Divorcing, do I need to do a quit claim on both homes?

when we got married husband already had house in his name. according to the warranty deed his house is in his mother's name and she did quit deed to him (my name is not on any papers or deeds). his mother died last year. we have been separated for 2 years, i now have a house in my name and my son's name (husband name not on any papers or deeds). as i am writing my own divorce i want to protect both of us from any property worries now or in future. he has not done any improvements to his home and facing foreclosure, whereas, my home is 2 yrs old and all payments paid on time. i want nothing from him, except divorce, but don't want him to take anything from me. do we need quit claim deed on both homes?
