South Dakota Multijurisdictional Practice (MJP)

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

South Dakota 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 South Dakota 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

South Dakota does not maintain a separate house-counsel registration program; out-of-state in-house counsel generally rely on RPC 5.5(d)(1). See the house counsel overview if linked from state navigation.
