When can an offeror NOT revoke an offer?

An offeror cannot revoke an offer once it has been accepted and that acceptance has been effectively communicated to the offeror. This is a fundamental principle in contract law, where the acceptance of an offer creates a binding agreement between the parties involved. Once acceptance is communicated, the offer transforms into a mutual agreement, and the offeror is legally obliged to uphold the terms of that offer.

Prior to acceptance, the offeror retains the right to revoke the offer. The other scenarios, such as a counteroffer being made or during negotiations, do not impede the ability of the offeror to revoke the original offer until acceptance occurs. Thus, acknowledging the point at which acceptance is communicated is crucial in defining the moment an offer becomes irrevocable.
