Why on earth would you still have a joint account?
Have your own accounts and tell him nothing about your life! If you pay things out of the joint account til D, then just deposit money into it from your account in order to pay bills. You need a very clear paper trail about what is being paid and by whom. If you have ever read my story, you can be assured I am speaking truth. And you will see all the advice here be -- hide your money, take your half, do whatever you can. The MLCer will take everything, and whatever he can't take, he will use against you in court to try to get more than his share or alimony, etc.
This is coming from a woman of faith who started standing in 2014. Finances and faith are two different things. Protect the former, nurture the latter.
I believe I will see the bounty of the Lord in the land of the living. Wait for the Lord with courage. Be stouthearted, and wait for the Lord.
