Constructive trust: Trust imposed by a court in certain circumstances, regardless of the intention of the parties involved (such as where a trustee has improperly profited from his position).

Contempt: Deliberate disregard of a court order.

Contract: Agreement between two or more persons which obliges each party to do (or refrain from doing) a certain thing. A valid contract requires an offer, acceptance of that offer and consideration.

Contract law: Contract law is the basis of all commercial dealings. The terms of a contract may be express or implied. Express provisions may be varied by statute. Unfair contract terms are now excluded by legislation, and, in areas such as employment and the sale of goods, the law imports a wide range of implied terms into new and existing contracts.

Contributory negligence: Negligence which is not the primary cause of a tort, but which combined with the act or omission of another person to cause the damage. In the case of a car crash, for example, an injured driver who was not wearing a seat belt may be found contributorily negligent for his injuries.
