Dallas’ Shamoun & Norman is suing former client Albert G. Hill Jr., alleging he failed to pay the firm a multimillion-dollar “performance incentive bonus,” but Hill alleges he never signed a contract agreeing to it.

In his March 15 motion to compel in Shamoun & Norman v. Albert G. Hill Jr., et al. , Hill — a wealthy businessman — seeks additional discovery from Dallas solo Frances Johnson Wright, his former personal lawyer, whom he alleges set up the bonus agreement with Shamoun & Norman without his consent. Wright is not a party to Hill.
