Does that mean it will be final then if the judge scheduled two hearings back to back?

You divorce could be final at the August hearing IF the two of you come to an agreement on all matters - including the custody and placement of your daughter, and division of assets, debts, and support matters. If you both are not able to reach an agreement, then the September date is your 'trial' date where the judge will expect each of you to testify and present exhibits and any other witnesses for evidence into the record. The judge will then make a decision on all the items that the two of you continue to dispute. If you can reach agreements on all matters except one, then you would want to turn in a signed agreement for all of those matters, and ask the court to just rule (make orders) on the final item that is in dispute. Hopefully you each have an attorney. If not, you should at least meet with an attorney to review and prepare for your hearings.
