A Direct Primer for Foreign Investors and Businesses on the Essentials of Kenya’s Law of Contract Act (Cap. 23) and the Key Differences from Common Law Jurisdictions

The Trap That Catches Foreign Investors

Kenya is one of Africa’s most dynamic investment destinations. A growing middle class, an ambitious infrastructure programme, a young tech-savvy population, and the continent’s most sophisticated financial hub in Nairobi make it an obvious target for foreign capital.

Every year, thousands of commercial contracts are signed in this city by parties who assume — quite reasonably — that a contract is a contract. After all, Kenya’s legal system is based on English common law. Most of the world’s major trading nations use common law too. Surely the rules must be familiar?

They mostly are — but not entirely. Kenya’s Law of Contract Act (Cap. 23), enacted on 1st January 1961 and most recently revised in 2022, adopts English common law as the foundation, then overlays it with local modifications that are unfamiliar to many foreign business people.

Fail to understand those modifications, and you could find that a deal you thought was binding is unenforceable, a dispute you expected to resolve quickly drags through the courts for years, or a remedy you believed you had is simply unavailable under Kenyan law.

This article provides a clear, practical guide to the essentials. It is written for business owners, CFOs, in-house counsel, and executives who operate in Kenya or are considering doing so.

It avoids unnecessary legal jargon. Where cases from the Kenyan courts are cited, they are real decisions available on the Kenya Law database at www.kenyalaw.org.

 

1. The Legal Foundation: What Cap. 23 Actually Says

The Law of Contract Act (Cap. 23) is a short statute — only four operative sections — but its reach is enormous. Section 2(1), which is the cornerstone of all Kenyan contract law, provides:

“The common law of England relating to contract, as modified by the doctrines of equity, by the Acts of Parliament of the United Kingdom applicable by virtue of this section, shall extend and apply to Kenya.”

This is the operative provision that anchors Kenyan contract law to England. It means that doctrines such as offer and acceptance, consideration, intention to create legal relations, capacity, and the rules on misrepresentation, duress, and undue influence all derive from English common law and are directly applicable in Kenya.

However, Section 2 also incorporates specific modifications. The Schedule to the Act applies, among other things, the UK’s Law Reform (Frustrated Contracts) Act 1943. This is important: it means the doctrine of frustration, including the rules on apportioning losses between parties when a contract is frustrated, applies in Kenya by direct statutory importation.

Section 3 is the other provision foreign investors must understand thoroughly. It imposes specific writing requirements on certain categories of contracts. As amended by the Business Laws (Amendment) Act 2020 and the Business Laws (Amendment) (No. 2) Act 2021, Section 3(3) requires that any contract for the disposition of an interest in land must be (a) in writing, (b) signed by each party, and (c) witnessed by a person present at the time of signing. A contract for land that does not meet these requirements cannot be sued upon in any Kenyan court.

 

2. The Building Blocks of a Valid Contract in Kenya

Every enforceable contract in Kenya — whether between a Nairobi entrepreneur and a London supplier, or two Kenyan companies — must satisfy the same fundamental requirements inherited from English common law. These are:

(a) Offer and Acceptance

A valid contract requires a clear offer by one party and an unequivocal acceptance by the other. Any acceptance that introduces new terms is treated as a counter-offer, not an acceptance, and kills the original offer.

This was applied directly by the Kenyan High Court in Nairobi Civil Suit E321 of 2022, where the court, applying the earlier Court of Appeal decision in Nairobi Homes Ltd v Major Bastur Kalyan (CA No. 30 of 1985), found that where the consideration remained unclear and a counter-offer was met with silence rather than clear acceptance, there was no binding contract.

The court stated that where fundamental terms such as price are unresolved, an agreement is void for uncertainty.

CASE REFERENCE: Nairobi Homes Ltd v Major Bastur Kalyan CA No. 30 of 1985, Court of Appeal of Kenya Where an agreement is uncertain on a fundamental term such as the payment of the purchase price — including the time and manner of payment — the entire agreement is void for uncertainty. Neither party can be held in breach, and no damages are available from the abortive agreement.

(b) Consideration

Consideration is the price paid for a promise. In Kenya, as in England, a promise is not binding unless it is supported by consideration — something of value flowing from the promisee to the promisor. The Court of Appeal restated this requirement in William Muthee Muthamia v Bank of Baroda (2014) eKLR, which was applied by the Nairobi High Court in Morjaria v Patel [2025] KEHC 2930. The court in that case confirmed that a claimant must prove offer, acceptance, and consideration before any claim for breach can succeed.

(c) Intention to Create Legal Relations

Not every agreement is a contract. Social or domestic arrangements are generally presumed not to be legally binding. Commercial agreements between businesses, on the other hand, are presumed to be intended as legal contracts. Foreign investors should be aware that informal emails, WhatsApp messages, and oral commitments made in business meetings may nonetheless give rise to binding contractual obligations if the context shows commercial intent and the elements of contract are satisfied.

