LivingLies: “Where the nonjudicial post-foreclosure trustee sale is not property initiated, ” … a borrower may base a wrongful foreclosure claim on allegations that the foreclosing party acted without authority because the assignment by which it purportedly became beneficiary under the deed of trust was not merely voidable but void.” (Yvanonova, supra, at pp. 851-852.) “A void contract is without legal effect. (Rest.2d Contracts,§ 7, com. A.) “It binds no one and is a mere nullity.” (Little v. CFS Service Corp. (1987) 188 Cal.App.3d 1354, 1362, 233 Cal.Rptr. 923.)

“Such a contract has no existence whatever. It has no legal entity for any purpose and neither action nor inaction of a party to it can validate it …. ” (Colby v. Title Ins. And Trust Co. (1911) 160 Cal. 632, 644, 117 P. 913.) “If a purported assignment necessary to the chain by which the foreclosing entity claims that power is absolutely void, meaning of no legal force or effect whatsoever, [internal citations omitted] the foreclosing entity has acted without legal authority by pursuing a trustee’s sale, and such an unauthorized sale constitutes a wrongful foreclosure. (Yvanonova, supra, at pp. 855-856; citing Barrionuevo v. Chase Bank, N.A., at pp. 973-974.”
