N.J. Stat. § 40:23-6.24
It shall be lawful for each such board of chosen freeholders to appropriate and raise funds annually for the purposes aforesaid in the same manner as appropriations are made for other county purposes. In the event that any such board of chosen freeholders shall designate the county welfare board as its agent, it may turn such moneys over to such county welfare board to meet the costs incurred under any such contracts. If, during the fiscal year in which this act shall be adopted, any board of chosen freeholders shall have made no provision in its annual budget for the necessary funds for the aforesaid purposes during such fiscal year, said board may appropriate and use any county funds not otherwise appropriated or dedicated, or may appropriate and raise such funds as may be necessary for such purpose during such fiscal year, and may borrow the same, or any part thereof, on the credit of the county, and may issue obligations therefor in the same manner as other similar obligations are issued under the provisions of the Title to which this act is a supplement.
