A trust under agreement is a living trust created by a written contract between you and a separate trustee, who takes legal title to the assets you transfer in and manages them for the beneficiaries you name. The “under agreement” label simply tells you how the trust came into being: through a signed contract during your lifetime, rather than through a will that takes effect at death or through a declaration where you name yourself as trustee. Everything about how the trust runs, from investment powers to the timing of distributions, is spelled out in that one document.
How It Differs From Other Trusts
Three methods are commonly used to create a trust, and the names track the method:
- A trust under agreement is a contract between you and someone else who will serve as trustee. You sign, the trustee signs, and assets get transferred. Someone other than you holds and manages the property from day one.
- A declaration of trust is one where you declare yourself both settlor and trustee. There’s no second party. Many revocable living trusts are set up this way.
- A testamentary trust sits inside your will and doesn’t exist until you die. A probate court supervises its creation and appoints the trustee at that point.
All three are valid, and all can accomplish similar goals. The practical difference with a trust under agreement is that a separate trustee is already in place, which makes it a natural fit when you want professional management from a bank’s trust department or a financial institution, or when you want some distance from day-to-day control. Because it takes effect while you’re alive, it’s a type of inter vivos (living) trust.
The Three Roles
Every trust under agreement involves three roles, though one person can sometimes fill more than one of them.
The settlor (also called grantor or trustor) is the person who creates the trust, decides its terms, and transfers assets into it. You set the rules: who gets what, when they get it, and under what conditions.
The trustee holds legal title to the trust assets and manages them according to your instructions. In a trust under agreement, this is someone other than you. The trustee carries a fiduciary duty of loyalty, meaning they must administer the trust solely in the interests of the beneficiaries.1Legal Information Institute. Fiduciary Duties of Trustees
The beneficiary is the person or group who receives the benefits—income, property, or both. Beneficiaries can be individuals, charities, or other organizations. One firm rule: the sole trustee and sole beneficiary cannot be the same person, because the point of a trust is to separate legal ownership from the right to benefit.
Most trust agreements also name one or more successor trustees. If the original trustee dies, resigns, or becomes unable to serve, the successor steps in without court involvement.2Legal Information Institute. Trust Instrument
What Goes Into the Agreement
For a trust agreement to be legally valid, it needs several core elements: a clear intent to create the trust, identification of specific property being placed into it, designation of the settlor, trustee, and beneficiaries, and a lawful purpose.2Legal Information Institute. Trust Instrument A well-drafted document also covers four practical areas.
Distribution Instructions
This is the heart of the document. You specify how and when beneficiaries receive assets. Some trusts call for immediate distribution after a triggering event. Others stagger distributions over time, releasing funds when a beneficiary reaches a certain age or hits a milestone like graduating from college. You can also give the trustee discretion to make distributions based on a standard like the beneficiary’s health, education, or support needs.
Powers and Limitations
The agreement defines what the trustee can and cannot do: buy and sell investments, pay expenses, hire accountants and other professionals, make decisions about property. Some agreements grant broad discretion; others are very specific. More detail here means less room for disputes later.
Amendment and Revocation
If the trust is revocable, the agreement should explain exactly how you can change or cancel it. Under the Uniform Trust Code adopted in most states, a trust is presumed revocable unless the document expressly says otherwise. Revocation or amendment typically requires substantial compliance with whatever method the trust document specifies, usually a written amendment signed by you and, in many states, witnessed and notarized. If no method is specified, you can revoke or amend through any method that shows clear evidence of your intent.
Termination
The document should state when and how the trust ends. Common triggers include all assets being distributed, a beneficiary reaching a specified age, or a fixed date. When the trust terminates, the trustee distributes any remaining assets as directed and winds the arrangement down.
Revocable or Irrevocable
The single most consequential decision when you create a trust under agreement is whether it will be revocable or irrevocable. That choice drives your level of control, your tax treatment, and whether the trust shields assets from creditors.
