A Delaware immediate notice to quit is used to notify a tenant that they caused or threatened to cause irreparable harm to a person or property. The landlord can choose to terminate the lease and file an action for summary possession or bill the tenant for the costs of repairing damages, or both. Upon service of this notice to quit, the tenant must vacate the premises and/or pay for damages immediately. This notice also applies to tenants who have been convicted of a class A misdemeanor or felony which caused or threatened to cause irreparable harm to any person or property.
