Under NY CPLR § 3130, to formally object to an interrogatory, you provide a written response specifying the grounds for your objection. Any party may serve written interrogatories on any other party.Interrogatories are limited to 25 in number, including subparts, unless another limit is specified in the preliminary conference order. Interrogatories are a discovery tool (among many) used in lawsuits in New York courts. In sum, these are written questions seeking specific information. In many civil actions, before the case is resolved there takes place a process known as pretrial discovery. This summary describes this process. After commencement of an action, any party may serve written interrogatories upon any other party. Here are some sample interrogatory objections, a cheat sheet that might help you determine how to object to interrogatories. Any ground not stated in a timely objection is waived unless the court, for good cause, excuses the failure.
