Quit claim deed

there is a house abandoned in my neighborhood for 4 years now with city liens attached to it. i researched and found the owner who is willing to quit claim the property to me. property owner's spouse died four years ago leaving her the sole owner of the property and bank notes. even though she still owns the property the bank is processing foreclosure papers. she has not been served or anything. can she transfer her interest in the property by quit claim deed in order for me to conduct negotiations with the bank for ownership? she lives in another state from where the property is and has no further interest in this property. the property has been badly vandalized by squatters. it is in florida.
