Brand change
BMO Harris Bank N.A. rebranded to BMO Bank N.A., with the U.S. legal-entity name change effective September 3, 2023 (the simplified "BMO" branding was announced in September 2022), retiring the 140-year-old "Harris" name. Same legal entity, same account numbers, debit cards, online logins, and customer service numbers -- a brand update, not a merger. The rebrand followed BMO's February 1, 2023 acquisition of Bank of the West. Effective September 2023.
The procedures below reflect BMO's accounts. Account servicing may transfer as the change takes effect.

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.

- Call the mortgage line at 1-844-219-6003 or general customer service at 1-888-340-2265
- Provide the deceased borrower's full legal name, Social Security number, and loan number
- Submit a certified copy of the death certificate
2
Request information about the Successor in Interest process to establish your legal interest in the property
3
Provide documentation proving your ownership interest: probated will, court order, recorded deed, or trust document naming you as successor trustee or beneficiary
4
BMO will review your documentation and confirm your status as a Successor in Interest
5
Once confirmed as Successor in Interest, choose from available options:
- Continue making payments on the existing loan
- Apply for loan assumption
- Refinance the mortgage
- Pay off the remaining 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

What to know at this institution
Under the federal Garn-St. Germain Depository Institutions Act (12 U.S.C. 1701j-3), BMO 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. General customer service: 1-888-340-2265. BMO Wealth Management: 1-800-472-0060.
Prepare your letter of instruction to BMO
BMO provides its own letter-of-instruction form. Answer a few questions and we complete that official form for you to print and sign.
Build your letter of instructionHow long the process takes at BMO: POD/TOD accounts: 2-4 weeks after documentation received. Estate accounts: varies by complexity. The most common reason for delays is missing or incomplete documentation, so submitting everything upfront is the best way to keep things moving.
BMO requires several documents to process a claim, including Certified death certificate (multiple copies recommended), Government-issued ID for beneficiary, executor, or trustee, and Social security number for each beneficiary, and additional documentation depending on the account type. Certified copies are typically needed—photocopies are generally not accepted for death certificates or court documents.
Frequently asked questions
BMO Alto has its own decedent process separate from branch accounts. Call BMO Alto at 1-855-266-8100 (available 24/7) or download the Decedent Account Letter of Direction from [alto.bmo.com/en-us/legal/](https://www.alto.bmo.com/en-us/legal/). The form can be submitted by joint owners, POD beneficiaries, executors, estate administrators, or small estate beneficiaries. New Jersey residents must also submit NJ Form L-8 or L-4 state inheritance tax waiver. Request the Date of Death Value Letter using the separate form linked on the same page if you need it for estate tax filings. Alto checks are made payable to the estate or to the small estate beneficiary listed on the form.
On BMO marital deposit accounts with a POD designation, upon the death of either owner 50% of the account passes to the surviving owner and 50% passes to the POD beneficiaries. Any account owner may change beneficiaries at any time without the consent of other owners or beneficiaries. With multiple POD beneficiaries, each surviving beneficiary receives an equal share unless otherwise specified, and BMO issues a separate check to each. If no named beneficiary survives the last account owner, the balance is paid to the estate of the last surviving owner. BMO requires original signed POD/TOD forms -- fax or photocopy is not accepted.
Call the BMO mortgage line at 1-844-219-6003 (or 1-888-340-2265 for HELOCs) with a certified death certificate and documentation of your ownership interest in the property. BMO processes this through its Successor in Interest workflow, which is required under CFPB mortgage servicing rules. Under the federal Garn-St. Germain Act (12 U.S.C. 1701j-3), BMO cannot enforce the due-on-sale clause when the property transfers to a surviving spouse, a relative who inherits, or the borrower's revocable living trust. Once you are confirmed as a Successor in Interest, you can continue the existing payments, apply for loan assumption, refinance, or pay off the balance. For HELOCs, the draw period ends at the borrower's death even though confirmed successors are not required to pay the full balance immediately.
BMO's Death Claims can be reached by phone at 1-888-340-2265 and fax at 1-844-739-1152 for questions throughout the claims process.
Multiple BMO accounts may mean multiple claims. Some account types can be processed together, but others require their own documentation. Check with the BMO Wealth Management - Trusts & Estates to confirm what applies.
