Amending Answers to Interrogatories
Rule 4:17- 7 requires that amended answers to interrogatories be served no later than 20 days prior to the end of the discovery period. Thereafter, amendments may be allowed only if the party seeking the amendments certifies that the facts on which the
amendment is based could not have been reasonably discoverable prior to the end of the discovery period. If a post-discovery end date amendment is made, the adversary may then make a motion, alleging exceptional circumstances, for additional discovery.
