Ala. Code § 45-27-244.04: Return of Application.

When an application is returned to the judge of probate unsigned, or when less than the correct amount of the taxes and fees due therefor has been paid, due to a change of address or other cause, such application shall be returned to the applicant for signature or correction. A return of such application or remittance shall not, however, extend the time required by law for such taxes to be paid or such tag or decal to be secured. If more than the correct amount of taxes and fees is received, the judge of probate shall retain the correct amount and return the excess together with the motor vehicle tag or decal.
