(a) A custodian, acting in a custodial capacity, has all the rights, powers, and authority over custodial property that adult owners have over their own property, but a custodian may exercise those rights, powers, and authority in that capacity only. (b) This Code section does not relieve a custodian from liability for breach of Code Section 44-5-122. (Code 1981, § 44-5-123, enacted by Ga. L. 1990, p. 667, § 1.)
