What happens if I Bill of Particular is delivered pass the due date assigned by the court?

Answer 1

The exact rules will vary from state to state and it may depend on how late the response is. Here in California, it is up to the parties to demand a Bill of Particulars. It's also up to the party making the demand to file a motion to compel compliance. If a tardy Bill of Particulars is served before a motion to compel is filed, then there are no consequences beyond a waiver of the right to raise any objections to the demand. The laws of your state may be different.
