Any resolution of the board of directors, or trust indenture, under which bonds may be issued pursuant to this article may contain provisions creating a statutory mortgage lien, in favor of the holders of such bonds and of the interest coupons applicable thereto, on the facilities and other property, including any after-acquired property, out of the revenues from which such bonds are made payable. The resolution of the board of directors, or the trust indenture, may provide for the filing for record in the office of the Judge of Probate of Fayette County of a notice containing a brief description of such facilities or other property, a brief description of such bonds, and a declaration that the statutory mortgage lien has been created for the benefit of the holders of such bonds and the interest coupons applicable thereto, upon such facilities and other property, including any additions thereto and extensions thereof. The judge of probate shall receive, record, and index any such notice filed for record in his or her office. The recording of such notice, as herein provided, shall operate as constructive notice of the contents thereof.
