Article 9 of the Uniform Commercial Code prescribes a statutory framework governing the foreclosure process for security interests in personal property. The default provisions of Chapter 6 of the Revised Uniform Commercial Code (Section 9-601 through 9-629) set forth these security interests. As a secured creditor, you need to determine the best and safest way to sell the assets: public sale, private sale or accepting the collateral as partial or full satisfaction of the debt (UCC 9-610, 9-621-9-623). If you choose either of the first two options, you need to determine who should conduct the sale, how it should be advertised, whether a landlord waiver exists, etc. The norm is to employ a professional such as an auctioneer. When selling to former insiders or management of the debtor privately, take extra care to avoid challenges and claims of bad faith, fraudulent conveyance, etc. Having a fiduciary such as an assignee for the benefit of creditors act as the "sales agent" of the secured party, may insulate the secured party and substantially reduce the exposure to a successful challenge to the disposition.

I am not licensed to practice in California, but any good California lawyer should be able to guide you through the process of enforcing your security interest in the collateral secured by the Security Agreement and UCC-1. I would suggest you contact an attorney in your area as soon as possible so that the value of your collateral is not impaired or dissipated.

There are many factors to consider in determining if you have a valid security interest in the business collateral. You may have a signed U.C.C. statement, but, was it executed properly, was it filed, was the lien "perfected?" If any of things were not done in accordance with the laws governing secured transaction, you may not have a lien at all, or your interest may be subordinated to someone else's. You should contact a lawyer in your area to find out.
