An Atlanta law firm has sued to shut down an apparently phony firm with an almost identical name that lists a nonexistent address—two, actually—in downtown’s Hurt Building as its office in records with the Georgia Secretary of State.

A complaint filed by Shapiro Pendergast & Hasty LLP said that someone registered a company named Shapiro Pendergast & Hasty LLLP—tossing in an extra “L”—with the state in October. The filing says the company is a “limited liability limited partnership.”
