Common questions
Frequently Asked
4
When does a representation become prohibited by law under the conflict rules?+
A representation is prohibited by law when a statute or other positive law forbids the lawyer from proceeding even with client consent. Rule 1.7(b)(2) removes such conflicts from the consent option entirely.
Does an unlawful purpose automatically terminate a trust?+
Yes. Under Uniform Trust Code § 410(a), a trust ends to the extent its purposes have become unlawful, contrary to public policy, or impossible to achieve.
How does the phrase affect a judge's extrajudicial activities?+
A judge may engage in extrajudicial activities only when they are not prohibited by law or the Code. Conduct that violates another statute therefore falls outside the permitted category.
What consequence follows when a contract term is prohibited by law?+
Courts prefer an interpretation that gives every term a reasonable, lawful, and effective meaning over one that would leave part of the agreement unlawful or without effect.
