Introduction
In the study of contract law, the concept of a ‘term’ is fundamental to understanding the obligations and rights that bind parties to an agreement. Terms of a contract delineate the specific promises and conditions under which the contract operates, and their categorisation plays a crucial role in determining legal remedies in the event of a breach. Broadly, contractual terms are divided into two primary categories: express terms and implied terms. This essay explores these categories in detail, examining the various situations that fall under each and highlighting their significance in the context of UK contract law. By drawing on academic literature and legal principles, the discussion aims to provide a sound understanding of how these terms function within contractual agreements, including their applicability and limitations. The essay will first address express terms, followed by implied terms, before concluding with a summary of key arguments and their implications for legal practice.
1. Express Terms
Express terms are those explicitly agreed upon by the contracting parties, whether articulated orally or documented in writing. These terms form the core of the contractual agreement, as they directly reflect the intentions of the parties at the time the contract is formed (Smith, 2018). Express terms can cover a wide range of matters, including the price of goods, delivery dates, and specific obligations each party must fulfil. Their clarity and specificity make them central to contractual disputes, as courts often prioritise these terms when interpreting the contract.
Several situations fall under the category of express terms. First, written terms in formal contracts—such as those found in sales agreements or employment contracts—are the most recognisable form. These terms are typically drafted with precision to avoid ambiguity, and their inclusion in a signed document often serves as conclusive evidence of the parties’ intentions (Adams and Brownsword, 2019). For instance, a contract for the sale of goods might expressly state that delivery must occur within 14 days, leaving no room for misinterpretation.
Second, oral agreements also constitute express terms, though proving their existence can be more challenging in a legal setting. In cases where a contract is partly written and partly oral, the ‘parol evidence rule’ may come into play, potentially excluding oral terms if they contradict the written agreement (Peel, 2015). However, if the oral term is deemed a collateral contract—meaning it is a separate agreement made to induce entry into the main contract—it may still be enforceable. A typical scenario might involve a seller orally promising a buyer that a product has a specific feature not mentioned in the written contract, which, if relied upon, could form a separate express term.
Lastly, express terms can also arise from pre-contractual statements or negotiations explicitly incorporated into the final agreement. Advertising claims or specific representations made during discussions can become express terms if the parties intend them to be binding (Smith, 2018). For example, a car dealership’s assertion about a vehicle’s mileage, if agreed to be part of the contract, becomes an express term, and any deviation could constitute a breach.
While express terms are critical for their clarity, their interpretation can sometimes be contentious, particularly when ambiguity arises. Courts may then look to the objective intention of the parties, demonstrating a limitation in relying solely on express terms without considering the broader context (Adams and Brownsword, 2019). Nevertheless, express terms remain a cornerstone of contractual agreements due to their explicit nature and direct representation of agreed obligations.
2. Implied Terms
In contrast to express terms, implied terms are not explicitly stated by the parties but are incorporated into the contract either by law, custom, or the presumed intention of the parties. These terms address gaps in the agreement, ensuring fairness and practicality in situations where the parties have not expressly provided for every eventuality (Peel, 2015). Implied terms are essential in maintaining the functionality of contracts and often reflect legal or societal expectations rather than the specific intentions of the contracting parties.
There are several distinct situations under which implied terms arise. Firstly, terms implied by statute are a significant category, particularly in consumer contracts. Under UK law, legislation such as the Sale of Goods Act 1979 imposes implied terms regarding the quality, fitness for purpose, and description of goods sold in the course of business (Sale of Goods Act 1979, c. 54). For instance, Section 14 of the Act implies that goods must be of satisfactory quality, meaning they meet the standard a reasonable person would expect. This statutory protection ensures consumers are not disadvantaged by the absence of express terms covering such issues.
Secondly, terms can be implied by common law, often through judicial decisions that establish precedents. Courts may imply terms to give business efficacy to a contract, meaning the term is necessary for the contract to work as intended by the parties (Andrews, 2016). A classic example is found in The Moorcock (1889), where a term was implied that a wharf owner must ensure the riverbed was safe for docking, as this was essential for the contract’s purpose. This situation demonstrates the judiciary’s role in ensuring contracts are practical, even when the parties have not explicitly addressed certain matters.
Thirdly, terms implied by custom or trade usage fall under this category. In industries with established practices, certain terms are assumed to apply unless expressly excluded. For example, in construction contracts, it might be implied through custom that payment is made in stages upon completion of specific milestones, reflecting standard industry practice (Peel, 2015). However, such customs must be well-known and consistently applied within the relevant trade to be deemed implied.
Lastly, terms implied in fact arise from the specific circumstances of the contract and the presumed intention of the parties. Courts may infer such terms based on what the parties would likely have agreed upon had they considered the issue (Andrews, 2016). This often requires a delicate balance, as the court must avoid rewriting the contract while ensuring it remains fair and workable. For instance, in a lease agreement, a term might be implied that the landlord must maintain the property’s structural integrity, as this is a reasonable expectation.
Despite their utility, implied terms present challenges, as their incorporation can sometimes be contentious, particularly when parties dispute whether a term was necessary or intended. Moreover, over-reliance on implied terms may undermine the principle of freedom of contract, as it introduces obligations not explicitly agreed upon (Smith, 2018). Nonetheless, implied terms remain indispensable for addressing unforeseen issues and upholding fairness in contractual relationships.
Conclusion
In summary, the terms of a contract are broadly categorised into express and implied terms, each serving distinct yet complementary roles in defining contractual obligations. Express terms, encompassing written, oral, and incorporated statements, reflect the explicit intentions of the parties and form the foundation of most agreements. Implied terms, arising from statute, common law, custom, and factual circumstances, fill essential gaps, ensuring fairness and functionality where express provisions are absent. While express terms offer clarity, their interpretation can sometimes be ambiguous, and implied terms, though vital, may introduce unintended obligations. Together, these categories underscore the dynamic nature of contract law, balancing party autonomy with legal and practical considerations. Understanding these terms is critical for legal practitioners and students alike, as they directly impact the enforceability of agreements and the remedies available upon breach. This analysis highlights the importance of precision in drafting contracts while recognising the protective role of implied terms in achieving equitable outcomes.
