Partners, and lawyers who alone or with others hold comparable managerial authority in a firm, must take reasonable steps to have arrangements in place that give reasonable confidence every lawyer in the firm follows the rules; a lawyer who directly supervises another lawyer must take reasonable steps to see that lawyer complies. A lawyer is answerable for another lawyer's breach where the lawyer ordered it or knowingly ratified it, or where, as a partner, manager or direct supervisor, the lawyer learned of it while the consequences could still be avoided or lessened and failed to take reasonable remedial action.
