N.J. Stat. § 44:7-7
The board of chosen freeholders of each of the several counties shall cause to be established in the respective counties, where such is not already established, a county welfare board, having as one of its duties the supervision of old age assistance, but nothing in this chapter shall be construed to affect the membership of any welfare board established prior to March 16, 1936, or the term of service of any employee theretofore appointed by any such welfare board. Such boards are hereby created corporate entities, with power to sue and be sued, to use a common seal and to make bylaws. The members of said welfare board shall be appointed by the boards of chosen freeholders in and for the respective counties, and shall be constituted and composed as provided in R.S. 44:1-11. Citizen members shall hold their offices for five years, except that the first appointments shall be respectively for 1, 2, 3, 4 and 5 years, which terms, as to duration, shall be in the order of appointments as made and indicated. Vacancies in such offices shall be filled for the unexpired term only. The holding of any other office by any member of said county welfare board shall not constitute such holding as incompatible with his office as member of such county welfare board. They shall meet regularly once each month, and at such other times as may be necessary or as they may by rule provide. Attendance at any meeting of any such board by four members, at least two of whom shall be citizen members, may constitute a quorum for the transaction of business under this chapter. They shall serve without compensation, but their necessary expenses shall be allowed and paid in the same manner as other expenses are paid by the county welfare board.
