A family law attorney has a very busy practice. She spends considerable time preparing for and in several court appearances each week, and she spends much of the rest of her time meeting with new clients and supervising paralegals and associates on various aspects of each case. Many of her clients complain, however, that she does not return telephone calls and the paralegals and associates often take calls from clients who are dissatisfied with the attorney’s failure to return telephone calls. Finally, one of her clients files a bar complaint. Is the attorney subject to discipline for failure to return telephone calls?
