Filing a clear Interrogatory Supplement Form preserves the responding party’s integrity, meets discovery duties, and limits motions to compel or sanctions. Accurate supplements reduce litigation risk by creating an auditable record and showing compliance with mandatory disclosure obligations.
The Interrogatory Supplement Form is used mainly by parties in civil litigation, their counsel, and litigation support teams to amend or expand prior interrogatory responses.
Use this form to document the update clearly, date the supplement, and follow service and verification steps required by local rules and the Federal Rules of Civil Procedure.
The individual or corporate representative whose answers are amended must sign or verify the supplement when a verification is required; counsel usually prepares and certifies the supplement per court rules and may attach exhibits or privilege logs.
Counsel signing the supplement certifies that the amendment is made in good faith, that reasonable inquiry was made to confirm facts, and that the submission complies with discovery rules such as FRCP 26(e) and any local court verification requirements.

Cite the original interrogatory by number, date served, and the page or paragraph being amended so readers can easily cross-reference the change.
Provide the corrected or supplemental narrative in plain language, indicating whether the response replaces or supplements the prior answer.
Attach documents, Bates ranges, or production references that substantiate the supplement; identify exhibits in the answer text for clarity.
If withholding material, include a brief privilege description and a privilege log reference consistent with local discovery obligations.
Include signature, printed name, title, and date; add attorney certification language when required by court rule or local practice.
