Each contracting party must be a “competent person” who is legitimate. The parties may be natural persons (“individuals”) or legal persons (“limited communities”). An agreement is reached when an “offer” is accepted. The parties must intend to be legally bound; and, to be valid, the agreement must have both an appropriate “form” and a legitimate purpose. In England (and in jurisdictions that apply English contractual principles), parties must also exchange “considerations” to create “reciprocity of engagement,” as in simpkins v Country.  Appel appel agreements Also known as call contracts. See standing ordinances. When a contract is written and someone signs it, the signatory is generally bound by its terms, whether he has actually read it , provided that the document is of a contractual nature.  However, affirmative defences, such as coercion or scruples, may allow the signatory to evade the obligation.

Client claims against investment dealers are almost always settled by contractual arbitration clauses, as securities dealers are required to settle disputes with their clients, in accordance with the terms of their affiliation with self-regulatory bodies such as the Financial Industry Regulatory Authority (formerly NASD) or the NYSE.

The terms of the contract are defined as unnominated terms, warranties or conditions. The conditions may be implied due to the actual circumstances or the conduct of the parties. In BP Refinery (Westernport) Pty Ltd v Shire of Hastings, the British Privilege Council proposed a five-step test, citing Australia, to identify situations in which the facts of a case could involve conditions. The classic tests were the “Business Efficacy Test” and the “Officious Bystander Test”. In the context of the “Business Efficacy Test”, first proposed in The Moorcock , the minimum conditions necessary to give commercial efficiency to the contract are implicit. According to the test officious bystander (referred to in Southern Foundries (1926) Ltd v Shirlaw , but in fact originated from Reigate v. Union Manufacturing Co (Ramsbottom) Ltd , a term can only be implied if an “officious bystander” listening to the contract negotiations proposes that the notion that the parties would immediately agree be included. The difference between these tests is debatable. A contract is often proven in writing or by a document, the general rule is that a person who signs a contractual document is bound by the conditions of this document, this rule is called rule in L`Estrange v Graucob.  This rule was approved by the High Court of Australia in Toll (FGCT) Pty Ltd v Alphapharm Pty Ltd.  However, a valid contract may be concluded (with a few exceptions) orally or even by conduct.
