Section 41. On application to a court of competent jurisdiction by any judgment creditor of a partner, the court may charge the partnership interest of the partner with payment of the unsatisfied amount of the judgment with interest.

This chapter shall not deprive any partner of the benefit of any exemption laws applicable to his partnership interest.
