What Types of Trusts Can Be Modified?
Several types of trusts can be modified or amended with court approval, including:
- Special needs trusts
- Asset protection trusts
- Charitable trusts
- Irrevocable trusts
If the trust document restricts the ability to modify or amend a trust, or if the person authorized to make changes (the settlor) is unavailable or incapacitated, court involvement will be necessary to order the modification or amendment to the legal document. Courts may approve trust modifications if the grantor (settlor) and all beneficiaries agree to the changes.
What If the Settlor Is Deceased?
If the settlor is deceased or unable to provide consent, modifying a trust becomes more complex. Courts generally will not allow trust modifications that contradict the material purpose of the trust as established by the settlor. However, modifications may be approved if there are changed circumstances. Our Phoenix probate attorneys can help you explore your options if you are considering a trust modification. We are here to provide legal advice and answer any questions you may have about the modification process.
When to Modify or Terminate a Trust in Phoenix, Arizona
Generally, there are two types of trusts: a revocable trust and an irrevocable trust. A revocable trust allows the grantor to change, modify, or revoke the trust at any time. Such a trust can be modified or terminated without any court involvement.
On the other hand, an irrevocable trust is irrevocable and cannot be easily changed. However, the law recognizes that circumstances may change, making it necessary to modify or terminate a trust to accomplish the settlor’s goals.
There are several reasons why someone might seek to modify an irrevocable trust. For example, the beneficiaries and/or trustee may wish to change the successor trustee or the beneficiaries of the trust seek some tax advantage.
In some cases, the trustee may feel that the trust is no longer fulfilling its material purpose or that changes are required to ensure proper trust administration or there has been a material change in tax law. In such situations, an attorney can work with the beneficiaries, settlor, and trustee to determine whether a modification or termination of a trust in Phoenix, Arizona is achievable or appropriate.

The Legal Processes Required to Change or End a Trust
A revocable trust can be modified or terminated by the settlor. The grantor simply needs to follow the procedure outlined in the revocation clause. It’s an irrevocable trust which requires court involvement to modify.
There are narrow means by which an irrevocable trust may be modified. Arizona’s trust modification statute is ARS 14-10411. If all beneficiaries agree that a trust should be modified, they can petition the court to make these changes so long as it does not materially alter the purpose of the trust. Similarly, if all beneficiaries agree that the trust should be terminated, they may do so with court approval.
In situations where the beneficiaries cannot agree, courts may still decide to modify or terminate the trust if it can be demonstrated that such changes would be possible if all beneficiaries concurred. Additionally, the parties requesting the change must prove that the beneficiaries who disagree would not be negatively affected by the modification. A knowledgeable trust lawyer in Phoenix can provide more information about the legal processes required to change or terminate trusts under Arizona law.
Decanting – An Alternative to Modification
Decanting a trust offers a flexible alternative to traditional trust modification, allowing the transfer of trust property from one trust to another with more favorable terms. Unlike modifying a trust, which often requires significant legal documentation and court involvement, decanting can streamline the process by shifting assets into a new or existing trust. This approach is particularly useful for addressing changes in tax laws or ensuring proper estate tax planning.
However, it’s important to consult with an experienced legal team to ensure that decanting aligns with the trust’s material purpose and complies with all relevant tax laws. Before proceeding, a disclaimer about potential legal and tax implications should be discussed to preserve the integrity of the attorney-client relationship.

What About “Decanting” a Trust?
If you’re familiar with the term “decanting” in the context of wine, you already have a basic understanding of how it works. Just as wine is poured from one bottle into another, decanting a trust involves “pouring” the assets of an existing trust into a new trust or another pre-existing trust.
How Do I Know If a Trust Can Be Decanted in Arizona?
The legal authority to decant a trust can be specified in the terms of the trust by the settlor or authorized by Arizona state law (ARS 14-10819). Under ARS 14-10819, the trustee has the authority to decant a trust without requiring prior court approval, provided the original trust document does not explicitly prohibit decanting.
Even if decanting is permissible, several factors may ultimately prevent it, such as:
- The original trust agreement expressly prohibits decanting.
- A beneficiary’s right to distributions has already vested.
- The Trustee’s discretion to distribute assets is limited by the trust agreement.
- The new trust does not materially interfere with the old trust’s objectives.
If you are considering decanting a trust, a consultation with a Phoenix, Arizona estate planning attorney can help you understand your options and ensure the process aligns with the legal requirements and the material purpose of the trust.

