What is Collaborative Family Law (CFL)?

Hello, I need some assistance on these guiding questions. Thank you in advance! What is Collaborative Family Law (CFL)? How did CFL evolve? What is the history of CFL?
How is this process different from other ADR(Alternative dispute resolution ) that we have learned about?
Under what circumstances would CFL be appropriate? When would it be inappropriate?
Imagine you are a family lawyer in Alberta – would you offer CFL to your clients? Explain.
