My question involves personal property located in the State of: California
so my story is we help our son in law store property from his parents business at a our property for the purpose of clearing out a shop after it was sold. him and his mother had a disagreement on how the shop property was to be sold. two years later after she threatened to sue him he sent her a notice to pic up property after a few months she came a picked up cars but left the to other shop property. she hasn't come back to get the property need it off our property because it is a I sore and health hazard. she threaten to sue again but she is the one who isn't picking up her property. she lives in Arizona also. first can she sue and second can we throw the property away or salvage it. we were told that she gave up her rights when she gave the keys to her son.
