For the purpose of computing, under this subsection, the annuity of a child that commences on or after January 1, 1987, the figures $8,424, $2,808, $10,110, and $3,370 (provided in paragraphs (2) and (3)) shall be increased by the total percentage of the increases allowed and in force with respect to retirement salaries of judges under section 11-1571(a) of this title on or after such date. An annuity payable to a widow or widower under this section shall be terminable upon death or upon remarriage prior to the attainment of fifty-five years of age. The annuity payable to a child shall be terminable upon the child's death or marriage or ceasing to be a child as defined in section 11-1561(8). In case of the death of a widow or widower of a judge leaving a child or children of the judge surviving, the annuity of such child or children shall be recomputed and paid as provided in paragraph (3) of this subsection. In any case in which the annuity of a child is terminated, the annuities of any remaining child or children, based upon the service of the same judge, shall be recomputed and paid as though the child whose annuity was terminated had not survived the judge.
