Brand change
The New Mexico Bank & Trust brand no longer exists. UMB Financial Corporation completed its acquisition of Heartland Financial USA (HTLF) on January 31, 2025, and announced on October 16, 2025 that the systems and brand conversion was finished — all former HTLF divisional banks, including New Mexico Bank & Trust, now operate as UMB Bank, N.A. The nmb-t.com website is dead and there is no New Mexico Bank & Trust phone number to call. Deposit accounts, CDs, IRAs, and POD designations are administered by UMB Bank: call UMB at 800-699-8702, or visit a New Mexico UMB branch. Trust and estate matters go to UMB Private Wealth Management — the Albuquerque Private Wealth Management Center at 320 Gold Ave SW, Suite 200 (800-545-6101), or UMB's trust and estate line at 800-862-6670. Effective October 2025.
New Mexico Bank & Trust is now part of UMB Bank. The procedures below reflect New Mexico Bank & Trust's accounts during the transition. View the UMB Bank estate planning page.

When an account holder at New Mexico Bank & Trust passes away, the next step depends on how the accounts were set up. Accounts with beneficiary designations or trust ownership transfer outside of probate. Accounts titled solely in the deceased's name require the estate's legal representative to work with New Mexico Bank & Trust's UMB Bank Customer Service (no separate deceased-account claims department is published) (800-699-8702) to access and distribute the funds.
Death claims at New Mexico Bank & Trust can be started through an online portal, which streamlines the initial notification and document upload. Phone and mail options are also available.
Death claim process
To file a claim after an account holder's death, here is what New Mexico Bank & Trust requires:
Filing a claim
- A certified copy of the death certificate
- Your government-issued photo ID
- The decedent's account number, or Social Security number
- Proof of your authority or standing — see the account-type branches below
- Joint account with right of survivorship — nothing has to be claimed. "After the death of a joint accountholder, all of the rights of the deceased account owner automatically pass to the surviving individual(s) who own the account." Notify UMB so the records are updated.
- Account with a payable-on-death direction — the POD beneficiary presents the death certificate and photo ID. A POD beneficiary is not an owner of the account before the death; the direction transfers the owner's interest at death, and UMB executes it "in accordance with applicable law."
- Individual account with no POD and no joint owner — this is an estate asset. The personal representative presents Letters Testamentary or Letters of Administration, or, for a small estate, the New Mexico successor affidavit (below).
- Trust-titled account — the successor trustee presents the trust agreement or certification of trust plus the death certificate, and steps in as the account's fiduciary.
- IRA — the named beneficiary claims directly. The IRA bypasses probate entirely, and UMB's setoff and security-interest rights do not reach an IRA.
Required Documents
- Certified copy of the death certificate
- Government-issued photo ID for the claimant
- The decedent's account number or Social Security number
- Letters Testamentary or Letters of Administration, for an individual account with no POD or joint owner
- Affidavit of Successor in Interest under NMSA 1978 § 45-3-1201 (notarized), where the estate's personal property is $50,000 or less and 30 days have passed since the death
- Trust agreement or certification of trust, plus successor-trustee identification, for a trust-titled account
What to know at this institution
The single most important fact for a New Mexico Bank & Trust claimant: there is no New Mexico Bank & Trust. The website is gone, the FDIC charter (Cert. 34726) went inactive on 08/18/2023, and UMB announced the brand conversion complete on October 16, 2025. Call UMB at 800-699-8702. Beyond that, four clauses of UMB's own Deposit Account Agreement shape the settlement and are worth reading before the first call. (1) Powers of attorney die with the principal: "the Bank will assume all powers of attorney terminate upon the principal's death." (2) Survivorship is automatic on a joint account: "all of the rights of the deceased account owner automatically pass to the surviving individual(s)." (3) UMB can take what it is owed first — a right of setoff against any account, exercisable without prior notice, plus a security interest it calls "superior to the claims of other creditors," neither of which reaches an IRA or HSA — and it can reverse federal or state benefit payments deposited after the decedent stopped being eligible for them. (4) An untouched account goes dormant at 24 months and access is restricted until someone re-establishes contact, so an inherited account should not be left sitting through a long probate. UMB publishes no deceased-account claim form and no dedicated estate-claims department or address for deposit accounts; the estate writes in through the branch, the 800-699-8702 line, or the Send A Message form. Small New Mexico estates should look hard at NMSA 1978 § 45-3-1201 before opening probate: $50,000 or less in personal property, 30 days after death, a notarized affidavit presented straight to the bank, and no court filing.
