Contact your divorce attorney and if you did not have any divorce attorney, contact an attorney who handles divorces. If you want to try to do it on your own, provide the administrator of your ex's 401k plan with a copy of the divorce judgment which I assume awards you one-half of your ex's 401k and hopefully you will get the money. But you may need another court order to get it done so you would need to contact an attorney.
