Name beneficiaries. After years of thinking I'd named a beneficiary on my 401(k), I recently checked my online account to find it blank. Take a few minutes to ensure all your retirement or investment accounts have the right beneficiary listed (note that you'll need your beneficiary's Social Security number to make it official). This isn't fun to think about, but it's a small task that, if ignored, can cause more than a headache for your heirs. Revisit auto-save (or set it up!). Automatic savings is a smart strategy because it doesn't require any ongoing effort. But don't forget to revisit the amount you're saving, especially if your income has gone up or your goals have changed.
