A monthly allowance equivalent to the allowance payable pursuant to Section 75077 shall be paid, in lieu of any other surviving children's benefits, to the guardian of surviving unmarried children while under 18 years of age and the surviving unmarried children over age 18 and under age 22 who are full-time students, and to the guardian of a surviving unmarried child over age 18 who is disabled by a condition which disabled that child prior to attaining age 18 and which has continued without interruption after age 18, until the disability ceases, of a judge who dies after retirement under this chapter without a surviving spouse or in the event that the surviving spouse of a judge dies after his or her death while receiving an allowance payable pursuant to Section 75077. The amount paid shall be divided equally among the children.
"Children," for the purposes of this section, shall be limited to dependent children and stepchildren of the judge at the time of his or her retirement.
"Disabled" or "disability" means, with respect to qualification for an allowance to a surviving child, inability to engage in any substantial gainful occupation by reason of any physical or mental impairment which is determined by the board, on the basis of competent medical or psychiatric opinion, to be of permanent or extended duration.
Election to come within the benefits of this article as provided in Section 75096 shall be deemed to include an election to enjoy the benefits of this section, and contributions shall be made by any retired judge so electing as fixed by Section 75097 to be deducted from the judge's retirement allowance during his or her lifetime as provided in Section 75106.5.
The benefit payable under this section to a disabled child shall not exceed 25 percent of the compensation payable, at the time payments of the allowance fall due, to the judge holding the office which the retired judge last held prior to discontinuance of service as a judge.
The amendments made to this section during the 1991-92 Regular Session shall be applicable to any retired judge who elects to be subject to the amended provisions of this section on or before January 1, 1993. A retired judge so electing shall pay all the contributions he or she would have made pursuant to Section 75097 had he or she been covered by this article at the time of retirement.
