Three major reasons a contract becomes void (invalid from the start) are illegal purpose (e.g., a contract to commit a crime), lack of capacity (one party is a minor, mentally incapacitated, or intoxicated), and lack of mutual assent/fraud/duress (e.g., one party was forced, tricked, or there was a fundamental misunderstanding between parties).

A text message can count as legal notice, but it's risky; it's only valid if the contract allows it or if you can prove the recipient clearly received, understood, and acknowledged it, making traditional methods (certified mail, email with consent) often safer for important matters like leases or official business. Courts prefer texts when the parties usually communicate this way or when there's a response, but lack of clear proof of receipt or jurisdiction-specific laws can invalidate it.
