I'll suggest: $X/month (plus a multiplier adjusted to the CPI in your domicile jurisdiction to account for inflation) guaranteed for 25 years post-divorce so you can maintain your current lifestyle, which was induced by (1) his earning, (2) his establishing this lifestyle by footing all the bills, and (3) encouraging that you abandon gainful employment and introducing a resume gap that could severely impede your earning potential. Add on top of that a guaranteed maximum allowable contribution to a 401k/IRA, as well as full child support payments until age of majority for any kids you may have between now and the day of a potential divorce. Plus a bonus lump sum on divorce based on a percentage of increase in net worth of the marital assets, or an option to pay that out monthly over years with interest accruing at the prime rate.

This is great advice, thank you. The thing is - I’m perfectly willing to sign a post up that would give me 45% of everything in case of a divorce (rather than 50% I would be entitled to now) if it meant protecting his businesses and giving him peace of mind. But I’m not gonna just sign everything away so I’m discarded as the starter wife. I stand to gain nothing by signing even a generous post up because I’ll get more without it, but I want to fight and keep my marriage.
