Well, divorce is a process. You first serve divorce papers, and give the other side time to answer. Make sure that you have the waiver of service filed with the clerk. It has to be on file for 10 days. If they do not answer within the prescribed time, then you can move for a default judgment. In Texas (if that is where you are), the defendant has until the Monday following 20 days from service. This can get tricky, but if the petition was served on August 2, then you're certainly past that time.
You will then need to get the judge to sign a final order of divorce for the divorce to be final. To do this, you will need to file a motion for default judgment, a certificate of last known address, a service members affidavit, a TDH vital statistics form, a proposed order for the judge to sign, and have a court reporter lined up for the hearing. You can get all the forms at this site
. There are some instructions about what you need to do from there.
Once you have the hearing, and the judge signs the final order granting your divorce, then you are legally divorced.
I hope that helps. Good luck to you!
