W. Va. Code § 33-6A-2: Cancellation for other reasons void.

Any purported cancellation by an insurer of a policy of automobile liability insurance which has been in effect for sixty days and which has been renewed shall be void if the purported cancellation is contrary to section one of this article. For purposes of this article, the transfer of an insured between insurance companies within the same group is not considered a cancellation or nonrenewal of an automobile liability insurance policy if the transfer is based upon any valid underwriting reason involving a substantially increased risk associated with the policy.
