Offer

Offer and acceptance analysis is a traditional approach in contract law used to determine whether an agreement exists between two parties. As a contract is an agreement, an offer is an indication by one person (the "offeror") to another (the "offeree") of the offeror's willingness to enter into a contract on certain terms without further negotiations. A contract is said to come into existence when acceptance of an offer (agreement to the terms in it) has been communicated to the offeror by the offeree.
From Wikipedia, the offer and acceptance formula, developed in the 19th century, identifies a moment of formation when the parties are of one mind. This classical approach to contract formation has been weakened by developments in the law of estoppel, misleading conduct, misrepresentation and unjust enrichment.
Offer as "an expression of willingness to contract on certain terms, made with the intention that it shall become binding as soon as it is accepted by the person to whom it is addressed", the "offeree". An offer is a statement of the terms on which the offeror is willing to be bound.
Whether two parties have an agreement or a valid offer is an issue which is determined by the court using the Objective test (Smith v. Hughes). Therefore the "intention" referred to in the definition is objectively judged by the courts. In the English case of Smith v. Hughes the court emphasised that the important thing is not a party's real intentions but how a reasonable person would view the situation. This is due mainly to common sense as each party would not wish to breach his side of the contract if it would make him or her culpable to damages, it would especially be contrary to the principle of certainty and clarity in commercial contract and the topic of mistake and how it affects the contract. As a minimum requirement the conditions for an offer should include at least the following 4 conditions: Delivery date, price, terms of payment that includes the date of payment and detail description of the item on offer including a fair description of the condition or type of service. Without one of the minimum requirements of condition an offer of sale is not seen as a legal offer but rather seen as an advertisement.
