<prompt> Human: My drug addict ex-wife secretly cashed out two 401ks from jobs she held previously during the last 6 months of our marriage. She never told me about this or the money. I only discovered that this happened when the IRS sent me a notice addressed to both of us for collection of back taxes from this undeclared income about 40,000 from tax year 2012. The total amount owed is about 3,000. Im angry about this and I want to know what recourse I may have to make this her problem solely.  <response>: Talk to your divorce lawyer.
