.

Today, most contracts are concluded through:

• email;
• electronic signatures;
• instant messaging;
• online platforms; or
• face-to-face negotiations.

Whether the postal rule applies will depend on the facts of each case and the parties’ chosen method of communication.

2.1.9 Key Takeaways

Offer and acceptance form the cornerstone of every valid contract.

Without a clear offer and an unconditional acceptance, there is generally no enforceable agreement, regardless of how genuine the parties’ intentions may have been.

The legal distinction between an offer, an invitation to treat, a counter-offer and an acceptance may seem technical, but these concepts determine whether a contract actually exists and they frequently decide the outcome of contract disputes before Malaysian courts.

2.2 Consideration

One of the most important requirements of a legally enforceable contract in Malaysia is consideration. In simple terms, each party must give or promise something of value in exchange for the other party’s promise.

Without consideration, many agreements are simply promises that the law will not enforce.

This principle is reflected in the Contracts Act 1950 and has been recognised by Malaysian courts for decades.

2.2.1 What Is Consideration?

Section 2(d) of the Contracts Act 1950 defines consideration as something done, abstained from doing, or promised to be done at the desire of the promisor.

In simpler language:

Consideration is the price one party pays for the promise made by the other.

That “price” does not always have to be money.

It could include:

• Paying money
• Delivering goods
• Providing services
• Promising not to sue
• Agreeing not to do something you are legally entitled to do
• Making a promise to perform an obligation in the future

Everyday examples include:

• Paying RM10 for a cup of coffee.
• A contractor renovating your house in exchange for payment.
• An employee agreeing to work in return for salary.
• A landlord allowing occupation of premises in exchange for rent.

In each example, both parties are giving something in return.

2.2.2 Why Does Consideration Matter?

The law generally does not enforce promises that are made purely out of generosity.

Suppose someone says:

“I’ll give you RM100,000 next month because you’ve always been a good friend.”

If nothing is expected in return, that is generally a gift rather than a contract.

Now compare that with:

“I’ll pay you RM100,000 if you renovate my restaurant.”

Here, both parties exchange promises. That exchange creates consideration and forms one of the building blocks of an enforceable contract.

This is why consideration is often described as the bargain between the parties.

2.2.3 Consideration Must Move at the Desire of the Promisor

A frequently overlooked rule is that the act or promise must be done at the request of the promisor.

For example:

You decide to repaint your neighbour’s house without being asked. After seeing the finished work, your neighbour promises to pay you RM5,000.

Generally, your earlier work was not performed at the neighbour’s request, so it may not amount to valid consideration for the later promise.

This principle was famously established in the English case of Durham Cathedral v Lambert (1836) and later affirmed by the Privy Council in Kepong Prospecting Ltd v Schmidt, which remains highly persuasive in Malaysia. The Privy Council held that an act done without the promisor’s request does not constitute consideration for a later promise.

2.2.4 Does Consideration Have to Be Equal?

One of the biggest misconceptions is that consideration must have the same value on both sides.

It does not.

The law is generally not concerned with whether the bargain is fair.

If someone sells their vintage watch worth RM20,000 for RM500 because they urgently need cash, the consideration is still legally valid.

The courts generally do not rewrite bad bargains simply because one party later regrets the price.

2.2.5 Adequacy vs Sufficiency of Consideration

This distinction is one every contract law student learns. Consideration must be sufficient but it need not be adequate. I’ll explain what this means below.

Sufficient Consideration

Consideration must have some legal value.

It cannot be something entirely meaningless.

For example:

• RM1 can be valid consideration.
• A promise to perform services can be valid consideration.
• Agreeing to give up a legal right can also be valid consideration.

As long as the law recognises some value, the requirement is satisfied.

Adequate Consideration

Adequacy refers to whether both sides exchanged equal value.

Generally, the courts do not examine adequacy.

This principle was firmly established in the landmark English case of Chappell & Co Ltd v Nestlé Co Ltd, where chocolate bar wrappers formed part of the consideration for purchasing records. Although the wrappers had little economic value, the House of Lords held that they were nevertheless valid consideration because they formed part of the agreed bargain.

Lord Somervell famously observed:

“A peppercorn does not cease to be good consideration if it is established that the promisee does not like pepper and will throw away the corn.”

