Which situation would make a real estate contract voidable?

A real estate contract is considered voidable when one party has the right to affirm or reject the contract due to certain circumstances that affect their ability to consent freely and knowledgeably. In the context of being signed by a minor, the law gives minors the ability to disaffirm contracts, which means a contract signed by a minor can indeed be voidable.

When a minor signs a contract, they are not considered to have the legal capacity to enter into a binding agreement, which is why the contract is voidable at the minor's discretion until they reach the age of majority. This right is rooted in the protection of minors from legal obligations they may not fully understand or appreciate.

The other scenarios, while they can lead to complications or the potential for disputes, do not directly address the conditions under which a contract becomes voidable in the same definitive manner as the situation involving a minor. A contract not being in writing may affect enforceability but doesn’t automatically render it voidable. Similarly, while duress and misrepresentation relate to consent, they do not create the same clear right to void the contract outright as is provided to minors.