FAQs
What is trust modification?
Trust modification is the legal process of altering specific terms, administrative rules, or distributions within an existing trust document. This allows a trust to adapt to changes in tax laws, family dynamics, or asset values without dissolving the trust entirely.
What is the difference between trust amendment and trust termination?
A trust amendment changes specific provisions of the trust, such as swapping a trustee or updating a beneficiary, while keeping the trust active. Trust termination completely dissolves the legal arrangement, resulting in the final distribution of all assets to the beneficiaries and closing the trust forever.
When can a trust be modified in Arizona?
A trust can be modified when its original purpose becomes unlawful, impossible to fulfill, or when unanticipated circumstances (like a change in tax law or a beneficiary’s special needs) arise. Additionally, Arizona law allows modification if all beneficiaries consent and the change does not conflict with a material purpose of the trust (such as a spendthrift clause or an age-based distribution requirement).
Can an irrevocable trust ever be changed?
Yes, irrevocable trusts can be changed under specific Arizona statutes. While the settlor (creator) generally cannot change it unilaterally, it can often be modified through a court order, consent of all beneficiaries, or a process called “decanting” if the terms allow it.
How is a trust terminated?
To terminate a trust, the trustee must distribute all remaining assets to the beneficiaries and perform a final accounting. For irrevocable trusts, this often requires either the unanimous consent of all qualified beneficiaries or a court order determining that the trust’s purpose has been fulfilled or is no longer economically feasible.
What are the trust modification requirements under Arizona law?
Arizona law (A.R.S. § 14-10411 and similar statutes) typically requires the consent of the qualified beneficiaries and, in many cases, a finding that the modification is consistent with the settlor’s intent. If the settlor is alive, they may also need to consent; if deceased, the court often weighs the proposed change against the “material purpose” of the trust.
How does decanting a trust work?
Decanting is the process of “pouring” the assets from an old, outdated trust into a new trust with more favorable terms. The trustee uses their discretionary distribution powers to move the assets, effectively updating the administrative terms or governing law without necessarily needing court involvement provided all statutes are complied with.
What are the steps in the trust modification process?
The process typically begins with reviewing the trust document to identify the issue, followed by obtaining written consent from all qualified beneficiaries. If unanimous consent is not possible or the trust is irrevocable, a petition is filed with the court, followed by a hearing where a judge reviews the request.
Does trust modification always require court approval?
No, not always. If the trust is revocable, the settlor can modify it at any time without court approval. For irrevocable trusts, a Non-Judicial Settlement Agreement (NJSA) signed by all interested parties can often modify administrative terms without a judge, provided the change doesn’t violate a material purpose of the trust.
What happens when the settlor is deceased?
When the settlor passes away, a revocable trust typically becomes irrevocable, meaning the power to amend it freely is lost. However, the trustee or beneficiaries can still petition the court to modify or terminate the trust if there are “unanticipated circumstances” or if the trust is no longer serving its intended purpose effectively.
What are the legal reasons to end a trust?
Common legal grounds for ending a trust include the fulfillment of the trust’s objectives (e.g., a child reaches age 25), the trust value becoming too low to justify administration costs (uneconomic trust), or the purpose becoming illegal or impossible to achieve.
What is the “Uneconomic Trust” rule in Arizona?
Under Arizona law, if the value of a trust’s assets falls below the statutory threshold (currently $100,000 in Arizona) and the cost of administration outweighs the benefits, the trustee may terminate the trust. The trustee must notify beneficiaries and distribute the assets according to their shares.
Can a beneficiary block a trust modification?
Yes, a beneficiary can object to a proposed modification. If a beneficiary refuses to consent, the proponent of the change must usually go to court. The judge will then decide if the modification is valid and ensures that the dissenting beneficiary’s interests are adequately protected.
Do I need a lawyer for trust modification?
Yes, hiring an experienced attorney is critical because trust laws are complex and technical errors can lead to trustee liability or tax penalties. A lawyer ensures that any modification or termination complies with Arizona statutes and properly protects the trustee from future lawsuits.
How long does the modification process take?
The timeline varies significantly based on cooperation. If all beneficiaries agree and sign a Non-Judicial Settlement Agreement, it can take a few weeks. If the matter is contested or requires court approval, the process can take several months to resolve.
