Can i living in georgia contest a divorce filed in texas without an attorney
Certainly!
But you must be cautious of the consequences of submitting yourself to the personal jurisdiction of the Texas court. Because unless you were personal served with process in the state of Texas that court's authority is limited to granting or denying dissolution of the marriage; disposition of marital property situated within the state and the custody placement of any minor children residing in Texas.
Any filing by you or your attorney in that lawsuit, other than to quash service of process, whether you appear in person or not, will submit your person to the court's jurisdiction and could result in the entry of orders that may not be to your liking.
