My family and I have been living in my husband's grandmothers house for 15 years... we moved in to take care of her when her only daughter would not. The homestead is in my mother and father in law's name since before the grandmother died. We have been paying upkeep, insurance, utilities, taxes, repairs, etc. for 14 of these 15 years. My in=laws now decide they want to evict their only son... do we have any rights?
