Section 21 inserts new section 5A into the Protection from Eviction Act 1977. Subsections (1) and (2) make clear that any attempts by a landlord to specify the form of writing a notice to quit must take will have no effect.
	Subsection (3) sets out that a notice to quit may be withdrawn before the date on which it takes effect, if agreed in writing by the tenant and landlord.
	Subsection (4) specifies that if the tenancy is a joint tenancy, then all the tenants must agree with the landlord to the withdrawal of a notice to quit. This does not affect the validity of a notice to quit given by only one or some of the tenants.
