According to the Federal Rules of Civil Procedure, the plaintiff must initiate a conference between the parties after the complaint was served to the defendants, to plan for the discovery process. The parties should attempt to agree on the proposed discovery schedule, and submit a proposed Discovery Plan to the court within 14 days after the conference. After that, the main discovery process begins which includes: initial disclosures, depositions, interrogatories, request for admissions (RFA) and request for production of documents (RFP). In most federal district courts, the formal requests for interrogatories, request for admissions and request for production are exchanged between the parties and not filed with the court. Parties, however, can file motion to compel discovery if responses are not received within the FRCP time limit. Parties can file a motion for a protective order if the discovery requests become unduly burdensome or for purpose of harassment.
