Legal Question in Real Estate Law in California

If they foreclosed through a trustee's sale, nonjudicially, then it is no longer yours, and it belongs to either the lender who bid in at the sale, or a third party who purchased it at a sale.

If they foreclosed through a judicial foreclosure - rare, but not unheard of - then you technically have an interest subject to the right of redemption, and should keep it insured until the right to redeem expires and they get a sheriff's deed.

Mr. Roach is correct, but I suspect that what has actually occurred is that they sent to you a notice that they are going to foreclose but the sale has not yet happened so you stlll are the owner of the property. A notice is not the same as a sale.
