Cal. Health & Safety Code § 7101 — Custody, and Duty of Interment

When any decedent leaves an estate in this state, the reasonable cost of interment and an interment plot of sufficient size to constitute a family plot and memorial including reasonable sums for either, or both, general and special endowment care of the plot proportionate to the value of the estate and in keeping with the standard of living adopted by the decedent prior to his demise, together with interest thereon from 60 days after the date of death, shall be considered as a part of the funeral expenses of the decedent and shall be paid as a preferred charge against his estate as provided in the Probate Code.

Reasonable costs of funeral services, together with interest thereon from 60 days after the date of death, shall be considered as a part of the funeral expenses of the decedent and shall be paid as a preferred charge against his estate as provided in the Probate Code.

If a claim for mortuary and funeral services, an interment plot or memorial is rejected the burden of proving that the cost of the funeral service, interment plot or memorial is disproportionate to the value of the estate and the standard of living adopted by the decedent while living shall be upon the executor or administrator rejecting the claim. This chapter does not prohibit any relative or friend of a decedent from assuming the duty or paying the expense of interment or the funeral services.
