Wis. Stat. § 150.41

No person may transfer through sale, lease or donation any approval granted under this subchapter. The sale, lease or donation of a nursing home before the completion or licensure of a project at that nursing home voids the approval. This section does not apply to transfers of stock within a corporation that do not alter the controlling interest in the corporation or to transfers of interests within a limited liability company that do not alter the controlling interest in the limited liability company.
