If you do not respond to a summons on, or before the scheduled hearing, you will receive a decision in the mail that finds you in violation of the charge, by default and you may have to pay a higher fine.
If you received a decision finding you in default, you have two options:
You may only request a new hearing once for each summons that is in default, subject to Section 6-21(e) of Title 48 of the Rules of the City of New York. The request must be submitted using the OATH-issued request form. The request can be submitted online or by mail. If the request for a new hearing is received by the OATH Hearings Division within 60 days of the date of the missed hearing date, then OATH will grant the request.
Read the Rules governing missed hearings and default decisions.
