I allowed someone to store their property at my house. I keep asking her to get her property but she has not. She does not keep in contact with me. Now I am planning on moving, can I sell her propery, is it considered abandoned. It has been at my house for almost 2 years

A great deal depends on what the property is. WA laws vary depending on the actual type of property. Revised Code of Washington - RCW Title 63 Personal Property - Section 63.29.020 Property presumed abandoned -- General rule -- Exceptions - Washington Attorney Resources - Washington Laws
