Ala. Code § 11-50-100: Payment and Redemption of Bonds Generally.

The bonds issued under this division shall be payable in from 10 years to 15 years from their date as determined by the council, but any bond or bonds so issued and sold shall, at the option of the city or town, be payable at any interest period.

In the event the city or town should elect to pay off any such bond or bonds before maturity, it shall pay as a bonus to the holder thereof a sum equal to one-fourth the annual interest thereon, and the city or town shall give public notice of its intention to redeem said bond or bonds, describing the same by number and series, by publication once a week for three successive weeks in a newspaper published in said city or town or of general circulation therein; and, if said bonds are registered, such notice shall also be sent by registered or certified mail to the address of the registered owner thereof where such address is shown on the book of registration.
