"Lawyers admitted to multiple jurisdictions may be subject to different ethical requirements in the different states in which they are licensed to practice law, according to a new ABA ethics opinion.

A March 1 ethics opinion from the ABA’s Standing Committee on Ethics and Professional Responsibility provides a comprehensive analysis of which jurisdiction generally controls in these instances.
