If she refuses
mediation, then normally Court is the only other option to get things sorted, so its kind of a positive that she is willing to do Collaborative Lawyers.
I think until you have exchanged
financial disclosure your CL may not be able to give you any indication on what the split may be.
In a way they are right saying not to have any pre-conceived ideas about the split as this may give you a firm ''stance'' which could be difficult to move from.
Remember her CL will be probably saying the same thing to her!
In the article link I posted, it states that if the Collaboration does not work, then these lawyers can not represent you in Court.
You can''t force her to do
mediation and Court is an expensive option that a Judge will impose a decision, so there is a possibility neither of you will be happy about it and will have spent a chunk of money to get. So if I were you I''d give CL a go.
Hopefully with full
financial disclosure, you''ll all be able to negotiate a split that you both will be happy with.