(d) Capacity

Parties to a contract must have legal capacity. Companies must be properly registered and authorised to enter the transaction in question. Individuals must be of majority age (18 years in Kenya) and of sound mind. A contract entered into by a minor is generally voidable at the minor’s option under Kenyan law.

(e) Legality

A contract whose object or consideration is illegal, immoral, or contrary to public policy is void and unenforceable. This is of particular relevance in regulated sectors such as banking, insurance, and telecommunications, where contracts may require prior regulatory approval.

Foreign investors entering joint ventures or concession agreements in regulated industries should always verify that the proposed arrangement does not require a licence or approval that has not been obtained.

3. Writing Requirements: Where Kenya Parts Ways with Pure Common Law

In pure English common law, the general rule is that contracts can be oral. Writing is the exception, required only for specific categories (such as contracts for the sale of land under the Law of Property Act 1925 in England).

Kenya follows this general rule, but Section 3 of Cap. 23 has been significantly expanded through amendments in 2020 and 2021, and the writing requirement for land contracts is now more demanding than many foreign investors expect.

Under Section 3(3) of the Law of Contract Act (as amended), no suit may be brought upon a contract for the disposition of an interest in land unless:

• The contract is in writing, reduced to a formal document signed by the parties;
• Each party’s signature has been witnessed by a person who was physically present at the time of signing; and
• The terms are fully set out in the document or incorporated by reference to an identified external document.

Section 3(5) confirms that the terms of a contract may be incorporated by reference — meaning a master agreement can incorporate terms from a schedule or another document. However, the reference must be clear and specific. Vague references to “standard terms” without identifying the document may not suffice.

Section 3(6) introduces electronic signatures into Kenyan contract law. An “advanced electronic signature” as defined in the Kenya Information and Communications Act (Cap. 411A) satisfies the signature requirement. This is particularly significant for cross-border commercial transactions: properly authenticated e-signatures under Kenyan law are valid for most commercial contracts. However, for contracts involving the disposition of an interest in land and the formal execution of documents by body corporates, specific requirements under the Companies Act (Cap. 486) continue to apply.

The practical lesson for foreign investors: any transaction involving Kenyan real estate, whether a purchase, a long-term lease, a charge, or an assignment, must be properly documented and witnessed before it has any legal force. The High Court of Kenya has consistently refused to enforce oral or insufficiently documented land agreements, no matter how compelling the evidence of the parties’ intentions may be.

4. Key Differences from Other Common Law Jurisdictions

Foreign investors from the United Kingdom, the United States, Australia, Canada, India, or other common law countries will find Kenyan contract law broadly familiar. But the following differences are significant enough to cause real commercial harm if overlooked.

4.1 No General Damages for Breach of Contract

This is perhaps the most important practical difference between Kenyan contract law and the expectations of many foreign business people. In Kenya, it is settled law that general damages — a lump-sum award for the overall suffering caused by a breach — are not available as a remedy for breach of contract.

The Court of Appeal stated this plainly in Joseph Urigadi Kedeva v Ebby Kangishal Kavai (Kisumu Civil Appeal No. 239 of 1997), a principle repeatedly applied in the High Court, including in Civil Suit 4 of 2019 at the Nairobi High Court (Lady Justice A. Ong’injo, 2021), where the court confirmed: “There can be no general damages for breach of contract.”

CASE REFERENCE: Joseph Urigadi Kedeva v Ebby Kangishal Kavai Kisumu Civil Appeal No. 239 of 1997, Court of Appeal of Kenya Where breach of contract is established, the proper remedy is an award of special damages, specifically pleaded and specifically proved. General damages — the type available for tortious wrongs such as negligence — are not available for breach of contract.

What this means for you: if you are entering a commercial contract in Kenya and you want protection for losses that are difficult to quantify in advance — loss of business opportunity, reputational damage, management time — you must negotiate liquidated damages clauses into your contract. Under such a clause, the parties agree in advance on a fixed or formula-based sum that becomes payable upon specific breaches.

A well-drafted liquidated damages clause is your primary contractual insurance policy under Kenyan law.

The rule on special damages is equally strict. Special damages must be specifically pleaded in the court papers and specifically proved by evidence. The court in Dormakaba Limited v Architectural Supplies Kenya Limited [2021] KEHC 210 confirmed that every failure to perform a primary obligation is a breach, but the injured party bears the burden of proving their actual financial loss with specificity. Courts do not award damages that are speculative or inadequately supported by documentary evidence.

