看看原來的lease有沒有類似這麽一段話

X. Successors and Assigns
This Agreement is binding on all persons who may succeed to the rights of [Landowner] including but not
limited to heirs, executors, assigns, and purchasers, as applicable, and in accordance with this Agreement.

[Farmer] may not assign this Lease Agreement and the lease interest in the Premises represented herein,
sublet all or any part of the Premises, or allow any person to occupy the Premises for an extended period
without, in each instance, [Landowner’s] express written permission.

如果沒有這麽一段話，要看當地法律如何填補空白。，一般來說合同是可以單方替換的，比如你的房貸可以被一個銀行賣給另外一個銀行，你還是要準時交費。
