Montana Rule of Civil Procedure Rule 11[E] provides that an attorney may help to draft a pleading, motion, or document filed by an otherwise self-represented person, and the attorney need not sign that pleading, motion or document.  The attorney in providing such drafting assistance may rely on the otherwise self-represented person's representation of facts, unless the attorney has reason to believe that such representations are false or materially insufficient, in which instance the attorney shall make an independent reasonable inquiry into the facts.

Montana Rule of Professional Conduct 1.2(c) provides that a lawyer may limit the scope of the representation if the limitation is reasonable under the circumstances and the client gives informed consent.

Montana Rules of Professional Conduct 6.5 provides that a lawyer who, under the auspices of a program sponsored by a nonprofit organization or court, provides short-term limited legal services to a client without expectation by either the lawyer or the client that the lawyer will provide continuing representation in the matter is subject to Rules 1.7 and 1.9(a) only if the lawyer knows that the representation of the client involves conflict of interest and is subject to Rule 1.10 only if the lawyer knows that that another lawyer associated with the lawyer in a law firm is disqualified by Rule 1.7 or 1.9(a) with respect to the matter.  Except as provided in paragraph (a)(2), Rule 1.10 is inapplicable to representation governed by Rule 6.5.
