As a condition of eligibility for aid, each recipient of aid to families with dependent children shall be deemed, by accepting aid, to have made an assignment to the department of the right to any support owed up to the amount of aid paid by the department to the recipient in her own behalf or in behalf of any other person for whom the recipient is receiving aid.

The department shall be subrogated to the right of such child or recipients or the person having custody to collect and receive all child support payments and to initiate any support action existing now or in the future under the laws of Alabama.
