Civil law is one of the laws that regulates inheritance in Indonesia. Fighting over inheritance occurs a lot and is a case that is often handled in courts. Control of inherited assets by people other than the legal heirs is also something that is not uncommon, considering that most of the perpetrators and victims are related, the rules governing heir groups in civil law need to be paid more attention in handling inheritance cases. In writing this thesis, the author used the topic of inheritance law cases originating from court decision number 201/Pdt.G/2019/PN Sby. The problem formulation used concerns the implementation of civil law rules used by the Panel of Judges in considering the case. The aim of writing this thesis is to provide more insight into the proper division of inheritance and the implementation of existing civil law in Indonesia in handling inheritance cases. The research methodology used is normative legal research with primary data originating from the Civil Code. Constitution of 1945, Law Number 1 of 1974, and Constitutional Court Decision Number 69/PUU-XIII/2015. The topic that the author takes is the implementation of existing regulations in civil law in the distribution of inheritance which occurs after the inheritance is opened or after the Benefactor is declared dead. However, remembering that inheritance division is the division of the inheritance of the heir, it is not uncommon to find heirs or the heir's family who want the inheritance and use inappropriate methods to obtain it. Sometimes, if the method used is against the law but only causes harm, then the perpetrator or defendant will be punished because he has committed an unlawful act. Unlawful Acts are acts that are often found in society related to actions carried out by them to fulfill their interests by violating the law, but which also cause losses to the victim, but the losses can only be replaced if there is concrete evidence.
