On a trust document, bank statement, or recorded deed, “u/a” means under agreement. It tells you the assets are held in a living trust created by a written agreement between a grantor (the person who set the trust up) and a trustee (the person responsible for managing it). You’ll almost always see it followed by a date and the trust’s name, forming the official title used to hold accounts and property.
What “Under Agreement” Signals
When a trust is labeled u/a, the trust came into existence through a standalone written contract signed during the grantor’s lifetime. In legal terms, that makes it an inter vivos trust: it was created and became effective while the grantor was still alive, as opposed to a trust that springs out of a will after death. The agreement itself is a private document. No court creates it, and no court supervises the trustee’s ordinary administration of it.
The “agreement” part carries a specific traditional meaning that often confuses people. Historically, u/a signals that the grantor and the trustee are two different people: the grantor transfers assets to a separate trustee who then manages them under the written terms.1Department of the Treasury, Bureau of the Fiscal Service. FS Publication 0049 – Questions and Answers About Trusts In actual practice, though, plenty of estate planning attorneys use “u/a” on revocable living trusts where the grantor initially acts as their own trustee. Local convention varies. So if your own trust is tagged u/a, it does not automatically mean someone else is running your assets.
The Date That Follows U/A
After the abbreviation you’ll see a calendar date, often written as “u/a 03/15/2020” or sometimes expanded to “u/a/d” for “under agreement dated.” That’s the execution date — the day the grantor and trustee signed the original trust instrument.
The date is doing real work. Banks and brokerages use it to match an account to the correct trust document on file. When one person has set up more than one trust over the years, the date distinguishes the current arrangement from an older one. Compliance teams cross-reference it against the trust certificate or full agreement provided when the account was opened. Without that date, an institution dealing with similarly named trusts could freeze an account until the ambiguity is cleared up.
Amendments usually don’t change the date. If the grantor tweaks a provision or swaps out a trustee, the original execution date stays on account titles. A full restatement — where the entire document is rewritten and replaced — is a bigger change, but even then the original name and date typically carry forward. That means a restated trust can supersede the old terms without forcing you to re-title every asset.
How U/A Appears on an Account or Deed
When you move property into a trust, the ownership record changes from your personal name to the trust’s official title. A brokerage account might read “Jane Smith, Trustee, The Smith Family Trust u/a 03/15/2020.” A recorded deed uses similar language in the grantee line.
The order is predictable: trustee’s name first, then the word “Trustee,” then the trust name, then u/a and the date. That ordering exists so third parties can figure out quickly who is authorized to act without reading the entire trust agreement. The trustee’s name up front tells a bank who should be signing. The trust name and date tell them which document governs. If someone other than the named trustee tries to transact, the institution knows to ask questions.
What the title also tells anyone reviewing the record is that the named trustee doesn’t own the assets personally. They hold them in a fiduciary capacity under the terms of that specific agreement. That distinction matters for creditor protection, tax reporting, and keeping the assets out of probate.
When a successor trustee eventually steps in, the trustee portion of the title has to be updated on each account. The trust name and the u/a date stay the same. Only the name of the person serving as trustee changes.
U/A vs. U/W vs. U/D/T
You’ll run into two related abbreviations, and each one tells you something different about how the trust was created.
- U/A (under agreement) is a living trust formed by a written agreement between a grantor and trustee. It takes effect as soon as it’s signed and operates outside probate.
- U/W (under will) is a testamentary trust created inside a will. It doesn’t exist until the grantor dies and a court-appointed representative is in place, and the will has to go through probate before the trustee can begin managing anything.1Department of the Treasury, Bureau of the Fiscal Service. FS Publication 0049 – Questions and Answers About Trusts
- U/D/T (under declaration of trust) is a living trust where the grantor and trustee are the same person. Instead of a two-party agreement, the grantor declares themselves trustee of their own assets. This is a common structure for revocable living trusts where someone wants to stay in direct control.
The practical split between u/a and u/d/t comes down to who holds the management power on paper. With u/d/t one person wears both hats. With u/a the trust instrument contemplates a separation between the person who created the trust and the person running it. When you open or re-title an account, the institution may ask which designation applies, because it affects whose signature they’ll accept.
What U/A Does Not Tell You
The abbreviation itself only identifies how the trust was formed. It doesn’t tell you whether the trust is revocable or irrevocable — that comes from the terms of the agreement, not from the three letters on the title. It also doesn’t tell you whose taxpayer identification number is attached to the account. A revocable u/a trust set up by a living grantor is usually treated as a grantor trust for tax purposes, meaning income is reported under the grantor’s own Social Security number rather than a separate EIN.2Internal Revenue Service. Instructions for Form SS-4 (12/2025) Once the grantor dies and the trust becomes irrevocable, the trust files its own income tax return and issues K-1s to beneficiaries for their share of the income.3Internal Revenue Service. Instructions for Form 1041 and Schedules A, B, G, J, and K-1 (2025)
In short, u/a is a label about origin. It tells you the trust was built from a written agreement during the grantor’s lifetime, and the date next to it points to the exact document that controls. For anything beyond that — who can be trustee, what the beneficiaries receive, whether the terms can still be changed — you need to look at the agreement itself.
