Montana Multijurisdictional Practice (MJP)

Montana Rules of Professional Conduct and Rule 8.5 address unauthorized and multijurisdictional practice. See the MJP hub for general background.

Montana Rule 5.5 generally tracks ABA Model Rule 5.5, including temporary practice under 5.5(c) and the house-counsel safe harbor under 5.5(d)(1).

Temporary practice

Temporary services under Rule 5.5(c) typically include association with Montana counsel, tribunal-related work with authorization, ADR related to the lawyer’s home practice, and other services reasonably related to practice where admitted. Court appearances remain subject to pro hac vice.

House counsel

Montana has no separate house-counsel registration; see RPC 5.5(d)(1).
