I signed a rent stabilized lease with my roommate (as co-tenants) 4 years ago. This year, when we were sent a renewal (for Aug 1) we discussed that my roommate would leave the apartment at some time after the lease period, and would not resign the lease. She provided the landlord with a notarized letter relinquishing her claim to the apartment and security deposit, and I signed the renewal lease alone. I am now the sole tenant on the lease, according to our rent slips.
I understand that she is having difficulty finding an acceptable new apartment, and does not want to leave. In August, following the expiration of our co-tenancy, I had suggested that she move out by the end of October, which she expressed was too soon. She did not provide an alternative date. It is now October 5, and she refuses to leave or provide a date for her departure. She refuses to speak to me or share any plans. We have an increasingly difficult relationship, and I do not wish to live together any more.
Am I within my rights to initiate a holdover proceeding at the end of October? What are my options? Any advice? It's a bit of a maddening situation.
