Beneficiary designations are one of the most overlooked — and most consequential — financial decisions you make. They determine who receives the money in your retirement accounts, life insurance policies, and certain bank accounts when you die. Most importantly: they override everything in your will. A will that leaves everything to your current spouse means nothing if your 401(k) still names your ex-spouse as beneficiary.

Which Accounts Have Beneficiary Designations

  • 401(k), 403(b), 457(b) plans
  • Traditional and Roth IRAs
  • Life insurance policies
  • Annuities
  • Bank accounts with Payable-on-Death (POD) designation
  • Brokerage accounts with Transfer-on-Death (TOD) designation
  • Health Savings Accounts (HSAs)

These accounts collectively often represent the majority of a person's wealth. And they transfer entirely outside the probate process — faster, more cheaply, and completely bypassing your will.

Primary vs. Contingent Beneficiaries

Primary beneficiary: Receives the account if they are alive when you die. You can name multiple primary beneficiaries and specify percentages (e.g., 50% each to two children).

Contingent beneficiary: Receives the account if all primary beneficiaries have predeceased you. Without a contingent beneficiary, the account falls back into your estate and goes through probate — the slow, expensive process you were trying to avoid.

Always name both. Always name a contingent beneficiary for every account.

The Most Common Mistakes

Naming your estate as beneficiary. Naming "my estate" forces the account through probate, delays distribution, and can generate unnecessary taxes. Name individuals or a trust.

Naming a minor child directly. Minor children cannot legally receive large inheritances directly. If no trust is established, a court will appoint a conservator to manage the money — slow, expensive, and not your choice. If you have minor children, establish a trust and name the trust as the beneficiary, or your estate plan should include a custodian designation under UTMA.

Outdated designations after divorce. Many states automatically revoke beneficiary designations to an ex-spouse upon divorce — but not all, and not for all account types. Federal law governs employer retirement plans, and divorce does not automatically change a 401(k) beneficiary. Review every designation immediately after a divorce.

Never updating after major life events. Marriage, divorce, birth of a child, death of a named beneficiary — each requires a designation review. Reviewing your beneficiaries every 2–3 years takes 30 minutes and prevents years of legal problems.

Per Stirpes vs. Per Capita

If you name multiple beneficiaries, understand the two distribution options: per stirpes means a deceased beneficiary's share passes to their children (your grandchildren). Per capita means a deceased beneficiary's share is split among surviving beneficiaries. For most families with children, per stirpes is the more intuitive choice — it keeps assets in the family line.