 

CASE REFERENCE: Dormakaba Limited v Architectural Supplies Kenya Limited [2021] KEHC 210 (KLR) (Commercial and Tax Division), High Court of Kenya Every failure to perform a primary obligation is a breach of contract. However, to successfully claim damages, a plaintiff must show: (a) a contract exists; (b) the contract was breached by the defendant; and (c) the plaintiff suffered actual, provable loss as a result of the breach. Damages are intended to compensate, not to punish.

4.2 Frustration of Contract: The Kenyan Position

The doctrine of frustration discharges both parties from further performance of a contract when an unforeseen event makes performance impossible, illegal, or radically different from what was contracted for. This doctrine applies in Kenya by virtue of the Law of Contract Act incorporating the UK Law Reform (Frustrated Contracts) Act 1943.

Kenyan courts have adopted a carefully limited approach to frustration. In Dormakaba Limited v Architectural Supplies Kenya Limited [2021] KEHC 210, the court (drawing on Davis Contractors Ltd v Fareham UDC [1956], which applies in Kenya via the common law) held that frustration must meet all of the following conditions:

• Performance must have become impossible, illegal, or radically different — not merely more difficult or more expensive;
• The supervening event must have occurred without the fault of either party;
• The event must have been unforeseeable and outside the contemplation of the parties at the time of contracting;
• The doctrine must not be used to escape a bad bargain — increased cost or inconvenience alone is never sufficient; and
• Frustration is automatic — it ends the contract immediately by operation of law.

The doctrine is applied narrowly. In Civil Appeal 55 of 2016, the Court of Appeal confirmed that frustration “must be kept within very narrow limits” and that the change in circumstances must be “fundamental” rather than merely inconvenient.

A change in immigration law that made a contract of employment impossible to perform was held to be a potentially frustrating event in that case, precisely because it was outside both parties’ control and made the contractual obligation incapable of performance in the way originally contemplated.

Foreign investors should note that the consequences of frustration in Kenya — governed by the incorporated 1943 Act — allow courts to apportion pre-frustration losses between the parties, recover money paid before frustration, and grant compensation for valuable benefits conferred. This is more sophisticated than pure common law frustration, where money paid before frustration was often simply lost.

4.3 Implied Contracts and Conduct

Kenyan courts recognise contracts implied from conduct. The High Court in Civil Suit E321 of 2022 confirmed that an implied-in-fact contract is inferred from the behaviour, interactions, and established relationship between parties, demonstrating a collective intent to form a contract, even where no formal written agreement exists.

For foreign investors, this has a dual significance. On the positive side, it means that where a Kenyan counterparty has acted in a way that clearly demonstrates acceptance of an obligation — receiving payment, commencing performance, or acknowledging a debt — a court may find a binding contract even without a signed document.

On the cautionary side, your own conduct matters: allowing a Kenyan party to perform services on your behalf without a formal contract may, in certain circumstances, give rise to an implied obligation to pay a reasonable price.

4.4 Contracts Not Under Seal Are Valid

One specific modification introduced by Section 2(1) of Cap. 23 is the proviso that no contract in writing shall be void or unenforceable merely because it is not under seal. In England historically, deeds required a seal. In Kenya, a written commercial contract signed by the parties is fully enforceable without any seal, wax, or formal execution beyond signature and, where required, witnessing.

5. Misrepresentation, Duress, and Undue Influence

A contract that appears valid on its face may nonetheless be set aside if it was induced by misrepresentation, duress, or undue influence. Kenyan courts apply English common law principles in this area.

In Civil Appeal E040 of 2020, the High Court defined fraudulent misrepresentation as a false statement that is known to be false or is made recklessly, without knowing or caring whether it is true, and intended to induce a party to detrimentally rely on it.

In that case, a seller who failed to disclose third-party claims over a motor vehicle being sold was held to have committed fraudulent misrepresentation, rendering the contract voidable and grounding a claim for damages.

On duress, the High Court in Morjaria v Patel [2025] KEHC 2930, citing National Bank of Kenya Ltd v Pipeplastic Samkolit (K) Ltd & Another [2001] eKLR, confirmed that contracts are binding on the parties’ agreed terms unless coercion, fraud, or undue influence is demonstrated. An allegation of duress must be supported by evidence; the mere assertion that a cheque was issued under duress — without supporting proof — is insufficient to avoid an obligation.

For foreign investors, the practical importance of this area is acute in two contexts: first, in joint venture negotiations where local partners may have significantly greater knowledge of local market conditions; and second, in procurement and tendering processes where undue pressure from counterparties may affect your consent. Ensuring that all negotiations are properly documented and that your advisers are present is the best protection.

6. Dispute Resolution: What Happens When Things Go Wrong

6.1 Litigation in Kenyan Courts

Kenya has a tiered court system. Commercial disputes are typically heard in the High Court’s Commercial and Tax Division, or in the magistrates’ courts for smaller claims. Appeals go to the Court of Appeal, and from there to the Supreme Court on constitutional points.

