From the voice of someone who walked a very expensive and painful financial lesson with my ex husband - please consider speaking with your attorney before giving out any financial records ~ or at least removing your social security number and personal infomation (DOB) from them so that your ex can't borrow $$ in your name!
You may especially want to talk to your attorney if he files bankruptcy - as this may affect you if his debts were incurred during your marriage. Please know I'm not giving financial or legal advice - just know what happened to me and it wasn't PRETTY!!
As far as dealing with the issues between him and your son ~ that is always tough.
Prayers and good thoughts sent your way!
PINK HUGS,
