Wis. Stat. § 701.0405: Charitable purposes; enforcement.

(2) If the terms of a charitable trust do not indicate a particular charitable purpose or beneficiary, or designate persons or procedures for selecting charitable purposes or beneficiaries, the court may select one or more charitable purposes or beneficiaries. The selection must be consistent with the settlor’s intention to the extent it can be ascertained.

(3) The settlor of a charitable trust or his or her designees, whether identified within or without the terms of the trust, or a charitable entity named in the trust instrument, or the attorney general, or a cotrustee, or such other person the court determines to have sufficient interest may maintain a proceeding to enforce the trust.
