What aspect of parties does 'capacity' address in contract law?

Capacity in contract law specifically addresses the legal ability of the parties to enter into a contract. This concept ensures that individuals or entities involved in a contract possess the requisite qualities to understand the nature and consequences of their agreement. For instance, parties must be of a certain age, typically at least 18 years old, and they must also be of sound mind. This means they should not be impaired by mental incapacity or intoxication, which could affect their understanding and ability to consent.

While financial status, negotiation skills, and experience in business transactions can influence the effectiveness and execution of a contract, they do not directly relate to the legal standing or ability to form a binding agreement. Therefore, understanding capacity is crucial in contract law to determine whether an agreement is enforceable and to protect parties who may not legally have the ability to enter into contracts.
