What happens to BOK Financial accounts after the account holder dies depends on how each account was titled. Beneficiary-designated and trust-owned accounts transfer directly. Accounts in the deceased's name alone go through the estate, and the executor or administrator works with BOK Financial's BOK Financial Fiduciary Services / Private Wealth (1-844-517-3308) to claim the funds.
BOK Financial offers an online claims portal that makes the initial filing process more straightforward. Survivors can also initiate claims by phone or by mailing documentation directly.
Deposit, investment & retirement accounts
To file a claim after an account holder's death, here is what BOK Financial requires:
Filing a claim
1
Contact BOK Financial ExpressBank at 1-844-517-3308 (Mon-Fri 7am-9pm CT, Sat 8am-5pm CT) or visit a branch of the relevant consumer brand (Bank of Oklahoma, Bank of Texas, Bank of Albuquerque, or BOK Financial) to report the death -- all four brands share the same ExpressBank service line and deceased-account operations
2
Provide a certified death certificate; the deposit account agreement governs how the balance is released and the bank places a hold on the account pending documentation
3
Choose the appropriate settlement path based on account type:
- For POD accounts: beneficiaries provide government-issued ID and death certificate to claim funds directly, bypassing probate
- For joint accounts with right of survivorship: surviving owner provides death certificate to remove the deceased
- For trust accounts: successor trustee provides trust documentation and government-issued ID
- For small estates with no POD/joint/trust designation: an eligible heir may collect deposit balances by small-estate affidavit under state law (Oklahoma banks may release balances under $50,000 by affidavit per Title 6 O.S. Section 906 / 58 O.S. Section 393; Texas and New Mexico each allow a small-estate affidavit to collect deposits below their state-set threshold)
- For larger probate estates: provide Letters Testamentary or Letters of Administration from probate court
- For full estate administration: BOK Financial's wealth/trust arm (BOKF, NA fiduciary operations) can serve as executor, co-executor, trustee, or agent and provide probate representation (regional Fiduciary Services -- Oklahoma/Arkansas 918-293-7583, Arizona 480-596-4322, Colorado 303-864-7260, Kansas/Missouri 913-307-1842)
4
Assets distributed per beneficiary designation, trust terms, small-estate affidavit, or probate court order
Required Documents
- Certified death certificate
- Government-issued ID for claimant/beneficiary
- Account number(s) of the deceased (if known)
- Trust documents (if trust-owned account)
- Letters Testamentary or Letters of Administration (if estate/probate required)
- Small Estate Affidavit (if eligible under state law)
What to know at this institution
BOK Financial Corporation runs consumer banking under four brands -- Bank of Oklahoma, Bank of Texas, Bank of Albuquerque, and BOK Financial (used in AR/AZ/CO/KS/MO) -- that share one ExpressBank service line (1-844-517-3308) and a single deceased-account/estate operation, so heirs use the same process regardless of which brand name is on the account. Release of a deposit balance is governed by the deposit account agreement: the bank holds the account on notice of death and pays out per the POD designation, survivorship, trust terms, small-estate affidavit, or probate authority. Oklahoma-headquartered accounts benefit from the Oklahoma Banking Code (Title 6 O.S. Section 906), under which a bank may release balances under $50,000 by affidavit at least 10 days after death; Texas and New Mexico offer parallel small-estate affidavit collection at their own state-set thresholds. BOK Financial's wealth/trust arm (BOKF, NA fiduciary operations) can also act as executor, co-executor, trustee, or agent and handle full estate administration -- asset valuation, expense payments, investment management, tax coordination, and distribution, including specialty assets such as real estate, oil and mineral rights, and farmland. For Fiduciary Services, contact the regional office: Oklahoma/Arkansas 918-293-7583, Arizona 480-596-4322, Colorado 303-864-7260, Kansas/Missouri 913-307-1842.
Mortgage and home lending
Mortgages and home equity loans are liabilities, not assets. They do not have beneficiaries and cannot be retitled to a trust. When a borrower dies, the loan obligation transfers with the property to whoever inherits it. Under the federal Garn-St. Germain Act, the lender cannot accelerate the loan or call it due when the property transfers to a surviving spouse, child, or the borrower’s revocable trust.
1
Notify BOK Financial of the borrower's death by calling Mortgage Servicing at 1-866-910-5224
2
Gather and submit required documentation:
- Certified copy of the death certificate
- Deceased borrower's full legal name, Social Security number, and loan number
- Documentation proving your ownership interest: probated will, court order, recorded deed, or trust document naming you as successor trustee or beneficiary
3
Request information about the Successor in Interest process to establish your legal interest in the property
4
BOK Financial will review your documentation and confirm your status as a Successor in Interest
5
Once confirmed, discuss options:
- Continue making payments
- Apply for loan assumption
- Refinance
- Pay off the balance
6
Continue making monthly mortgage payments during the review process to avoid default
Required Documents
- Certified copy of the death certificate
- Government-issued photo ID for the heir or personal representative
- Documentation proving ownership interest in the property (probated will, court order, recorded deed, or trust document)
- Letters Testamentary or Letters of Administration (if going through probate)
- Marriage certificate (if surviving spouse)
What to know at this institution
Under the federal Garn-St. Germain Depository Institutions Act (12 U.S.C. 1701j-3), BOK Financial cannot enforce a due-on-sale clause when the property transfers to a surviving spouse, child, relative upon death, or the borrower's revocable living trust. Confirmed Successors in Interest are entitled to account information and loss mitigation options under CFPB mortgage servicing rules. Mortgage Servicing phone: 1-866-910-5224 (Mon-Fri 7am-6pm CT). Fax: 918-619-8948. Mail: BOK Financial, Attn: Customer Care Department, 7060 S. Yale Avenue, Suite 200, Tulsa, OK 74136-5721.

How to open an estate account at BOK Financial →Expected timelines at BOK Financial: POD and joint accounts may be processed within days of receiving documentation; estate accounts vary based on probate complexity.

All death certificates and court documents must be certified copies.
Frequently asked questions
A POD designation lets you name beneficiaries on your deposit accounts (checking, savings, money market, and CDs). At death, the account balance transfers directly to your named beneficiaries without going through probate. POD designations override your will. To set up or update a POD designation, visit a branch or call ExpressBank at 1-844-517-3308.
Under the federal Garn-St. Germain Act (12 U.S.C. 1701j-3), BOK Financial cannot accelerate the loan when the property transfers to a surviving spouse, child, or the borrower's revocable trust.
