(a) General rule.--The association's right to terminate a cooperative interest shall be exercised by judicial sale of the cooperative interest in like manner as a foreclosure upon a leasehold interest in real estate. Where the articles of incorporation, declaration or bylaws provide a fixed price or formula for determining the maximum amount which the owner of the cooperative interest may receive upon transfer or where the articles of incorporation, declaration or bylaws provide an option, but not a right of first refusal, in the association to acquire the cooperative interest at a fixed price or price determined by formula and where the association has obtained a judgment authorizing the sale of the cooperative interest, the association may acquire the cooperative interest by payment of such amount to the owner of the cooperative interest or to the sheriff at any time prior to the sale. In case of judicial sale or payment to the sheriff in lieu of sale, liens and encumbrances shall be divested and proceeds distributed as if the right to terminate were deemed to be a lien for nonpayment of assessments under section 4315 (relating to lien for assessments), arising as of the date of commencement of the action.

(b) Enforcement of proprietary lease.--The association shall have the right, at its option, to enforce the provisions of the proprietary lease, including termination of the cooperative interest for default thereunder, under the provisions of the act of April 6, 1951 (P.L. 69, No. 20),¹ known as The Landlord and Tenant Act of 1951, as amended, or by any other means available to it at law or in equity. In any such case, the court shall have the power to order judicial sale of the cooperative interest. In the event the proprietary lessee appeals an adverse decision in any court in which the association seeks to enforce its rights, the appeal may be dismissed, upon motion of the association, by the court in which the appeal is pending, if the proprietary lessee has not paid all the lessee's common expense assessments as they become due both prior to and during the pendency of the appeal, subject to any final judicial determination of the proprietary lessee's liability to make the payments if that is an issue in the appeal.
