my ex husband has signed a disclaimer for his inheritance to avoid this going into our family law matter. (Not that I would take this) but how can i prove that once settled he will then receive funds from his brother so he correct financial position is not show on family law matters. It will state that he has a property I have a property and I will have cash worth 40k which he will ask for half however after separation has been finalised will revive 100k. What do I do so I keep the 40 he will be better off and I have full time care of 1 child
