After a IBC Bank account holder dies, accounts with beneficiary designations or trust ownership transfer to the designated recipients without probate. Solely-owned accounts require the estate's representative to contact IBC Bank's IBC Investment Services (Estate Planning) at (210) 841-3000 with the proper legal authority documents.
IBC Bank 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.
Death claim process
Follow these steps to file a death claim with IBC Bank:
Filing a claim
1
Notify the account's home branch of the death. IBC has no central estate or survivor unit and no claims portal — find the branch at https://www.ibc.com/locations or use the branch numbers at https://www.ibc.com/contact-us (IBC Laredo (956) 722-7611, IBC San Antonio (210) 518-2500, IBC Houston (713) 526-1211, IBC Corpus Christi (361) 888-4000, IBC McAllen (956) 686-0263, IBC Brownsville (956) 547-1000, IBC Austin (512) 397-4506, IBC Oklahoma (405) 841-2100)
2
Provide a certified copy of the death certificate and your government-issued photo ID
3
Claim process depends on how the account is titled:
- POD beneficiary: present the death certificate and valid ID to claim funds directly at the branch
- Trust account: successor trustee presents the trust agreement (or Certification of Trust) and the death certificate to gain access
- No beneficiary or trust: probate may be required -- present Letters Testamentary or Letters of Administration from the court
- Small estate (Texas): a Small Estate Affidavit may be accepted in lieu of full probate if the estate qualifies under Texas Estates Code Section 205.001
- Small estate (Oklahoma): an affidavit procedure may be available for qualifying estates under Oklahoma law
4
Send written notice of the death to IBC's legal-notice address as well as telling the branch. IBC's Deposit Account Agreement (https://assets.milestoneinternet.com/ibc-bank/pdf/deposit-account-agreement.pdf) says IBC "may continue to recognize the authority of the agent (attorney in fact) named in the Power of Attorney until such time as it has actual knowledge of the termination of the agent's authority" -- death terminates that authority -- and that "actual knowledge ... does not exist until the bank has had a reasonable time after receipt and acknowledgment of such notice of revocation to act upon it." The agreement names the address: Dennis E. Nixon, President, International Bancshares Corporation, P.O. Drawer 1359, Laredo, TX 78042-1359
5
If checks or automatic debits are still outstanding, raise them with the branch immediately. IBC's Deposit Account Agreement contains no "death or incapacity" clause and sets no fixed number of days for which it will keep honoring a decedent's items, so there is no published grace period to rely on
6
Complete the claim or distribution paperwork the branch provides. IBC publishes no downloadable death claim form; the branch supplies its own paperwork
7
Funds are released after the branch reviews and approves the documents
Required Documents
- Certified copy of the death certificate
- Government-issued photo ID for the claimant
- Letters Testamentary or Letters of Administration (if probate required)
- Trust agreement or Certification of Trust (if account held in trust)
- Small Estate Affidavit (if applicable under Texas Estates Code Section 205.001 or Oklahoma law)
- Proof of relationship to the deceased
- Claim or distribution paperwork (supplied by the IBC branch — not published for download)
What to know at this institution
IBC handles every death claim at the branch: there is no estate services department, no claims portal, and no downloadable death claim form on ibc.com. Two IBC-specific facts drive the process. (1) The Deposit Account Agreement has no "death or incapacity" clause -- IBC does not commit to any post-death window for honoring a decedent's checks, unlike banks that publish a 10-day rule -- so outstanding items must be raised with the branch immediately. (2) The agreement's Powers of Attorney clause routes written revocation/termination notice (death terminates the agency) to Dennis E. Nixon, President, International Bancshares Corporation, P.O. Drawer 1359, Laredo, TX 78042-1359, and states that IBC's "actual knowledge" of the termination does not exist until it has had a reasonable time after receiving and acknowledging that notice to act on it. Also note the agreement's joint-account clause: a pledge of joint-account funds as collateral by any Authorized Signatory "shall remain valid and enforceable after the death of the Authorized Signatory executing such pledge." Unclaimed accounts fall under the agreement's Dormant/Inactive and Abandoned Account clause (a $5.00 per month inactivity fee applies, and abandoned balances are remitted to the state).

Checks made out to the estate deposit into an account titled to the estate, opened by the appointed executor or administrator under the estate's EIN.
