Contract Law · defense
Capacity in contract law refers to the legal ability of a person to enter into a binding contract. A party must have the mental competence and legal authority to understand the nature and consequences of the contract they are entering into.
A party must possess the mental capacity to understand the contract's nature and implications at the time of agreement.
What to prove: It must be shown that the individual lacked the ability to comprehend basic contract concepts or to appreciate the consequences of the agreement.
The individual must be of legal age, usually 18 years old, to enter into a contract unless specific exceptions apply.
What to prove: It must be established that the person is not a minor or, if they are, that the minor has not disaffirmed the contract per applicable laws.
The person must not be mentally incapacitated or under the influence of substances in a manner that impairs judgment.
What to prove: Evidence must demonstrate that at the time of contract formation, the individual was unable to understand the nature of the transaction due to mental illness, intoxication, or similar conditions.
The burden of proof generally lies with the party challenging the contract's validity, who must demonstrate by a preponderance of the evidence that the other party lacked capacity.
In exams, focus on identifying scenarios where a party’s capacity is questioned and analyze the evidence supporting or refuting capacity.
