There is an acceleration clause is most deed of trusts, that is, his mortgage document that calls for a full payment of a mortgage if the title is transferred in this manner, but people do it all the time and accept that is the mortgagee/lender ever exercises this clause then you'll just have to refinance the property and since you were paying the mortgage and have proof, you should have no difficulty in refinancing the property.

Now there is something called due on sale clause and this can be exercised if title is changed out of your name.
