The costs of partition, including fees or referees and other disbursements, shall be paid by the parties respectively entitled to share in the lands divided in proportion to their respective interests in the property, and may be included and specified in the judgment. In that case they are a lien on the several shares, and the judgment may be enforced by execution against the parties separately. When, however, a litigation arises between some of the parties only, the court may require the expenses of the litigation to be paid by any or all of the parties to the litigation.
