Legal Question in Credit and Debt Law in California

The UCC has no provisions for discharge of a bank loan that I know of. Debts are only discharged in Bankruptcy Court. Like any other contract, breaches of bank loan agreements, including failure to pay when due, are subject to a four-year statute of limitations, but that is not a UCC provision and it does not discharge the debt, it merely makes it unenforceable in a court proceeding.
