An offer must be specific, complete, capable of acceptance and intention to bound. The acceptance from the offeree must be equally clear, unequivocal and in response to the offer.Offer and acceptance are the fundamental building blocks of contract law, establishing a clear and mutual agreement between both parties. Acceptance represents the meeting of the minds of the parties to the contract - both agree to exchange something for the other (payment, services, goods, etc.). An offer must be "capable of acceptance". This is a reference to legal certainty of what exactly is being offered. It requires an offer, acceptance, consideration (something of value exchanged between the parties), and an intention to create legal relations.
