VII. STATUTORY BASIS FOR RELIEF

Petitioner relies on the following Arizona Trust Code grounds (check all that apply):

A. Modification or Termination by Consent — A.R.S. § 14-10411

☐ § 14-10411(A): The Settlor [is living and has consented / has consented in a writing attached as Exhibit C], and all beneficiaries have consented. The Trust may be modified or terminated without regard to whether modification or termination is inconsistent with a material purpose of the Trust.

☐ § 14-10411(B): The Settlor is not consenting (deceased or unable to consent), but all beneficiaries have consented, and continuance of the Trust is NOT necessary to achieve any material purpose of the Trust.

Facts supporting consent and absence of material-purpose obstacle: [________________________________]

B. Modification or Termination for Unanticipated Circumstances — A.R.S. § 14-10412

☐ § 14-10412(A): Because of circumstances not anticipated by the Settlor, modification or termination will further the purposes of the Trust. To the extent practicable, the modification must be made in accordance with the Settlor's probable intention.

☐ § 14-10412(B): Continuation of the Trust on its existing terms would be impracticable or wasteful or impair the Trust's administration.

Facts supporting unanticipated circumstances: [________________________________]

C. Cy Pres — Charitable Trusts — A.R.S. § 14-10413

☐ A particular charitable purpose has become unlawful, impracticable, impossible to achieve, or wasteful, and the Court may apply cy pres to modify or terminate the Trust by directing that the Trust property be applied or distributed, in whole or in part, in a manner consistent with the Settlor's charitable purposes.

Facts supporting cy pres: [________________________________]

D. Uneconomic Trust — A.R.S. § 14-10414

☐ § 14-10414(A) — trustee-initiated termination, trust value less than $100,000: The total value of the trust property is less than $100,000, the trustee has given notice to the qualified beneficiaries, and the trustee concludes that the value of the trust property is insufficient to justify the cost of administration.

☐ § 14-10414(B) — court modification/termination for any size trust: The Court may modify or terminate a trust or remove the trustee and appoint a different trustee if it determines that the value of the trust property is insufficient to justify the cost of administration.

Facts supporting uneconomic termination: [________________________________]

Current total value of trust property: $[__________]
Annual cost of administration (last 12 months): $[__________]

E. Reformation for Mistake — A.R.S. § 14-10415

☐ The Court may reform the terms of the Trust, even if unambiguous, to conform the terms to the Settlor's intention if it is proved by clear and convincing evidence that both the Settlor's intent and the terms of the Trust were affected by a mistake of fact or law, whether in expression or inducement.

Facts supporting reformation: [________________________________]

F. Modification for Tax Objectives — A.R.S. § 14-10416

☐ To achieve the Settlor's tax objectives, the Court may modify the terms of the Trust in a manner that is not contrary to the Settlor's probable intention. The Court may provide that the modification has retroactive effect.

Facts supporting tax-motivated modification: [________________________________]

G. Combination or Division of Trusts — A.R.S. § 14-10417

☐ Petitioner requests that the Court approve a combination of two or more trusts into a single trust OR a division of one trust into two or more separate trusts.

Facts: [________________________________]

ARIZONA PRACTICE NOTES

Arizona Trust Code framework. Arizona adopted the UTC (modified) effective January 1, 2009. Modification and termination provisions track UTC §§ 411-417 with some Arizona-specific variations — most notably the $100,000 threshold for trustee-initiated uneconomic termination in § 14-10414(A) and the requirement that consent modifications under § 14-10411 receive judicial approval.

Judicial approval required for § 14-10411 consent modifications. Unlike Washington's TEDRA mechanism, Arizona requires court approval for consent-based noncharitable irrevocable trust modifications. A nonjudicial settlement agreement under A.R.S. § 14-10111 explicitly excludes "modification or termination of a trust as otherwise permitted pursuant to the trust instrument" — meaning the §§ 14-10411 to 14-10417 statutory grounds are channeled through the courts.

Notice (A.R.S. § 14-1401). Method: personal delivery or first-class mail. Timing: at least 14 days before the hearing. Notice to the Arizona Attorney General is required under A.R.S. § 14-1401.01 for matters involving charitable interests.

Representation (A.R.S. §§ 14-1404 to 14-1407). Arizona has detailed representation rules covering basic effect, holders of general powers of appointment, fiduciaries and parents, and persons with substantially identical interests. Use these to bind minor, unborn, and unascertained beneficiaries without requiring a guardian ad litem in every case.

Guardian ad litem (A.R.S. § 14-1408). May be appointed when representation under §§ 14-1404 to 14-1407 is insufficient or there is a conflict of interest.

Uneconomic trust — $100,000 threshold. A trustee may, without court approval, terminate a trust with less than $100,000 in property after giving notice to qualified beneficiaries (A.R.S. § 14-10414(A)). For larger trusts, court action is required (A.R.S. § 14-10414(B)).

Cy pres notice. Notice to the Arizona Attorney General is mandatory for any cy pres proceeding involving a charitable trust.

Trustee's duty to inform (A.R.S. § 14-10813). Confirm that the Trustee has provided all required notices to qualified beneficiaries before filing — failure to do so may delay relief or create independent breach exposure.

Standing (A.R.S. § 14-10410(B)). A proceeding under §§ 14-10411 to 14-10417 may be commenced by a trustee or beneficiary; a charitable cy pres proceeding under § 14-10413 may also be commenced by the settlor.

Estate planning documents decide what happens to your property, your children, and your medical care when you cannot make those decisions yourself. Wills, trusts, powers of attorney, and health care directives each serve different purposes and each have to meet state law requirements for signing, witnessing, and notarization. A document that looks fine on the page but was not executed correctly can be rejected in probate, which is exactly when it is too late to fix.