How to open an estate account at IBC Bank →Processing timelines at IBC Bank: Varies by account type, document completeness, and whether probate is required. Accounts with named POD beneficiaries process faster than probate estates. IBC publishes no service-level timeline for estate claims. Incomplete documentation is the most common cause of delays—submitting all required documents with the initial claim helps avoid additional processing time.
Documentation required by IBC Bank includes Certified copy of the death certificate, Government-issued photo ID for the claimant, and Letters Testamentary or Letters of Administration (if probate required), along with additional paperwork that varies by account type. All death certificates and court documents must be certified copies.
Frequently asked questions
IBC makes no such commitment. Its Deposit Account Agreement (https://assets.milestoneinternet.com/ibc-bank/pdf/deposit-account-agreement.pdf) has no "death or incapacity" clause, so unlike banks that publish a ten-day post-death window for paying checks drawn before the date of death, IBC states no window at all. What the agreement does address is agent authority: IBC "may continue to recognize the authority of the agent (attorney in fact) named in the Power of Attorney until such time as it has actual knowledge of the termination of the agent's authority," and actual knowledge "does not exist until the bank has had a reasonable time after receipt and acknowledgment of such notice of revocation to act upon it." Death terminates a power of attorney, so an executor should tell the branch immediately and also send written notice to the address the agreement names: Dennis E. Nixon, President, International Bancshares Corporation, P.O. Drawer 1359, Laredo, TX 78042-1359.
No. IBC's Deposit Account Agreement states that funds in a joint account may be pledged by any Authorized Signatory as collateral for that signatory's debt to the bank, and that "such pledge shall remain valid and enforceable after the death of the Authorized Signatory executing such pledge." A surviving joint owner or a POD beneficiary can therefore find the balance encumbered by a debt the decedent pledged it against. The agreement carves out one exception to IBC's setoff and security interest: they do not apply to collateral for a homestead equity loan. Ask the branch whether any pledge or setoff is recorded against the account before you assume the balance is free to distribute.
The account's home branch. IBC has no estate services department, no death claim portal, and no downloadable estate forms — the whole process, including the claim paperwork itself, is run out of the branch that holds the account. Branch phone numbers and mailing addresses are published at https://www.ibc.com/contact-us (IBC Laredo (956) 722-7611, IBC San Antonio (210) 518-2500, IBC Houston (713) 526-1211, IBC Corpus Christi (361) 888-4000, IBC McAllen (956) 686-0263, IBC Brownsville (956) 547-1000, IBC Austin (512) 397-4506, IBC Oklahoma City (405) 841-2100), and branches are mapped at https://www.ibc.com/locations. IBC Online Banking Support at (210) 841-3000 (Mon-Fri 8:30AM-5:30PM CT; Sat 8:30AM-1:00PM CT) can disable online and mobile access on the account but cannot process the claim. Because IBC operates only in Texas and Oklahoma, the alternative to probate is the Texas small estate affidavit under Texas Estates Code Section 205.001 or Oklahoma's affidavit procedure — the branch decides whether to accept it.
It goes dormant and then escheats. Under the agreement's Dormant/Inactive and Abandoned Account clause, IBC may classify an account as dormant without notifying anyone, a $5.00 monthly inactivity fee applies, and the balance is ultimately turned over to the appropriate state agency once it is considered abandoned. The agreement also warns that a deposit into a dormant account does not necessarily reactivate it — IBC has to be contacted to reclassify it as active, and items may be returned in the meantime. If you find an IBC account in a decedent's papers, contact the branch rather than assuming a deposit or transfer will keep it alive.
Yes. Under the federal Garn-St. Germain Depository Institutions Act, a lender cannot accelerate the loan solely because you transfer your primary residence into a revocable living trust in which you remain a beneficiary and occupant, and the same protection covers a transfer to a spouse or child at death. IBC's Deposit Account Agreement separately confirms that its right of setoff and security interest "are not applicable to our collateral for any homestead equity loan," which is relevant in Texas where home equity lending is constitutionally restricted. Notify the branch of the transfer, and have an attorney review the due-on-sale language in your specific note and deed of trust before recording anything.
IBC Bank's Estate/death claims are handled at the account's home branch (no central estate unit) can be reached by phone at (210) 841-3000 for questions throughout the claims process.
Multiple IBC Bank accounts may mean multiple claims. Some account types can be processed together, but others require their own documentation. Check with the IBC Investment Services (Estate Planning) to confirm what applies.
