Lewis Brisbois Bisgaard & Smith is fending off claims that its attorneys stole laptops from their previous firm containing sensitive client information, in a case that highlights the complications of what stays and what goes when lawyers jump ship.

Despite spending three hours before a magistrate judge on Feb. 27, Nelson Brown Hamilton & Krekstein, an insurance boutique, and Lewis Brisbois have been unable to reach a settlement. In May, what was then Nelson Levine de Luca & Hamilton sued to get the laptops back after 14 of its lawyers—who focus on data-security issues—left to open a Berwyn, Pennsylvania, office for Lewis Brisbois.
