Section 142-6 - Registration as to principal and interest(a) If, upon the registration of any such bond or certificate dated prior to January 1, 1965, or at any time after such registration, the coupons thereto attached, evidencing all interest to be paid thereon to the date of maturity, shall be surrendered, such coupons shall be canceled by the Treasurer, and he shall sign a statement endorsed upon such bond or certificate of the cancellation of all unmatured coupons and of the fact that such bond or certificate has been converted into a fully registered bond or certificate, and shall make like entry in the said register. Thereafter the interest evidenced by such canceled coupons shall be paid at the time provided therein, to the registered owner or his legal representatives, in New York exchange, mailed to his address, unless he shall have requested the State Treasurer to pay such interest in funds current at the State capital, which request shall be entered in the said register.(b) If, upon the registration of any such bond or certificate dated on or after January 1, 1965, or at any time after such registration, the coupons thereto attached, evidencing all interest to be paid thereon to the date of maturity, shall be surrendered, such coupons shall be detached and retained in the custody of the State Treasurer, and the State Treasurer shall endorse upon such bond or certificate the fact that such bond or certificate has been converted into a fully registered bond or certificate, and shall make like entry in said register. Thereafter the interest evidenced by such detached coupons shall be paid at the times provided therein to the registered owner or his legal representatives, in New York exchange, mailed to his address, unless he shall have requested the State Treasurer to pay such interest in funds current at the State capital, which request shall be entered in said register. Any such bond or certificate, if converted into a bond or certificate registered as to both principal and interest, may be reconverted at the expense of the registered owner into a coupon bond or certificate upon presentation thereof to the State Treasurer, accompanied by an instrument duly executed by the registered owner or his legal representatives in such form as shall be satisfactory to the State Treasurer; upon any such reconversion the State Treasurer shall reattach thereto the coupons representing the interest to become due thereafter on such bond or certificate to the date of maturity and shall make notation upon such bond or certificate whether such bond or certificate is registered as to principal alone or is payable to bearer, and shall make like entry in said register and he shall cancel any detached coupons retained by him representing interest that has been paid. 1856, c. 16; 1883, c. 25, s. 2; Code, s.3569; 1887, c. 287, s. 2; Rev., s. 5026; C.S., s. 7406; Ex.Sess. 1921, c. 66, s. 5; 1965, c. 181, s. 1.
