Deceased Father and I joint tenancy survival, Ex wife on deed

[John D Forth]

My father and I bought a home in 1996 joint tenancy right of survival mortgage. We both lived in the home as well as my wife. My wife moved out less than a year later and we divorced in 1997. My father died in 1998. The mortgage is still in my primary name and he as the secondary. I will be needing to refinance soon. A bank representative has said my ex wife's name is somehow still tied to perhaps the deed. There is language and my ex wife's signature in the mortgage paper ,that my father insisted to be included , that she holds no rights to the property. There is also language in our divorce papers that she holds no interest in the home or other marital property.... Will refinancing be a problem for me ?  I married my present wife in 2000 ...Thanks !
