John Frohling, a lawyer for half a century, most of it in municipal bond work, no doubt regrets his brief foray into real estate practice. He and his firm were used to facilitate three fraudulent house-flipping deals, leading to ethics charges and a censure recommendation.

Frohling represented both buyers and sellers in each of the deals, despite their conflicting interests, and also failed to properly supervise the paralegal who did the paperwork, the Disciplinary Review Board said in an Oct. 14 presentment to the New Jersey Supreme Court.
