My question involves landlord-tenant law in the State of: California
Oh boy. My 80yr old father-in-law and his wife have just created and signed an agreement to let a neighbor move his camper trailer onto their property, rent free... for as long as he wants. My wife is freaking out. To summarize the agreement, its a handwritten note signed by Father-in-law, his wife, and the would be tenant. The tenant is a 55 year old neighbor that is losing his house. My in-laws are nice people, so they offered to let him move his trailer on, make improvements, at no cost to them... (pad, septic, etc.). He is a contractor and claims his friends will do all the work for trade. The agreement explicitly states he can stay as long as he likes until the house is sold, then he gets 60 days to move out. No rent, must leave improvements behind with no compensation. It also states that any work he does for them will be compensated for appropriately... I'm not sure why they put that in explicitly...
So other than the basic fears..., like him taking advantage of them as they get older yet, or getting them to sign things without them knowing what it means, or doing work on their house and saying its free of charge, only to ask for money when my wife eventually inherits the property, and the work he does will probably not be permitted. It is out in the country, so doubt anyone will care.... so other than these, are there other things we should be worried about legally? Is this agreement binding? Could he still claim he is owed for improvements? Could he squat there long after the property sells and his 60 days are up, and we have to consider him protected under renter's rights? Even if he is not paying any rent?
Anything else and any advice appreciated. This is just one screwy situation.
Thanks.
