Wis. Stat. § 702.505

Any person acting without actual notice of claims of creditors under this subchapter incurs no liability to those creditors for transferring property that is subject to a power of appointment or that has been appointed. A purchaser without actual notice and for a valuable consideration takes an interest in property, legal or equitable, and takes the interest free of any rights that a powerholder’s creditor may have under this subchapter.
