- Beneficiary designations on retirement accounts, life insurance and bank accounts are legally binding contracts that override your will, and an outdated form can send your assets to the wrong person.
- Only 24% of Americans have a will, and even those who have a will often neglect to align their beneficiary designations with the rest of their estate plan.
- Simple errors can lead to probate, unnecessary taxes, and family disputes.
You spent thousands on an estate plan. You signed the will. You funded the trust. And none of it matters because that beneficiary form you filled out when you started a new job 15 years ago may overshadow everything.
Beneficiary designations on retirement accounts, life insurance policies and bank accounts payable upon death are legally binding contracts. They operate completely outside your will and trust. When these forms are out of date, incomplete, or misaligned with the rest of your plan, the result could be assets going to an ex-spouse, a child accidentally disinherited, or a six-figure tax bill that no one saw coming.
according to Caring.com’s 2025 Estate Planning SurveyOnly 24% of American adults have a will – down from 33% in 2022. But even among the minority who make plans, beneficiary designation errors remain one of the most common and costly mistakes. Here are five mistakes you should avoid.
1. Failing to Update Your Beneficiaries
This is the most frequent (and often the most damaging) mistake beneficiaries make. You get married, divorce, have a child, or lose a spouse, and the beneficiary forms on your 401(k), IRA, and life insurance policies stay exactly the same.
The legal consequences are real. In the 2001 Supreme Court case Egelhoff vs EgelhoffThe court ruled that a former spouse was entitled to the decedent’s life insurance proceeds because the beneficiary form was never updated after the divorce, even though state law would have voided the designation. Federal law (ERISA) governs employer plans and win forms.
The solution is straightforward: Review each beneficiary designation after any marriage, divorce, birth, death, or major financial change. Keep a master list of all accounts with beneficiary designations and update it annually.
2. Assuming Your Will Will Outlast Beneficiary Designations
This misconception persists in families. A will only controls assets that pass through your estate, meaning assets that don’t already have a named beneficiary or surviving joint owner. Retirement accounts, life insurance policies, annuities, and bank accounts payable on death all bypass the will entirely.
So if your will says, “Everything goes equally to my three children,” but your $500,000 IRA still has your ex-spouse’s name on it, your ex gets the IRA. Your children don’t get anything from that account, and there is little legal recourse.
Americans have more than $9 trillion in employer-sponsored retirement plans and IRAs. For many families, these accounts represent the largest single asset in the estate. The beneficiary form is a significant financial risk to consider later.
3. Leaving out contingent beneficiaries
Many people name the primary beneficiary and leave the contingent (backup) line blank. This creates a serious problem: If your primary beneficiary dies before you do (or in a common accident at the same time), the account defaults on your estate. This means it goes through probate, which is the exact outcome most estate plans are designed to avoid.
Probate involves time, legal fees, and public disclosure. For retirement accounts, it can also accelerate tax consequences. When an IRA passes through an estate rather than passing directly to a named beneficiary, the distribution rules become less favorable, potentially forcing faster withdrawals and larger tax implications.
Always name at least one contingent beneficiary on each account. If your situation is complex (blended family, minor children, or dependents with special needs) consider naming a trust as a contingent beneficiary, but only with the guidance of an estate planning attorney.
4. Designating your estate as a beneficiary
Some account holders intentionally designate “my estate” as the beneficiary, thinking it makes things simpler. It does the opposite. Naming your estate as the beneficiary of a retirement account or life insurance policy forces the estate through probate and takes away many tax-advantaged options for your heirs.
When a retirement account goes directly to the nominee, the beneficiary can often stretch out distributions for up to 10 years. When it passes to the estate, the account may need to be distributed within five years or even faster, depending on whether the original owner initiated required minimum distributions. That compressed timeline could push heirs into higher tax brackets.
Life insurance proceeds are the same. Paid to a named beneficiary, they are generally income tax-free. Once the assets are paid out, they become part of the probate estate, subject to estate taxes and creditor claims.
5. Relying on joint accounts instead of proper designations
Some families try to bypass estate planning altogether by adding a child or family member as a joint owner on bank accounts, investment accounts or even real estate. The logic seems simple: when one owner dies, the other automatically inherits.
But joint ownership comes with serious risks that most families don’t consider. A joint account holder has full legal access to the funds during the lifetime of both owners. This means the account is exposed to the other owner’s creditors, lawsuits, divorce proceedings, and financial mismanagement. If your adult child incurs debt or is sued, jointly held funds may be seized.
Joint accounts can also create unexpected tax consequences and financial aid complications. As College Investor has detailed, parent-child joint accounts come with hidden financial risks that range from Medicaid eligibility problems to FAFSA reporting issues.
A better approach: Bank and investment accounts use the payable on death (POD) or transfer on death (TOD) designations. These keep the account in your name alone during your lifetime but automatically transfer it to your named beneficiary upon death – without probate and the risk of joint ownership.
What this means for your family’s finances
Beneficiary designation mistakes not only cause legal headaches – they directly impact your family’s financial security. An outdated form could send millions of dollars away from the people you are supposed to protect. A missing contingent beneficiary can trigger probate costs that affect your heirs’ inheritance. A joint account set up for convenience can expose your savings to someone else’s creditors.
The financial stakes are especially high for families who have retirement accounts as their primary assets. With the average 401(k) balance for Americans aged 55-64 exceeding $200,000, a single beneficiary error could redirect a meaningful portion of a family’s wealth.
