Pennsylvania Multijurisdictional Practice (MJP)
Pennsylvania Rules of Professional Conduct and Rule 8.5 address unauthorized and multijurisdictional practice. See the MJP hub for general background.
Pennsylvania Rule 5.5 generally tracks ABA Model Rule 5.5. Substantial in-state employer practice requires a Rule 302 limited license.
Temporary practice
Temporary services under Rule 5.5(c) may be permitted when requirements are met. Court appearances remain subject to pro hac vice.
