cure or quit

Definition from Nolo’s Plain-English Law Dictionary

The type of written notice given to a tenant by a landlord, telling the tenant that he or she must cease a certain behavior within a certain number of days, or move out. If the tenant does neither, the landlord may proceed with an eviction lawsuit in most situations. Common reasons for a cure or quit notice are having a pet in violation of a no-pets lease clause, causing a nuisance or disturbance, and having an unauthorized occupant in the rental.
