N.Y. Civil Practice Law & Rules § 4017 (2026)

§ 4017. Objections. Formal exceptions to rulings of the court are
unnecessary.  At the time a ruling or order of the court is requested or
made a party shall make known the action which he requests the court to
take or, if he has not already indicated it, his objection to the action
of the court.  Failure to so make known objections, as prescribed in
this section or in section 4110-b, may restrict review upon appeal in
accordance with paragraphs three and four of subdivision (a) of section
5501.
