New Jersey Statutes Title 46. Property 46 § 8B-22

(a) A unit may be sold by the sheriff on execution, free of any claim, not a lien of record, for common expenses or other assessments by the association, but any funds derived from such sale remaining after satisfaction of prior liens and charges but before distribution to the previous unit owner, shall be applied to payment of such unpaid common expenses or other assessments if written notice thereof shall have been given to the sheriff before distribution. Any such unpaid common expenses which shall remain uncollectible from the former unit owner for a period of more than 60 days after such sheriff's sale may be reassessed by the association as common expenses to be collected from all unit owners including the purchaser who acquired title at the sheriff's sale, his successors and assigns. Unless prohibited by the master deed or bylaws, the association may bid in and purchase the unit at a sheriff's sale, and acquire, hold, lease, mortgage and convey the same.

(b) Notwithstanding any foreclosure, tax sale, or other forced sale of a unit, all applicable provisions of the master deed and bylaws, shall be binding upon any purchaser at such sale to the same extent as they would bind a voluntary grantee except that such purchaser shall not be liable for the share of common expenses or other assessments by the association pertaining to such unit or chargeable to the former owner which became due prior to such sale except as otherwise provided in subsection (a) of this section or section 21 of P.L.1969, c. 257 (C.46:8B-21).
