Since contract law is at the heart of most business relationships, it is one of the three or four most important legal issues and can lead to differences in circumstances and complexity. The existence of a contract requires the recognition of the following actual elements: (a) an offer; b) an acceptance of this offer leading to a meeting of spirits; (c) a promise of execution; (d) a valuable consideration (which may be, in any form, a commitment or payment); (e) a period or event during which the performance must be completed (execution of obligations); (f) performance conditions, including the fulfilment of promises; g) performance. A unilateral contract is a contract by which there is a commitment to pay or provide another consideration in exchange for the actual benefit.
