Unjust enrichment is considered one source of obligations, which stands in contrast to harmful acts as another source of obligation in the Jordanian Civil Code (JCC). The Unjust Enrichment Rule has developed historically from Roman law, through Islamic jurisprudence, then French law and jurisprudence to modern laws, such as that in Egypt influenced by French law. All these laws have recognised the Unjust Enrichment Rule as an independent source of obligation. Although the JCC was influenced by Islamic jurisprudence, Arab laws, such as the Egyptian Civil Code, and foreign-influenced Arab laws, its features distinguish it from other laws, either in terms of naming the source or the details related to its legal provisions. JCC’s special features need to be highlighted, defined and evaluated for comparison with other laws, i.e., proving beneficial when enacting a new JCC or defining it as unique rather than a copy of other precedent Arab laws.

不当得利被视为义务的一种来源，这与作为约旦民法典 ( JCC ) 中另一种义务来源的有害行为形成对比。不当得利规则在历史上是从罗马法发展而来的，经过伊斯兰法学，然后是法国法律和法学，再到现代法律，例如受法国法律影响的埃及法。所有这些法律都承认不当得利规则是独立的义务来源。尽管JCC受到伊斯兰法理学、阿拉伯法律（如埃及民法典）和受外国影响的阿拉伯法律的影响，但它的特点是区别于其他法律，无论是在命名来源方面还是在与其法律条款相关的细节方面。联谊会需要突出、定义和评估其特点，以便与其他法律进行比较，即在颁布新的JCC或将其定义为独一无二的而不是其他先例阿拉伯法律的副本时证明是有益的。
