What is the mailbox rule?

The mailbox rule, also known as the "postal rule," is a legal principle that states that once a letter is properly addressed, stamped, and deposited in the mail, it is considered to be legally delivered and accepted by the recipient. This rule applies to contracts and legal documents that are being sent via mail.

The mailbox rule is based on the idea that once a letter is mailed, the sender no longer has control over its delivery, so it should be considered delivered at the moment it is sent. This means that the acceptance of a contract or offer sent via mail is legally binding as soon as it is placed in the mailbox.

It is important to note that the mailbox rule may not apply in all situations, such as when the parties involved have agreed to a different method of communication or when the letter is lost or delayed in the mail. Additionally, some jurisdictions may have variations or exceptions to the mailbox rule, so it is always best to consult with a legal professional for advice on specific cases.
