You seem to be so insistent on the statute of limitations requirement. Unfortunately, it is beyond reasonable dispute that for a non-judicial foreclosure, the statute of limitations is not four years. It's at least 10 years, and in many cases, 60 years. See Miller v. Provost (1994) 26 Cal.App.4th 1703.
That said, the California courts of appeal have uniformly agreed that a borrower has no standing to bring judicial action to stop a non-judicial foreclosure action before the date of the foreclosure sale. See, e.g., Keshtgar v. U.S. Bank, N.A. (2014) 226 Cal.App.4th 1201.
Consequently, the only means by which a borrower can use the courts to deal with a nonjudicial foreclosure, is after the foreclosure occurs; the borrower has standing to bring an action for damages against the foreclosing creditor, where the borrower alleges that the note and/or deed of trust or its assignment was void on the date of foreclosure sale. See Yvanova v. New Century Mortgage Corp. (2016) 62 Cal.4th 919.
I'm trying to be helpful here, so that you are not burdened by the statute of limitations issue. Hopefully, the cited case law above will help you understand why you cannot prevail on your current legal theory -- and, perhaps enable you to find another legal theory that will actually work for your case.
I hope I've answered your question. Please let me know if you require further clarification. And, please provide a positive feedback rating for my answer (click 3, 4 or 5 stars) -- otherwise, I receive nothing for my efforts in your behalf.
