California Code, Government Code - GOV § 53595.35

(a) In the discretion of the legislative body of a local agency, any debt instruments issued under this article may be secured by an indenture by and between the local agency and a corporate trustee or trustees, which may be any trust company or bank having the powers of a trust company within or without the state. The indenture or resolution providing for the issuance of the debt instruments may pledge or assign the tax increment revenues or the interest of the local agency therein. The indenture may contain provisions for protecting and enforcing the rights and remedies of the holders of debt instruments as may be reasonable and proper and not in violation of law, including particular provisions specifically authorized by law to be included in any indenture of the local agency authorizing debt instruments pursuant to this article. The indenture may set forth the rights and remedies of the holders of debt instruments and of the trustee or trustees, and may restrict rights of action of holders of debt instruments. In addition to the foregoing, the indenture may contain other provisions as the local agency may deem necessary or desirable to facilitate the issuance and sale of the debt instruments or for the protection and security of the holders of debt instruments.

(b) Any holder of debt instruments issued under this article or any of the coupons appertaining thereto, and the trustee or trustees under any indenture, except to the extent the rights herein given may be restricted by any indenture securing the debt instruments, may, either at law or in equity, by suit, action, mandamus, or other proceeding, protect and enforce any and all rights under the laws of the state or granted by this article or under indenture, and may enforce and compel the performance of all duties required by this article or by the indenture to be performed by the local agency or by any officer, employee, or agent thereof.
