California Code, Code of Civil Procedure - CCP § 488.500

(a) A levy on property under a writ of attachment creates an attachment lien on the property from the time of levy until the expiration of the time provided by Section 488.510.

(b) Except as provided in subdivisions (c) and (d), if property subject to an attachment lien is transferred or encumbered, the property transferred or encumbered remains subject to the lien after the transfer or encumbrance to the same extent that the property would remain subject to an execution lien pursuant to Sections 697.720 to 697.750, inclusive.

(c) Except as otherwise provided in this title, if equipment is attached pursuant to Section 488.375 or farm products or inventory is attached pursuant to Section 488.405, the attachment lien on the property covered by the attachment lien has the same force and effect as a judgment lien on personal property created at the same time would have pursuant to Sections 697.590 to 697.620, inclusive.

(d) If equipment consisting of a vehicle, vessel, mobilehome, or commercial coach is attached pursuant to Section 488.385, the attachment lien on the specified property does not affect the rights of a person who is a bona fide purchaser or encumbrancer and obtains possession of both the property and its certificate of ownership issued by the Department of Motor Vehicles or its certificate of title or registration card issued by the Department of Housing and Community Development. If the levying officer obtains possession of the certificate of ownership or certificate of title or registration card, the attachment lien has the priority of the lien of a lien creditor under Sections 9317 and 9323 of the Commercial Code as of the time possession is obtained by the levying officer. If the levying officer does not obtain possession of the certificate of ownership or certificate of title or registration card, the attachment lien has the same force and effect as an unperfected security interest that attached at the same time as the notice of attachment was filed.

(e) If an attachment lien is created on property that is subject to the lien of a temporary protective order or a lien under Article 1 (commencing with Section 491.110) of Chapter 11, the priority of the attachment lien relates back to the date the earlier lien was created. Nothing in this subdivision affects priorities or rights of third persons established while the lien of the temporary protective order or the lien under Article 1 (commencing with Section 491.110) of Chapter 11 was in effect as determined under the law governing the effect of such lien.
