188.Paragraph 3 makes provision for calculating the probation period applying to prohibited conduct standard contracts. A probation period is the period for which an occupation contract remains a periodic standard contract as a result of a court order under section 116. The period is 12 months from the occupation date of the prohibited conduct standard contract, as set out in the order. This is subject to a landlord being able to apply for an extension of the probation period to 18 months under paragraph 4. The landlord may also end the probation period early by giving a notice under paragraph 3(2). The paragraph also makes provision dealing with situations where possession notices are given by the landlord but possession claims are neither brought nor concluded prior to the expiry of the probation period.
