Jurisdiction overview

Brunei is an oil-rich country in East Asia and an absolute monarchy, where the Sultan of Brunei is both head of state and head of government. The country has strong ties with the UK as it was a colony until 1984. Its legal system is therefore based on English common law with an independent judiciary, a body of written common law judgments and statutes, and legislation enacted by the Sultan.

The corporate legal practice in the country is dominated by Abrahams Davidsons & Co and CCW Partnership with the former being focused on corporate and commercial work and the latter focused on construction, real estate and technology. 

As a state composed of a majority of Muslims, Islam has been made the official religion of Brunei Darussalam but there is also concern that the country is shifting towards adopting an Islamic legal framework.

In 2014, the monarch Sultan Hassanal Bolkiah, also one of the wealthiest men in the world, announced his intention to introduce a full shariah system in the nation. Under the new law, tough Islamic punishments are rolled out and critics on social media websites could face prosecution.
