看看原来的lease有没有类似这么一段话

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.

如果没有这么一段话，要看当地法律如何填补空白。，一般来说合同是可以单方替换的，比如你的房贷可以被一个银行卖给另外一个银行，你还是要准时交费。
