A decanted trust is a new irrevocable trust that holds assets poured over from an older irrevocable trust whose terms no longer work. The trustee drafts a replacement instrument with updated provisions, transfers the assets into it, and leaves the original trust behind, much like decanting wine from one vessel to another. More than 40 states now authorize some form of trust decanting, making it one of the most accessible ways to update an irrevocable trust without a court proceeding.
Why Trustees Decant
The simplest reason is to fix a drafting problem. A typo in a distribution formula, an ambiguous beneficiary reference, or a missing definition can all be corrected by moving the assets into a clean replacement trust, usually without a judge’s approval.
Changed circumstances drive decanting just as often. A trust written in 2005 may carry investment restrictions or distribution standards that no longer fit. If a beneficiary develops a disability, the trustee may need to restructure distributions so the beneficiary can still qualify for Supplemental Security Income or Medicaid. Pouring the assets into a properly designed special needs trust accomplishes that without the delay of litigation.
Tax planning is another driver. Decanting can move a trust’s legal home to a state with better income tax treatment, update provisions to take advantage of newer planning techniques, or restructure trusts that were designed around a different federal estate tax exemption than today’s.
Administrative cleanup rounds out the list: changing trustee succession rules, simplifying investment procedures, extending the trust’s duration where state law permits, or consolidating several small trusts into one.
Where the Authority to Decant Comes From
Decanting is a trustee’s power, not a beneficiary’s, and it does not exist by default. The authority has to come from one of two places: the trust document itself or state law. Some well-drafted trusts include an express decanting clause. When the document is silent, the trustee looks to the statute of the state governing the trust.
Over 40 states and the District of Columbia have enacted decanting statutes. About half follow the Uniform Trust Decanting Act, a model law drafted by the Uniform Law Commission; the rest have their own versions with varying rules.1Uniform Law Commission. Uniform Trust Decanting Act The differences matter. Some give trustees broad flexibility, others impose tight guardrails on what can change. In the handful of states with no decanting statute, a trustee who wants to modify an irrevocable trust generally has to petition a court or use a nonjudicial settlement agreement instead.
How Much a Trustee Can Change Depends on Discretion
The single most important variable in a decanting is how much discretion the original trust gives the trustee over distributions. Most statutes draw a line between two categories, and the line decides what the new trust can look like.
Expanded Discretion
A trustee has expanded discretion when the trust grants broad, unconstrained authority to distribute principal, with language along the lines of “the trustee may distribute principal as the trustee determines appropriate.” This provides the widest latitude when decanting. The trustee can alter distribution standards, change the timing of payouts, add spendthrift protections, and modify administrative provisions. Under the Uniform Trust Decanting Act, a trustee with expanded discretion can also create or modify a power of appointment for a current beneficiary, potentially letting that person direct where their share goes after death.
Limited Discretion
A trustee has limited discretion when distributions are tied to a specific standard, such as “health, education, maintenance, and support.” Those ascertainable standards restrict the trustee’s power, and the restriction carries into decanting. Under the UTDA, a trustee with limited discretion can only decant into a new trust that gives each beneficiary “substantially similar” beneficial interests.1Uniform Law Commission. Uniform Trust Decanting Act In practice, the trustee can update administrative and investment provisions but cannot fundamentally reshape who gets what or when.
Many older trusts use ascertainable standards. A trustee who assumes they can make sweeping changes without checking the original trust language may inadvertently exceed their authority, which can expose them to personal liability or invalidate the decanting.
What Decanting Cannot Do
Even with expanded discretion, certain modifications are off-limits in nearly every jurisdiction:
- Adding people as current beneficiaries who were not already current beneficiaries of the original trust.
- Bringing in new remainder beneficiaries who were not already somewhere in the original trust’s beneficiary structure.
- Eliminating a vested interest. If a beneficiary has an unconditional right to income or a fixed annuity payment, the trustee cannot decant that right away. Many states explicitly protect fixed income interests from reduction.
- Removing a currently exercisable withdrawal right. Most statutes require the new trust to preserve an identical right or leave enough assets in the original trust to satisfy it.
- Violating fiduciary duties. A trustee who is also a beneficiary faces additional restrictions and in many states cannot exercise the decanting power if it could benefit them personally.
Within those limits, the kinds of changes most often made through decanting include tightening or loosening distribution standards, adding spendthrift protections against a beneficiary’s creditors or divorcing spouse, granting a beneficiary a power of appointment, changing successor trustee provisions, relocating the trust to a different state, and extending the trust’s duration or consolidating multiple trusts.
How the Decanting Process Works
The mechanics vary by state, but the sequence is predictable. Getting any step wrong can invalidate the transfer, so trustees who attempt this without experienced counsel are taking a real risk.
