If you do not have an attorney then of course you need to appear. You should also explain to the judge then you never received any paperwork and found out about the hearing on the internet. You really need an attorney because your failure to provide this information could result in the dismissal of your case.

Generally the court will make a tenative ruling. If you are unsatisfied with the tenative ruling you will need to appear. Prior to a motion to compel, counsel are often required to "meet and confer' meaning that they need to contact each other and try to work out their discovery disputes. You need to prepare to argue why you should not have to provide the information they are requesting as well as the applicable law and legal reasoning behind the law. I would recommend finding an attorney who will fight for you. Best of luck.

A motion to compel is a step toward getting your case dismissed for failure to provide discovery. Your case has already been dismissed once. Now you don't have a lawyer. Without a lawyer, you don't stand a chance. Find yourself a lawyer or drop the case.

Did your old lawyers tell you why they were withdrawing from the case? The motion to compel is just the tip of the iceberg for you. I suspect that you also haven't hired expert witnesses that are likely required to prevail. For these reasons and more, I would discourage anyone from handling a medical malpractice claim on their own. That being said, call the Court and ask if it is an oral or a non-oral hearing. You will have to file an opposition to the motion. If you are past due, you will need to file a motion for additional time. You should also call the defense attorney (if you currently don't have an attorney) and try to work out the discovery dispute. Following Court deadlines and requirements is critical in all cases.
