Idaho Appellate Rule 11.2. Signing of Notice of Appeals, Petitions, Motions, Briefs and Other Papers; Sanctions.
(a) Every notice of appeal, petition, motion, brief and other document of a party represented by an attorney shall be signed by at least one (1) licensed attorney of record of the state of Idaho, in the attorney's individual name, whose address shall be stated before the same may be filed. A party who is not represented by an attorney shall sign the notice of appeal, petition, motion, brief or other document and state the party's address. The signature of an attorney or party constitutes a certificate that the attorney or party has read the notice of appeal, petition, motion, brief or other document; that to the best of the signer's knowledge, information, and belief after reasonable inquiry it is well grounded in fact and is warranted by existing law or a good faith argument for the extension, modification, or reversal of existing law, and that it is not interposed for any improper purpose, such as to harass or to cause unnecessary delay or needless increase in the cost of litigation. If the notice of appeal, petition, motion, brief, or other document is signed in violation of this rule, the court, upon motion or upon its own initiative, shall impose upon the person who signed it, a represented party, or both, an appropriate sanction, which may include an order to pay to the other party or parties the amount of the reasonable expenses incurred because of the filing of the notice of appeal, petition, motion, brief or other document including a reasonable attorney's fee.
(b) The court may declare a party a vexatious litigant pursuant to Idaho Court Administrative Rule 59.
