What type of attorney communications will California presume are in violation of the rules?

In California, express guarantees or warranties regarding the outcome of a legal matter are typically viewed as a violation of the Rules of Professional Conduct. This is because such guarantees can mislead clients about the nature and certainty of legal services. Legal outcomes are inherently uncertain and depend on numerous factors that are often beyond an attorney's control. As a result, making an express promise or guarantee implies predictable outcomes that can create unrealistic expectations for clients.

The essence of this rule is to maintain ethical boundaries and professionalism within the legal practice, ensuring that lawyers provide transparent communication without creating deceptive assurances. This safeguards both the integrity of the legal profession and the interests of clients who must make informed decisions without being led to believe that success is guaranteed.

The other options involve statements or actions that may be considered misleading or lacking clarity, but they do not carry the same presumption of violation as express guarantees or warranties. Statements about lawyer fees need to be clear; testimonials with disclaimers can be permissible under certain guidelines, and endorsements that mention potential outcomes can be ethically sound if framed appropriately. However, none of these implicate the same strong ethical presumptions against guarantees regarding legal results.
