(c) Upon the sale or conveyance of an apartment, all unpaid assessments against a co-owner for his or her pro rata share in the expenses to which subsection (a) of this section refers shall first be paid out of the sales price or by the acquirer in preference over any other assessments or charges of whatever nature except the following:

(1) Assessments, liens, and charges for taxes past due and unpaid on the apartment; and

(2) Payments due under mortgage instruments of encumbrance duly recorded.

(d) The purchaser of an apartment shall be jointly and severally liable with the seller for the amounts owing by the latter under subsection (a) of this section up to the time of the conveyance, without prejudice to the purchaser's right to recover from the other party the amounts paid by him or her as the joint debtor.
