Every probate court shall have the power to follow the course of equity insofar as necessary to fulfill the mandates of title 33 of the General Laws, specifically: the replacement, removal, or filling of any vacancy of any trustee under a trust established under a will; or tax minimization or estate planning under § 33-15-37.1.
