According to Allentown, Pa. investment adviser Kevin Brosious, accounts with beneficiary designations - such as IRAs, 401 (k)s, insurance policies and annuities - aren't governed by your will. "So even if you wrote an ex out of your will eons ago, he or she would still get, say, your IRA if you never changed its beneficiary," Allenton added. As a result, he advised to reviews choices periodically, especially after major life events. And don't leave beneficiary forms blank.
Your accounts then go to probate court for distribution, and rules on who gets what which vary by state.