Revocable Trusts
A revocable trust lets you change the terms, swap out beneficiaries, or dissolve the trust entirely at any time during your lifetime. You keep control. For tax purposes, the IRS treats a revocable trust as a grantor trust: its income, deductions, and credits flow onto your personal tax return, not a separate trust return.3Office of the Law Revision Counsel. 26 U.S. Code 671 – Trust Income, Deductions, and Credits Attributable to Grantors and Others as Substantial Owners A revocable trust can use your Social Security number rather than obtaining a separate tax identification number.4Internal Revenue Service. Instructions for Form 1041 and Schedules A, B, G, J, and K-1
The trade-off: because you retain so much control, creditors can reach the assets as though you owned them outright. A revocable trust offers no meaningful creditor protection during your lifetime, and those assets remain part of your taxable estate when you die.
Irrevocable Trusts
An irrevocable trust locks things down. Once you transfer assets in, you generally cannot take them back, change the beneficiaries, or alter the terms without the consent of all beneficiaries or a court order. You give up control in exchange for two things.
First, assets in an irrevocable trust are usually no longer part of your taxable estate, which can save your heirs substantial estate tax if your wealth exceeds the federal exemption. Under the One Big Beautiful Bill Act, the federal estate and gift tax exemption rises to $15 million per person starting January 1, 2026, with amounts above that threshold taxed at 40%. Second, because you no longer own or control the assets, your personal creditors generally cannot reach them.
The tax side gets more complicated. The trust becomes a separate taxpayer that must obtain its own Employer Identification Number and file its own annual Form 1041. Trust income tax brackets are severely compressed compared to individual rates: for 2026, a trust hits the top 37% federal rate on income above just $16,000, whereas an individual doesn’t reach that bracket until well over $600,000. That makes it important to distribute income to beneficiaries whenever the trust terms allow, so it’s taxed at the beneficiary’s typically lower rate instead.
Creating and Funding the Trust
Setting up a trust under agreement is a two-stage process, and the second stage is where people most often drop the ball.
Drafting and Execution
The first step is drafting the agreement with an attorney. The document translates your goals into specific legal provisions covering distributions, trustee powers, successor trustees, and the other components above. Attorney fees for a standard revocable trust vary widely, from roughly $1,000 to $10,000 depending on complexity and location.
Once drafted, the agreement needs formal execution. You and the trustee both sign. Most states require witnessing or notarization or both to ensure validity, though specific requirements vary by jurisdiction.2Legal Information Institute. Trust Instrument
Funding the Trust
A signed trust agreement that holds no assets accomplishes nothing. Funding means transferring ownership of assets from your name into the trust’s name. No trust arises over an asset until the transfer is actually completed; a promise to transfer property tomorrow doesn’t create a trust today.2Legal Information Institute. Trust Instrument The process depends on the type of asset:
- For bank and investment accounts, contact the financial institution to retitle the account in the trust’s name, typically formatted as “[Trustee Name], Trustee of [Trust Name], dated [date].”
- For real estate, execute a new deed transferring the property from your name to the trust. The deed has to be recorded with the local recorder’s office, and recording fees vary by jurisdiction.
- For life insurance, contact the insurer to change ownership of the policy to the trust and update the beneficiary designation. Transferring a policy into an irrevocable life insurance trust can count as a taxable gift.
- For retirement accounts, you usually can’t retitle them into a trust during your lifetime without triggering a taxable distribution. Instead, you name the trust as the beneficiary.
What Happens If You Don’t Fund It
This is where most estate plans fall apart. If you sign a beautifully drafted trust agreement but never retitle your assets, those assets sit outside the trust. They don’t get probate avoidance, creditor protection, or any other trust feature. They pass through your will, or through intestacy laws if you don’t have a will, and wind up in probate court, which is exactly what most people set up a trust to avoid.
A pour-over will can partially address this. It directs that any assets you own at death that aren’t already in the trust should be transferred into it. But those assets still have to go through probate first, so you lose the speed and privacy the trust was supposed to provide. The pour-over will is a safety net, not a substitute for properly funding the trust during your lifetime.
