Some states require disclosure of legal malpractice coverage [really non-coverage.]  New York does not.  California is debating the issue.  From Law.Com:

"Deciding whether to require that attorneys tell clients when they don’t have malpractice insurance is proving extremely difficult for the California Bar Board of Governors.

After a confusing and contentious discussion Friday, board members unanimously punted a controversial proposed amendment back to agency staffers and the Committee on Regulation, Admissions and Discipline to discern whether it would fly legally.

The amendment would clarify when exactly lawyers would have to disclose their malpractice insurance status to clients, by linking disclosure with state Business and Professions Code §6147 and 6148. The codes require attorneys to draft written fee agreements for both contingency and non-contingency work that could cost clients more than $1,000. Exceptions include workers’ compensation cases and lawyers working for government agencies.

Based on his visibly irked reaction when the Board of Governors gave the amendment conceptual approval by a narrow 10-9 vote, State Bar President Jeffrey Bleich likely hopes the amendment will eventually get a thumbs down. He huffily denounced the proposed change as "problematic," saying it could allow attorneys to "commit a fraud" by insinuating they’re covered by malpractice insurance when in reality they aren’t. "
