Ind. Code § 5-1-14-4

Sec. 4. (a) Notwithstanding any other law, a pledge of revenues or other money, or property made by any issuer is binding from the time the pledge is made. Revenues or other money, or property pledged and thereafter received by the issuer are immediately subject to the lien of the pledge without any further act, and the lien of a pledge is binding against all parties having claims of any kind in tort, contract, or otherwise against the issuer, regardless of whether the parties have notice of any lien. No resolution, ordinance, indenture, or any other instrument by which a pledge is created needs to be filed or recorded except in the records of the issuer.

(b) Notwithstanding any other law, an issuer may pledge any revenues or other money or pledge or mortgage property to pay debt service on or secure any obligations or any lease rental or contractual payments, if:

(1) the issuer has the necessary statutory authority to issue obligations, pay lease rentals, or make contractual payments for any project or purpose for which the pledge or mortgage is made;

(2) the revenues, money, or property is legally available, under federal, state, and local laws, to pay or secure debt service, lease rentals, or contractual payments; and

(3) the pledge or mortgage does not purport to create an obligation in violation of any statutory or constitutional limitation to which the issuer is subject.
