The probate fee schedule is published in the California Probate Code and is applicable in the entire state:

(5) One-half of 1 percent on the next fifteen million dollars ($15,000,000).
(6) For all amounts above twenty-five million dollars ($25,000,000), a reasonable amount to be determined by the court.
(b) For the purposes of this section, the value of the estate accounted for by the personal representative is the total amount of the appraisal of property in the inventory, plus gains over the appraisal value on sales, plus receipts, less losses from the appraisal value on sales, without reference to encumbrances or other obligations on estate property.
Prob C § 10811 (a) Subject to the provisions of this part, in addition to the compensation provided by Section 10810, the court may allow additional compensation for extraordinary services by the attorney for the personal representative in an amount the court determines is just and reasonable.
Prob C § 10813 An agreement between the personal representative and the attorney for higher compensation for the attorney than that provided by this part is void.
This means that the Cost of Probate is the same across law firms - what makes the difference is choosing a Firm that specializes in Probate and is most efficient, easy to communicate with and gets you through the long probate process with no delays.
