S.D.N.Y. Local Civil Rule 33.3

(a) Unless ordered otherwise by the court, at the commencement of discovery,

interrogatories will be restricted to those seeking names of witnesses with

knowledge of information relevant to the subject matter of the action, the

computation of each category of damage alleged, and the existence, custodian,

location, and general description of relevant documents, including pertinent

insurance agreements, and other physical evidence, or information of a similar

nature.

(b) During discovery, interrogatories other than those seeking information described

in paragraph (a) above may only be served only

(1) if they are a more practical method of obtaining the information sought than

a request for production or a deposition, or

(2) if ordered by the court.

(c) At the conclusion of other discovery, and at least 30 days before the discovery cut-off date, interrogatories seeking the claims and contentions of the opposing party

may be served unless the court has ordered otherwise.
