Indonesian Civil Law is an application that discusses all the basic laws that regulate the civil interests of individuals with one another in family relationships and in social interactions in society.

Civil law itself is a colonial law which was originally rooted in BW (Burgerlijk Wetboek) as a result of the work of Dutch legal experts. Then on the orders of the King of the Netherlands, the BW was brought and enforced in the Dutch East Indies.

The Civil Law imposed by the Dutch on the Indonesian people underwent adoption and a very long history.
At that time, the Indonesian people were still familiar with customary law and religious law. Then based on the principle of concordance, it is desirable to have legal regulations in the Netherlands for Europeans in the Dutch East Indies. This legal diversity stems from the provisions of Article 165 IS, which divides the population of the Dutch East Indies into three groups, namely: European, Bumiputera, and Foreign Easterners. After Indonesia's independence, based on Article 2 of the Transitional Rules of the 1945 Constitution, the Civil Code of the Dutch East Indies was still declared valid before being replaced by a new law.
