The specific outcome of any legal situation depends on the particular facts and controlling law of that situation. My answer here is for the purpose of general information about how the law works and is not intended to create an attorney client relationship between you and me. If you have any question regarding your legal rights and remedies, contact a lawyer personally.
As pointed out, you should start by contacting your attorney and maybe settingmupmamtime for a face to face meeting. If that does not work, you always have the right to terminate your attorney, take your file, and see another attorney.
The 60 day waiting period is for a divorce based on irreconcilable differences where the parties have agreed to all the terms. Even then it is a minimum waiting time before the court can hear the case, not a maximum time before they can act.
This answer does not constitute legal advice nor form an attorney client relationship. I am not your lawyer. If you have a legal issue in Tennessee you may contact me for a free consult.
You should set up a meeting with your attorney to talk about moving things along or else find a new one. If your ex has not find an answer to your counter-complaint, an attorney could file for a default judgement. He/she could also be filing a motion to compel answers to the interrogatories.
