After my father's death in 2000, we set up a life estate for my mother's home and filed a quit claim on the property in my sister and my names. My sister married in 2001 and live in the home with my mother. Recently my sister and her husband have been having marital problems. In the event of a divorce would my sister's husband have a claim on part of the house. Can we changed the quit claim deed and take off my sister's name so that he wouldn't? Would this start the 3-year period that the state of Minnesota could consider this as my mother's asset (and have to be used as payment for medical care)?
Thank you for any information.
