Permanent custody is what it states, it's permanent. Under Georgia custody law, if one or both of the parents tried to gain custody, it would be his/her burden to show the court why it should be changed. Georgia court follow the notion that stability is best for the child unless you can show that there is something in the environment that will adversely impact on the well being of the child.
Meaning the parents cannot just show that they have a home "as good" as yours, but better. They must show that there has been a substantial change in circumstances and that it is in the child's best interests to make the change and if the two homes are thought to be equal, then custody will stay as it is.
Let me know if I can be of further assistance
