Section 167 - Termination of contract on contract-holder’s notice
398.Where the contract-holder gives up possession of the dwelling on or before the date specified in the notice given under the term of the contract incorporating section 163, the contract runs until that date. Where the contract-holder gives up possession after the date specified in the notice and no order for possession is made, the contract ends on the date the contract-holder gives up possession. If a possession order is made on the ground in section 165, the contract will end in accordance with section 206 (which sets out the effects of a possession order).
399.If the contract-holder, before the end of the notice period, withdraws the notice given under the term of the contract incorporating section 163 and the landlord does not object to this in writing, within a reasonable period, the notice ceases to have effect.
