Whyme?: Thank you for sharing your experience. My spouse has misgivings about seeing a mediator and prefers a court solution. It was only last night that she agreed to try the approach for reasons you and others listed. Consequently, today I put a call into a mediator, who I'm told, is low key yet firm. I'm "hoping" to avoid my spouse feeling pushed or trapped and then walking away.
In terms of settlement topics I'm trying to go after some easy wins for us both. Up to now that hasn't worked. Instead, spouse wants agreement first on my buying her share of the matrimonial home and matching that amount with cash. My answer is no. I see an issue like the home as part of a package agreement. So thanks for the good luck.
A court solution is a last resort, for two people who have been unable to reach an agreement themselves. It is also expensive! If your ex wants to jump right to court, she either misunderstands the process, or has no intention of ever agreeing to anything you suggest.
First, try talking and sorting it out yourselves.
Second, try mediation, and get a neutral professional to help you collaborate to sort it out yourselves.
Last, take the fight (because it's become one at that point) to court and let the judge sort it out.
Ask your ex if she wants to divide your stuff up between the two of you, or spend a ton of money on lawyers and court to divide up the remnants.
And yes, you might take a preliminary visit to the mediator to get a list of all the financial information required, and have to come back later, or you could gather all the financial information now and then go in prepared.
The main problem with separation negotiations is that they come hot on the heels of a relationship breakdown and emotions are running high.
And angry people want to go to court because they expect to see justice done for perceived wrongs during the relationship breakdown, when all family court gives is equal division of assets. It doesn't find anybody at fault or compensate the person who feels they are the victim.
Think about how the relationship ended, and you may be able to develop some insight into why your ex wants what she wants, why she dreams that court would give it to her but a mediator wouldn't, etc, and that will help you negotiate with her better.
