When a M&T Bank account holder 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 M&T Bank's Estate Administration Services / Wilmington Trust (1-800-724-2440) to access and distribute the funds.
M&T Bank provides an online portal for initiating death claims, which can simplify the initial notification and document submission process. Claims can also be started by phone or by mailing the required documents.
Here is the step-by-step death claim process at M&T Bank:
Court and probate documents vary by state and estate size. Legal Document Processing (for overnight/in-person delivery): 626 Commerce Drive, Amherst, NY 14228. Legal Document Processing (USPS): P.O. Box 844, Buffalo, NY 14240-0844.
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.
Under the federal Garn-St. Germain Depository Institutions Act (12 U.S.C. 1701j-3), M&T Bank 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 treated as borrowers under CFPB mortgage servicing rules and are entitled to account information, loss mitigation options, and assumption rights. Legal Document Processing (overnight/in-person): 626 Commerce Drive, Amherst, NY 14228. Legal Document Processing (USPS): P.O. Box 844, Buffalo, NY 14240-0844. Estate Services email: EstateServices@mtb.com.
Processing timelines at M&T Bank: Varies based on account type, documentation, and state probate requirements. Incomplete documentation is the most common cause of delays—submitting all required documents with the initial claim helps avoid additional processing time.
M&T Bank requires several documents to process a claim, including Legible copy of death certificate with visible seal (obituary or newspaper notice may serve as initial proof), Government-issued ID for beneficiary or estate representative, and Letters Testamentary or Letters of Administration (if no POD designation), and additional documentation depending on the account type. Certified copies are typically needed—photocopies are generally not accepted for death certificates or court documents.
Visit an M&T Bank branch or call 1-800-724-2440 to request a Payable on Death (POD) designation form. You can name primary and contingent beneficiaries, including trusts. POD designations are available on checking, savings, money market, and CD accounts. You will need each beneficiary's full legal name, date of birth, and relationship.
Call M&T customer service at 1-800-724-2440, visit a local branch, or email EstateServices@mtb.com. You can also fax documents to 716-274-1087 or mail them to M&T Bank Estate Services, PO Box 1850, Buffalo, NY 14240. Provide the deceased's full name, date of birth, and Social Security number along with a legible copy of the death certificate with a visible seal.
Upon receipt of a valid death certificate, M&T will change the account name to "Estate of..." and restrict account activity. For accounts with POD beneficiaries, assets transfer directly to those beneficiaries without probate. For joint accounts with right of survivorship, the surviving owner retains access. For individual accounts without POD, the executor must present probate documents such as Letters Testamentary or Letters of Administration.
Yes. Payable on Death (POD) beneficiary designations on M&T Bank accounts take precedence over instructions in your will. Assets with POD designations transfer directly to the named beneficiaries upon proof of death, bypassing probate entirely. Keep your beneficiary designations updated whenever your circumstances change.
For POD accounts, the named beneficiary needs a government-issued photo ID and a copy of the death certificate. For accounts without POD, the estate representative needs a death certificate, government-issued ID, and court-issued Letters Testamentary or Letters of Administration. Small Estate Affidavits may be accepted where state law allows. If a trust is the beneficiary, trust documents are also required.
M&T Bank's Estate Administration Services / Wilmington Trust can be reached by phone at 1-800-724-2440, email at EstateServices@mtb.com, and fax at (716) 274-1087 for questions throughout the claims process.
If the deceased held multiple M&T Bank accounts, each may require a separate claim or have different documentation requirements. The Estate Administration Services / Wilmington Trust can confirm which accounts require individual attention and which can be processed together.
