Will vs. trust, and where the pour-over will fits

A will controls the probate estate after probate. A trust controls what is titled to it. The pour-over will joins the two. What each document does, by asset.

Suppose a client who has decided to do estate planning asks whether they need a trust, or whether a will is enough. Then the client reads that a trust-based plan includes a will anyway, and asks why there are two.

An advisor cannot answer that for a client, but can explain what each document controls, which depends on how each asset is held. A will controls property that is in the decedent’s own name at death with no beneficiary named, and only after a court admits the will to probate. A revocable trust controls property that has been made trust property, during the settlor’s life and after death. The pour-over will connects them: it is the will in a trust-based plan, and at death it sends the probate estate (the property left in the decedent’s own name) into the trust, after probate. Which of these a particular household ends up signing is for the household to decide, with an attorney for anything specific to its own situation.

What a will controls

A will has no effect during its maker’s life, and at death it needs a court before it does anything. Under the Uniform Probate Code, section 3-101, a decedent’s real and personal property devolves at death to the persons the will names, subject to the homestead and family allowances, exempt property, the surviving spouse’s elective share, the rights of creditors, and administration. The will proves that transfer only once it is admitted: under section 3-102, a will must be declared valid by an order of informal probate or an adjudication of probate “to be effective to prove the transfer of any property or to nominate an executor,” with an exception for the small-estate affidavit procedure. The Code is a model act; each state enacts its own version, and the thresholds and procedures vary.

The will reaches the probate estate: property that was in the decedent’s own name at death and that no other instrument sends somewhere else. Nothing has to be retitled for the will to reach it. Section 6-101 makes “a provision for a nonprobate transfer on death” in an insurance policy, an account agreement, a pension or individual retirement plan, a trust, a deed of gift or other conveyance, or a similar written instrument “nontestamentary.” The beneficiary form on an IRA, the transfer-on-death registration on a brokerage account, and the terms of a trust that already holds an asset all pass the asset outside probate, so the will does not reach it unless the account’s own terms let a will name the beneficiary, or the estate ends up as the beneficiary. Property held jointly with a right of survivorship passes to the surviving owner by the form of its title. Those forms can fall out of step with the will and trust; beneficiary designation drift covers how that happens.

A will is also the instrument that names an executor (called a personal representative in many states), and it is the usual place a parent nominates a guardian. The Code’s definition of a will, in section 1-201, includes an instrument that does nothing more than appoint an executor, nominate a guardian, revoke another will, or limit who takes by intestacy. Section 5-202 lets a parent appoint a guardian for a minor child “by will or other signed writing.” Once a parent has made that appointment, it takes effect on the parent’s death, on an adjudication that the parent is incapacitated, or on an examining physician’s written finding that the parent can no longer care for the child, whichever comes first and subject to the objection rights in section 5-203. The guardian becomes eligible to act by filing an acceptance within 30 days, and then petitions the court to confirm the appointment unless it was confirmed earlier. The appointment “does not supersede the parental rights of either parent.” A trust instrument does not name the person who represents the estate in court, and it is not where a parent ordinarily nominates a guardian.

A will can also create a trust. The Uniform Trust Code, section 401, lists creation by will, or by another disposition that takes effect at the settlor’s death, as one of the ways a trust comes into being. A trust created this way is called a testamentary trust. Unlike a revocable living trust, it receives its property only through probate: the will passes the property through probate, and the trustee then holds it until the age the will sets. It is common where a beneficiary may be a minor.

What a revocable trust controls

A trust is created, under section 401, by transferring property to a trustee during the settlor’s lifetime, or by the owner declaring that they hold specific property as trustee. As the official comment puts it, “a trust is not created until it receives property.” The property interest need not be substantial, and the instrument is not invalid because property arrived long after signing. The trust document states the terms, and an asset comes under them when it becomes trust property, usually by retitling the account or the deed to the trustee; for a trust the owner declares over property they already hold, the comment says a schedule listing the assets can be enough. An asset that was never made trust property in one of these ways stays outside the trust, regardless of its terms.

While the trust is revocable, the settlor keeps control. Section 602 lets the settlor revoke or amend the trust unless its terms expressly make it irrevocable, the default for trusts created after a state’s enactment. Under section 603, while the trust is revocable and the settlor has capacity, the “rights of the beneficiaries are subject to the control of, and the duties of the trustee are owed exclusively to, the settlor.” Section 601 sets the capacity to create, amend, or revoke a revocable trust at the same level as the capacity to make a will. A settlor can serve as trustee of their own revocable trust; section 402 requires only that the same person not be both sole trustee and sole beneficiary. So the settlor, as trustee, can keep managing the trust’s accounts and property as before.

A trust, unlike a will, operates during the settlor’s life. Its terms can name a successor trustee and set out how the settlor’s incapacity is determined, so that if the settlor can no longer manage the assets the trust holds, the person named in the trust manages them under the trust’s terms without a court appointment. The trust also continues after death. Its provisions for transfer at death are nontestamentary under section 6-101 of the probate code, so what the trust holds is distributed or kept in trust under its own terms, and the trustee can keep holding and managing property for a beneficiary over years. The successor trustee guide describes that role from the trustee’s side.

Because a trust reaches only what it holds, it needs upkeep a will does not: each account and deed acquired later has to be made trust property too. A trust that was signed and never funded holds no property at all, and most revocable trusts are never fully funded.

