In Georgia, the divorce is final on the day it's filed by the clerk. Not the day the judge signs it. My divorce was signed by the judge on August 27th, but not filed in the clerks office until September 9th. So, from August 27th until September 9th it wasn't really "final". And this was in Georgia as well.

*** CODE SECTION *** 12/03/01
31-10-22.
(a) A record of each divorce, dissolution of marriage, or annulment granted by any court of competent jurisdiction in this state shall be filed by the clerk of the court with the department and shall be registered if it has been completed and filed in accordance with this Code section. The record shall be prepared by the petitioner or the petitioner's legal representative on a form prescribed and furnished by the state registrar and shall be presented to the clerk of the court with the petition. In all cases, the completed record shall be a prerequisite to the granting of the final decree.
In other words, the "completed record" (which includes the judgement, and the filing of the judgement) is a prerequisite to the granting of the final decree. It's not actually "granted" until it's filed.
In Tennesse, to get married again, you just have to have a copy of the divorce decree. There's no set waiting period between when you were divorced and when you can re-marry, as there is in some states. (Here in Missouri you have to wait 30 days between the time your divorce was final and the time you apply for a marriage license). In Georgia, if divorced within six months prior to the marriage license application you will need to show a copy of your divorce decree.
