I have added Landlord / Tenant to your categories. Generally if a complaint is dismissed without prejudice, the complaint can be refiled if it is still within the statute of limitations. Good luck.

You should never delay seeking legal advice, disregard legal advice, or commence or discontinue any legal action because of information in this response.
As Ms. Allen has correctly pointed out, the "without" part of a dismissal without prejudice allows the plaintiff to re-file (as long as within the statute of limitations, of course). Further, in the event another lawsuit is filed in the future, I would highly recommend that you consult with an attorney. Best of luck to you.
