Ala. Code §§ 26-11-2; 26-17-6; 26-17-22
A father of a nonmarital child may seek to legitimate the child and render him or her capable of inheriting his estate by filing a notice of declaration of legitimation in writing attested by two witnesses, setting forth the name of the child, supposed age, and the name of mother, and stating that he thereby recognizes him or her as his child and capable of inheriting his estate, real and personal, as if born in wedlock.
A child, a child's natural mother, or a man presumed to be the child's father under § 26-17-5(a) may bring an action at any time for the purpose of declaring the existence of the father and child relationship. For purposes of support, the action shall be brought before the child reaches age 19.
The natural mother and father of a child born to a woman who was unmarried at the time of birth and had not been married or attempted to be married within 300 days prior to the birth may, at any time prior to the child's 19th birthday, state and acknowledge that they are the natural parents of the child in an affidavit of paternity signed by both parties before a notary public. The affidavit of paternity shall be a legally sufficient basis for establishing an obligation for child support and for the expenses of the mother's pregnancy and confinement. The affidavit may be admitted as evidence of paternity in any action to establish a support order or an adjudication of paternity.
Ala. Code § 26-10C-1
A person filing a notice of intent to claim paternity of a child or an acknowledgment of paternity [with the putative father registry] shall include all of the following:

The putative father may file his notice of intent to claim paternity prior to the birth of the child.

A person who has filed a notice of intent to claim paternity may at any time revoke a notice of intent to claim paternity previously filed and, upon receipt of the notification by the registry, the revoked notice of intent to claim paternity shall be deemed a nullity nunc pro tunc.
Ala. Code § 26-10C-1(f)
The Department of Human Resources shall, upon request, provide the names and addresses of persons listed with the registry to any court. The information shall not be divulged to any other person except upon order of a court for good cause shown.

When the court handling the adoption receives said notice of the intent to claim paternity, that court shall forthwith give notice of the pendency of the adoption proceeding to the putative father, and additionally notify the biological mother that the putative father has registered in conformity with the putative father registry.
