You may not be able to avoid taxes on it. The issue is that you are now receiving those monies to which you are entitled and you are receiving them now. Talk to your tax professional or divorce attorney about whether a trust account opened in your name as initial trustee with your children as beneficiaries or others as beneficiaries and future trustees would be most beneficial to you or placing it into another tax deferred type of account wherein you don't have access to it for a while would be the better option for you.
