(2) The reasonable costs of partition, including reasonable attorney fees and disbursements, that are for services performed for the common benefit of all parties, shall be paid by the parties that will share in the lands divided in proportion to their respective interests therein, and shall be included and specified in the judgment. They shall be a lien on the several shares, and the judgment may be enforced by execution against the parties separately. When, however, a controversy arises between some of the parties only, the court may require the expense of such controversy to be paid by any of, or all, the parties thereto. [Amended by 1971 c.502 §1; 2003 c.576 §368]
