I live in the state of California. My sister has been living with parents,she payed bills. Parents sold the house and gives verbal warnings that sister has until the end of the month to leave. Middle of month comes, new house owners demands ownership of property and of my sister's and says she has to get out. Is my sister considered a tenant and does she have renters rights? Also new house owner starts moving in her stuff and harassing my sister too and saying she has to leave. We call police, and police arrive after new house owner is absent. Officer explains that my sister had to be properly evicted and must have legal paper work stating she has to leave, and if harassment escalates to call 911. New house owner comes back after officer leaves and situation escalates and she has changed locks to lock my sister out, we called 911. Two officer arrive and tell us my sister has no rights because there is new home owner and we have to leave. I explained to him a previous officer acknowledged she had renters rights, he said that officer was wrong in everything he said. I asked to see legal documents and he declines and says those documents are private to new home owner.
