To name a trust in a lawsuit, you sue the trustee in their fiduciary capacity, not the trust itself. The caption should give the trustee’s full legal name, state that they are being sued as trustee, and identify the trust by its complete name and date, for example: Jane Miller, as Trustee of the Miller Family Irrevocable Trust dated May 1, 2015. Getting any of those three elements wrong can cost you filing fees, delay the case, and in some situations let the statute of limitations run out before the mistake is fixed.
Why the Trustee Is the Defendant
A trust is not a corporation. In almost every state, it is a fiduciary relationship in which the trustee holds legal title to property for the benefit of someone else. Because it is a relationship rather than a standalone entity, it has no capacity to appear in court on its own.
Federal Rule of Civil Procedure 17(b) leaves capacity for trusts to the law of the state where the court sits, and the traditional rule applies almost everywhere: the trustee is the proper party.1Legal Information Institute. Rule 17 – Plaintiff and Defendant; Capacity; Public Officers Under the framework most states have adopted through the Uniform Trust Code, the trustee is obligated to defend claims directed at the trust, which makes the trustee the real party in interest.
The Capacity Phrase Controls Which Assets Pay
Naming the trustee is only half the job. You also have to say you are suing them in their capacity as trustee, not as a private individual. That short phrase decides where a judgment gets paid from.
Sue “Jane Doe, as Trustee of the Doe Family Trust” and any judgment attaches to trust assets. Sue just “Jane Doe” and you are aiming at her personal bank accounts, her home, and her retirement savings. If your dispute is really about how trust property was managed, a court will likely dismiss a complaint filed against the trustee personally because you have sued the wrong capacity. If the statute of limitations expires while you scramble to refile, the claim may be gone.
The Uniform Trust Code reinforces the same line from the other direction: a trustee who properly discloses their fiduciary capacity in contracts is generally shielded from personal liability on those dealings. That shield only works if the lawsuit itself reflects the same distinction.
How to Format the Caption
The caption is the heading at the top of the complaint that tells the court who is suing whom. For a trust, it has to do three things: name the trustee, state their role as trustee, and identify the specific trust.
Jane Miller, as Trustee of the Miller Family Irrevocable Trust dated May 1, 2015
Every element is doing work. “Jane Miller” tells the process server who to deliver the papers to. “As Trustee” establishes the representative capacity and directs the case at trust assets. “Miller Family Irrevocable Trust dated May 1, 2015” pins down the specific trust, which matters if the same person serves as trustee for more than one.
Institutional Trustees
Banks and trust companies get named the same way, using the entity’s legal name followed by the trustee title and the full trust name:
First National Bank, as Trustee of the Miller Family Irrevocable Trust dated May 1, 2015
Use the legal name that appears on the trust instrument, not a trade name or abbreviation. A bank doing business as “First National” but chartered as “First National Bank, N.A.” should appear under the chartered name.
Co-Trustees
When a trust has more than one trustee, list each one with the full trustee designation:
Jane Miller and Robert Miller, as Co-Trustees of the Miller Family Irrevocable Trust dated May 1, 2015
A court order that binds only one of two co-trustees may not be enforceable against the trust as a whole, because both share management authority. If one co-trustee is an individual and the other is an institution, both still appear.
Revocable Trusts With a Grantor-Trustee
The most common estate-planning trust is a revocable living trust, where the person who created the trust also serves as trustee during their lifetime. You still name the grantor in their trustee capacity. The assets are effectively the grantor’s own, and a judgment against them as trustee reaches the same pool a personal judgment would, but the capacity designation still matters for procedural correctness. Courts have dismissed complaints that named a revocable trust directly rather than the grantor-trustee.
Information You Need Before You Draft
Two things have to be nailed down before you file: the exact legal name of the trust and the full name of every current trustee.
Trust names typically include the creator’s name and the date the document was signed, in a format like “The John B. Doe Revocable Living Trust dated March 15, 2010.” An abbreviated version like “the Doe Trust” invites an objection that you named the wrong trust, especially where a family has created more than one over the years. Use the full name as it appears in the trust document.
All current trustees should be named. Identifying them upfront avoids amending the complaint later when the omission surfaces.
Where to Find the Names
The trust instrument is the most reliable source. Beneficiaries can request relevant information from the trustee, including material identifying who currently serves. Many states allow the trustee to provide a certification of trust in place of the full document. That certification is a shorter instrument confirming the trust exists, identifying the current trustee, stating whether the trust is revocable or irrevocable, and describing the trustee’s authority, without revealing who inherits what.
If you are not a beneficiary and cannot get cooperation, public records fill the gap. When a trust owns real estate, the recorded deed lists both the trustee’s name and the trust name. County recorder offices and online property databases are the fastest route. Court records from prior litigation involving the trust can also identify the current trustee.
Serving the Trustee
Once the complaint names the trustee correctly, it has to be delivered through formal service of process. Mailing a copy to a P.O. box tied to the trust does not count. Due process requires that the trustee receive actual notice.
Under the Federal Rules of Civil Procedure, anyone at least 18 years old who is not a party to the lawsuit can serve the summons and complaint, and state service procedures may be followed as well.2Legal Information Institute. Rule 4 – Summons Most plaintiffs hire a professional process server or use the county sheriff. The server physically hands the papers to the trustee.3Legal Information Institute. Service of Process
If the trustee is hard to locate, courts may permit substituted service, typically leaving the papers with another adult at the trustee’s home or place of business and then mailing a copy. The rules vary by state.4Legal Information Institute. Substituted Service After service, the server files proof with the court describing what was served, on whom, and when and where.
Fixing a Naming Mistake
Mistakes happen. A plaintiff might name the trust itself instead of the trustee, use the wrong trustee’s name, or leave out the capacity designation. Federal Rule of Civil Procedure 15(c), and most state analogs, allow amendment. Timing decides whether the fix actually works.
Rule 15(c) governs relation back, the mechanism that lets an amended complaint take the filing date of the original. For a corrected party name to relate back, three conditions must be met: the amendment must arise from the same facts as the original complaint; the correct party must have received notice of the lawsuit soon enough to avoid prejudice in defending; and the correct party must have known, or should have known, that they would have been named but for the mistake.5Legal Information Institute. Rule 15 – Amended and Supplemental Pleadings
Courts distinguish a misnomer from a misidentification. A misnomer means you sued the right person and wrote their name or title wrong. Courts routinely allow relation back, because the intended defendant clearly knew they were the target. A misidentification means you sued the wrong person entirely, perhaps a former trustee replaced years ago. That is much harder to fix, because the actual current trustee may never have received notice during the original filing window. If the statute of limitations has already run when the error surfaces, a misidentification can end the case.
When the Trustee Changes During the Case
Trustees resign, get removed, become incapacitated, or die. When that happens mid-lawsuit, the case does not automatically shift to the successor. Trust litigation requires a formal motion to substitute the new trustee as a party.
Federal Rule of Civil Procedure 25(c) covers the transfer. The lawsuit can continue against the original trustee unless the court orders the successor substituted or joined. The party seeking substitution files a motion, serves it on existing parties through normal channels, and serves the successor trustee through the same formal service methods used for any new party.6Legal Information Institute. Rule 25 – Substitution of Parties
A judgment entered against a former trustee who no longer controls trust assets may be unenforceable, and the successor can argue they were never a party and owe nothing. If you learn the trustee has changed, deal with the substitution right away.
