Hello - first post here. I've been reading up on the threads in the last few days, and also AE's tweets.Also Calif doesn't muck around with divorces. She has failed to engage in the process so it is now a default divorce and could be finalised by Christmas. If she succeeds in stalling it might take a bit more than 12 months to finalise which could take it through til mid next year.
AE tweeted (and deleted?) the names of her lawyers/mediators a day or two ago, mentioning that she pays them monthly. So the negotions will be ongoing. One of the rules of collaborative divorce is that all involved are present at all meetings, I'd suppose at least IG, AE, their lawyers/mediators, with other professionals such as a children's advocate added as needed. So they can only negotiate when IG is back in the country. (AE also alluded to this in a tweet recently.)
Another rule of a collaborative divorce is that if AE or IG pull out, they don't get to keep their lawyers. They would have to get new lawyers and go to court to let a judge decide everything. (Or one of them does not get a new lawyer and does not engage and then there is a default judgement).
