What is the status of a contract when a seller accepts an offer knowing that the buyer has died?

When a seller accepts an offer and is aware that the buyer has died, the correct understanding is that the offer is terminated due to the buyer’s death. In contract law, the death of the offeror essentially nullifies the offer because the offer is a personal proposal that cannot be assigned or enforced after the death of the person who made it. The seller's acceptance of the offer cannot create a valid contract if the buyer is deceased, as the buyer can no longer fulfill the obligations of the contract. Therefore, the acceptance by the seller becomes ineffective, and there is no binding agreement between the parties.
