A mortgage cannot be removed ("stripped") from a parcel of real property in a Chapter 7 Bankruptcy, but that may potentially occur in a Chapter 13 Bankruptcy if you meet the requisite criteria. 

Specifically, while you cannot strip a first (1st) mortgage, you might be able to strip a second (2nd) mortgage.  However, that would necessitate that the parcel be your primary residence, and that the balance due on the first (1st) mortgage be in excess of the home's reasonable fair market value.
