Nathan entered a contract while he was seventeen. If, upon reaching the age of majority, he has not avoided the contract and promises to perform those contractual obligations, new consideration is required for the contract to be enforceable.

Upon reaching the age of majority, if Nathan affirms the contract either by action (such as continuing to abide by the contract's terms) or explicitly states his intention to fulfill the contractual obligations, the contract becomes enforceable without the need for new consideration. This is because his affirmation or ratification of the contract upon reaching the age of majority is treated as acceptance of the contract's terms as an adult.