Prepare your letter of instruction to New Mexico Bank & Trust
New Mexico Bank & Trust accepts a claimant-drafted letter of instruction. We draft it for you — addressed to New Mexico Bank & Trust's verified claims department, with the documents it requires enclosed.
Build your letter of instructionHow long the process takes at New Mexico Bank & Trust: Joint accounts need no claim at all — the survivor already owns the balance. A POD beneficiary or a New Mexico § 45-3-1201 successor affidavit claimant can typically be paid once the documents are verified, though the affidavit cannot be used until 30 days after the death. An individual account with no POD and no joint owner waits on the probate court to issue Letters, which sets the timeline. UMB does not publish a service-level commitment for deceased-account claims. The most common reason for delays is missing or incomplete documentation, so submitting everything upfront is the best way to keep things moving.
Documentation required by New Mexico Bank & Trust includes Certified copy of the death certificate, Government-issued photo ID for the claimant, and The decedent's account number or Social Security number, along with additional paperwork that varies by account type. All death certificates and court documents must be certified copies.
Frequently asked questions
The account ownership and the beneficiary directions carried over — but the operating bank of record is now UMB Bank, N.A., and any NEW designation or change is made on UMB Bank forms. UMB's Deposit Account Agreement is what governs the account today: it allows a consumer account to be held as an individual account, a joint account with right of survivorship, a trustee account for the benefit of another party, or an individual or joint account with a payable-on-death direction, and it says "We may accept and execute payable-on-death designations on individual accounts and joint accounts in accordance with applicable law." If you are adding a POD beneficiary, retitling an account into a living trust, or naming a successor trustee, bring government-issued photo ID and the full trust agreement or a certification of trust to a New Mexico UMB branch and redo it on UMB paper.
Often, yes. Under NMSA 1978 § 45-3-1201, a successor of the decedent can collect the decedent's personal property — including money in a bank account — by presenting a notarized Affidavit of Successor in Interest directly to the holder of the property, when the estate's personal property is worth $50,000 or less and at least 30 days have passed since the death. Nothing is filed with a court; the New Mexico judiciary's Probate Self Help Guide names banks as exactly the kind of holder the affidavit is presented to. Two limits matter: the affidavit reaches personal property only, not real estate, and New Mexico has no statewide approved form — the self-help guide directs you to your local Probate Court for the form it uses. Take the affidavit, a certified death certificate, and your photo ID to a UMB branch.
It can, and its Deposit Account Agreement says so plainly. UMB has a right of setoff to "apply funds in any account you maintain with us to any debt that you owe the Bank or its affiliates," with no prior notice required, plus a separate security interest and lien in every account that the agreement describes as "superior to the claims of other creditors." So an unpaid UMB credit card, loan, or overdraft can reduce the deposit balance before anything reaches an heir — and on an unmatured Time Deposit (CD), UMB may also deduct the early withdrawal penalty its own setoff triggered. Two carve-outs protect retirement money: neither the setoff nor the security interest applies to an IRA or an HSA. Separately, UMB reserves the right to recover federal or state benefit payments — Social Security, VA, and the like — that were deposited after the decedent stopped being eligible for them, by setting off against any of the accounts. Do not spend a benefit payment that arrived after the date of death.
No. UMB's Deposit Account Agreement states: "Unless state law provides otherwise, the Bank will assume all powers of attorney terminate upon the principal's death." A power of attorney is a lifetime authority — it ends the moment the principal dies, and an agent who keeps signing checks or moving money afterward is acting without authority. The agreement also makes clear that an attorney-in-fact "is not, by virtue of the power, an owner of the account" and "has no right of survivorship in the account by virtue of that capacity." After the death, authority comes from somewhere else: survivorship on a joint account, a payable-on-death direction, the trust for a trust-titled account, Letters Testamentary or Letters of Administration from the probate court, or the NMSA 1978 § 45-3-1201 successor affidavit for a small estate.
New Mexico Bank & Trust's UMB Bank Customer Service (no separate deceased-account claims department is published) can be reached by phone at 800-699-8702 for questions throughout the claims process.
