Naming and Changing Beneficiaries
One of the biggest areas that gets forgotten in estate planning is your IRA.
On plans like your IRA, or 401 (k) a will has no jurisdiction. In other words if your ex-spouse is named as a beneficiary on your retirement plan account the day you die, they get your plan monies. Even if you wrote your ex out of your will it does not apply to an IRA.
The key is to review your choices periodically, especially after a life altering event. Also, do not leave IRA beneficiary forms blank, If it is blank it will go to probate court for distribution and rules on who gets what vary state by state.
Keep yourself straight and stay up to date.