Taxes and Reporting
Tax treatment follows the revocable/irrevocable split, and getting this wrong leads to penalties and missed opportunities.
A revocable trust is invisible to the IRS during your lifetime. Because you retain the power to revoke, you’re treated as the owner. All income, deductions, and credits flow through to your personal Form 1040.3Office of the Law Revision Counsel. 26 U.S. Code 671 – Trust Income, Deductions, and Credits Attributable to Grantors and Others as Substantial Owners No separate tax ID, no separate return. After you die, the trust typically becomes irrevocable by its terms. At that point the trustee needs to get an EIN and start filing Form 1041 annually if the trust has taxable income or gross income of $600 or more.4Internal Revenue Service. Instructions for Form 1041 and Schedules A, B, G, J, and K-1
An irrevocable trust is a separate taxpayer from day one. It needs its own EIN and files Form 1041 each year. The trust pays tax on income it retains, and beneficiaries pay tax on income distributed to them, reported on Schedule K-1. The compressed brackets described above are the reason trustees often distribute income rather than accumulating it inside the trust.
On the estate and gift side, assets in a revocable trust remain part of your taxable estate. For 2026 the federal estate tax exemption is $15 million per individual ($30 million for married couples), with amounts above that threshold taxed at 40%. If your estate is below that threshold, federal estate tax isn’t a concern regardless of whether you use a trust. Transferring assets into an irrevocable trust during your lifetime can be a taxable gift. The annual gift tax exclusion for 2026 is $19,000 per recipient, so you can contribute up to that amount per beneficiary each year without touching your lifetime exemption.5Internal Revenue Service.

Creditor Protection and Its Limits
People sometimes assume that any trust automatically shields assets from creditors. It doesn’t, and the type of trust matters.
Because you can revoke a revocable trust and take the assets back at any time, courts treat those assets as effectively yours. Your creditors can reach into a revocable trust to satisfy your debts during your lifetime, and after your death creditors can still make claims against trust assets before they’re distributed. If creditor protection is the goal, a revocable trust won’t get you there.
An irrevocable trust provides real creditor protection because you’ve genuinely given up ownership. Your personal creditors can’t reach assets you no longer own or control. For added protection of beneficiaries, most well-drafted irrevocable trusts include a spendthrift clause, which prevents beneficiaries from pledging their trust interest as collateral and prevents their creditors from seizing trust assets before distribution.
Spendthrift protection has limits. Once assets are actually distributed to a beneficiary, the protection ends and creditors can pursue those funds. Courts in most states also carve out exceptions for child support obligations, so a spendthrift clause won’t block a court order to satisfy a child support judgment. And spendthrift provisions only protect beneficiaries, not the settlor. A self-settled trust, where you are both the settlor and a beneficiary, receives no spendthrift protection in most states.
Why People Use This Structure
The most common reason is probate avoidance. Assets held inside a properly funded trust pass directly to beneficiaries without going through probate court, saving time, money, and hassle. Probate can take months or even years depending on the complexity of the estate and the court’s backlog.
Privacy is another draw. A will becomes a public record once it’s filed with the probate court; anyone can look up who inherited what and how much. A trust agreement stays private. Only the trustee and beneficiaries need to know its terms.
A trust under agreement also fits situations where you want professional management from the start. Naming a corporate trustee or a trusted financial professional provides oversight that a simple will can’t match, particularly when beneficiaries are minors, have disabilities, or lack the experience to manage a large inheritance. A structured distribution schedule keeps a 19-year-old from burning through an entire inheritance in a year.
Control over timing rounds out the list. You can specify that a beneficiary receives a third of the trust at age 25, another third at 30, and the remainder at 35. You can tie distributions to life events or give the trustee discretion to withhold funds if a beneficiary is struggling with addiction or other challenges. That level of granularity simply isn’t available through a will.
