The Civil Code of Indonesia (Dutch: Burgerlijk Wetboek van Indonesië, BW), commonly known in Indonesian as Kitab Undang-Undang Hukum Perdata (lit.

On 1 January 1811, the Netherlands was annexed by the French Empire and the Napoleonic Code was adopted in unmodified form.

Article 100 of the 1814 Constitution refers to a codification based on Dutch law in which various proposals were made between 1816 and 1830.

Finally in 1830 a new code was enacted by Parliament which is a mix of influences, mainly from French and Roman-Dutch law.

Burgerlijk Wetboek was then modified by the Dutch East Indies government to apply exclusively to Europeans and Foreign Orientals, yet based on Article 2 of the transitional provisions of the 1945 Indonesian Constitution, it states that: "All State Bodies and Regulations that existed until the founding of the Republic of Indonesia on August 17, 1945 shall remain in force, as long as new ones have not been enacted according to the Constitution".
