Law of obligationsThe law of obligations is one branch of private law under the civil law legal system and so-called "mixed" legal systems. It is the body of rules that organizes and regulates the rights and duties arising between individuals. The specific rights and duties are referred to as obligations, and this area of law deals with their creation, effects and extinction. An obligation is a legal bond (vinculum iuris) by which one or more parties (obligants) are bound to act or refrain from acting.
CostIn production, research, retail, and accounting, a cost is the value of money that has been used up to produce something or deliver a service, and hence is not available for use anymore. In business, the cost may be one of acquisition, in which case the amount of money expended to acquire it is counted as cost. In this case, money is the input that is gone in order to acquire the thing. This acquisition cost may be the sum of the cost of production as incurred by the original producer, and further costs of transaction as incurred by the acquirer over and above the price paid to the producer.
Contractual termA contractual term is "any provision forming part of a contract". Each term gives rise to a contractual obligation, the breach of which may give rise to litigation. Not all terms are stated expressly and some terms carry less legal gravity as they are peripheral to the objectives of the contract. The terms of a contract are the essence of a contract, and tell the reader what the contract will do. For instance, the price of a good, the time of its promised delivery and the description of the good will all be terms of the contract.
