Before making a possession claim on the ground in section 157, the landlord must give the contract-holder a possession notice specifying that ground.

The landlord may make a possession claim in reliance on a breach of section 55 (anti-social behaviour and other prohibited conduct) on or after the day on which the landlord gives the contract-holder a possession notice specifying a breach of that section.

The landlord may not make a possession claim in reliance on a breach of any other term of the contract before the end of the period of one month starting with the day on which the landlord gives the contract-holder a possession notice specifying a breach of that term.

In either case, the landlord may not make a possession claim after the end of the period of six months starting with the day on which the landlord gives the contract-holder the possession notice.

This section is a fundamental provision which is incorporated as a term of all occupation contracts.
