one third of the contingency fee in the case on which they had worked. The Court had ruled that a lien attached to the fee and followed it into the hands of the supervisor, based upon "the familiar rule of equity that a contract to convey a specific object even before it is acquired will make the contractor a trustee as soon as he gets a title to the thing." The Court considered the "Acts of Third Parties" provision in the Sereboffs' ERISA plan analogous to the contingency fee claim, as the provision specifically identified a particular fund and a particular share of that fund to which Mid Atlantic was entitled. Under the rule of equity set forth in Barnes, Mid Atlantic could "follow a portion of the recovery into the Sereboffs' hands as soon as the settlement fund was identified, and impose on that portion a constructive trust or equitable lien."
