My question involves landlord-tenant law in the State of: Oregon, Multnomah County
I had an agreement with a prospective roommate to move in on the first of May, 2016, under the verbal agreement they would pass their rental application with the landlord. They moved in on May 1, yet delayed turning in the application until May 7. It was denied on May 11. Their possessions are still in my apartment, they have a key, yet they have not been here in several days.
There are no written agreements between them and myself, nor them and the landlord--except for when the landlord provided them a letter asking them to leave (I don't believe it was official or legally-worded).
Are they legally considered a tenant? What are the legal requirements for me to have them leave? The landlord is also unaware of what steps are needed. Thank you.
