The question mark is underused. Many times, you can make a legal issue simpler and pithier by presenting it in the form of a question. It’s easy surgery:
This motion asks the Court to consider whether
the statute of limitations is tolled by the fact that
the defendant signed a waiver.
Does the defendant’s signed waiver toll
the statute of limitations?
The exclamation point is overused. Give yourself a budget of one exclamation point for any document longer than three pages. If you must use it, use it wisely.
