So...friends of mine had a burglary and claimed on their insurance. Their insurance is now up and due for renewal. They are panicking that they forgot to notify the insurance company of an extension they had a couple of years ago in case it voids their claim. Extension was to a different part of their home and not where breakin occurred. I thought I'd ask the wise people of MN if it will void their claim if they now let insurance company know (extension predates burglary). Namechanged as when I show them thread, I don't want them to see other stuff I've posted!
