What the role means at a US firm
A practice group move, or team lift-out, is a group of lawyers moving together from one firm to another. It might be one partner with the associates and professional staff who work with that partner, or an entire practice group of several partners. For a firm of 5 to 200 attorneys, a group move is often the fastest way to open a new practice area or to double down on one.
It is also a different kind of hire from a lateral partner. The firm is not evaluating a person. It is evaluating a team, its clients, its economics, and the effect on the firm it joins.
