(a) A member with at least 20 years of service shall receive retirement benefits of $1,700.00 per month upon retirement, provided that at least 12 years of such service shall have been served as a clerk, and the member must have served continuously as a clerk for the four years immediately preceding the member's retirement. Subject to the restrictions set out in this subsection, in computing such service, a member also may include service as a deputy clerk of the superior court and not more than four years of service as a member of the armed forces of the United States on active duty during any period of time in which the United States was engaged in an armed conflict, regardless of whether a state of war had been declared by Congress, provided that no service as a member of the armed forces of the United States shall be deemed as service for purposes of obtaining retirement benefits under this chapter if such service has or will be used in the determination of the member's eligibility for retirement benefits or allowances from any other state or federal retirement program, excluding social security. A clerk of the superior court may not include service for eligibility purposes for years in which the clerk has not completed the training requirements set out in paragraph (1) of subsection (c) of Code Section 15-6-50.

(b) If a member is eligible to retire under subsection (a) of this Code section but does not retire and continues to serve as clerk, he or she shall be entitled to receive, upon retirement, the amount to which he or she would have been entitled under subsection (a) of this Code section; and, in addition, for each year of service beyond the required 20 years, he or she shall receive an additional 5 percent of the amount he or she would be entitled to under subsection (a) of this Code section.

(c) In lieu of the retirement benefits provided in subsections (a) and (b) of this Code section, a member, upon retirement, may elect to receive 90 percent of the benefits the member is entitled to receive under subsections (a) and (b) of this Code section during the remainder of the member's life; and, after the member's death, the member's surviving spouse shall receive a monthly sum during the lifetime of the surviving spouse equal to 50 percent of the amount which the member would have received had the member elected the full benefits provided under subsections (a) and (b) of this Code section. In order to be eligible for such benefits, the surviving spouse must have been married to the member for at least six years immediately preceding the member's death. Such benefits shall not commence until after the surviving spouse reaches 55 years of age.

(d) A member with at least 16 years of service either as a clerk or deputy clerk shall receive retirement benefits of $1,360.00 per month upon retirement, provided that at least eight years of such service shall have been served as a clerk, and the member must have served continuously as a clerk for the four years immediately preceding the member's retirement. No other type of service shall be counted toward such retirement benefits.

(e) A member with at least 12 years of service either as a clerk or deputy clerk shall receive retirement benefits of $1,020.00 per month upon retirement, provided that at least eight years of such service shall have been served as a clerk, and the member must have served continuously as a clerk for the four years immediately preceding the member's retirement. No other type of service shall be counted toward such retirement benefits.

(f) Any other provisions of this chapter to the contrary notwithstanding, all members who retire on or after April 1, 1976, for whatever reason and who otherwise meet the requirements for retirement benefits under either subsection (d) or (e) of this Code section shall be entitled to an additional benefit based on service in excess of the minimum required for such retirement benefits, provided that such service is of the kind for which credit toward retirement benefits would be given under subsection (d) or (e) of this Code section. The amount of the retirement benefit shall be based on the ratio that the total number of years served bears to the minimum number of years required for benefits under subsection (d) or (e) of this Code section, as appropriate. For example, the following table is illustrative of the additional benefits computation under this Code section:

Years_of_Service at_Retirement Benefits_Received

13 Thirteen-twelfths of the benefits provided in subsection (e) of this Code section

14 Fourteen-twelfths of the benefits provided in subsection (e) of this Code section

15 Fifteen-twelfths of the benefits provided in subsection (e) of this Code section

17 Seventeen-sixteenths of the benefits provided in subsection (d) of this Code section

18 Eighteen-sixteenths of the benefits provided in subsection (d) of this Code section

19 Nineteen-sixteenths of the benefits provided in subsection (d) of this Code section

(g) No person shall receive credit toward the retirement benefits set forth in subsections (a) and (b) of this Code section for any service performed after February 15, 1952, unless payment for the period covered by such service has been made to the board. No person shall be eligible for the benefits provided in this Code section unless his or her official duties have terminated and he or she files an application for benefits within 90 days, or as soon thereafter as possible, from the termination of his or her official duties.
