The Documents That Override Your Will

The Financial Sciences Company Published Oct 16, 2026

The short answer

A will governs only what passes through probate. Retirement accounts, life insurance, payable-on-death and transfer-on-death accounts, and property held with a right of survivorship pass by the form or the title, outside the will entirely. When the two disagree, the form wins: the Supreme Court has held that an employer plan must pay the person named on its documents, even a former spouse the decree divested, even decades after the form was signed. Forms go stale at four predictable moments — a marriage, a divorce, a death in the family, a rollover — and staying aligned means reading each form against the estate plan, not a one-time filing.

Many households finish an estate plan and assume the will now speaks for everything they own. It does not. For a large share of what an affluent family holds, a beneficiary form, an account agreement, or a line on a deed decides who receives the money. Those documents are short, often signed years ago, and in force until someone changes them.

What passes outside the will

A will controls property that goes through probate. Certain other instruments carry their own instructions, and the law honors them as written. The state’s estates code lists them: a provision in an insurance policy, a retirement account, a pension plan, a trust, a security, or an account with a financial institution that says money passes at death to a designated person is valid and is considered nontestamentary (the state’s estates code, §111.052). Nontestamentary means the will has no say.

In household terms, the list looks like this:

Retirement accounts — 401(k)s, 403(b)s, pensions, and IRAs pass to the beneficiary named on the plan or custodial form.
Life insurance — the policy pays the named beneficiary.
Payable-on-death and transfer-on-death registrations — bank and brokerage accounts, and, where state law allows it, a recorded transfer-on-death deed for real property.
Joint property with a right of survivorship — the surviving owner takes the whole, by title.

Under some states’ law, a joint account passes to the survivor only if a written agreement signed by the person who died says so; “JT TEN” on a statement is not enough (the state’s estates code, §113.151). The question is whether the forms and titles behind each account say what the will says.

The cases where the form beat the will

The Supreme Court has decided this question plainly. In 1974, a DuPont employee named his wife as beneficiary of his savings plan and named no contingent beneficiary. The couple divorced in 1994, and the decree divested her of any claim to his retirement plans. He never changed the form. When he died in 2001, the plan paid the balance, some $400,000, to the former wife, and a unanimous Court agreed the plan was right. In its words, the documents control (Kennedy v. Plan Administrator for DuPont, 555 U.S. 285 (2009)).

Eight years earlier, the Court reached the same result on different facts. A Boeing employee named his wife on his life insurance and pension plan, divorced in April 1994, and died two months later without changing either form. The state where he lived had a statute that cancels a former spouse’s designation after divorce, and his children relied on it. The Court held that the federal law governing employer plans overrides such a statute: the plan pays the beneficiary on its documents (Egelhoff v. Egelhoff, 532 U.S. 141 (2001)). Behind both decisions is one sentence of federal law: a plan fiduciary must act in accordance with the documents and instruments governing the plan (29 U.S.C. §1104(a)(1)(D)). In neither case did anyone argue the deceased intended the result. Intent was not the question. The form was.

The four moments a form goes stale

A beneficiary form is accurate the day it is signed; life then moves, and the form does not. The drift happens at four predictable moments.

A marriage. Accounts opened before the wedding still name a parent, a sibling, or no one. A second marriage adds the question of how children from the first are provided for, and the answer lives on the forms.
A divorce. The decree can say a former spouse gives up every claim, and the plan can still pay that spouse, as Kennedy shows. The form has to be changed at the plan, on the plan’s own paperwork.
A death in the family. When the named beneficiary dies first and no contingent was listed, the account has no instructions. What happens next depends on the plan document or account agreement.
A rollover. Money that moves from an employer plan to an IRA lands in a new account with its own agreement. Each IRA is a separate trust with its own written governing instrument (26 U.S.C. §408(a)), and the name on the old plan does not travel with the money.

How the forms and the estate plan get aligned

Alignment is a short list of disciplines.

An inventory, reviewed annually

One page that lists every account, policy, and registration, with the primary and contingent beneficiary on each and the date the form was last confirmed, read against the will and any trust. Reading it once a year, and after any of the four moments, is the whole method.

Contingent beneficiaries on every form

A primary beneficiary answers one question; a contingent answers the next, and the Kennedy form, with none named, shows what the silence costs. A transfer-on-death deed works the same way, in states that allow one: a beneficiary who does not survive the owner by 120 hours takes nothing, and that share lapses (the state’s estates code, §114.103).

Real estate, handled with the deed

In states that recognize transfer-on-death deeds, a will may not revoke or supersede one (the state’s estates code, §114.057(b)). A later will does not undo a deed recorded years ago; changing the outcome means recording a new instrument.

Naming a trust, carefully

Some families name a trust as beneficiary so that the trust’s terms, rather than one person, control what happens next, as in a blended family or where a beneficiary should not receive a lump sum. The trust must exist and be correctly identified on the form, its terms must fit the account it will receive, and the account’s own rules for trusts as beneficiaries have to be read before the form is signed. That is a decision for the attorney and the adviser to make together.

How we keep them aligned

We treat beneficiary forms as part of the plan, not paperwork beside it. When a household joins us, we build the inventory: every account, managed by us or not, every policy and registration, with the beneficiaries on each and the date confirmed. We read it against the will and any trust, and we send the attorney a list of every place the two disagree.

From there it is a rhythm rather than an event. The inventory is reviewed at least once a year and reopened whenever one of the four moments occurs. When a rollover comes through our office, the new form is completed with the transfer paperwork and compared to the estate plan before it is submitted. The point is not that nothing will ever be missed. The point is that someone is watching the whole picture, so the decision about who receives each account is made once, on purpose, and kept current.

What this does not mean

This article describes how the law treats the documents, not what any household should write on them. A will still matters; it governs everything that passes through probate and names who will handle the estate. Nothing here means a trust or a transfer-on-death registration suits every account. The state-law rules cited apply in one jurisdiction and differ elsewhere; the Supreme Court cases involved employer plans, and other accounts follow their own agreements and state law. The tax treatment of what a beneficiary receives is a separate subject. Who should inherit each account is a decision for the family and its attorney. Our role is to make sure the forms say what the family decided.

Frequently asked questions

Does a will override a beneficiary designation?

No. A beneficiary designation on a retirement account, life insurance policy, or payable-on-death account is nontestamentary, so the will does not govern it. The account pays the person on the form, and the Supreme Court has enforced that for employer plans even where the person named was a former spouse the decree had divested.

Does a divorce automatically remove a former spouse from my accounts?

Sometimes, and only partly. Some states treat a pre-divorce designation of a former spouse as ineffective for certain benefits. Federal law overrides those statutes for employer plans, so the plan pays the form. The reliable step is to change the form at each plan and custodian after the decree.

Do I need to name a new beneficiary after a rollover?

Yes. A rollover moves money into a new account with its own agreement and its own beneficiary form; the name on the old plan does not carry over. The new form should be completed with the rollover paperwork and checked against the estate plan before it is submitted.

Should I name my trust as beneficiary of my retirement account?

It depends on the family and the trust, and it is a decision for the attorney and the adviser together. A trust can control how and when money is distributed, but it must be correctly identified on the form and its terms must fit the account’s own rules for trusts as beneficiaries.
