A longtime international attorney facing multistate discipline was unanimously disbarred by the Maryland Appeals Court last week after he was found to have repeatedly commingled client and personal funds, leading to frequent negative balances in his attorney trust account.

Lawrence Daniel O’Neill—an attorney who had more than 45 years experience providing consulting services to international corporations—also failed to maintain accurate accounts of client funds and intentionally made false statements to Maryland disciplinary investigators, according to the opinion filed Wednesday. O’Neill maintained an office in New York, but he was licensed to practice in Maryland, the District of Columbia, and Ireland.
