The three (3) day notice to pay or quit that you received concerning your rental is a statutory process where the landord is giving you the option to pay the dollar amount demanded to stay in the rental or if not, you are being advised that your lease will be at an end.If you do not pay the demanded amount in the designated time period, you will most likely be served with an unlawful detainer action. If the lease is deemed at an end, the landlord could still sue you for the balance of the time remaining on the lease after you are evicted or choose to leave the premises. I suggest that you consult with a landlord attorney about your situation.Good luck.
