What Assets Should Not Be in a Will?

Most people assume a will covers everything they own. In practice, it covers far less than that—and knowing the difference can have a significant impact on what actually happens to your estate.

When you ask what assets should not be in a will, the answer comes down to one principle: if an asset already has a legal mechanism for transferring ownership at death—through a beneficiary designation, a title structure, or a trust—your will generally has no authority over it. Those assets pass outside of probate, regardless of what your will says.

Here is what that means in practical terms.

Executive Summary

A will is a foundational estate planning document, but it does not govern everything you own. Certain assets—including retirement accounts, life insurance policies, and jointly held property—transfer outside of probate through beneficiary designations or ownership structures. Including these assets in a will can create confusion, contradictions, and unintended outcomes for your loved ones. Understanding what assets should not be in a will is a critical step toward a coordinated, effective estate plan.

What Does a Will Actually Control?

A will controls probate assets: property that is in your name, with no designated beneficiary and no automatic transfer mechanism. At death, those assets go through the probate process, where a court oversees their distribution according to your will (or state intestacy law if you have no will).

Everything else—assets that transfer by contract, by title, or by operation of law—passes entirely outside of your will. These are non-probate assets, and they represent a large portion of most people’s estates.

Which Assets Should Not Be Included in a Will?

Retirement Accounts Such as 401(k)s, IRAs, and 403(b)s

Retirement accounts are governed by beneficiary designation forms, not your will. When you open a 401(k) or IRA, you name a primary beneficiary—and ideally a contingent beneficiary—directly with the plan administrator. At death, those funds transfer to the named beneficiary, bypassing probate entirely.

The will is simply not part of the equation—unless no beneficiary is named.

What Happens When a 401(k) Has No Beneficiary Designation?

This is where things can become genuinely difficult. If a retirement account has no named beneficiary—or if the named beneficiary has already passed away—the funds may default to the account holder’s estate. At that point, the account flows through the will (or state intestacy law if there is no will), and probate becomes the distribution mechanism.

For married individuals, this situation, while not ideal, is often more manageable. A surviving spouse typically has more options under ERISA and tax law, including the ability to roll the inherited account into their own IRA.

For unmarried individuals, the situation can become significantly more complex. Non-spouse beneficiaries who inherit through an estate rather than a direct designation face more restrictive distribution requirements and a potentially longer, more burdensome probate process.

At Oak Road Wealth Management, we have seen this firsthand. Families navigating the loss of a loved one who are simultaneously dealing with a retirement account stuck in probate—facing unclear timelines, additional costs, and tax consequences that could have been avoided entirely with a current beneficiary designation. It is a difficult situation made harder at an already painful time.

The lesson is straightforward: keep your retirement account beneficiary designations current, and make sure you have both a primary and contingent beneficiary named.

Life Insurance Policies

Life insurance proceeds transfer directly to the named beneficiary on the policy—not through your will. If your will includes a reference to life insurance proceeds, that language does not redirect the funds. The policy contract controls.

If no beneficiary is named on the policy, the proceeds may flow into your estate, where they become subject to probate and potentially to creditor claims—defeating one of the primary advantages of life insurance as an asset transfer tool.

Jointly Held Property with Right of Survivorship

Property held in joint tenancy with right of survivorship—a home, a joint bank account, or a jointly held investment account—passes automatically to the surviving owner at death. Your will has no authority over it.

Similarly, tenancy by the entirety (available in some states for married couples) and community property with right of survivorship operate on the same principle: the surviving co-owner inherits automatically by operation of law.

Accounts with Transfer on Death (TOD) or Payable on Death (POD) Designations

Bank accounts and brokerage accounts can carry Payable on Death (POD) or Transfer on Death (TOD) designations. These designations allow the account to pass directly to a named individual without going through probate.

As with retirement accounts and life insurance, the beneficiary designation controls—not the will. A conflicting instruction in a will does not override a TOD or POD designation.

Assets Held in a Revocable Living Trust

If you have transferred assets into a revocable living trust, those assets are owned by the trust—not by you individually. At death, the trustee distributes those assets according to the trust document, not your will.

Wills and trusts work alongside each other in an estate plan, but they govern different assets. A pour-over will can direct remaining assets into a trust at death, but assets already in the trust are not controlled by the will.

Why Does It Matter If These Assets Are Mentioned in a Will?

Including non-probate assets in a will does not typically invalidate the will itself, but it creates real risks:

• Contradictions: If a will says one thing and a beneficiary form says another, the beneficiary form wins—which may not match your actual wishes.
• Confusion for survivors: Family members may believe the will controls an asset it legally cannot, leading to conflict and delayed administration.
• False confidence: You may believe your estate plan is fully coordinated when it actually has significant gaps.

Why Reviewing Both Your Will and Beneficiary Designations Is Essential

A will alone is not an estate plan. A complete, coordinated plan requires reviewing both your will and all beneficiary designations together—to make sure they are consistent, current, and working toward the same outcome.

What Should Be Reviewed?

• Retirement account beneficiary designations (primary and contingent)
• Life insurance beneficiary forms
• TOD/POD designations on bank and brokerage accounts
• How property is titled (joint tenancy, tenancy in common, individual ownership)
• Assets held in trust and trust documents

Life events that should prompt a review include marriage, divorce, the death or incapacitation of a named beneficiary, the birth of a child or grandchild, a significant change in assets, or simply the passage of several years. A beneficiary designation made twenty years ago may no longer reflect your family situation or your intentions.

And as we have seen with 401(k) accounts and unmarried individuals—outdated or missing designations do not just create administrative headaches. They can create real financial and emotional hardship for the people you were trying to protect.

What Should Actually Be in a Will?

For context, a will is generally the appropriate place for:

• Solely owned real estate and personal property with no other transfer mechanism
• Personal belongings such as jewelry, artwork, and vehicles
• Instructions for naming a guardian for minor children
• Distribution of residuary assets—anything not otherwise covered by a designation or title structure
• Naming an executor to oversee the probate process

Frequently Asked Questions

What assets cannot be passed through a will?

Assets that transfer through beneficiary designations, joint ownership, or trust ownership are not controlled by a will. This includes retirement accounts (401(k)s, IRAs, 403(b)s), life insurance policies, jointly held property with right of survivorship, and bank or brokerage accounts with TOD or POD designations.

Does a will override a 401(k) beneficiary designation?

No. The beneficiary designation on a 401(k) controls over a will. If the two conflict, the designation wins. The exception is when no beneficiary is named—in that case, the account may default to the estate and pass through the will or state intestacy law, which can create complications, particularly for unmarried individuals.

What happens if a 401(k) has no named beneficiary?

If a 401(k) has no named beneficiary, it may default to the account holder’s estate and pass through probate. For unmarried individuals, this can be especially burdensome—non-spouse beneficiaries face more restrictive distribution rules and a more complex process than a surviving spouse would. This is a situation that can often be avoided entirely by keeping designations current.

Should life insurance be included in a will?

Generally, no. Life insurance proceeds pass directly to the named beneficiary on the policy, regardless of what a will says. To change who receives life insurance proceeds, the beneficiary designation must be updated directly with the insurance company.

How often should beneficiary designations be reviewed?

There is no universal rule, but reviewing designations after any major life event—marriage, divorce, death of a beneficiary, birth of a child—is a sound practice. Many financial professionals suggest a general review every three to five years even without a triggering event.

Can a will and a beneficiary designation contradict each other?

Yes, and it happens more than most people expect. When there is a conflict, the beneficiary designation typically controls for accounts and policies governed by it. This is one reason why reviewing both your will and all beneficiary designations together—as part of a unified plan—matters.
