Overview
BOK Financial is a top 25 U.S.-based financial services company headquartered in Tulsa, Oklahoma, with over $50 billion in assets. It operates under several regional brands, including Bank of Oklahoma, Bank of Texas, and Bank of Albuquerque. When an account holder passes away, the estate representative must notify BOK Financial (or the specific regional bank brand) to freeze accounts and begin the transfer process.
This guide covers the estate process for BOK Financial and its subsidiary banks. While BOK Financial offers professional estate settlement services for hire, this guide focuses on the administrative process for family members and executors handling the estate themselves.
BOK Financial operates primarily in the Southwest and Midwest (OK, TX, NM, AR, CO, KS, MO, AZ). State-specific probate laws in these jurisdictions will significantly influence your timeline and requirements.
This guide provides informational guidance only. It is not legal advice, and SwiftProbate is not a law firm. Laws and institutional procedures change — verify current requirements directly with BOK Financial and consider consulting a qualified attorney.
Notification Process
How to Notify BOK Financial of a Death
Step 1: Gather Initial Information
Before contacting the bank, have the following ready:
- Decedent's full legal name and date of birth
- Date of death
- Social Security number
- Account numbers (checking, savings, loans, or wealth management)
- Your name and relationship to the decedent
- A certified copy of the death certificate
Step 2: Call ExpressBank (Client Services)
BOK Financial handles death notifications through their main "ExpressBank" client services line. When you call, ask to be connected to the Deceased Accounts or Estate Processing unit.
- Phone: 844-517-3308
- Hours: Mon–Fri, 7:00 AM – 9:00 PM CT; Sat, 8:00 AM – 5:00 PM CT
Note: If you are calling for a specific regional brand (e.g., Bank of Oklahoma), you can also use their local customer service number, but they will likely route you to the same central operations team.
When you reach an agent, they will:
- Verify the decedent's identity
- Place a deceased flag on the account(s), which freezes automatic payments and online access
- Provide a case number or reference number
- Explain which documents are needed based on the specific account types (e.g., sole owner vs. joint)
- Confirm the mailing address for submitting documents
Step 3: Submit Required Documents
Mail the required documents (typically a certified death certificate and your ID) to the operations center.

Account Types
How BOK Financial Handles Different Account Types
Joint Accounts (JTWROS)
For accounts with "Rights of Survivorship," the surviving owner typically needs only a certified death certificate to remove the decedent's name. The account remains open and accessible to the survivor.
Timeline: 3–5 business days
POD (Payable on Death) / TOD (Transfer on Death) Beneficiary Accounts
Named beneficiaries can claim funds directly by providing a death certificate and ID. These assets bypass probate.
Timeline: 5–10 business days
Trust Accounts
Assets held in a Living Trust are managed by the Successor Trustee. BOK Financial will require a copy of the Trust Abstract or Certification of Trust to validate the new trustee's authority.
Timeline: 10–20 business days
Individual Accounts (Probate Required)
Accounts owned solely by the decedent with no beneficiary must go through probate. The Executor or Administrator must provide court-issued Letters Testamentary or Letters of Administration.
Timeline: 3–6+ months (dependent on court process)
Retirement Accounts (IRA)
Beneficiaries must file a claim. Spouses often have the option to roll over the IRA into their own, while non-spouses must take distributions according to IRS rules (typically within 10 years).
Timeline: 10–15 business days
Credit Cards and Loans
Outstanding balances on credit cards or personal loans are generally the responsibility of the estate. BOK Financial will file a claim against the estate for payment.
Timeline: Settled during estate administration
State Considerations
How Your State Affects the BOK Financial Process
BOK Financial operates under different brand names in different states (e.g., Bank of Oklahoma, Bank of Texas). While the bank's internal process is centralized, state probate laws dictate the requirements.
Key State Variations
| State | Brand Name | Small Estate Threshold | Notable Rules |
|---|---|---|---|
| Oklahoma | Bank of Oklahoma | $50,000 | Affidavit must be filed with the court in some cases |
| Texas | Bank of Texas | $75,000 | "Muniment of Title" is a unique, faster probate option |
| New Mexico | Bank of Albuquerque | $50,000 | Simplified probate for homes under $500k |
| Colorado | BOK Financial | $82,000 (adjusted annually) | Simple affidavit process for small estates |
| Arizona | Bank of Arizona | $75,000 (personal property) | 30-day waiting period for affidavit |

Timelines
How Long BOK Financial Takes to Release Funds
| Account Type | Estimated Timeline | Key Factor |
|---|---|---|
| Joint account | 3–5 business days | Quickest; just needs death cert |

| Trust account | 10–20 business days | Requires review of trust documents |
| Small estate affidavit | 2–4 weeks | Subject to legal review by the bank |
| Probate (simple) | 3–6 months | Waiting for court appointment |
| Probate (complex) | 6–12+ months | Delays often due to court/tax issues |
Note: Timelines start after all correct documents are received by the Operations Center in Tulsa.
Tips & Pitfalls
Common Pitfalls and Tips
Use the Correct Mailing Address
Sending documents to a local branch can cause delays. Mail directly to the Tulsa Operations Center (P.O. Box 2300) for faster processing.
Do Not Use the "Estate Settlement" Line for Notification
BOK Financial has a department that sells estate settlement services (acting as executor). Do not confuse this with the administrative department that handles deceased account closures. Call ExpressBank (844-517-3308) for account closures.
Stop Automatic Payments Immediately
Once you notify the bank, all auto-drafts (utilities, subscriptions) will be blocked. Ensure you make alternative arrangements to pay essential bills (like electricity or mortgage) to avoid service interruptions.
Check for Safe Deposit Boxes
Ask specifically if the decedent held a safe deposit box. Accessing these often requires specific court orders or a scheduled inventory session, depending on state law.
Keep the Case Number
When you first call, write down the Case Number or Service Request Number. You will need this for every follow-up call to track the status.
