If they have not paid rent, then serve a 3 day notice to pay or quit. Also at the same time, serve a 30 Day notice to terminate tenancy, assuming there is no written lease. If there is a written lease and if it expired, then provide notice to terminate per the terms of the lease. At the same time hire an attorney so that this is all performed properly and timely.
