Cal. Civ. Proc. Code § 674
(a) Except as otherwise provided in Section 4506 of the Family Code, an abstract of a judgment or decree requiring the payment of money shall be certified by the clerk of the court where the judgment or decree was entered and shall contain all of the following:
(b) An abstract of judgment, recorded after January 1, 1979, that does not list the social security number and driver’s license number of the judgment debtor, or either of them, as required by subdivision (a) or by Section 4506 of the Family Code, may be amended by the recording of a document entitled “Amendment to Abstract of Judgment.” The Amendment to Abstract of Judgment shall contain all of the information required by this section or by Section 4506 of the Family Code, and shall set forth the date of recording and the book and page location in the records of the county recorder of the original abstract of judgment.
A recorded Amendment to Abstract of Judgment shall have priority as of the date of recordation of the original abstract of judgment, except as to any purchaser, encumbrancer, or lessee who obtained their interest after the recordation of the original abstract of judgment but prior to the recordation of the Amendment to Abstract of Judgment without actual notice of the original abstract of judgment. The purchaser, encumbrancer, or lessee without actual notice may assert as a defense against enforcement of the abstract of judgment the failure to comply with this section or Section 4506 of the Family Code regarding the contents of the original abstract of judgment notwithstanding the subsequent recordation of an Amendment to Abstract of Judgment. With respect to an abstract of judgment recorded between January 1, 1979, and July 10, 1985, the defense against enforcement for failure to comply with this section or Section 4506 of the Family Code may not be asserted by the holder of another abstract of judgment or involuntary lien, recorded without actual notice of the prior abstract, unless refusal to allow the defense would result in prejudice and substantial injury as used in Section 475. The recordation of an Amendment to Abstract of Judgment does not extend or otherwise alter the computation of time as provided in Section 697.310.
