Collaborative practice doesn't favor one style of client or exclude others. While it's theoretically hospitable to all clients, clients with severe psychological or personality disorders, and cases involving a history of force, could also be deemed inappropriate for using collaborative processes. The collaboratively trained lawyer has their first interview with a client in a very different manner to a lawyer in a traditional lawyer-directed negotiation or litigation.
The primary interview is dubbed as a "process" interview, within which all the methods of achieving settlement are discussed and evaluated with the client. A Collaborative Lawyer is trained to screen a client in or out of the method. If it turns out clear that the client, or their former partner, is unfit to the collaborative process, then the lawyer is in a position to change gears and alter the content of the interview.
