(1) If the lessor, prior to the devolution of ownership, disposes over the rent attributable to the period in which the acquirer is entitled, then the disposition is effective to the extent that it relates to the rent for the calendar month current at the time when the ownership devolved. If ownership devolves after the fifteenth day of the month, then the disposition also is effective to the extent that it relates to the rent for the following calendar month.
(2) The acquirer must allow a disposition over the rent for a later period to apply against them if they had knowledge of it at the time of the devolution of ownership.
