My father passed away in 1986 and the house is in my mother’s name. My sister, who married against our wishes, has been claiming the house for the past 6 years and refuses to pay any rent. What legal options do we have to get her out?

Since your father passed away in 1986 and the house is in your mother’s name, she is the legal owner. You can file an eviction suit against your sister as she is a trespasser and has no legal claim to the property. You must establish your mother’s ownership through inheritance documents and prove that your sister is refusing to pay rent.
