My husband passed away but only his name is on rental mortgages

[Tiffany Bishop]

This is probably a unique situation, but I'm hoping someone has experience or knowledge.  My late husband and I own three rental properties.  He passed away unexpectedly about a year and a half ago.  The titles of the three properties are all in the name of our trust, but the mortgages were solely in his name.  I haven't done anything about that for the past year+ for multiple reasons, I've just continued to pay them.  However, I'm thinking it's time to do something about them.  I called the lender and no one that I could get a hold of knew anything or would tell me anything about what my options are.  I was just told to send a lot of different documents via snail mail to their corporate offices.  Does anyone know if I have to refinance them under my name? Will I need to pay them off?  Can I just transfer them to my name?  I really have no idea what this will look like.
