Before an individual can enter into a binding legal agreement known as a contract, he or she must meet the legal contract age.

Minors usually cannot enter into a legally binding agreement such as a contract because they are not old enough to be held accountable for their actions. if such an instance occurs wherein a party of legal contract age enters into a legally binding agreement with one who is not of legal contract age, the latter may void the agreement in the event that the terms and conditions cannot be fulfilled by him or her.
