Accepting – in the Common Law system, this term defines one of the three requisites of a valid agreement (the other two are the offer and the consideration). There is a legal rule that a contract is a legally binding agreement between two or more parties, which starts with an offer sent from one person to another. But which offer does not become a valid agreement until the opposite party (the beneficiary of the offer) shows their consent to accept the offer. The moment of accepting the offer is the moment from which a contract between two opposite parties is considered validly concluded, and not before. Acceptance is not always needed to be direct and can, in certain circumstances, be implied by conduct (see acquiescence below). In most jurisdictions, a useful acceptance, easiest to be proved is the one executed in writing (usually via signing a mutual agreement). See also http://en.wikipedia.org/wiki/Acceptance .
