Can an Arizona Irrevocable Trust Ever Be Changed?
From its name, it is reasonable to assume that an irrevocable trust can never be changed. However, there are a few different circumstances that allow a trust originally intended as irrevocable to be altered, dissolved or replaced. If you believe that specific instructions left by a trust settlor should no longer be followed, you should speak with a qualified attorney about whether modification is possible under Arizona law.
Generally, when someone looks to alter an irrevocable trust, a key is whether the proposed revision conforms with the material purposes of the legal instrument. Specific situations that can justify a change include the following:
- Consent of beneficiaries — Pursuant to Section 14-10411 of the Arizona Revised Statutes, courts can approve a modification to noncharitable irrevocable trust when all beneficiaries agree to the change, and the revision does not conflict with a material purpose of the trust. Similarly, a court might also approve a revision even when there is not unanimous agreement, as long as the interests of any nonconsenting beneficiaries are protected.
- Decanting — Should a trustee have the requisite authority, they might transfer assets from an irrevocable trust into a newly created trust that has the same beneficiaries. This is referred to as “decanting.” In some cases, this is done to correct a mistake the settler made in drafting the trust or to ease the distribution of assets. You might also consider this if a beneficiary has special needs or there is a concern about exposure of trust assets to creditors.
- Judicial determination — There could be instances where the best way to accomplish the objectives of the settlor is to alter the trust itself. Arizona Revised Statutes Section 14-10412 says that when circumstances arise that the settlor did not anticipate, courts may modify or terminate a trust in order to further the purposes of the instrument. A judge can also modify the administrative terms of a trust if they are impractical or wasteful.
If an irrevocable trust no longer fits today’s realities, a knowledgeable Arizona wills and trusts lawyer can assess the document’s material purposes, identify all necessary parties and advise whether beneficiary consent, a court petition or decanting offers the safest, most efficient path to the resolution you seek.
