Cal. Commercial Code § 12104

(a) This section applies to the acquisition and purchase of rights in a controllable account or controllable payment intangible, including the rights and benefits under subdivisions (c), (d), (e), (g), and (h) of a purchaser and qualifying purchaser, in the same manner this section applies to a controllable electronic record. (b) To determine whether a purchaser of a controllable account or a controllable payment intangible is a qualifying purchaser, the purchaser obtains control of the account or payment intangible if it obtains control of the controllable electronic record that evidences the account or payment intangible. (c) Except as provided in this section, law other than this division determines whether a person acquires a right in a controllable electronic record and the right the person acquires. (d) A purchaser of a controllable electronic record acquires all rights in the controllable electronic record that the transferor had or had power to transfer, except that a purchaser of a limited interest in a controllable electronic record acquires rights only to the extent of the interest purchased. (e) A qualifying purchaser acquires its rights in the controllable electronic record free of a claim of a property right in the controllable electronic record. (f) Except as provided in subdivisions (a) and (e) for a controllable account and a controllable payment intangible or law other than this division, a qualifying purchaser takes a right to payment, right to performance, or other interest in property evidenced by the controllable electronic record subject to a claim of a property right in the right to payment, right to performance, or other interest in property. (g) An action may not be asserted against a qualifying purchaser based on both a purchase by the qualifying purchaser of a controllable electronic record and a claim of a property right in another controllable electronic record, whether the action is framed in conversion, replevin, constructive trust, equitable lien, or other theory. (h) Filing of a financing statement under Division 9 (commencing with Section 9101) is not notice of a claim of a property right in a controllable electronic record.
