mother lost home in tornado mortgage company doesnt have title to land/home where to get title?

mother lost home in tornado mortgage company doesnt have title to land/home where to get title?...My mother lost her home in a tornado a few weeks ago. I'm trying to get all the documents required for the insurance company to complete her claim. The mortgage company is not assisting at all. I had always thought when a home is destroyed it was the responsiblity of the mortgage and insurance company to talk directly to one another. Anyhow, the insurance company needs a copy of the land and home title. I have spoken with the mortgage company on 4 occasions but they have not sent the title. I have a feeling they have lost them. It is a mobile home and I don't know if that makes it any different than a regular house. What can I do or where can I go to get a copy of the titles? I need these titles in order to get the insurance check to pay off the mortgage. And I need it fast. My mom has been homeless living in a hotel room for two weeks now. It's sad she has lost everything. Please send me any guidance you have.
Thank you.
