This new article by Mary Radford looks at common ethics issues arising in classic "Main Street" practice, where the lawyer may end up representing multiple family members and family businesses. The artice is quite useful if you teach PR, you don't have much experience in this area of legal ethics, and you want to highlight some of these issues. Btw, Radford cites the ACTEC commentaries on the Model Rules, which are another great resource. You often hear the argument that "we can't have separate rules for each legal speciality." Lawyers doing trusts and estates have had their own gloss, if not their own version of the rules, for many years.
