Yes. CCJ and IVA information is readily available via public records. In the event of a claim, especially a large claim or a series of smaller claims; an insurer will look very carefully at financial histories before paying out the claim. If the fact that there is a CCJ or IVA in the household is discovered and you didn’t disclose it if you were asked when you purchased the policy, the claim may not be paid out and it’s likely that your policy will be cancelled at the same time.
