Before you enter into a contract of general insurance with the insurer you have a duty to disclose to the insurer every matter that you know, or could reasonably be expected to know, is relevant to the insurers decision whether to accept the risk of the insurance and if so on what terms. You have the same duty to disclose those matters to the insurer before you renew, extend, vary or reinstate a contract of general insurance. Your duty does not require disclosure of matters: - that diminish the risk to be undertaken by the insurer - that are common knowledge - that the insurer knows, or in the ordinary course of its business, ought to know - as to which compliance with your duty is waived by the insurer. Non-disclosure - If you fail to comply with your duty of disclosure, the insurer may be entitled to reduce its liability under the contract in respect of a claim or may cancel the contract. If your non disclosure is fraudulent the insurer may also have the option of avoiding the contract from its beginning.
