Knowing my STBX and her nasty and petty parents, their plan is to take me to the cleaners in this divorce. Having been able to see this coming, I had diverted my money away from our joint account more than a year ago and have been spending on her (she’s been staying at home mother since before she became a mother) and our family from my business accounts ( I have a small business).
They pushed mediation for two months from today (they want to buy time to get to the 10 year anniversary and claim spousal maintenance + trying to prove that she applied for jobs and couldn’t find any…) and I’m trying to make it sooner so we can get over with it and I get to see what their claims have been (so far she’s holding her cards close to her flat chest).

My question to those who went through mediation and then court, do you suggest I reveal all my documentation during mediation knowing that 99% they will not accept anything less than the maximum they can get? Some of the documentations I have are about personal property that went into buying our house and about business valuation. Or shall I leave those out of the mediation and bring them up in court ?
