Ilyce R. Glink column also has this question;

Q: I signed a quitclaim when I purchased my first new home because I am partnered with a woman. I was told this was a way that she could have something to hold on to in case we were ever to break up. I just want to know if this means I no longer have ownership in our property.

I gotta bad feeling about that question. It sounds like she could kick him out anytime but he would still be liable for the payments. The worst of both worlds.
