Validity of pledges

Any pledge made by or pursuant to this part shall be valid and binding from the time when the pledge is made. Moneys pledged pursuant to this part and thereafter received shall immediately be subject to the lien of such pledge without any physical delivery thereof or further act, and the lien of any such pledge shall be valid and binding as against all parties having claims of any kind in tort, contract or otherwise against the state or the Treasurer or the municipalities irrespective of whether such parties have notice thereof. Neither the bond determination nor any other instrument by which a pledge is created need be recorded. Any such pledge made with respect to the moneys and investments in the Municipal Refunding Bond Escrow Fund for the benefit of the holders of the bonds for which the municipal refunding bonds are issued, except with the consent of the holders of such bonds, may be made irrevocable notwithstanding the discharge of the lien of any pledge and rights of the holders of special obligation bonds.
