In California, a Trust Is Not a Legal Entity

Executive Summary

Under California law, a trust is not a legal entity. It is a property relationship: one person (the trustee) holds property at the request of another (the settlor) for the benefit of a third (the beneficiary). The trust itself has no legal personality. It cannot own property, enter into contracts, retain counsel, sue or be sued, or hold a bank account in its own name. Everything that appears to be done “by” or “for” the trust is in fact done by the trustee, acting in that capacity.

This has direct consequences in four areas that practitioners and clients regularly get wrong:

1. Title and property transfers — property is transferred to the trustee, not to the trust; a deed or account titled in the trust’s name without reference to the trustee creates a title defect
2. Legal representation — the attorney represents the trustee, not the trust and not the beneficiaries; confusion about this creates real professional responsibility exposure
3. California vs. other states — the non-entity rule is California’s position; many other states follow an entity theory under which a trust has independent legal status; the distinction matters when property or parties are in multiple jurisdictions
4. Federal tax treatment — the IRS treats a trust as a taxable entity for federal income tax purposes, requiring its own Employer Identification Number once the trust becomes irrevocable; this is a federal tax classification rule, not a statement about the trust’s legal nature under California property law

Governing Law

The Non-Entity Rule: California Common Law and Probate Code

California follows the traditional common law view: a private express trust is not a legal entity but a fiduciary relationship. The trustee holds legal title to trust property in their own name, in their capacity as trustee. The beneficiaries hold equitable title. The “trust” is shorthand for this set of legal relationships — it is not a separate legal person distinct from the parties who constitute it.

This rule is codified throughout the California Probate Code, which consistently speaks of the trustee’s duties, the trustee’s powers, and the trustee’s liability — not the trust’s. When the California Probate Code says a trustee “shall” do something, it means the human or institutional person acting as trustee bears the obligation, personally in their fiduciary capacity.

The practical consequences of the non-entity rule are explored in each section below.

The Entity Theory in Other States

California’s non-entity position is not universal. Many states — including Delaware, South Dakota, Nevada, and others that have developed sophisticated trust law — treat trusts as legal entities with independent legal existence separate from the trustee. Under entity theory jurisdictions, a trust can hold property, sue and be sued, and enter contracts in its own name.

The Uniform Trust Code (UTC), adopted in whole or part by the majority of U.S. states, moves toward entity treatment in some respects, particularly in litigation. Under the UTC and statutes modeled on it, a trust may be a party to legal proceedings in its own name. California has not adopted the UTC.

The distinction matters whenever a California trust has contacts with another state — property located elsewhere, a trustee who has moved, or a beneficiary asserting rights under another state’s law. Practitioners should not assume that California’s non-entity rule governs in all contexts; choice-of-law analysis may determine that another state’s entity-treatment rules apply to a particular dispute or transaction.

Federal Tax Treatment: I.R.C. §§ 641, 671–679; Treas. Reg. § 301.6109-1

The Internal Revenue Code treats a trust as a separate taxable entity for federal income tax purposes. This is a federal tax classification — it does not change the trust’s legal nature under California property law, but it has significant practical consequences.

A trust that is not wholly disregarded as a grantor trust must file its own federal income tax return (Form 1041) and report income, deductions, and distributions. To do so, it must have its own Employer Identification Number (EIN), obtained by the trustee on behalf of the trust by filing IRS Form SS-4.

The trigger for EIN requirement depends on the trust’s tax classification:

• Revocable grantor trust (settlor retains control): treated as a disregarded entity during the settlor’s lifetime; the settlor’s own Social Security Number is used; no separate EIN is required while the trust is fully revocable
• Irrevocable trust (including a revocable trust that becomes irrevocable at the settlor’s death): must obtain its own EIN; the trust is a separate taxpayer from the moment of irrevocability
• Irrevocable grantor trust (settlor has transferred assets but retains certain powers under I.R.C. §§ 671–679): income is still reported on the settlor’s individual return, but the trust itself may still require an EIN for institutional purposes

The IRS’s treatment of a trust as a taxable entity is a federal tax rule, not a grant of legal personhood under state law. The same trust that requires its own EIN for federal tax purposes still has no legal personality under California law and cannot hold title to property in its own name.

