Discovery is one of the most important aspects of litigating a case. If you aren't sure how to respond to something as basic as this, its a sure sign that you are in over your head in litigation.

If the case is important enough to litigate, its important enough to make whatever sacrifice necessary to hire a lawyer. If you wont and cant hire counsel, you need to rethink using the courts as a means of resolving your dispute before something terrible happens.
