Cal. Civ. Code § 1899.7

(a) Except as provided in subdivision (b), if a museum is unable to give the lender the notice required by subdivision (d) of Section 1899.3 of injury to or loss of property on loan by mail, the museum shall be deemed to have given the lender notice of any injury or loss if in addition to the information required by subdivision (b) of Section 1899.2 the published notice includes a statement containing substantially the following information:

“The records of (name of museum)indicate that you have property on loan to it. Your failure to notify it in writing of a change of address or ownership of property on loan or to contact it in writing regarding the loan may result in the loss of rights in the loaned property. See California Civil Code Sections 1899, et seq.”

(b) If, within three years of giving notice of injury to or loss of loaned property by publishing the notice set forth in subdivision (a), the museum receives a notice from a claimant pursuant to Section 1899.4, the museum shall promptly advise the claimant in writing of the nature of the injury to or the fact of the loss of property on loan and the approximate date thereof. For the purposes of the limitation period in Section 1899.8, if the museum mails the information to the claimant within 30 days of the date the museum receives the notice from the claimant, the museum shall be deemed to have given the claimant notice of the injury to or loss of property on loan on the date notice by publication pursuant to subdivision (a) was completed.
