Cal. Probate Code § 11623

(a) Notwithstanding Section 11601, if authority is granted to administer the estate without court supervision under the Independent Administration of Estates Act, Part 6 (commencing with Section 10400): (1) The personal representative may petition the court for an order for preliminary distribution on notice as provided in Section 1220. Notwithstanding subdivision (c) of Section 1220, the court may not dispense with notice unless the time for filing creditor claims has expired. (2) The aggregate of all property distributed under this section shall not exceed 50 percent of the net value of the estate. For the purpose of this subdivision, “net value of the estate” means the excess of the value of the property in the estate, as determined by all inventories and appraisals on file with the court, over the total amount of all creditor claims and of all liens and encumbrances recorded or known to the personal representative not included in a creditor claim, excluding any estate tax lien occasioned by the decedent’s death. (b) Nothing in this section limits the authority of the personal representative to make preliminary distribution under other provisions of this chapter, whether or not authority is granted to administer the estate under the Independent Administration of Estates Act, Part 6 (commencing with Section 10400).
