Beneficiary Designations: Why They Override Your Will

What Are Beneficiary Designations?

A beneficiary designation is a contractual instruction you give to a financial institution, retirement plan, or insurance company specifying who will receive the asset or account when you die. These designations are separate from your will and operate independently of your estate plan's other documents. The institution is legally obligated to distribute the asset to the named beneficiary. No court involvement required, no probate, no waiting. To understand the full picture of who receives what and how under different scenarios, read our inheritance guide.

The term "beneficiary designation" covers several related mechanisms. A "payable-on-death" (POD) designation on a bank account instructs the bank to pay the account balance directly to the named person at death. A "transfer-on-death" (TOD) designation on a brokerage account similarly transfers securities to the named beneficiary. Retirement accounts have their own beneficiary designation forms administered by the plan custodian. Life insurance policies have beneficiary designations managed by the insurer.

The IRS provides detailed guidance on retirement plan beneficiary designations, including the rules that govern how different types of beneficiaries, spouses, non-spouse individuals, trusts, and estates, must handle required minimum distributions from inherited retirement accounts.

Why Beneficiary Designations Override Your Will

Here is why: a beneficiary designation is a binding contract between you and the financial institution. When you open a retirement account or purchase a life insurance policy, you enter into a contract that includes the beneficiary designation provisions. The institution has a contractual obligation to distribute the asset to the named beneficiary, and your will cannot override that contract.

Courts across the country have consistently upheld this principle. In case after case, estranged family members, ex-spouses, and people the deceased clearly did not intend to benefit have received assets because the beneficiary designation was never updated. The law does not look into the account holder's intent. It only looks at what the designation form says at the time of death.

This is why financial advisors, estate attorneys, and the CFPB's consumer protection guidance all stress that beneficiary designations must be reviewed and coordinated with your overall estate plan. They are not a one-time task you complete when you first open an account. An outdated beneficiary designation can undo years of careful planning.

Accounts That Use Beneficiary Designations

Primary vs. Contingent Beneficiaries

Every beneficiary designation should include both primary and contingent beneficiaries.

Primary beneficiaries are the first in line to receive the asset. You can name multiple primary beneficiaries and specify the percentage each receives. For example: "50% to Jane Smith (spouse), 25% to John Smith (son), 25% to Mary Smith (daughter)."

Contingent beneficiaries (sometimes called secondary beneficiaries) receive the asset only if all primary beneficiaries have predeceased you or otherwise disclaim the inheritance. Without a contingent beneficiary, an account whose primary beneficiary has died must pass through your estate, going through probate and losing the direct transfer benefit.

As a best practice, name at least one contingent beneficiary for every account that has a beneficiary designation. For retirement accounts, naming your estate as contingent beneficiary is generally a poor choice because it eliminates the option for individual beneficiaries to use the 10-year rule. Instead, name individuals or a properly structured trust.

Per Stirpes vs. Per Capita Designations

When naming beneficiaries with potential descendants, you typically choose between two distribution methods: per stirpes and per capita. Let's break it down.

Per stirpes (Latin for "by the branch") means that if a named beneficiary predeceases you, that beneficiary's share passes to their descendants. For example, if you name your three children equally per stirpes, and one child dies before you leaving two grandchildren, those grandchildren together receive the deceased child's one-third share (one-sixth each). The shares pass "down the branch" of each child's family line.

Per capita (Latin for "by the head") means the surviving named beneficiaries divide the asset equally, with nothing automatically passing to descendants of a deceased beneficiary. Using the same example with per capita, if one of three children predeceases you, the remaining two children each receive one-half. The deceased child's family line receives nothing unless they were separately named.

Most estate planning attorneys recommend per stirpes designations because they more often match what account holders actually intend and prevent accidental disinheritance of grandchildren. The right choice depends on your family structure and intentions.

