These are the filings that drive a lawsuit through the system: complaints, answers, motions, briefs, discovery requests and responses, and post-judgment papers. Each has its own format requirements under federal and state procedural rules, and each has a deadline that cannot be missed without consequences. Clean, procedurally correct filings move a case forward; sloppy ones invite motions to strike, amended responses, and avoidable delays.
