How do beneficiary designations affect what’s in my will?

Beneficiary designations are powerful estate-planning tools that determine who receives specific nonprobate assets at death. In plain terms: when an asset has a valid beneficiary designation, that designation generally controls who gets the asset — even if your will says something different. This interaction can streamline transfers, but it also creates risks if designations are out-of-date, inconsistent with your overall plan, or don’t reflect your current wishes.

Below I explain the mechanics, common pitfalls, legal limits, and practical steps to align beneficiary designations and wills so your estate transfers as you intend.

Why beneficiary designations usually override a will

Many financial accounts and contracts are governed by their own beneficiary forms or plan documents. Those instruments (for example, an IRA beneficiary form or a life insurance claim form) create a contractual right for the named beneficiary to receive proceeds at the owner’s death. Because those accounts pass outside probate, the executor of your will cannot change the recipient for those assets (unless the beneficiary designation itself is invalid or the account’s rules allow modification).

Authoritative sources: The IRS and Department of Labor explain that retirement plan distributions and many insurance proceeds are paid according to plan or policy terms rather than estate documents (see IRS and DOL guidance at irs.gov and dol.gov). The Consumer Financial Protection Bureau also explains how payable-on-death and transfer-on-death designations bypass probate (consumerfinance.gov).

Common assets that use beneficiary designations

  • Retirement accounts: 401(k), 403(b), traditional and Roth IRAs (plan rules and the IRS/ERISA framework apply). Note: spousal protections may require spousal consent for non-spouse beneficiaries in many qualified plans (DOL guidance).
  • Life insurance policies: Proceeds generally pay directly to the named beneficiary.
  • Payable-on-death (POD) and transfer-on-death (TOD) designations: Bank accounts, brokerage accounts, and some securities registrations.
  • Annuities: Death benefits typically follow the annuity contract’s beneficiary form.
  • Some employer plans and pension benefits: Governed by plan documents and federal ERISA rules.

Because these assets commonly bypass probate, they will often not be distributed by your will or by a probate court order unless the designation is invalid, or the asset reverts to the estate due to no surviving beneficiary.

Legal limits and special rules

  • Spousal rights: Many employer retirement plans and IRAs have federal or state protections. For example, some plans require a spouse’s written consent before you name a non-spouse beneficiary. Check plan documents and state law. (See DOL at dol.gov.)
  • The SECURE Act (2019) changed retirement-account distribution rules: most non-spouse beneficiaries who inherit after 2019 must distribute inherited retirement plan balances within 10 years (with limited exceptions), which affects tax planning and long-term income strategies (IRS guidance).
  • Minors as beneficiaries: Naming a minor directly can create problems because institutions typically cannot transfer funds to a minor without a custodian, court-appointed guardian, or a trust. Consider naming a trust or using a custodial account.
  • Invalid or ambiguous designations: If a designation is not valid (e.g., the beneficiary predeceased you and no contingent beneficiary is named), the asset may revert to your estate and then be distributed under your will and state probate law.

Real-world consequences (examples from my practice)

In my 15 years of advising clients, I’ve seen the same patterns: a well-intended will that says one thing and beneficiary forms that say another. A common example: a client believed his life insurance proceeds would support his surviving spouse per his will. However, he’d named his children as primary beneficiaries on the insurance form years earlier. The insurer paid the children directly, and the widow had to pursue a separate claim — a stressful, avoidable conflict.

Another frequent case involves retirement accounts. The 2019 SECURE Act’s 10-year rule surprised many families used to spousal rollover strategies. In one situation, a decedent’s IRA named a sibling who then faced an accelerated taxable distribution timeline that the decedent’s estate plan had not anticipated.

How to coordinate beneficiary designations and your will

  1. Inventory accounts and beneficiary forms: List every asset with a beneficiary form (retirement plans, IRAs, life insurance, annuities, POD/TOD accounts, and employer plans).
  2. Match each account to your estate plan: Confirm that each beneficiary designation supports your current wishes and your will’s instructions. If you want assets funneled to a trust (for example, to control distributions to minors), name the trust as the beneficiary on the account — not just in your will. A “pour-over” will that leaves assets to a trust won’t capture nonprobate assets unless they are titled to the estate.
  3. Use contingent beneficiaries: Name secondary beneficiaries to avoid assets reverting to the estate if a primary beneficiary predeceases you.
  4. Consider hiring an estate attorney when naming a trust as beneficiary: Trust language must be precise, and account custodians may require exact trust details (trust name, date, trustee’s name).
  5. Communicate changes and keep documents consistent: Tell your executor and key family members where to find beneficiary forms and how you expect accounts to be handled.

Specific planning options to align outcomes

  • Name a trust as beneficiary: This allows you to control timing and conditions of distributions (useful for minor beneficiaries or spendthrift protection). Confirm the custodian accepts trust designations and provide a copy of the trust.
  • Joint ownership vs. beneficiary designation: Joint tenancy with rights of survivorship transfers to the co-owner automatically; it’s not governed by your will. Consider the tax and creditor implications before adding joint owners.
  • Pour-over will + revocable living trust: A pour-over will can move probate assets into a trust, but it won’t affect assets with separate beneficiary designations unless those accounts are retitled or the beneficiary forms updated.

Common mistakes and how to avoid them

  • Forgetting to update after life events: Divorce, remarriage, births, adoptions, and deaths should trigger an immediate review. I recommend reviewing beneficiary forms annually or after each life event.
  • Assuming the will controls everything: It doesn’t for nonprobate assets. Change beneficiary forms at the account custodian — not in your will.
  • Naming a minor without a plan: Instead, name a trust or guardian to manage funds.

What to do today (practical checklist)

  • Gather all beneficiary designation forms and account statements.
  • Verify primary and contingent beneficiaries for each account.
  • Update any designations that contradict your will or current wishes.
  • If you want controlled distributions, name a trust as beneficiary and confirm the custodian accepts the trust.
  • Consult an estate attorney if you have blended family issues, substantial retirement accounts, or complex tax considerations.

Contesting beneficiary designations

Contesting a beneficiary designation is typically harder than contesting a will because beneficiary forms are contractual. Successful challenges usually require proof of invalidity, lack of capacity, fraud, undue influence, or improper execution. Seek legal counsel early if you suspect a problematic designation (state law and courts vary).

Estate taxes and probate considerations

Beneficiary designations don’t eliminate estate taxes. For large estates subject to federal or state estate taxes, the asset’s value at death may still be included in the decedent’s gross estate for tax purposes (see IRS estate tax guidance at irs.gov). However, bypassing probate can reduce administrative delay and some probate costs.
