We have relatives that need to be removed from a residence. The owner (the dad) wants two of his middle aged sons out. They have an agreement with the dad on paper that they will leave by 01/31/2011, however many of us feel this won't work. The document isn't notarized to our knowledge, however the dad has asked for assistance, if needed, from myself and my older brother. The two are our half brothers, and do not work, have no income, except what dad provides to them. Dad is retired, on Social Security and Medicare. The question is: Do they have a legal right to stay in the house?
