This diversity action concerns a home foreclosure. Appellants, who are third parties to the assignment at issue, argue that Structured Asset Mortgage Investments II, Inc.’s (“SAMI”) assignment of the loan to the AR5 trust was defective because SAMI did so without proper endorsement of the Note or assignment of the deed of trust (“DOT”). Appellants further contend that such a defective transfer breached the governing terms of the Pooling and Servicing Agreement (“PSA”), and was thus ineffective.

We disagree. First, PSA violations such as failing to assign the DOT or endorsing the Note render a mortgage assignment voidable , not void . Saterbak v. JPMorgan Chase Bank, N.A. , 245 Cal. App. 4th 808, 815 (2016). Yvanova v. New Century Mortgage Corp. did not address whether “an assignment to a securitized trust made after the trust’s closing date is void or merely voidable,” 62 Cal. 4th 919, 941 (2016). But post- Yvanova California authority has consistently held that such an assignment is merely voidable. See, e.g. , Mendoza v. JPMorgan Chase Bank, N.A. , 6 Cal. App. 5th 802, 805 (2016); Yhudai v. Impac Funding Corp. , 1 Cal. App. 5th 1252, 1259 (2016); Saterbak , 245 Cal. App. 4th at 815. Nothing suggests that the California Supreme Court would hold to the contrary. Appellants therefore lack standing to contest the validity of loan assignments. Saterbak , 245 Cal. App. 4th at 815.

Second, Mortgage Electronic Registration Systems (“MERS”) was *3 empowered to assign its beneficial interest in the DOT to Wells Fargo, which could then instruct the trustee to initiate foreclosure proceedings. The plain language of the DOT confers upon MERS the right to act “as nominee for Lender and Lender’s successors and assigns”; MERS retains the express authority to act as historical nominee—no matter which entity becomes a successor on the loan. ^[1] Cervantes v. Countrywide Home Loans, Inc. , 656 F.3d 1034, 1042 (9th Cir. 2011); see also Cal. Civ. Code § 2924(a)(1).

Third, because Appellants did not raise any robosigning allegations in their opposition to the motion to dismiss, they have “effectively abandoned [their] claim, and cannot raise it on appeal.” Walsh v. Nev. Dep’t of Human Res. , 471 F.3d 1033, 1037 (9th Cir. 2006).

Finally, the securitization of Appellants’ loan and/or the DOT assignment are the bases for Appellants’ six causes of action. ^[2] Since these premises are unavailing, the district court properly dismissed Appellants’ complaint completely. Additionally, the district court properly denied Appellants leave to amend their complaint since “[a]ny amendment to [the] complaint would be futile.” Haskell v. Harris , 745 F.3d 1269, 1275 (9th Cir. 2014).

[1] Relatedly, we reject the arguments that there is no viable successor in interest to Appellants’ loan and that MERS’s absence on the note somehow obliterates its authority under the DOT.
