Beneficiary Designation Mistakes That Bypass Your Tennessee Will

Your will does not control your largest assets. Retirement accounts, life insurance policies, payable-on-death bank accounts, and transfer-on-death brokerage accounts all pass directly to the named beneficiary — regardless of what your will says. If your will leaves everything to your children but your 401(k) still names your ex-spouse, your ex-spouse gets the 401(k).

This is not a theoretical problem. It is one of the most common and expensive estate planning failures in Tennessee.

How Beneficiary Designations Override Your Will

Under Tennessee law and federal ERISA rules, a beneficiary designation on a financial account is a contract between you and the financial institution. It operates entirely outside of probate and entirely outside of your will.

When you die, the institution pays the named beneficiary directly. The probate court has no authority over these assets. Your executor has no claim to them. Your will's instructions are irrelevant to any account with a valid beneficiary designation.

This applies to:

• 401(k) and 403(b) retirement plans
• Traditional and Roth IRAs
• Pension plans
• Life insurance policies
• Payable-on-death (POD) bank accounts
• Transfer-on-death (TOD) brokerage accounts
• Health savings accounts (HSAs)

The Five Most Common Mistakes

1. Naming an Ex-Spouse and Never Updating

Tennessee law under T.C.A. Section 31-1-102 automatically revokes a will provision benefiting a former spouse upon divorce. But this statute does not apply to beneficiary designations on retirement accounts governed by federal ERISA law.

If your employer-sponsored 401(k) names your ex-spouse as beneficiary and you never file a change-of-beneficiary form with the plan administrator, your ex-spouse inherits the full account at your death. Your current spouse or children receive nothing from that account, no matter what your will says.

The U.S. Supreme Court confirmed this in Egelhoff v. Egelhoff — ERISA preempts state law, and the beneficiary designation controls.

2. Naming No Beneficiary at All

If you skip the beneficiary designation entirely — or if all named beneficiaries predecease you — the account defaults to the institution's standard policy. Most default to "the estate," which means the account goes through probate.

For retirement accounts, this creates two problems: the assets are subject to probate creditor claims, and the distribution options for inherited IRAs become far less favorable when the beneficiary is an estate rather than a named individual.

3. Naming Minors Directly

Tennessee law prevents minors from controlling assets exceeding $50,000 without court-supervised guardianship. If you name a 10-year-old as the direct beneficiary of your $200,000 life insurance policy, the insurance company cannot pay the child directly. The court must appoint a conservator to manage the funds until the child turns 18 — at which point the child receives the full amount with no restrictions.

The fix: name a trust as the beneficiary, with instructions on how and when distributions should be made.

4. Naming Only a Primary Beneficiary

If your primary beneficiary dies before you and you have not named a contingent (backup) beneficiary, the account defaults to the estate. Always name at least one contingent beneficiary on every account.

5. Using Per Stirpes vs. Per Capita Without Understanding the Difference

If you name "my children, per stirpes" and one child predeceases you, that child's share passes to their children (your grandchildren). If you name "my children, per capita," the deceased child's share is divided among the surviving children only — the grandchildren receive nothing.

Many beneficiary forms do not clearly explain this distinction. Choosing the wrong option can disinherit an entire branch of your family.

The Tennessee-Specific Wrinkle

Tennessee does not recognize transfer-on-death deeds for real property. This means you cannot add a beneficiary designation to your home deed like you can in most other states. Your home must pass through probate, joint ownership, or a trust.

However, Tennessee does allow TOD designations for vehicles under T.C.A. Section 55-3-118. You can designate a beneficiary on your vehicle title so it transfers outside of probate.

This inconsistency means you need to think about beneficiary designations and property titling as two separate systems. Your financial accounts have one transfer mechanism (beneficiary designations), and your real estate has another (deed titling or trust).

How to Audit Your Beneficiary Designations

A beneficiary audit takes one afternoon and prevents years of legal disputes:

1. List every account that allows a beneficiary designation: retirement plans, life insurance, bank accounts, brokerage accounts, HSAs
2. Contact each institution and request a copy of the current beneficiary designation on file
3. Check for accuracy: Is the named beneficiary still who you want? Is there a contingent beneficiary? Are any named beneficiaries deceased?
4. File updates for any account where the designation is outdated, missing, or incorrect
5. Keep copies of all updated beneficiary forms with your estate planning documents

Do this every time you experience a major life event: marriage, divorce, birth of a child, death of a beneficiary, or a significant change in your financial situation.

Coordinating Designations with Your Will

Your will and your beneficiary designations should work together, not against each other. Your will controls probate assets. Your beneficiary designations control non-probate assets. If they tell different stories, the beneficiary designation wins every time.

The Tennessee Basic Estate Planning Kit includes a beneficiary designation tracker that walks you through auditing every account and coordinating the designations with your overall estate plan.
