NCA Contracts common mistakes

NCA Contracts · Understand the traps and how to avoid them.

Mistake 1

Treating every agreement as a binding contract without separately establishing offer, acceptance, consideration and intention, so a problem question on a domestic social arrangement is answered as if it were a commercial bargain.

Candidates learn the four elements as a checklist and then apply them mechanically to every fact pattern, without noticing that the question is testing whether the presumption of contractual intention has been rebutted.

What to do instead

Before writing, classify the context (commercial, domestic/social, employment, public body) and state which presumption applies and who bears the burden of rebutting it. Then work through each element only as far as the facts require, flagging the contested element as the analytical core of the answer.

Mistake 2

Analysing an invitation to treat, a counter-offer and a request for information as though they were interchangeable, and concluding that a contract formed at the wrong moment.

The vocabulary is learned as a list of labels rather than as a sequence of events, so candidates cannot track how the offeror/offeree roles reverse when a counter-offer is made.

What to do instead

Draw a short timeline of communications in the margin, labelling each as invitation, offer, counter-offer, inquiry or acceptance. Apply the mirror-image rule to each response, and state expressly whose offer is live at the moment of acceptance and whether the original offer was destroyed.

Mistake 3

Confusing past consideration, existing duties and part-payment of a debt, and concluding that any detriment suffered by the promisee is sufficient consideration.

Candidates remember that consideration must be sufficient but need not be adequate and then treat any inconvenience as satisfying the requirement, missing the rules on pre-existing obligations and the practical-benefit exception.

What to do instead

Test consideration in three steps: was the act done before the promise (past consideration, generally not good); was it already owed to the promisor or a third party (existing duty, with the practical-benefit gloss); and is it a lesser sum owed (part payment, generally no discharge without fresh consideration). Cite the governing principle for whichever step is decisive.

Mistake 4

Ignoring the formal requirements point in a question involving land, guarantees or consumer credit, and advising on breach and remedies as if the contract were fully enforceable.

Candidates focus on the dramatic facts (the breach, the loss) and treat formality as a technicality, forgetting that a defective form can make the contract unenforceable regardless of the merits.

What to do instead

Screen every question for subject matter first: is it a disposition of an interest in land, a guarantee, or a regulated consumer contract? If so, state the formality requirement, whether it is satisfied, and the consequence of non-compliance, including any part-performance or collateral-contract route, before moving to remedies.

Mistake 5

Treating all pre-contractual statements as terms, or all of them as representations, without applying the guidance factors on importance, timing, relative knowledge and reduction to writing.

Candidates want a single label quickly so they can move on to remedies, and they do not distinguish the consequences of each classification (damages for breach versus rescission and damages for misrepresentation).

What to do instead

For each statement, work through the indicators: was it vital to the transaction, how close to formation was it made, did one party have special knowledge, was it later written down, and did the maker invite verification? State the classification, then state the distinct remedial consequences that follow from it.

Mistake 6

Applying the parol evidence rule rigidly to exclude all extrinsic material, and failing to use interpretation principles, implied terms and the effect of exemption clauses on the surrounding context.

Candidates memorise the rule as an absolute prohibition and do not realise that modern interpretation permits consideration of background, commercial purpose and the factual matrix, and that exemption clauses are construed strictly against the party relying on them.

What to do instead

When a clause's meaning is disputed, set out the interpretive approach (natural meaning in context, commercial sense, factual matrix) before reaching a conclusion. Separately address incorporation, construction and any statutory controls on exclusion clauses, and note that implied terms are a distinct route from interpretation.

Mistake 7

Describing misrepresentation, mistake, duress and undue influence as overlapping 'unfairness' doctrines and applying one label to facts that properly support another.

The vitiating factors share a family resemblance (the victim wants out), so candidates collapse them into a general fairness argument and lose the marks for the distinct elements and remedies.

What to do instead

Build a decision tree: was there an untrue statement of fact inducing the contract (misrepresentation, with type determining remedy); was there a fundamental error about subject matter, identity or terms (mistake, with common, mutual and unilateral categories); was there illegitimate pressure (duress) or a relationship of trust abused (undue influence)? Address each plausible head in turn and explain why the others fail.

Mistake 8

Treating every breach as entitling the innocent party to terminate, without distinguishing conditions, warranties and intermediate terms or assessing whether the breach deprived the innocent party of substantially the whole benefit.

Candidates conflate repudiatory breach with any breach, and do not connect the classification of terms to the right to terminate, affirm or claim damages.

What to do instead

Classify the term first, then assess the consequences of its breach. State whether the breach is repudiatory, whether the innocent party may elect to terminate or affirm, the effect of affirmation, and the separate entitlement to damages. Note the effect of an express termination clause where one exists.

Mistake 9

Awarding expectation damages without checking remoteness, mitigation and contributory fault, and omitting restitution or specific performance where damages are inadequate.

Candidates equate the expectation measure with the whole answer and forget that recoverability is a filter applied after the measure is chosen.

What to do instead

Structure the remedies answer in stages: identify the measure (expectation, reliance or restitution), apply the remoteness test, address mitigation and any contributory conduct, then consider equitable remedies and their discretionary bars. For liquidated damages, separately test whether the clause is a genuine pre-estimate or a penalty.

Mistake 10

Answering problem questions with a narrative of the facts and a conclusion, without naming the legal test or authority for each step.

Candidates run out of time and write the story back to the examiner, believing that a confident conclusion earns the marks that are actually awarded for the reasoning.

What to do instead

Use an issue, rule, application, conclusion structure for each distinct issue, keep the facts to the ones that trigger a rule, and cite the principle or case name for every proposition. Finish with a short conclusion that answers the question actually asked and flags any unresolved contingency.