⚠️ CRITICAL DISTINCTION: The IRS requiring a trust to have its own EIN does not mean the trust is a legal entity under California law. These are parallel legal frameworks — federal tax classification and California property law — operating independently. A trust can simultaneously be a separate taxable entity for IRS purposes and a non-entity fiduciary relationship for California property and professional responsibility purposes.

Where the Non-Entity Rule Has Direct Practical Consequences

1. Property Title and Deed Mechanics

Because a trust has no legal personality under California law, it cannot hold title to real property. The trustee holds title. When real property is transferred into a trust — whether by the settlor at formation or by a third party — the deed must name the trustee, not the trust:

Correct: “Jane Smith, Trustee of the Smith Family Trust dated January 1, 2020”

Incorrect: “The Smith Family Trust” (no trustee named)

Also incorrect: “Jane Smith, Trustee” (no trust identified — this is personal, not fiduciary title)

A deed that names only the trust, without identifying the trustee, creates a title defect. The trust cannot hold property; if the trustee is not identified, there is no legal person in whom title vests. Title companies regularly flag this defect and will require a corrective deed before insuring a subsequent transfer.

The same rule applies to financial accounts, brokerage accounts, and other titled assets. When a bank or brokerage opens a trust account, the account should be held in the name of the trustee “as trustee of” the named trust. Many financial institutions use shorthand in their systems — “The Smith Family Trust” — but the underlying account agreement and legal documentation should reflect the trustee’s name in fiduciary capacity.

When the trustee changes — because the original trustee has resigned, died, or been removed — the successor trustee steps into the same legal position. Title does not need to be re-recorded to reflect the new trustee’s name for the title to be valid; the successor trustee’s authority derives from the trust instrument, not from the deed. However, a new deed of confirmation naming the successor trustee is often recorded as a practical matter to avoid confusion and facilitate future transactions.

📌 PLANNING NOTE: At trust formation, the funding process — transferring titled assets into the trust — must use correct vesting language on every deed, account form, and transfer document. “Into the trust” is not a legally precise instruction; the correct instruction is “to [Trustee Name], as Trustee of the [Trust Name] dated [Date].” Attorneys who draft trusts but do not supervise funding create documents whose legal effectiveness depends entirely on whether the client’s financial institutions and title company used correct language.

2. Legal Representation: Who Is the Client?

Because a trust is not a legal entity, an attorney cannot represent a trust. The attorney represents the trustee — in their capacity as trustee. This is the explicit rule under California professional responsibility law:

“At least insofar as private express trusts are concerned, the client under California law is the fiduciary or fiduciaries and not the estate or trust as a whole, and not a fiduciary and beneficiaries as joint clients.” — Shaver TW (Ed.), Guide to the California Rules of Professional Conduct for Estate Planning, Trust and Probate Counsel, 4th ed. (California Lawyers Association, 2020), p. 161.

This is materially different from the rule governing corporations. Under California Rules of Professional Conduct Rule 1.13, an attorney representing an organization represents the organization itself — the entity — not any individual officer or director. An organization is a legal entity; an attorney retained by a corporation represents the corporation as client. A trust is not an entity; an attorney retained by a trustee represents the trustee as client, in their fiduciary capacity.

The practical consequence most likely to generate confusion: beneficiaries frequently assume that the attorney who drafted the trust, or who advises the trustee in administration, represents their interests as well. They do not. The attorney’s client is the trustee. The attorney’s duties of confidentiality, loyalty, and candor run to the trustee, not to the beneficiaries.

If a dispute arises between the trustee and the beneficiaries, the trustee’s attorney represents the trustee. The beneficiaries must retain their own counsel. An attorney who attempts to represent both the trustee and beneficiaries simultaneously faces a conflict of interest that is very difficult to waive — their duties to each client are structurally adverse once a dispute exists.

The successor trustee rule: because the attorney represents the trustee in their fiduciary capacity — not as an individual — confidential communications between the former trustee and the attorney are not protected against disclosure to a successor trustee. When a trustee is replaced, the attorney-client relationship (in the fiduciary capacity) follows the office, not the person. A successor trustee stepping into the role is entitled to access the communications their predecessor had with trust counsel, because those communications belong to the trust administration, not to the former trustee personally. The former trustee retains no personal privilege over communications made in their fiduciary capacity.

