4.1 Essentials of a valid contract

The law of contract ensures that agreements between parties are legally binding and enforceable. For a contract to be valid under Kenyan commercial law, it must meet specific criteria that demonstrate the parties’ intention to create legal relations and the presence of mutual consent. Businesses, such as SACCOs or county procurement offices, rely on these essentials to validate agreements ranging from service provision to supply contracts.

4.1.1 Offer and acceptance

An agreement begins with an offer, which is a clear proposal made by one party expressing willingness to contract on certain terms. The acceptance is the unconditional assent by the other party to those terms. Both must be communicated effectively for the contract to be formed.

• Offer clarity: The offer must be precise and definite, leaving no ambiguity about the terms. For example, a supplier offering to sell 100 bags of fertilizer at Ksh 5,000 each to a cooperative must state these terms clearly.
• Communication: The offer and acceptance must be communicated to each other; silence generally does not amount to acceptance.
• Mirror image rule: Acceptance must exactly match the terms of the offer. If a hotel agrees to provide conference services but adds extra conditions, it is a counter-offer, not acceptance.
• Time frame: Offers can be revoked before acceptance. For instance, a retailer withdrawing an offer before a buyer accepts it.
• Mode of acceptance: Acceptance can be express (spoken or written) or implied by conduct, such as paying for goods delivered.

4.1.2 Intention to create legal relations

For a contract to be binding, parties must intend that their agreement will be enforceable by law. In commercial dealings, this intention is presumed unless expressly stated otherwise.

• Commercial agreements: Business transactions, like a service contract between a hotel and a catering company, are presumed to have legal intent.
• Social arrangements: Agreements between friends or family members generally lack legal intent and are not enforceable.
• Evidence of intent: Written contracts, signatures, and formal negotiations demonstrate intention.
• Kenyan courts’ approach: Courts examine the context to infer intention, especially where terms are ambiguous.
• Exceptions: Some commercial agreements may expressly exclude legal intent, such as memoranda of understanding.

4.1.3 Consideration

Consideration refers to the value exchanged between parties, which can be money, goods, services, or a promise to act or refrain from acting. It is essential to support a contract’s enforceability.

• Mutual exchange: Both parties must provide consideration; a one-sided promise is generally not enforceable.
• Adequacy vs sufficiency: The law requires consideration to be sufficient but not necessarily equal in value. For example, paying Ksh 10,000 for a service worth Ksh 15,000 is valid.
• Past consideration: Consideration must be given in return for the promise, not for something already done.
• Executory and executed consideration: Consideration can be a future promise or something already performed.
• Nominal consideration: Even a small token, such as Ksh 1, can suffice to validate an agreement.

4.1.4 Capacity to contract

Parties entering a contract must have the legal capacity to do so. This ensures that vulnerable individuals are protected from exploitation.

• Age of majority: Persons under 18 years in Kenya generally lack capacity to contract, except for necessities.
• Mental capacity: Persons of unsound mind cannot form valid contracts.
• Corporate entities: Companies must act within their legal powers and authority.
• Disqualified persons: Insolvent persons or those disqualified by law cannot validly contract in certain circumstances.
• Kenyan legal safeguards: Courts may set aside contracts entered without proper capacity.

4.1.5 Legality of object and form

The contract’s purpose must be lawful, and certain contracts must comply with statutory formalities to be valid.

• Legal purpose: Contracts involving illegal activities, such as smuggling or bribery, are void.
• Public policy: Agreements that offend public policy, for example, contracts restricting trade unreasonably, are unenforceable.
• Written contracts: Some contracts, like sale of land or guarantees, must be in writing under Kenyan law.
• Formalities: Signing, witnessing, and registration requirements may apply depending on the contract type.
• Compliance with regulations: Business contracts must observe sector-specific laws, such as the Competition Act.

Chapter Summary

This chapter explored the essentials of a valid contract, emphasizing the necessary elements that must be present for an agreement to be legally binding. It then examined various types of contracts, including express and implied, unilateral and bilateral, valid, void and voidable, as well as specialty and simple contracts, along with contracts uberrimae fidei which require utmost good faith. The methods of discharging contracts were discussed, highlighting how contractual obligations can be terminated. Remedies available for breach of contract were outlined to show how the law provides recourse for non-performance. The chapter also covered the concept of acceptance as a critical step in forming a contract, followed by the role of consideration as the value exchanged between parties. Contractual capacity was analyzed to determine who is legally competent to enter into agreements. Terms of contract were detailed to explain the rights and duties agreed upon, while vitiating elements were identified as factors that can undermine contract validity. Finally, breach of contract was examined to understand the consequences when contractual obligations are not fulfilled.
