Home owners insurance canceled on ex husbands claim of frivious lawsuits.

I do not have all the information necessary to be more helpful. However, some states like Florida prevent Insurance Companies from cancelling or non-renewing insurance policies for lawsuits or claims made arising from a natural disaster. For example, many states in the South, and most recently, Texas, have been slammed by hurricanes and tropical storms. Please check with a lawyer in your state and determine what was the basis for the homeowner's insurance claims. An additional idea would be to contact either the Department of Insurance or the Department of Financial Services and see if this is a pattern by the Insurance Company that cancelled your friend's homeowners insurance.
