N.Y. Comp. Codes R. & Regs. tit. 20, § 3000.11
(a) General.
(2) The fact that any matter may have been obtained through any other authorized procedure is not a ground for omitting such matter from the stipulation. Such other procedures should be regarded as aids to stipulation, and matter obtained through them, which is within the scope of paragraph (1) of this subdivision, must be set forth comprehensively in the stipulation, in logical order in the context of all other provisions of the stipulation.
(b) Form.
Stipulations shall be in writing, signed by the parties thereto or by their representative, and shall be filed with the supervising administrative law judge in duplicate. Only one set of exhibits shall be required. Documents or other papers, which are the subject of stipulation in any respect and which the parties intend to place before the Division of Tax Appeals, shall be annexed to or filed with the stipulation. The stipulation shall be clear and concise. Separate items shall be stated in separate paragraphs, and shall be appropriately numbered. Exhibits attached to a stipulation shall be lettered serially.
(c) Filing.
Executed stipulations prepared pursuant to this subdivision, and related exhibits, shall be filed by the parties with the supervising administrative law judge, at or before commencement of the hearing of the controversy, unless the supervising administrative law judge shall otherwise specify. A stipulation, when filed, need not be offered formally to be considered in evidence.
(d) Objections.
Any objection to all or any part of a stipulation should be noted in the stipulation, but the administrative law judge or presiding officer will consider any objection to a stipulated matter made at the commencement of the hearing or for good cause shown, made during the hearing.
(e) Binding effect.
A stipulation shall be treated, to the extent of its terms, as a conclusive admission by the parties to the stipulation, unless otherwise permitted by the tribunal, administrative law judge or presiding officer, or agreed upon by the parties. The tribunal, administrative law judge or presiding officer will not permit a party to a stipulation to qualify, change or contradict a stipulation in whole or in part, except where justice requires. A stipulation and the admissions therein shall be binding and have effect only in the pending proceeding and not for any other purpose, and cannot be used against any of the parties thereto in any other proceeding.
(f) Noncompliance by a party.
(1) Motion to compel stipulation. If, at the date of issuance of a hearing notice in a controversy, a party has refused or failed to confer with his or her adversary with respect to entering into a stipulation in accordance with this section, or has refused or failed to make a stipulation of any matter within the terms of this section, the party proposing to stipulate may, within 90 days of service of the proposed stipulation, make a motion to the tribunal, on notice to the other party or representative, if any, for an order directing that the matters covered in the motion should be deemed admitted for the purposes of the hearing. The motion shall be filed with the supervising administrative law judge and shall:
