A Montgomery County attorney was disbarred Tuesday by the state Supreme Court for his role in several estate-planning companies that had nonlawyers drafting trusts for the elderly.

The Disciplinary Board of the Pennsylvania Supreme Court determined after nine days of hearings that attorney Brett Weinstein of King of Prussia, Pa., had violated several Rules of Professional Conduct by having little if any contact with clients of several estate-planning businesses who were assisted in drafting trusts by nonlawyer employees of the companies associated with Weinstein’s law office.
