OK, let's start the year out right and invest some time in making sure that the beneficiaries that are listed for your assets make sense in light of your current circumstances. I'm talking about any financial asset that has a "designated beneficiary", such as life insurance, qualified retirement accounts (IRA's, 401K's, etc.) annuities and any bank account that has been established as a "POD" (payable on death) account.
If you remember nothing else from this post remember this: Your will or living trust does not control the distribution of the assets listed above. If an asset has a designated beneficiary, then upon your death the remaining funds are going to that beneficiary (or beneficiaries) and no one else. The company in charge of the account doesn't give a hoot about what your will or living trust says.
One perfect example of when this can cause an enormous problem is when there is a divorce. If you don't update your beneficiary designation after the divorce then your ex could end up with the proceeds upon your death. Wow.
Please look at that list in the first paragraph again and note that we're not talking about small change here. If you're like most of the population then your retirement accounts are probably the largest assets you have with the possible exception of your house. Also, the pay-out of your life insurance may represent the largest percentage of your estate. So it's worth it to sit down with your estate planning attorney and make sure that you get your beneficiaries right.
