California Code, Code of Civil Procedure - CCP § 697.340

(a) A judgment lien on real property attaches to all interests in real property in the county where the lien is created (whether present or future, vested or contingent, legal or equitable) that are subject to enforcement of the money judgment against the judgment debtor pursuant to Article 1 (commencing with Section 695.010) of Chapter 1 at the time the lien was created, but does not reach rental payments, a leasehold estate with an unexpired term of less than two years, the interest of a beneficiary under a trust, or real property that is subject to an attachment lien in favor of the creditor and was transferred before judgment.

(b) If any interest in real property in the county on which a judgment lien could be created under subdivision (a) is acquired after the judgment lien was created, the judgment lien attaches to such interest at the time it is acquired.
