The prohibition against aiding clients in carrying out crimes and frauds has been in the news lately, in connection with the quandary that lawyers find themselves in when attempting to help clients in the marijuana industry — whose conduct may be legal under state law, while remaining illegal under federal law. (We’ve blogged about it previously, here and here. ) In this environment, it is useful to consider just what constitutes assisting a client’s crime or fraud, as the Ohio Supreme Court did last week in disbarring a lawyer who helped a divorce client hide assets from her spouse.

Under your jurisdiction’s version of Model Rule 3.4(d), you have an ethics duty to make reasonably diligent efforts to comply with legally proper discovery requests. Interpreting a wrinkle in Ohio’s version of the rule, the state supreme court held earlier this month that a violation requires “intentionally or habitually” flouting the requirement — and in an odd twist, the court held that a claimed Vitamin D deficiency did not excuse a Dayton lawyer’s failure to obey.

What should you do when you are co-counsel on a case or in a deal, and you become aware that the other lawyer has made an error? A new ethics opinion from the New York State Bar Association says that if you reasonably believe that your co-counsel has committed a significant error or omission that may give rise to a malpractice claim, you must disclose the information to the client.

Some ethics violations happen because a lawyer carefully analyzes a debatable situation and draws a good-faith, but incorrect, conclusion. And then there are the lawyers who leave me wondering. Let’s say your divorce client hacks into his future-former-wife’s e-mail account and hands you her payroll information and the direct examination questions that her lawyer has e-mailed her in preparation for trial. Raise your hand if you think you can use that evidence.

Courts often analyze motions to disqualify by balancing the need to uphold professional standards against the rights of clients to choose their lawyers freely. The New Jersey court of appeals struck that balance earlier this month in upholding the disqualification of a lawyer who violated a confidentiality order, finding that the lawyer knowingly disobeyed a court order, among other violations.

Business DeterminationThe leak of millions of documents apparently hacked from Panama-based law firm Mossack Fonesca has exposed the tax strategies of some of the world’s elite.  But the Panama Papers also shine a light on some failures of Mossack Fonesca to screen out problematic clients — failures of due diligence that the firm itself recognized.
