Beneficiary Designations vs. Your Will: Why the Two Must Work Together

Published September 2nd, 2026 by KHJ Law Team

You can have a carefully drafted will and still have your wishes overridden by a single outdated form you filled out years ago. Beneficiary designations quietly control a large share of what most families pass on, and keeping them aligned with your will is essential.

Many people are surprised to learn that their will does not control all of their assets at the time of their death. Some of the most valuable things a person owns, including retirement accounts, life insurance, and certain bank and investment accounts, pass directly to the joint owner or to whoever is named on a beneficiary designation form, completely outside the will. When the two disagree, the designation usually wins.

At Klafehn, Heise & Johnson P.L.L.C., we help families across Monroe, Orleans, and Genesee Counties make sure these systems work together rather than against each other. Here is what you need to understand.

Two Ways Property Passes at Death

Broadly speaking, assets pass to the next generation through one of two channels, and most estates contain a mix of both.

Through the Will (Probate Assets)

Property owned in your name alone, such as a home titled solely to you, a personal bank account, or your possessions, generally passes under the terms of your will, through the probate process. This is the part of your estate the will actually governs.

Outside the Will (Non-Probate Assets)

Other assets pass by operation of a designation or form, no matter what the will says. These include retirement accounts such as IRAs and 401(k)s, life insurance proceeds, accounts with a “payable on death” or “transfer on death” designation, and jointly owned property with rights of survivorship. The beneficiary form, not the will, decides where these go, and for many families these are the largest assets of all.

Why the Conflict Happens

The trouble arises because these designations are often set up once, when an account is opened or a job is started, and then forgotten for decades. Life moves on through marriages, divorces, births, deaths, and changes of heart. But the form stays frozen at the moment it was signed.

The result is some of the most painful outcomes we see. An ex named on a life insurance policy twenty years ago receives the payout instead of the current family. A retirement account names only one of several children because it was set up before the others were born. A new will carefully divides the estate, while the largest assets sail past it to people the decedent did not intend to benefit.

The Events That Should Trigger a Review

Beneficiary designations should be reviewed and, if needed, updated after any significant life event, including:

  • Marriage or divorce, whether for you or for a named beneficiary;
  • The birth or adoption of a child or grandchild;
  • The death of someone you had named;
  • A major change in your relationship with a named beneficiary; and
  • Any update to your will or broader estate plan.

That last point matters most. A will update is incomplete if the beneficiary forms are not reviewed at the same time. The two have to be considered together, or the plan you just paid to update may not work the way you think.

Special Situations That Need Care

Some designations call for more thought than simply writing a name on a line.

Minor Children

Naming a minor child directly as a beneficiary can create complications, because a minor cannot legally control the funds. The money may end up under court-supervised guardianship rather than being managed as you would wish. A trust is often the better destination, and it lets you set the terms for how and when the funds are used.

Beneficiaries With Special Needs

Leaving assets directly to a person who relies on needs-based government benefits can unintentionally disqualify them. A properly drafted supplemental needs trust, named as the beneficiary, can preserve both the inheritance and the benefits.

Retirement Accounts

The tax rules governing inherited retirement accounts are complex and have changed in recent years. Who you name, and whether a trust is involved, can significantly affect the taxes your heirs ultimately pay. This is an area where coordinated advice is especially valuable, because a well-intended choice can carry an avoidable tax cost.

A Simple Habit That Prevents Big Problems

Reviewing your designations does not have to be a major undertaking. Keeping a list of which accounts and policies carry beneficiary designations, and glancing at that list whenever your life changes or you revisit your estate plan, is often enough to catch a problem before it becomes permanent. The review takes little time, and the mistakes it can prevent can last a generation.

Coordinate, Don’t Just Fill Out Forms

The goal is a plan in which the will, any trusts, and every beneficiary designation point in the same direction. That coordination is the whole point of an estate plan, and it is exactly what gets lost when designations are treated as routine paperwork rather than part of the plan itself.
