When my law partner (Not life partner) left another firm to start our own practice, a letter was sent to every client letting them know of the change. It said you have the option of remaining with the current firm or switching your file to the new firm. If they switched, we paid the old firm a referral fee when the case settled.
As for Junior, I was hoping to see his venture make it. Sr. is off his freakin' rocker. He used to just come in and hammer Jr. and everyone in there for trivial stuff, trying to start fights. At first I thought it was all for the sake of the "reality" show. But with Jr. leaving and the ensuing court battles, I think Sr. really is crazy in the head.
