Final answer:
If a minor signs a contract to buy real estate, the contract is usually considered voidable, giving the minor the choice to affirm or reject the contract upon reaching adulthood.
Step-by-step explanation:
When a minor signs a contract to buy real estate, the resulting contract is generally considered to be voidable at the option of the minor. This means that the minor has the choice to either affirm or reject the contract upon reaching the age of majority or within a reasonable time afterward. Contracts entered into by minors are voidable because minors are considered to lack the legal capacity to enter into a binding agreement due to their age. However, the contract remains valid until the minor takes action to void it.
