Which term describes when an offer is deemed ineffective due to the death of the offeror?

The term that describes when an offer becomes ineffective due to the death of the offeror is referred to as "Death of Offeror." In contract law, an offer is contingent upon the offeror's ability to fulfill the terms and conditions of that offer. Therefore, if the offeror passes away, the offer cannot be accepted because the foundational element of the offer—the intention and ability of the offeror to enter into a contract—no longer exists.

This principle is rooted in the idea that offers are personal in nature; they reflect the willingness of the offeror to enter into a contractual relationship. Once the individual who made the offer is no longer alive, there can be no acceptance of that offer by the offeree.

It's important to differentiate this from other concepts. For instance, revocation of an offer occurs when the offeror voluntarily withdraws the offer before it is accepted. The lapse of offer refers to the expiry of an offer after a certain period, whether or not the offeror dies, and an invalid offer generally means an offer that cannot be accepted for legal reasons but is not directly tied to the death of the offeror.

Thus, the term "Death of Offeror" precisely captures the legal situation where death renders an offer ineffective
