The law of obligations is a part of the civil law. It concerns obligations. What do we understand under an obligation? This is the result of a unilateral or two-sided legal act or of a factual act (such as an unlawful act) between two persons. These persons can be both natural and legal persons. The traditional law of obligations is governed by the Civil Code in the Netherlands and Belgium. This concerns an obligation arising from the law, an obligation arising from an agreement or a natural obligation.