Malaysian courts have consistently applied the same principle.

2.2.6 Can Past Consideration Be Valid?

One area where Malaysian law differs from English common law is past consideration.

Under traditional English law, a promise made after an act has already been completed is generally unenforceable because the consideration is “past.”

However, Malaysia adopts a broader statutory approach.

Section 2(d) of the Contracts Act 1950 expressly recognises that consideration may consist of something a promisee has already done, is doing, or promises to do.

This means that past consideration may be valid under Malaysian law, provided the statutory requirements are satisfied.

For example:

A business owner asks you to urgently repair machinery over the weekend.

After you finish the repairs, the owner promises to pay RM8,000.

Because the work was done at the owner’s request, Malaysian law may recognise that earlier act as valid consideration.

This is one of the important distinctions between Malaysian contract law and English common law.

2.2.7 Are There Contracts That Do Not Require Consideration?

Yes.

Although consideration is generally required, the Contracts Act 1950 recognises several important exceptions.

1. Agreements Made Out of Natural Love and Affection

Section 26(a) provides that an agreement made:

• in writing,
• registered where required by law, and
• between parties standing in a near relationship,

may still be enforceable even without consideration.

These situations are relatively uncommon in commercial transactions but may arise within families.

2. Promise to Compensate for Voluntary Services

Section 26(b) recognises promises made to compensate someone who has voluntarily done something for the promisor or something the promisor was legally bound to do.

For example:

A neighbour voluntarily prevents your property from being damaged during a flood. Afterwards, you promise to reward them for their efforts.

In appropriate circumstances, such promises may be enforceable despite the absence of fresh consideration.

3. Promise to Pay a Time-Barred Debt

Section 26(c) allows a debtor to make a written and signed promise to pay a debt that has become unenforceable because the limitation period has expired.

Although the original debt can no longer be sued upon, the new written promise may itself become enforceable.

2.2.8 Practical Advice Before Signing Any Contract

When reviewing a contract for clients, one of the questions I always ask is:

“What is each party actually giving in return?”

If one party receives all the benefits while giving nothing in exchange, it is worth taking a closer look.

In most commercial agreements, whether tenancy agreements, employment contracts, shareholder agreements or sale and purchase agreements, consideration is usually obvious. However, problems often arise where agreements are informal, promises are made after the fact, or parties assume that goodwill alone is enough to create legal obligations.

Understanding consideration helps you distinguish between a legally enforceable contract and a promise that may carry moral weight but little legal effect.

3. How Are Contracts Interpreted in Malaysia?

Even the most carefully drafted contract can become the subject of a dispute. Often, the disagreement isn’t about whether a contract exists but rather it is about what the contract actually means.

Can one clause override another? Can you rely on promises made before signing? What if the written contract says one thing but someone verbally promised something else?

These are common issues in contract disputes. When they arise, Malaysian courts apply well-established principles to determine what the parties intended when they entered into the agreement. Understanding these principles can help you avoid costly misunderstandings and draft contracts that better protect your interests.

3.1 Written Contracts Take Priority

Where parties have recorded their agreement in writing, the written contract is generally the starting point for interpretation. The courts will first examine the words used in the agreement itself, as these usually provide the best evidence of what the parties agreed to.

This is why it is always advisable to ensure that important commercial terms, obligations and promises are properly documented rather than left to verbal discussions or informal emails.

3.2 The Plain Meaning Rule

As a general rule, Malaysian courts give contractual words their ordinary and natural meaning.

If the wording of a clause is clear, the court will usually enforce it as written without trying to rewrite the bargain or rescue a party from a bad deal. The role of the court is to interpret the contract, not create a new one.

3.3 A Contract Must Be Read as a Whole

One clause should never be interpreted in isolation.

Instead, the court considers the contract as a whole, giving effect to all of its provisions wherever possible. A clause that appears unclear on its own may become perfectly understandable when read together with the rest of the agreement.

For this reason, it is important to read every clause before signing rather than focusing only on the commercial terms.

3.4 Commercial Interpretation

Business contracts exist to achieve commercial objectives. Where contractual wording is genuinely ambiguous, Malaysian courts generally favour an interpretation that makes commercial sense and reflects the objective intention of the parties, provided it is consistent with the language of the agreement.

