California Code, Probate Code - PROB § 330

(a) Except as provided in subdivision (b), a public administrator, government official, law enforcement agency, the hospital or institution in which a decedent died, or the decedent's employer, may, without the need to wait 40 days after death, deliver the tangible personal property of the decedent in its possession, including keys to the decedent's residence, to the decedent's surviving spouse, relative, or conservator or guardian of the estate acting in that capacity at the time of death.

(b) A person shall not deliver property pursuant to this section if the person knows or has reason to believe that there is a dispute over the right to possession of the property.

(c) A person that delivers property pursuant to this section shall require reasonable proof of the status and identity of the person to whom the property is delivered, and may rely on any document described in subdivision (d) of Section 13104 as proof of identity.

(d) A person that delivers property pursuant to this section shall, for a period of three years after the date of delivery of the property, keep a record of the property delivered and the status and identity of the person to whom the property is delivered.

(e) Delivery of property pursuant to this section does not determine ownership of the property or confer any greater rights in the property than the recipient would otherwise have and does not preclude later proceedings for administration of the decedent's estate.  If proceedings for administration of the decedent's estate are commenced, the person holding the property shall deliver it to the personal representative on request by the personal representative.

(f) A person that delivers property pursuant to this section is not liable for loss or damage to the property caused by the person to whom the property is delivered.
