Cal. PROB § 2631

(a) Upon the death of the ward or conservatee, the guardian or conservator may contract for and pay a reasonable sum for the expenses of the last illness and the disposition of the remains of the deceased ward or conservatee, and for unpaid court-approved attorney’s fees, and may pay the unpaid expenses of the guardianship or conservatorship accruing before or after the death of the ward or conservatee, in full or in part, to the extent reasonable, from any personal property of the deceased ward or conservatee which is under the control of the guardian or conservator.

(b) If after payment of expenses under subdivision (a), the total market value of the remaining estate of the decedent does not exceed the amount determined under Section 13100, the guardian or conservator may petition the court for an order permitting the guardian or conservator to liquidate the decedent’s estate. The guardian or conservator may petition even though there is a will of the decedent in existence if the will does not appoint an executor or if the named executor refuses to act. No notice of the petition need be given. If the order is granted, the guardian or conservator may sell personal property of the decedent, withdraw money of the decedent in an account in a financial institution, and collect a debt, claim, or insurance proceeds owed to the decedent or the decedent’s estate, and a person having possession or control shall pay or deliver the money or property to the guardian or conservator.

(c) After payment of expenses, the guardian or conservator may transfer any remaining property as provided in Division 8 (commencing with Section 13000). For this purpose, the value of the property of the deceased ward or conservatee shall be determined after the deduction of the expenses so paid.
