Removing ex wife from title - she was never a borrower

[Daniel Murphy]

Hey all, I have a home in MN and a home in FL. I'm recently divorced and kept the 2 properties.  My understanding is that I will need to refi in order to get my ex off of the properties.  My question is, both of these homes were purchased under my name only because she had no income. So all closing docs, title etc. only have my signature.  I understand joint legal ownership, but that normally seems to apply at selling.  

Are there any thoughts, options or opinions on how to remove her name from the titles without a refi?
