Chapter 3. Official Writings Affecting Property of California Evidence Code >> Division 11. >> Chapter 3.

(a) The record of an instrument or other document purporting to establish or affect an interest in property is prima facie evidence of the existence and content of the original recorded document and its execution and delivery by each person by whom it purports to have been executed if:
  (1) The record is in fact a record of an office of a public entity; and
  (2) A statute authorized such a document to be recorded in that office.
  (b) The presumption established by this section is a presumption affecting the burden of proof.

(a) Subject to subdivisions (b) and (c), when in any action it is desired to prove the contents of the official record of any writing lost or destroyed by conflagration or other public calamity, after proof of such loss or destruction, the following may, without further proof, be admitted in evidence to prove the contents of such record:
  (1) Any abstract of title made and issued and certified as correct prior to such loss or destruction, and purporting to have been prepared and made in the ordinary course of business by any person engaged in the business of preparing and making abstracts of title prior to such loss or destruction; or
  (2) Any abstract of title, or of any instrument affecting title, made, issued, and certified as correct by any person engaged in the business of insuring titles or issuing abstracts of title to real estate, whether the same was made, issued, or certified before or after such loss or destruction and whether the same was made from the original records or from abstract and notes, or either, taken from such records in the preparation and upkeeping of its plant in the ordinary course of its business.
  (b) No proof of the loss of the original writing is required other than the fact that the original is not known to the party desiring to prove its contents to be in existence.
  (c) Any party desiring to use evidence admissible under this section shall give reasonable notice in writing to all other parties to the action who have appeared therein, of his intention to use such evidence at the trial of the action, and shall give all such other parties a reasonable opportunity to inspect the evidence, and also the abstracts, memoranda, or notes from which it was compiled, and to take copies thereof.

A deed of conveyance of real property, purporting to have been executed by a proper officer in pursuance of legal process of any of the courts of record of this state, acknowledged and recorded in the office of the recorder of the county wherein the real property therein described is situated, or the record of such deed, or a certified copy of such record, is prima facie evidence that the property or interest therein described was thereby conveyed to the grantee named in such deed. The presumption established by this section is a presumption affecting the burden of proof.

A certificate of purchase, or of location, of any lands in this state, issued or made in pursuance of any law of the United States or of this state, is prima facie evidence that the holder or assignee of such certificate is the owner of the land described therein; but this evidence may be overcome by proof that, at the time of the location, or time of filing a preemption claim on which the certificate may have been issued, the land was in the adverse possession of the adverse party, or those under whom he claims, or that the adverse party is holding the land for mining purposes.

Duplicate copies and authenticated translations of original Spanish title papers relating to land claims in this state, derived from the Spanish or Mexican governments, prepared under the supervision of the Keeper of Archives, authenticated by the Surveyor-General or his successor and by the Keeper of Archives, and filed with a county recorder, in accordance with Chapter 281 of the Statutes of 1865-66, are admissible as evidence with like force and effect as the originals and without proving the execution of such originals.
