Final answer:
In Illinois, the age of majority is 18, and upon reaching this age, individuals have a reasonable time to void contracts made as minors, although the specific statutory period may vary and legal consultation is advised.
Step-by-step explanation:
When a minor enters into a contract in Illinois, they may have the right to void the contract upon reaching the age of majority. In Illinois, the age of majority is typically 18 years old. After a person reaches the age of majority and becomes an adult, they generally have a reasonable period to disaffirm contracts they entered into while they were still minors. However, the exact statutory period for disaffirming a contract is not fixed and may depend on the specific circumstances, including the type of contract and state law provisions. It is important for individuals to consult legal counsel to understand their rights and obligations as the period may vary.