It starts with a careful read of both the original trust document and the applicable state statute. The trustee needs to confirm they have the legal authority to decant, identify whether they hold expanded or limited discretion, and understand exactly which modifications the law permits. Most of the legal work happens here.
Next, the trustee works with an attorney to draft the new trust instrument. The document has to satisfy both the state’s decanting statute and the trustee’s fiduciary obligations. The trustee should also document the reasons for decanting; a clear record of the decision-making process provides protection if a beneficiary later challenges the action.
Most decanting statutes then require written notice to beneficiaries before the transfer takes effect. The Uniform Trust Decanting Act includes specific notice provisions, and many states impose a waiting period between the notice and the effective date. The notice typically includes copies of both the original and new trust instruments so beneficiaries can evaluate the changes and raise objections or seek court intervention if they believe the decanting exceeds the trustee’s authority.
Once the waiting period expires without objection, the trustee formally transfers the assets into the new trust. In some cases, the original trust continues to exist as an empty shell; in others, it terminates by its own terms once the assets are removed.
Tax Effects of a Decanted Trust
Tax is where decanting gets genuinely complicated. The IRS announced in 2011 that it would not issue rulings on the income tax, gift tax, or generation-skipping transfer tax consequences of decantings that result in a change of beneficial interests. As of Revenue Procedure 2024-3, that position has not changed. Trustees and their advisors are left piecing together guidance from private letter rulings and general tax principles.
Income Tax
The central question is whether moving assets from one trust to another is a realization event, as if the trust had sold the assets. Under the standard set by the Supreme Court in Cottage Savings Association v. Commissioner, no realization occurs as long as the beneficial interests in the new trust are not “materially different” from those in the original. Administrative changes like updating trustee provisions or changing the trust’s situs generally pass that test. A decanting that significantly restructures who receives what, or when, leaves real ambiguity about whether the IRS would treat it as taxable.
Gift Tax
Gift tax issues usually land on beneficiaries, not on the trustee. A trustee acting in a fiduciary capacity with no beneficial interest in the trust does not make a gift by decanting. But a beneficiary who consents to or acquiesces in a decanting that reduces their interest could be treated as having made a taxable gift, particularly in states where the beneficiary has a legal right to object. If the trustee is also a beneficiary with broad discretion over distributions to themselves, they may be treated as holding a general power of appointment, and reducing that power through decanting could trigger gift tax.
Generation-Skipping Transfer Tax
Trusts that are exempt from the GST tax, either because they were irrevocable before September 25, 1985, or because the grantor allocated GST exemption to the trust, need extra care. A safe harbor in the Treasury Regulations preserves GST-exempt status as long as no beneficial interest shifts to a beneficiary in a lower generation than the prior holder and the trust’s vesting period is not extended. Moving the trust to a state with a longer perpetuities period can inadvertently blow that safe harbor if the new jurisdiction extends the vesting period beyond what the original trust allowed.
Any decanting that touches beneficial interests should involve a tax advisor who specifically understands these issues. The cost of professional guidance is small compared to an unexpected tax bill that could consume a meaningful portion of the trust.
When Decanting Is Not the Right Tool
Decanting is not the only way to modify an irrevocable trust, and it is not always the best option. Two alternatives are worth knowing about.
A nonjudicial settlement agreement is a contract among the interested parties, typically the trustee, the grantor if living, and all current and future beneficiaries. Because everyone signs off, the result is hard to challenge later. But if even one beneficiary objects, or a minor beneficiary lacks a representative free of conflict, the process stalls. An NJSA also cannot violate a material purpose of the trust. These agreements work well for changes everyone supports, such as updating trustee compensation or resolving an ambiguity, and poorly when the change would reduce any beneficiary’s interest.
Judicial modification is available when decanting authority does not exist and the parties cannot agree. If the grantor and all beneficiaries consent, most state courts will approve the modification even if it conflicts with a material purpose of the trust. If the grantor is deceased or some beneficiaries do not consent, the court can still approve the change as long as it is not inconsistent with a material purpose of the trust and the interests of nonconsenting beneficiaries are adequately protected.2Nebraska Legislature. Nebraska Code 30-3837 – Modification or Termination of Noncharitable Irrevocable Trust Court proceedings cost more and take longer than decanting, but they produce a binding order that provides certainty. For high-value trusts or contentious family dynamics, that oversight may be worth the price.
Decanting works best when the problems with the existing trust are clear, the trustee has adequate discretion, and the changes fall within what the applicable statute allows. It is riskier when proposed changes significantly alter beneficial interests, when the trustee has limited discretion, or when the trust holds assets with substantial unrealized gains. Trustees who push the limits of their decanting authority without professional guidance risk personal liability, unexpected tax consequences, and litigation from beneficiaries who feel shortchanged.
