Georgia Code Title 19. Domestic Relations § 19-9-132

(a) When a power of attorney delegates caregiving authority to a grandparent of a child, it may have an unlimited duration.

(b) Except as limited by or in conflict with federal law regarding the armed forces of the United States, a parent who is a member of the armed forces of the United States, including any reserve component thereof, or the commissioned corps of the National Oceanic and Atmospheric Administration or the Public Health Service of the United States Department of Health and Human Services detailed by proper authority for duty with the armed forces of the United States, or who is required to enter or serve in the active military service of the United States under a call or order of the President of the United States or to serve on state active duty, may delegate caregiving authority for a period longer than one year if such parent is deployed as defined in Code Section 19-9-6. Such term of delegation, however, shall not exceed the term of deployment plus 30 days.
