Q: what does this mean having fully answered plaintiffs complaint prays that the demands of plaintiff be granted

A: I don't know since I have not seen the documents. If you do not have a lawyer I suggest that you get one.

Who are you? The plaintiff or the defendant? The phrase you typed makes no sense. Why would a defendant ask for plaintiff's complaint to be granted?

A lawsuit starts off with a complaint or possibly statement of claim if this is in magistrate's court. The person suing is the plaintiff. The complaint or statement of claim basically says to the court that the defendant done the plaintiff wrong in some way and the plaintiff asks for relief or money. At the end of the complaint/statement of claim is a clause usually beginning with "Wherefore" that says something like "wherefore plaintiff prays that the court .... award $x in damages and anything else the court deems proper." The defendant files an answer which should deny liability or wrongdoing and typically asks the court in the wherefore clause to dismiss the complaint and deny relief. However, it would depend on the kind of case it is - if the defendant admitted everything in the answer then a judgment is going to be entered against the defendant.

Sometimes there might be further pleadings. Perhaps the plaintiff has filed a motion for judgment on the pleadings or motion for summary judgment indicating that the complaint has been answered, defendant's answer does not amount to anything and that whatever the plaintiff is asking for should be granted.
