Va. Code Ann. § 62.1-210

Any pledge made by the Authority shall be valid and binding from the time when the pledge is made. The revenue, money or property so pledged and thereafter received by the Authority shall immediately be subject to the lien of such a pledge without any physical delivery thereof or further act. Furthermore, 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 Authority, irrespective of whether the parties have notice of the pledge. No recording or filing of the resolution authorizing the issuance of bonds or credit enhancements, the trust indenture securing bonds or any other instrument, including filings under Title 8.9A (§ 8.9A-101 et seq.) of the Uniform Commercial Code of Virginia, shall be necessary to create or perfect any pledge or security interest granted by the Authority to secure any bonds or credit enhancements.