Common Beneficiary Designation Mistakes

The following mistakes are surprisingly common and can have serious, irreversible consequences:

• Naming the estate as beneficiary. This routes the asset through probate, potentially adding months of delay, subjecting it to estate creditors, and eliminating favorable IRS tax treatment for retirement accounts. Except in specific planning scenarios, naming your estate as beneficiary is almost always the wrong choice.
• Failing to name a contingent beneficiary. Without a backup, an account whose primary beneficiary has died reverts to the estate or the plan's default provisions. Always name at least one contingent.
• Not updating after divorce. Most states have laws that automatically revoke beneficiary designations to a former spouse on certain accounts upon divorce. Federal law (ERISA) overrides state law for most employer retirement plans, meaning a divorce does not automatically remove an ex-spouse from a 401(k) beneficiary designation. After any divorce, update all beneficiary designations immediately.
• Not updating after marriage or children. Many people open retirement accounts before starting a family and never update the beneficiary forms. A new spouse or child who is not named as beneficiary receives nothing from the account.
• Naming a minor child directly. Minor children cannot legally receive significant assets directly. If a minor is named and inherits, a court must appoint a guardian or custodian to manage the funds until the child reaches adulthood, an expensive and cumbersome process. Instead, use a custodianship under the Uniform Transfers to Minors Act, or name a trust as the beneficiary for the child's share.
• Naming a person with special needs directly. A direct inheritance may disqualify a special needs beneficiary from means-tested government benefits like Medicaid or SSI. Instead, name a properly structured special needs trust as the beneficiary.

How to Update Your Beneficiary Designations

Updating beneficiary designations is straightforward once you know what to do. Here is what to do next:

1. Inventory all accounts. List every IRA, 401(k), 403(b), life insurance policy, bank account, and brokerage account you own. Include employer-sponsored benefits, individual accounts, and any group life insurance through work.
2. Obtain the current designation for each account. Contact each institution and request a copy of your current beneficiary designation on file. You may find outdated designations you forgot about.
3. Complete updated forms. Each institution has its own beneficiary designation form. For employer plans, obtain the form from your HR department or plan administrator. For IRAs and brokerage accounts, most institutions allow online updates through your account portal. For life insurance, contact your agent or the insurer directly.
4. Submit and confirm. After submitting, follow up to confirm the institution has recorded the new designation. Request written confirmation and save it with your estate planning documents.
5. Review with your estate planning attorney. Make sure your beneficiary designations are coordinated with your will, trust, and overall estate plan. Your attorney should review them during any estate plan update.

Life insurance policies use insurer-specific beneficiary forms, so always request the current form directly from the carrier and keep written confirmation after the update is processed.

Special Situations: Trusts, Minor Children, and Special Needs

In some situations, naming an individual directly as beneficiary is not the right approach, and a trust should be considered instead.

Minor children. Rather than naming a minor child directly, consider using a custodianship under the Uniform Transfers to Minors Act (UTMA), which is simple to set up and manages funds until the child reaches 18 to 25 depending on the state, or a fully funded trust that specifies when and how distributions are made and at what age the child receives the principal. A trust gives you more control over how and when the child accesses the funds.

Special needs beneficiaries. If you have a child or other beneficiary who receives Medicaid, Supplemental Security Income (SSI), or other means-tested government benefits, a direct inheritance above a small threshold will likely disqualify them from those programs. A special needs trust (also called a supplemental needs trust) holds the inheritance for the beneficiary's benefit without cutting off their government assistance. Name the special needs trust, not the individual, as beneficiary of your accounts.

Naming a trust as retirement account beneficiary. This is the most complex scenario and requires careful planning. Unless the trust meets specific IRS requirements for "look-through" or "see-through" treatment, naming a trust as the beneficiary of an IRA or 401(k) can result in the entire account being distributed within 5 years and taxed immediately at the trust's compressed income tax rates. An estate planning attorney with experience in retirement account planning should design any trust intended to receive retirement account benefits.
