A special note that, in most of the jurisdictions, the plaintiff can amend the complaint within the first 30 days from filing the complaint. You should always check the practice rules of the jurisdiction where you intend to file your complaint. Practice rules are statutory, you should be able to access to the types of motion available on internet involving a litigation in any particular jurisdiction.
After you file a motion, your opponent is allowed certain time limitation to reply to your motion in opposition/objection; you, then, have some limited time to respond/reply/rebut your opponent's objection. If your opponent wishes to rebut or to dispute your reply to his/her/its objection/opposition, he/she/it should file a "Motion for Leave to File Surreply". This type of procedural rules is the same in both Federal and state jurisdictions. Each state has her judicial litigant practice rules from the statutes. In some jurisdictions, party may be allowed to "supplement" additional filings to the motion/objection/reply already filed to submit additional relevant materials. Before you initiate a legal action or after receiving a Summons of being sued, it is essential to have access to the rules as reference whether you are represented by an attorney or by yourself.
There are arguable and non-arguable motions, for which we will discuss more later in this eBook. Although all motions are important, certain arguable motions can be makers or breakers. For instance, no party should take Motion to Dismiss and Motion for Summary Judgment (arguable motions) lightly. If judge grants the defendant's motion to dismiss (MTD) or the defendant's motion for summary judgment (MSJ), your case is over. However, you may file a motion for permission to amend your complaint to rephrase your allegation (Motion to Leave to Amend Complaint.), or a motion for reconsideration of judge's ruling to keep your case alive.