3. California vs. Other States: Why Jurisdiction Matters

California’s non-entity rule creates practical complications when a trust has multi-state connections. Common scenarios:

Real property in another state: A California trust that holds real property in a state following entity theory may find that the other state’s courts and title companies treat the trust differently than California does. A deed recorded in Nevada or Delaware naming “The Smith Family Trust” as grantee may be valid under that state’s entity-theory law, even though the same deed would create a title defect in California.

Litigation in a non-California court: In a UTC-based jurisdiction, a trust may be a proper party to a lawsuit in its own name. In California, a lawsuit involving trust assets must name the trustee as a party, not the trust. A California attorney litigating in a multi-state trust dispute must analyze which state’s procedural rules apply to the question of parties.

ERISA trusts and federal law: ERISA-governed plans (pension trusts, 401(k) plans) follow federal entity-theory rules under which the trust has legal capacity independent of California law. The non-entity rule is a California common law rule for private express trusts; it does not govern ERISA trusts, business trusts, or statutory entities that happen to use the word “trust.”

4. Federal Tax Entity Treatment and the EIN Requirement

When a revocable living trust becomes irrevocable — typically at the settlor’s death — the trustee must promptly obtain an EIN for the trust. This is a tax compliance obligation with immediate practical consequences:

• Financial institutions will not transfer account control to the successor trustee without an EIN
• Form 1041 (the trust’s income tax return) cannot be filed without an EIN
• Distributions from the trust to beneficiaries are reported under the trust’s EIN on Schedule K-1

The EIN is obtained by the trustee on behalf of the trust, using IRS Form SS-4. The application identifies the trust by name and date, and identifies the trustee as the responsible party. The EIN is associated with the trust — it follows the trust, not the individual trustee — and remains valid if the trustee is replaced.

This federal tax entity treatment coexists with California’s non-entity rule without contradiction. For tax purposes, the IRS needs a unit of account — a taxable entity — to which it can assign income and filing obligations. The trust is that unit for federal income tax purposes. For title, professional responsibility, and litigation purposes under California law, the trust remains a fiduciary relationship, not a legal person.

Practice Notes

Deed and Transfer Drafting

• Always identify the trustee by name and the trust by name and date in vesting clauses: “[Name], Trustee of the [Trust Name] dated [Date]”
• When preparing deeds to fund a trust, confirm that the vesting language reflects the trustee, not merely the trust name
• If a deed is discovered naming only the trust without the trustee, a corrective deed should be recorded before the property is transferred, refinanced, or placed into escrow

Tax Administration

• When a revocable trust becomes irrevocable, obtain the EIN as the first administrative step — before attempting to transfer accounts, open a trust administration account, or file any return
• For grantor trusts that remain irrevocable but where income is still reportable on the settlor’s return, obtain the EIN even if it will not be used for Form 1041 filing; financial institutions will require it
• Confirm with the trust’s CPA at each calendar year whether the trust’s filing status (grantor vs. non-grantor, simple vs. complex) has changed, as the reporting obligations shift accordingly

Professional Responsibility

• In any engagement involving a trust, confirm in the engagement letter who the client is: the trustee, in their fiduciary capacity
• Advise beneficiaries at the outset — and confirm in writing — that the attorney represents the trustee and not the beneficiaries; beneficiaries should obtain independent counsel for any matter involving their individual interests
• When advising a trustee facing potential removal, analyze promptly whether the communications made in the fiduciary capacity may be accessible to a successor trustee and advise the client accordingly

⚠️ COMMON ERROR: Documents and correspondence that refer to the trust as if it were a person — “the trust retained counsel,” “the trust owns the property,” “the trust filed a return” — are imprecise in ways that occasionally produce legal errors. Deeds titled in the trust’s name without a trustee are the most common and most consequential. The precision required is not merely terminological; it reflects the actual legal structure of the relationship and, in the case of title, determines who has the legal capacity to transfer the property.
