Abstract：As one of the most important principles in insurance law, the doctrine of utmost good faith requires the parties to disclose material facts related to the risk and to abstain from misrepresentation. As time passed by, the doctrine was questioned and challenged by judges, commentators and law reform bodies. In February of 2015, UK Parliament passed the Insurance Act 2015, which introduces the most significant reform to English insurance law for the last 100 years. The purpose of this article is therefore to examine the main changes of the 2015 Act, including the duty of fair presentation and the remedies in failure to disclose. This paper will also examine the relevant Chinese's insurance law and attempt to draw a conclusion as to what we could learn from the 2015 Insurance Act.
