The Georgia Code defines a 'legal custodian' as a person to whom legal custody has been given by court order and who has the right to physical custody of the child and to determine the nature of the care and treatment of the child and the duty to provide for the care, protection, training, and education and the physical, mental, and moral welfare of the child. O.C.G.A. § 15-11-43, Code 1933, § 24A-2901. A legal custodian does not have the right to consent to the adoption of a child, as this right is specifically retained by one with greater rights over the child, a child's parent or guardian. O.C.G.A. § 15-11-43, Code 1933, § 24A-2901 (rights of a legal custodian are subject to the remaining rights and duties of the child's parents or guardian); Skipper v. Smith, 239 Ga. 854 (238 S.E.2d 917) (1977) (right to consent to adoption is a residual right retained by a parent notwithstanding the transfer of legal custody of the child to another person); Jackson v. Anglin, 193 Ga. 737, 738 (19 S.E.2d 914) (1942) (parent retains exclusive authority to consent to adoption although child is placed in temporary custody of another);