3.5 Can You Use Evidence Outside the Written Contract?

I often encounter this question:

“Can I rely on what was promised before I signed the contract?”

The answer is: it depends.

3.5.1 The General Rule

Under Malaysian contract law, where the parties have reduced their agreement into writing, they generally cannot rely on external evidence to contradict, add to or vary the written terms. This principle is commonly known as the parol evidence rule.

In other words, if the contract clearly states one thing, it is usually difficult to argue that a different verbal agreement should prevail.

3.5.2 Important Exceptions

The rule is not absolute. Malaysian courts may allow evidence outside the written contract in certain situations, including where it is necessary to:

• explain ambiguous wording;
• prove fraud, misrepresentation, coercion or undue influence;
• show that no valid contract was formed; or
• establish a recognised legal exception, such as a collateral contract.

3.6 What Is a Collateral Contract?

Sometimes, a promise made before the main contract is signed is so important that it becomes a separate legally enforceable agreement, known as a collateral contract.

For example, a seller may promise that certain machinery can produce a specified output, and the buyer signs the written agreement based on that assurance. Depending on the facts, that promise may still be enforceable even though it does not appear in the main contract.

3.7 What Is an Entire Agreement Clause?

Many commercial contracts contain an Entire Agreement Clause, which states that the written contract contains the parties’ complete agreement and replaces all previous negotiations, emails and verbal discussions.

These clauses are designed to reduce disputes over alleged promises made before the contract was signed. However, they do not automatically prevent every legal claim, particularly where issues such as fraud or misrepresentation arise.

Read more: What Is an Entire Agreement Clause?

3.8 What Are Exemption Clauses?

An exemption clause (also known as an exclusion or limitation of liability clause) seeks to exclude or limit a party’s legal responsibility if something goes wrong.

These clauses commonly appear in service agreements, software licences, tenancy agreements and other commercial contracts.

However, they are not automatically enforceable. Malaysian courts will consider factors such as whether the clause was properly incorporated into the contract, whether it clearly covers the loss in question and whether any legislation, such as the Consumer Protection Act 1999, affects its validity.

4. Can a Contract Be Cancelled or Set Aside in Malaysia?

One of the most common questions I hear about contracts is:

“I’ve already signed the agreement. Is it too late to get out of it?”

Signing a contract is important, but a signature does not necessarily mean that the contract is beyond challenge. Malaysian contract law recognises several circumstances where an agreement may be void from the outset or where one party may have the right to set aside (rescind) a voidable contract.

For example, problems may arise where someone was pressured into signing, important facts were misrepresented, fraud was involved, or the parties entered into the agreement under a fundamental mistake.

The starting point is usually the Contracts Act 1950, particularly its provisions dealing with consent, capacity, unlawful agreements and the consequences of void and voidable contracts.

4.1 What Is a Voidable Contract?

A voidable contract is different from a contract that was never legally effective in the first place.

Generally, a voidable contract remains valid and binding unless and until the party entitled to avoid it elects to do so.

One of the main reasons a contract becomes voidable is that the consent of one party was not genuinely free.

Section 10 of the Contracts Act 1950 requires, among other things, that parties contract with free consent. Section 14 provides that consent is free when it is not caused by coercion, undue influence, fraud, misrepresentation or mistake, subject to the provisions of the Act.

These concepts sound technical, but they usually arise from very practical situations.

4.1.1 Coercion: “I Was Forced to Sign the Contract”

A contract may be voidable where a person’s consent was obtained through coercion.

Section 15 of the Contracts Act 1950 defines coercion to include committing or threatening to commit an act forbidden by the Penal Code, or unlawfully detaining or threatening to detain property, with the intention of causing a person to enter into an agreement.

Where consent is caused by coercion, the contract is generally voidable at the option of the person whose consent was obtained through that coercion. That person may, depending on the circumstances, seek rescission and consequential restitution.

4.1.2 Undue Influence: When One Party Has Power Over Another

Not every form of pressure amounts to coercion.

Sometimes the concern is that one party was in a position to dominate the will of another and used that position to obtain an unfair advantage. This is dealt with under the doctrine of undue influence in section 16 of the Contracts Act 1950.

It can become particularly relevant where there is a relationship of trust, authority or dependency between the parties.

The important point is that simply regretting a transaction or believing that you received a bad deal is not enough. The circumstances must satisfy the legal requirements for undue influence.

