Capacity to contract refers to a party’s legal ability to enter into a binding agreement. Certain individuals are restricted from full contractual liability due to age, mental condition, or legal status. Where capacity is lacking, contracts may be void, voidable, or enforceable only in limited circumstances.
Capacity issues most commonly arise with minors, who are generally bound only by contracts for necessaries and beneficial contracts of service. In Nash v Inman, a minor was not required to pay for expensive clothing deemed unnecessary for his status, showing how the courts protect young persons from unfair obligations. Mental incapacity and intoxication can also affect enforceability if the other party knew or ought to have known of the incapacity. Companies may face capacity questions where actions fall outside their objects, though modern law has reduced this issue significantly. The key exam focus is balancing protection of vulnerable parties with the need for commercial certainty.
