Final answer:
In a contract involving an adult and an infant, either party can disaffirm the contract.
Step-by-step explanation:
The statement is true. In a contract involving an adult and an infant, either party can disaffirm the contract. An infant refers to a person who is under the age of majority, typically 18 years old. Since infants lack the legal capacity to enter into contracts, they are generally protected by law and can choose to disaffirm the contract at any time.
