There was no major inciting event or action (e.g. affair) that put us on the path towards possible divorce. Rather it is the result of my wife's unstable and childish behavior. I am completely naive to the process (although I have begun to do research on the matter and will look for a lawyer) but she has a legal-savvy family with attorneys.
Background for questions:
When we married, she supposedly had no money to her name. She demonstrated that her income supported her entire budget although I now very much suspect that she may have given all her money to her sister/family prior to marriage. Trustingly, I put a lot of my own money (several years of savings) into a joint account to which we both put in our incomes for nearly three years. Now she says she wants to manage her money/income separately, with minimal contribution to the joint account.
Thankfully, no children yet.
Q1) I can do the same but is there a way I can recover some of the money I put into the joint account?
Q2) How well can she siphon her current income from her private account to lawyer happy family, etc. by cash withdrawals and other methods on which she will no doubt be advised? Will I be able to get access to a paper trail that reveals this during divorce (if it finally gets to that point)?
