(1) The lessee may object to the notice of termination issued by the lessor and may demand of the latter that they continue the lease if termination of the lease would constitute a hardship for the lessee, their family or another member of their household that is not justifiable even considering the legitimate interests of the lessor. This does not apply if a reason exists that entitles the lessor to terminate the lease for cause without notice.
(2) Hardship is given also if appropriate substitute residential space cannot be procured on reasonable terms.
(3) In considering the legitimate interests of the lessor, only the reasons stated in the letter giving notice of termination under section 573 (3) are taken into account, except where the reasons arose subsequently.
(4) A deviating agreement to the disadvantage of the lessee is ineffective.
