Cal. Civil Code § 886.020

If the party to whom title to real property is to be conveyed pursuant to a recorded contract for the sale of real property fails to satisfy the specified conditions set forth in the contract and does not seek performance of the contract or restitution of amounts paid under the contract, the party shall, upon demand therefor made after the operative date of this chapter, execute a release of the contract, duly acknowledged for record, to the party who agreed to convey title. Willful violation of this section by the party to whom title is to be conveyed without good cause makes the party liable for the damages the party who agreed to convey title sustains by reason of the violation, including but not limited to court costs and reasonable attorney’s fees in an action to clear title to the real property. Nothing in this section makes a release or a demand therefor a condition precedent to an action to clear title to the real property.
