Do I have to attend a Motion to Compel hearing for documents to be produced?

From your question, it sounds like you are representing yourself. When you are representing yourself, you are generally held to the same standard as an attorney. Attorneys are expected to attend Motion hearings, as should you.

While a routine or uncontested motion may not require an appearance, a Motion to Compel is usually NOT routine. Even if you supplied documents before the motion date, other issues may arise, which you certainly would want to address at the hearing. Failure to attend could result in negative consequences for your case.

It is possible you may be able to get the hearing rescheduled, but usually only if the other attorney agrees and the Judge is willing.