Kenyan litigation can be slow. The courts handle large caseloads, and complex commercial cases may take two to four years from filing to final judgment at the High Court level. Judgment enforcement is generally effective within Kenya, though not always straightforward against parties who have moved assets offshore.

6.2 Arbitration: The Preferred Route for Foreign Investors

Kenya is a signatory to the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards. This means that an international arbitral award — whether made under the rules of the ICC, LCIA, ICSID, or the Nairobi Centre for International Arbitration (NCIA) — is enforceable in Kenya as if it were a judgment of the High Court. This is a significant protection for foreign investors.

For any commercial contract with a Kenyan party involving significant value, a well-drafted arbitration clause is strongly recommended. The clause should specify the seat of arbitration, the governing rules, the number of arbitrators, and the language of proceedings. It should also specify clearly which law governs the arbitration agreement itself — which may differ from the law governing the main contract.

Kenya’s Arbitration Act (Cap. 49) is based on the UNCITRAL Model Law. Kenyan courts have generally been supportive of arbitration and reluctant to intervene in arbitral proceedings except on the limited grounds permitted by the Act.

6.3 Mediation

Kenya has introduced a court-annexed mediation programme for commercial cases. Under this programme, certain commercial disputes are referred to mediation before proceeding to full trial. Mediation preserves business relationships, is confidential, and often produces faster, more commercially practical outcomes than litigation. For foreign investors who need to maintain an ongoing commercial relationship with their Kenyan counterparty, mediation is worth considering as a first step even where it is not mandatory.

7. Governing Law and Jurisdiction Clauses

One of the most consequential decisions you make when entering a Kenyan contract is the choice of governing law and jurisdiction. Many foreign investors prefer to choose English law or the law of another familiar jurisdiction. This is generally permissible for international commercial contracts under Kenyan law, and Kenyan courts will usually give effect to a governing law clause.

However, there are important exceptions. Certain types of contracts — particularly those involving Kenyan land, employment of Kenyan employees, or contracts that are wholly to be performed in Kenya and involve Kenyan consumers — may be subject to mandatory Kenyan law provisions that override an express choice of foreign law. A choice-of-law clause does not, for example, allow parties to contract out of Kenya’s Employment Act, the Land Act, or consumer protection legislation.

A jurisdiction clause (specifying which courts will hear disputes) is equally important. A clause giving exclusive jurisdiction to a foreign court is generally enforceable in Kenya, but enforcing a foreign judgment in Kenya requires a separate recognition process. For this reason, many practitioners recommend an arbitration clause in preference to a foreign court jurisdiction clause, since the New York Convention provides a more streamlined enforcement mechanism.

8. Practical Checklist for Foreign Investors Entering Kenyan Contracts

Based on the legal principles set out above, and on our experience advising multinational corporations and foreign investors in Kenya, Mukamba & Company Advocates recommends that foreign parties address the following before signing any significant commercial contract in Kenya:

• Verify your counterparty’s legal capacity: Confirm that the Kenyan entity is properly incorporated, that its directors are authorised to sign, and that no approvals (board, regulatory, or otherwise) are outstanding.
• Reduce the contract to writing: Even where writing is not legally required, a well-drafted written contract is the most powerful evidence of the parties’ agreement. Never rely on oral assurances alone.
• Include a liquidated damages clause: Given that general damages are unavailable for breach of contract in Kenya, a liquidated damages provision is essential for protecting against hard-to-quantify losses.
• Specify your dispute resolution mechanism: A well-crafted arbitration clause is usually the best choice for significant cross-border transactions. Specify seat, rules, language, and number of arbitrators.
• Address governing law carefully: If you choose a foreign law, take advice on whether any mandatory Kenyan law provisions will override your choice in relation to any aspect of the contract.
• Document everything: Under the Evidence Act, whoever asserts a fact must prove it (Section 107). The party who keeps the best records wins the most disputes.
• For land transactions, comply strictly with Section 3: Ensure that all contracts involving an interest in land are in writing, signed, and witnessed. Oral land agreements have no legal force in Kenya.
• Take local legal advice before you sign: The time and cost of pre-contract legal review is always less than the time and cost of litigation.

Conclusion

Kenya’s Law of Contract Act (Cap. 23) provides a solid, familiar common law framework for commercial transactions — but it has its own distinct character. The unavailability of general damages, the strict writing requirements for land contracts, the narrow but significant doctrine of frustration, and the practical realities of dispute resolution in Kenya all create a legal environment that rewards careful, locally-informed legal drafting.

The good news is that these rules are clear, well-established in the case law, and entirely manageable with proper advice. A contract that is well-drafted under Kenyan law — with appropriate representations, a comprehensive liquidated damages regime, a workable dispute resolution clause, and attention to the specific statutory requirements — gives a foreign investor strong protection and a clear path to enforcement if things go wrong.
