Which of the following is not required to prove legal capacity in a contract?

In a legal context, proving legal capacity typically involves demonstrating that a party to a contract meets certain criteria that allow them to enter into a binding agreement. Among these criteria, being of the age of majority, having a sound mind, and being free from duress are crucial elements.

The age of majority refers to the legal threshold at which an individual is recognized as an adult and can make binding contracts, typically 18 years old in Georgia. A sound mind indicates that the individual has the mental competence necessary to understand the nature and consequences of the agreement they are entering into. Being free from duress means that the individual is entering the contract voluntarily and is not being coerced or threatened.

However, being a citizen of Georgia is not a requirement to establish legal capacity in a contract. Legal capacity is focused on an individual’s age, mental state, and the circumstances of consent, rather than their citizenship status. Therefore, the correct answer points out that citizenship does not impact one's ability to legally enter into contracts, making it the option that is not required for proving legal capacity.
