La. Public Health and Safety § 40:600.95
Any pledge made by the corporation shall be valid and binding from the time when the pledge is made. The money, assets, or revenues of the corporation so pledged and thereafter received by the corporation 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 corporation, irrespective of whether such parties have notice thereof. Neither the resolution nor any other instrument by which a pledge is created need be recorded or filed in order to establish and perfect a lien or security interest in the property so pledged.
