Key Takeaways

• Decanting lets a trustee pour the assets of one irrevocable trust into a new trust with different (usually improved) terms.
• California has adopted a decanting statute (effective 2019) that authorizes it under specified conditions.
• It generally requires a trustee with discretion to distribute trust principal, and does not require court approval or beneficiary consent.
• The trustee must give notice to interested parties, and decanting cannot defeat the trust’s material purpose or exceed what the law allows.
• Decanting can fix outdated terms, correct drafting problems, or improve administration — but it’s powerful and can itself become the subject of a dispute.

What Decanting Is

The name is a metaphor: just as you might decant wine from one bottle to another to leave the sediment behind, a trustee can “decant” the assets of an irrevocable trust into a new trust with cleaner, better, or updated terms. It’s a way to effectively modify an irrevocable trust without going to court — the trustee, exercising a power to distribute trust property, distributes it into a new trust instead of outright to a beneficiary.

This is a relatively modern and powerful tool. For trusts that have become outdated, contain drafting errors, or no longer fit the family’s circumstances, decanting can offer a fix that’s faster and less expensive than a court modification. California adopted a comprehensive decanting statute that took effect in 2019, giving trustees a clear framework for when and how they can decant. Understanding it matters both for trustees considering it and for beneficiaries who may be affected by — or wish to challenge — a decanting.

How California Decanting Works

California’s decanting law authorizes an authorized fiduciary — generally a trustee who has discretion to distribute the trust’s principal — to distribute the trust property to a new (or modified) trust, subject to conditions. The breadth of what the trustee can change in the new trust generally depends on how much discretion the trustee has under the original trust: a trustee with broad, “expanded” distribution discretion has more latitude to alter terms, while a trustee with more limited discretion can make fewer changes.

Critically, decanting under the statute generally does not require court approval or the beneficiaries’ consent. That’s what makes it efficient — and also what makes it powerful and, to some beneficiaries, concerning. The trustee acts on their own authority, within the statute’s limits. There are important guardrails, though: the new trust generally can’t be used to benefit the trustee improperly, can’t exceed the law’s limits, must respect certain protected interests, and can’t be used to accomplish what the law forbids.

The Notice Requirement

Although decanting doesn’t require beneficiary consent or court approval, it isn’t done in secret. California’s statute requires the trustee to give advance notice of the proposed decanting to interested parties — typically the settlor (if living), the beneficiaries, and others the statute specifies — generally a set period before the decanting takes effect.

That notice is the beneficiaries’ protection and their opportunity. It tells them a decanting is coming, lets them review what’s changing, and gives them the chance to object or seek court intervention if they believe the decanting is improper or exceeds the trustee’s authority. So while beneficiary consent isn’t required, beneficiary awareness is built in — and a beneficiary who has concerns about a proposed decanting needs to act within the notice window rather than after the fact.

What Decanting Can — and Can’t — Do

Decanting is flexible, but it isn’t unlimited. Common legitimate uses include:

• Fixing outdated administrative terms — modernizing trustee powers, governing law, or administrative provisions.
• Correcting drafting errors or ambiguities in the original trust.
• Adapting to changed circumstances — adjusting for tax-law changes or family developments the settlor didn’t anticipate.
• Adding protective provisions — such as a special-needs structure for a beneficiary who now needs one, or stronger spendthrift protection.
• Consolidating or dividing trusts for better administration.

But the statute draws lines. Decanting generally cannot be used to defeat the trust’s material purpose in impermissible ways, to add the trustee as a beneficiary or otherwise benefit the trustee improperly, to remove certain protected or vested interests beyond what the law allows, or to accomplish indirectly what the law prohibits directly. A trustee who decants outside these limits acts beyond their authority — which is exactly the kind of overreach a beneficiary can challenge.

When Decanting Becomes a Dispute

Because decanting lets a trustee change a trust without consent or court approval, it can itself become the subject of litigation. Beneficiaries may challenge a decanting on grounds such as:

• The trustee lacked the required discretion to decant at all.
• The decanting exceeded the statutory limits — changing things the law doesn’t permit, or harming protected interests.
• The decanting improperly benefited the trustee or favored some beneficiaries over others in a way the law forbids.
• The notice was defective, depriving beneficiaries of their chance to respond.
• The decanting breached the trustee’s fiduciary duties — for instance, if it wasn’t in the beneficiaries’ interest.

A beneficiary who receives a decanting notice and suspects overreach should evaluate it promptly, because the notice window is the natural time to object. Conversely, a trustee considering decanting should confirm they have the authority and stay within the statutory lines — because a decanting done wrong can be challenged, unwound, and expose the trustee to liability.

Decanting is powerful — and powerful tools draw scrutiny. Whether you’re decanting or questioning one, Bay Legal can help you get it right. For guidance on your specific situation, call (650) 668-8000 or schedule a consultation at baylegal.com/contact.

Decanting Versus Court Modification

It’s worth distinguishing decanting from the court-based modification or termination of a trust. Modification generally requires a court petition (and often beneficiary consent or a showing of changed circumstances), and the court oversees the change. Decanting is the trustee’s own exercise of a distribution power, generally without court involvement, relying on the trustee’s discretion and the statute’s authority. Each has its place: decanting is faster and avoids court but depends on the trustee having sufficient discretion and staying within limits, while court modification provides court approval and can reach changes decanting can’t. Choosing between them — or deciding whether either is appropriate — depends on the trust, the goal, and the trustee’s powers.

How This Fits Together

Decanting is one way to change an irrevocable trust, distinct from court-based modification or termination and from interpreting a trust. It’s an exercise of trustee power that, if misused, can lead to breach and removal claims, and it runs through notice rather than the §17200 petition unless challenged. 

Frequently Asked Questions

What is trust decanting in California?

It’s a trustee’s distribution of an irrevocable trust’s assets into a new trust with different terms, effectively modifying the trust without court approval. California’s decanting statute, effective in 2019, authorizes it under specified conditions.

Does decanting require court approval or beneficiary consent?

Generally no. Decanting under California’s statute is the trustee’s own exercise of a distribution power and doesn’t require court approval or beneficiary consent — but the trustee must give advance notice to interested parties, who can object.

Who can decant a trust?

Generally an authorized fiduciary — a trustee with discretion to distribute the trust’s principal. How much the trustee can change in the new trust depends on how broad that distribution discretion is.

What are the limits on decanting?

Decanting can’t defeat the trust’s material purpose in impermissible ways, improperly benefit the trustee, remove certain protected interests beyond what the law allows, or accomplish what the law forbids. The trustee must also satisfy the notice requirements.

Can a beneficiary challenge a decanting?

Yes. A beneficiary can challenge a decanting on grounds such as the trustee lacking authority, exceeding statutory limits, improperly benefiting the trustee, defective notice, or breaching fiduciary duties. The notice window is the natural time to raise concerns.
