Georgia Code Title 13. Contracts § 13-3-20

(a) Generally the contract of a minor is voidable. If in a contractual transaction a minor receives property or other valuable consideration and, after arrival at the age of 18, retains possession of such property or continues to enjoy the benefit of such other valuable consideration, the minor shall have thereby ratified or affirmed the contract and it shall be binding on him or her. Such contractual transaction shall also be binding upon any minor who becomes emancipated by operation of law or pursuant to Article 10 of Chapter 11 of Title 15.

(b) The contract of a minor for necessaries shall be binding on the minor as if the minor were 18 years of age except that the party furnishing them to the minor shall prove that the parent or guardian of such minor had failed or refused to supply sufficient necessaries for the minor, that the minor was emancipated by operation of law, or the minor was emancipated pursuant to Article 10 of Chapter 11 of Title 15.