Read more: What Is Undue Influence in Malaysian Contract Law?

4.1.3 Fraud: “I Was Deliberately Lied To”

Fraud goes further than an innocent misunderstanding.

Section 17 of the Contracts Act 1950 covers various forms of fraudulent conduct, including false statements made without belief in their truth, active concealment of facts and promises made without any intention of performing them.

Importantly, silence does not ordinarily amount to fraud, although there are circumstances where a person has a duty to speak or where silence is effectively equivalent to making a representation.

Where fraud caused a party to enter into the contract, the contract may be voidable and remedies may include rescission and, depending on the circumstances, damages.

Read more: Fraud vs Misrepresentation in Malaysian Contract Law: What’s the Difference?

4.1.4 Misrepresentation: What If I Signed Based on False Information?

Misrepresentation is another common reason for challenging a contract.

Broadly speaking, misrepresentation occurs where a false representation induces another person to enter into an agreement, without necessarily involving the dishonest intention required for fraud.

For example, imagine purchasing a business after being given inaccurate information about its operations or assets. If that representation materially influenced your decision to enter into the agreement, the law may provide a remedy.

Section 18 of the Contracts Act 1950 deals specifically with misrepresentation, while section 19 addresses the voidability of agreements where consent was caused by coercion, fraud or misrepresentation. There are, however, important qualifications and exceptions, so not every inaccurate statement gives an automatic right to cancel a contract.

Read more: What Is Misrepresentation in Malaysian Contract Law?

4.1.5 Mistake: What If Both Parties Got Something Wrong?

Mistake works somewhat differently.

A sufficiently fundamental mistake may mean that there was never an enforceable agreement to begin with.

Under section 21 of the Contracts Act 1950, where both parties are under a mistake as to a matter of fact essential to the agreement, the agreement is void.

A unilateral mistake does not generally have the same effect. Section 23 provides that a contract is not voidable merely because one party was mistaken as to a matter of fact, although there are important legal principles and exceptions surrounding particular types of mistake.

4.1.6 What Is the Difference Between a Void and Voidable Contract?

The distinction matters because the legal consequences are very different.

Void Agreement	Voidable Contract
Has no legal effect or ceases to be enforceable as provided by law.	Remains binding unless the entitled party elects to avoid it.
Neither party can generally enforce it as a contract.	The innocent party may choose whether to affirm or rescind it.
Example: certain agreements involving a fundamental mutual mistake.	Example: a contract induced by coercion, fraud or misrepresentation.
Restitution may still be available in appropriate circumstances.	Rescission and restitution may be available.

The practical point is important: “void” and “voidable” do not mean the same thing, even though the words are often used interchangeably outside the legal profession.

4.2 What Is Promissory Estoppel?

There is another situation I occasionally see in contractual disputes.

One party tells the other:

“Don’t worry about that requirement. I won’t enforce it.”

The other party relies on that promise and changes their position. Later, the first party changes their mind and tries to enforce their strict contractual rights.

This is where promissory estoppel may become relevant.

In simple terms, where one party leads another to believe that certain strict legal rights will not be enforced, intends the other party to act upon that position, and the other party does so, equity may prevent the first party from subsequently insisting on those strict rights where it would be inequitable to allow them to do so. Malaysian courts have recognised and applied this equitable doctrine.

For example, imagine a landlord agrees that a tenant may temporarily pay a reduced amount of rent during difficult trading conditions. The tenant relies on that promise. Depending on the circumstances, the landlord may be prevented from suddenly insisting that the tenant was in breach throughout that agreed period.

Promissory estoppel is nevertheless a nuanced doctrine. Traditionally, it operates as a “shield rather than a sword” in other words, primarily as a defence preventing a party from enforcing strict rights rather than as an independent cause of action based purely on a gratuitous promise. This principle has been recognised in Malaysian authorities including Cheng Hang Guan v Perumahan Farlim (Penang) Sdn Bhd and Majlis Amanah Rakyat (MARA) v Tam Seek Hong.

There is also an important Malaysian statutory distinction: in the particular context of accepting a lesser sum in satisfaction of a debt, section 64 of the Contracts Act 1950 may itself apply, meaning it is not always necessary to rely on promissory estoppel.
