CA Prob Code Section 8441

(a)

Except as provided in subdivision (b), persons and their nominees are entitled to appointment as administrator with the will annexed in the same order of priority as for appointment of an administrator.

(b)

A person who takes under the will has priority over a person who does not, but the court in its discretion may give priority to a person who does not take under the will if the person is entitled to a statutory interest that is a substantially greater portion of the estate than the devise to the person who takes under the will and the priority appears appropriate under the circumstances. A person who takes more than 50 percent of the value of the estate under the will or the person’s nominee, or the nominee of several persons who together take more than 50 percent of the value of the estate under the will, has priority over other persons who take under the will.
