ICAB CL Business Law · Understand the traps and how to avoid them.
Answering a question about contract formation by asserting that a contract exists simply because the parties signed a document, without identifying offer, acceptance, consideration, and intention to create legal relations as separate elements.
Candidates memorise 'a contract needs offer and acceptance' as a slogan and then treat the signed paper as conclusive, skipping the analytical steps the examiner is marking. The habit comes from reading scenario questions as factual recall rather than element-by-element application.
What to do instead
Before writing, list the four formation elements in the margin and tick each one against the facts. Where an element is missing or doubtful (for example no clear acceptance, or past consideration), say so expressly and state the consequence. Practise by taking three past scenarios and writing a one-line finding for each element before drafting the full answer.
Confusing the rules on invitation to treat with those on offer, so that a display of goods in a shop, an advertisement, or a tender notice is treated as an offer capable of acceptance.
The categories look similar in a scenario and candidates rely on everyday intuition ('they advertised it, so they offered it'). The distinction is tested precisely because it changes who can accept and when liability arises.
What to do instead
Memorise the short list of settled categories: display of goods, advertisements, auctions, tenders, and invitations to negotiate are generally invitations to treat; a response to a specific request can be an offer. For each practice scenario, write one sentence naming the category and the legal effect before analysing acceptance.
Treating acceptance as effective on dispatch in every case, without checking whether the postal rule is excluded or whether the communication is instantaneous.
The postal rule is the most memorable rule in the offer-and-acceptance topic, so candidates over-apply it. They overlook that the rule is a default, displaced by express terms or by the nature of the means used.
What to do instead
Use a two-step check: first identify the means of communication, then ask whether the parties excluded the postal rule expressly or by implication. State the general rule for instantaneous communication (receipt) and the exception (post). Write the rule and its exception from memory at the start of each answer on acceptance.
Describing consideration as 'something of value' or 'a promise for a promise' without applying the requirements that it must move from the promisee and must not be past.
Textbook definitions are easy to reproduce but hard to apply, and candidates stop at the definition. They then miss the issue the scenario is actually testing, such as a pre-existing duty or an act performed before the promise was made.
What to do instead
For every consideration question, run three tests in writing: is the act or promise given in exchange for the other party's promise; did it move from the promisee; was it given before or at the time of the promise. Cite the consequence for each failed test rather than merely naming it.
Treating an exclusion or limitation clause as automatically effective once it is included in the written terms, without addressing incorporation, construction, and any statutory control.
Candidates see the clause in the facts and jump to the conclusion that the party is protected, skipping the sequence of hurdles. The topic rewards a structured approach and penalises conclusion-first answers.
What to do instead
Adopt a fixed three-stage structure: incorporation (reasonable notice, before or at contract, signed document), interpretation (does the wording cover the loss claimed), and statutory or common law control. Answer each stage in its own paragraph even if one stage appears decisive, so the marker can see the reasoning.
Confusing the remedies of damages and specific performance, or awarding damages for every breach without considering remoteness, mitigation, and the requirement of a legitimate interest for equitable relief.
Remedies are often studied last and in a hurry, so candidates collapse them into 'the claimant gets compensated'. They also forget that equitable remedies are discretionary and unavailable where damages are adequate.
What to do instead
Build a remedies checklist: identify the breach, ask what the innocent party has lost, apply the remoteness test, apply mitigation, then ask whether damages are adequate before considering equitable relief. Practise by writing the checklist from memory and applying it to two short scenarios per study session.
Answering a question on agency by stating that an agent binds the principal, without identifying the source of the agent's authority and whether the third party knew of any limitation.
The word 'agent' triggers a single conclusion in candidates' minds. The examiner is usually testing actual versus apparent authority, ratification, or the effect of undisclosed limits, and a general statement earns little credit.
What to do instead
For each agency question, name the type of authority relied on (express actual, implied actual, apparent, or authority by ratification) and state the facts that support it. Then state the effect on the principal and the third party separately. Keep a one-page table of authority types and revise it before the exam.
Describing the separate legal personality of a company in general terms without applying it to the facts, for example to liability of directors, lifting the corporate veil, or capacity to contract.
The principle is taught early and repeated often, so candidates reproduce the phrase 'the company is a separate legal person' and stop. They do not connect it to the specific consequence the question asks about.
What to do instead
After stating the principle, always write 'therefore' and apply it to the named party: who owes the obligation, who can sue, whose assets are at risk. Where the question raises abuse, note the limited and exceptional nature of veil lifting rather than treating it as routine.
Ignoring the question's instruction words and the marks available, producing a long narrative of facts with no clear legal issue, rule, application, and conclusion structure.
Under time pressure candidates write everything they know about the topic in case some of it scores. This consumes time, leaves later questions unanswered, and obscures the reasoning the marker is looking for.
What to do instead
Before writing, underline the instruction word (advise, discuss, compare) and note the mark allocation. Allocate roughly one minute per mark, draft a four-part skeleton (issue, rule, application, conclusion), and answer the question actually asked. Practise timed answers and review whether each paragraph earns its marks.
Citing case names or statutory provisions without stating the principle they establish, or citing them inaccurately, so the reference adds nothing to the analysis.
Candidates learn lists of case names as a shortcut to looking knowledgeable, but the marker awards credit for the rule and its application, not for the name alone. Half-remembered names also invite misstatement.
What to do instead
For every authority you plan to use, write the proposition it supports in one sentence and check it is accurate; if you cannot state the proposition confidently, describe the rule without naming the case. Keep a revision sheet pairing each key authority with its single-sentence rule and test yourself by covering the rule column.
