Help,, Question Home Policy is Running Out

I have a problem, my parents died without a will, no estate planning, there are no signers on anything, just my Dads name on the deed. The insurance policy on the house they owned is due. My younger brother has lived in the house his whole life, mom and dad wanted him to have the house, which is fine by me, my question is can he be added to the home's insurance policy, I'm at a loss here and time is running out, I don't want the policy to lapse, and the house to be covered, the policy is thru Farmers in California
