Plain-English Summary
Every pleading, motion, or other filed document needs a signature — from an attorney of record or, if no attorney is involved, from the party personally. Electronic filings follow the signature rules in ACJA § 1-901, and when a filing needs more than one signature, such as a stipulation, a person may sign for someone else only with that person’s actual authority, documented either by an attached authorization or by an “/s/ [name] with permission” notation. A court must strike an unsigned document unless the omission is promptly fixed once someone points it out.
By signing, the attorney or party certifies — after a reasonable inquiry — that the filing is not being used to harass or run up costs, that its legal positions are grounded in existing law or a good faith argument to change it, and that its factual claims and denials have or will likely have evidentiary support.
A court may sanction whoever signed a document that violates these certifications, or a party who does not participate in good faith in the required pre-motion consultation. But before moving for sanctions, the requesting party must first try to resolve the issue through a good faith consultation, then give written notice of the specific violation; only if the other side does not withdraw or correct the problem within 10 days may a sanctions motion follow, and that motion must be separate from any other motion and come with its own consultation certificate.
An attorney may help draft filings for someone who is otherwise representing themselves without signing the document or taking on full representation, relying on that person’s account of the facts unless there’s reason to doubt it — in which case the attorney must independently look into the facts.
