Cal. Gov. Code § 57477

Except as otherwise provided in this division, consolidation does not affect any debts, demands, liabilities, or obligations of any kind existing in favor of or against the cities consolidated at the time of consolidation. Consolidation does not affect any pending action or proceeding involving any such debt, demand, liability, or obligation or any action or proceedings brought by or against any city prior to consolidation. The proceedings shall be continued and concluded by final judgment or otherwise as if consolidation had not been effected. Those rights or liabilities are the rights and liabilities of the successor city.
