CA Gov't Code Section 75098

If an allowance is paid under this article no payment shall be made pursuant to Section 75104 or Section 75104.5, provided however, that if the prospective allowance payable to the children under the provisions of this article upon the death of a judge or retired judge without a surviving spouse is less than the aggregate amount payable under the provisions of Sections 75104 and 75104.5, and the judge has designated his children as his beneficiaries, the guardian of the children under age 18 and the children over 18 may elect to take the latter amount and waive the allowance otherwise payable under this article.
