An owner-occupant of property being acquired may waive his or her right to receive any relocation payments or services under this subchapter if the property being acquired is not contiguous to any property which may be acquired by the condemnor and is not part of a previously identified or proposed project where it is reasonable to conclude that acquisition by the condemnor may occur in the foreseeable future. Prior to the execution of any waiver under this section, the condemnor shall provide to the owner-occupant, in writing, full information about the specific payments and services being waived by the owner-occupant. The department of administration shall by rule establish procedures for relocation assistance waivers under this section to ensure that the waivers are voluntarily and knowledgeably executed.
