John K. Haley, a real estate closing attorney in Buford, Ga., left work July 31 thinking the HomeBanc mortgages he’d closed earlier that day had cleared.

That turned out not to be true. Haley was one of dozens of Atlanta-area real estate closing attorneys who received bounced checks last month from HomeBanc Mortgage Corp. Lawyers estimate HomeBanc may have issued $20 million or more in bounced checks July 30 and July 31. HomeBanc filed for Chapter 11 bankruptcy protection Aug. 9.
