N.J. Stat. § 43:9A-3
A person so retired shall be entitled to receive, for and during his natural life, a pension of such sum as the board of chosen freeholders determines by resolution, but not less than one-half of the salary then being received by him for his service. The widow of a person so retired, or the widow of a clerk or deputy clerk of a county district court of a county of the first class having a population of over eight hundred thousand who shall have been for twenty-five years continuously in such office or position and in the office or position of clerk and assistant clerk of a district court of a city within such county and who shall have died while in such office or position shall be entitled to receive, for and during her natural life, or so long as she remains unmarried, a pension of such sum as the board of chosen freeholders determines by resolution, but not less than one-half of the salary being received by the said clerk or deputy clerk for his service at the time of his death or retirement; provided, however, that no pension shall be paid to such a widow except if she married such employee prior to the retirement of such employee and prior to the time when such employee reached the age of fifty years. No such surviving spouse shall be eligible for any benefit hereunder who was or shall be more than fifteen years younger than the employee at the time of their marriage, if such marriage occurs hereafter.
The foregoing provision for payment of a pension to the widow of such clerk or deputy clerk shall become effective provided such clerk or deputy clerk shall pay to the county treasurer a sum equal to two per centum (2%) of the amount of his salary from the first day of July, one thousand nine hundred and forty-five, to the date of the approval of this act; and an additional sum of two per centum (2%) of the amount of his salary in addition to three per centum (3%) provided for in section six of the act of which this act is amendatory in the same manner as is provided for the payments to be made by virtue of such section six.
The pension shall be paid in the same manner and in the same installments as his salary was theretofore payable.