Where the pour-over will fits

A trust-based plan still has a will, and the will’s main gift goes to the trustee. The probate code’s version of the Uniform Testamentary Additions to Trusts Act, section 2-511, says a will “may validly devise property to the trustee of a trust established or to be established” during the testator’s lifetime, or at the testator’s death by the devise itself where the will identifies the trust and its terms are set out in a written instrument other than the will. The devise is valid “regardless of the existence, size, or character of the corpus of the trust,” and it “is not invalid because the trust is amendable or revocable, or because the trust was amended after the execution of the will or the testator’s death.” Unless the will provides otherwise, property given this way becomes part of the trust and is administered under the trust’s terms, including amendments made after the testator’s death, and if the trust is revoked or terminated while the testator is alive, the gift fails.

In this arrangement the distribution terms are in the trust. The will still names the executor and ordinarily carries the parent’s nomination of a guardian, but it leaves the rest of the probate estate to the trustee. The trust’s terms then govern both what the trust already held and what the will adds, and there is no second set of distribution terms to keep consistent.

Everything that passes under the pour-over will passes through probate first, because it is still a will and the property it reaches was still in the decedent’s own name. How much that is depends on how much was titled to the trust during life. Simple will vs pour-over will covers the two kinds of will in more detail, and what happens when a trust is unfunded at death follows the probate route to the end.

A three-asset example

Take a hypothetical household that signs a revocable trust and a pour-over will on the same day, then retitles one account and leaves the rest alone. At death, what happens to each asset depends on how it was held. A document controls an asset only where the title or the beneficiary form sends the asset to it.

The asset inventory worksheet is one way for a household to list each asset with how it is held, which is what the household and its attorney need in front of them to see where each asset would go. Naming a trust as IRA beneficiary has tax consequences of its own and is a question for counsel.

What an advisor can explain

An advisor who coordinates estate planning can explain all of this in general terms: what a will, a trust, and a pour-over will each control. An advisor can also hand over a list of what to gather, so the household can see for itself how each account and deed is held, and can run the meeting schedule and follow up on whatever is still open.

Which documents a particular household should sign, and whether a particular asset belongs in a trust, are questions about that household’s own situation. Those are for the household to decide, with an attorney when the household wants advice on its own facts. The platform’s own will-or-trust guide puts it this way: “Questions about which fits your situation are for an attorney.” Keeping to what the documents do, and leaving their application to the household and its counsel, keeps an advisor on the education side of the line between education and legal advice.

How Bancroft handles it

The will questionnaire asks how the rest of the estate should be distributed, with two answers: directly to named beneficiaries, or poured over into the household’s revocable trust. The help text beside the question describes what each answer does. If the household chooses pour-over, the next screen lists the trusts the household has already finalized on the platform. Picking one copies the trust’s name, date, trustee, and successor trustees into the will, so the two documents identify the same instrument. A household whose trust was made elsewhere, or is being made in the same session, enters those details itself.

The will-or-trust guide asks six questions: children under 18, property in more than one state, probate, privacy, managing assets over time, and keeping documents current. The result lists the topics the household marked and, for each one, how a will and a trust handle it. It gives no recommendation. It notes that a trust-based plan also includes a pour-over will, and it ends with two equal actions, start a will or start a trust, for the household to choose between.

Funding is a separate step after signing, and it is where the trust’s control over each asset is established. When an asset in the household’s inventory is marked for the trust, the platform drafts a funding letter for it from the inventory record. Approved letters go to the household as one packet; the household marks each letter mailed and can upload the institution’s confirmation to the Digital Safe, and the advisor’s view shows which approved letters have not gone out. What banks actually want in a funding letter covers the letters themselves, and the trust funding guide covers the steps.

Generating a will or a trust carries no per-document fee on any plan, and a trust is updated by restatement, also at no charge. A household that wants a licensed attorney to look at a particular document can request attorney review where it is offered, at $299 per document, paid to the attorney.

This article is general information about wills, revocable trusts, and pour-over wills under the model Uniform Probate Code and Uniform Trust Code. It is not legal advice and does not create an attorney-client relationship. Each state enacts its own version of these rules, and the terms of a particular will or trust control, so questions about a specific household’s documents or situation should be put to counsel licensed where the household lives.

Frequently asked questions

Does a trust-based estate plan still include a will?

Ordinarily it includes a pour-over will, whose residuary clause gives the probate estate to the trustee of the revocable trust, which the Uniform Probate Code’s section 2-511 validates regardless of how much the trust holds. The will also names an executor and is the usual place a parent nominates a guardian for a minor child; a trust instrument ordinarily does neither.

Does a revocable trust avoid probate?

For the property titled to it. A trust’s provisions for transfer at death are nontestamentary under section 6-101 of the model probate code, so what the trust holds passes under its own terms without probate. Property left in the settlor’s own name with no beneficiary designation is still part of the probate estate, and reaches the trust only through the pour-over will after administration.

Can a will create a trust?

The Uniform Trust Code’s section 401 lists creation by will as one of the ways a trust comes into being, and a trust created that way is a testamentary trust. The property passes under the will, through probate, and the trustee then holds it under the terms the will sets, which is one way a will provides for a beneficiary who may be a minor.

What controls an IRA or a life insurance policy, the will or the trust?

Neither, as long as the beneficiary form names someone who survives. Section 6-101 of the model probate code treats a nonprobate transfer-on-death provision in an insurance policy or a retirement plan as nontestamentary, so the asset passes under that provision rather than under the will. If the form names the trust, the trust’s terms take over from there; if it names no one, or no one named survives, the account’s own terms often send it to the estate, and then the will controls. Naming a trust on a retirement account has tax consequences of its own and is a question for counsel.

Who decides whether a household uses a will or a trust?

The household, with an attorney for advice on its own situation. An advisor can explain in general terms what each document controls and can coordinate the meetings and the follow-up. The platform’s will-or-trust guide lists the topics a household marks and how a will and a trust each handle them, without a recommendation, and leaves the household with two equal choices.
