The postal rule specifies that acceptance comes into force from the moment the letter of acceptance is posted to the offeror. In Household Fire Insurance Company v. Grant, the defendant made an offer which was accepted by the plaintiff. However, the letter of acceptance posted by the plaintiff to the defendant failed to reach him. The Appellate Court held that the contract was deemed to be concluded the moment the plaintiff posted his acceptance letter, and the defendant was held liable (Household Fire and Carriage Insurance Co v Grant, 1879).
