What happens to Mercury 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 Mercury's Mercury Personal Support (no dedicated estate or bereavement department; deceased joint-owner removals, trust-account changes, and closures are handled here) ((415) 878-1068) to claim the funds.
Mercury 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
Here is the step-by-step death claim process at Mercury:
Filing a claim
- Any surviving joint account holder emails personal@mercury.com to request the deceased holder's removal. Mercury states this is the only way an account holder can be removed on death
- A joint account CANNOT be converted to an individual account. If only one owner is left, that survivor has to close the joint account and open a new individual Mercury Personal account to keep banking with Mercury
- Joint owners are joint tenants with right of survivorship, so the funds pass to the survivor(s) and the POD beneficiaries take only on the death of the LAST owner
- On proof of death of the last surviving owner, the bank pays the checking and savings balances to the surviving designated beneficiaries, evenly split, outside probate
- Provide a certified copy of the death certificate and government-issued photo ID for each beneficiary
- If the beneficiary is a trust, provide the trust's legal name, its Tax Identification Number, and trustee identification
- If no designated beneficiary is living, the funds are paid to the legal representative of the last surviving account owner
- The successor trustee (or anyone with knowledge of the death) must notify Mercury promptly and deliver, WITHIN 30 CALENDAR DAYS of the death, a certified copy of the grantor's death certificate plus documentation of the successor trustee's authority
- That documentation may include an updated Certificate of Trust, authenticated excerpts of the trust instrument, a trustee affidavit, a court appointment document, or Letters Testamentary or of Administration
- Notice alone does not get the successor trustee access: Mercury may disable transfers, cards, and distributions while it reviews
- If the trust becomes irrevocable on death, expect friction — irrevocable trusts sit outside Mercury's standard trust account offering, and the bank may re-title the account (to an estate or irrevocable trust account), demand an EIN, limit features, or close it and remit the funds under the trust's terms
- Provide a certified copy of the death certificate and your government-issued photo ID
- Provide the entity's formation documents: operating agreement, articles of incorporation, or partnership agreement
- Single-owner entity: provide Letters Testamentary or Letters of Administration, since the ownership interest passes through the deceased owner's estate
- Multi-owner entity: provide the corporate resolution or successor documentation showing who now has authority
- A Mercury Treasury balance is not a deposit — it sits in the business's name at Apex Clearing Corporation and is claimed through the entity and Apex's transfer process
Required Documents
- Certified copy of the death certificate
- Government-issued photo ID for the claimant or for each beneficiary
- Mercury Personal with a POD beneficiary: death certificate and beneficiary ID — no probate documents needed
- Trust beneficiary of a Personal account: trust legal name, Tax Identification Number, and trustee identification
- Mercury trust account: certified death certificate of the grantor plus proof of successor trustee authority (updated Certificate of Trust, authenticated trust excerpts, trustee affidavit, court appointment, or Letters), delivered within 30 calendar days of the death
- Business accounts: operating agreement, articles of incorporation, or partnership agreement
- Business accounts, single owner: Letters Testamentary or Letters of Administration
- Business accounts, multiple owners: corporate resolution or successor documentation
- Trust account converting to irrevocable: an EIN and updated tax information, if Mercury requires it
What to know at this institution
Mercury does not publish a deceased-account page, a claim form, or a claims mailing address, and it is online-only — there is no branch to walk into. Everything runs through email and the app, with a phone number published in the Column N.A. consumer deposit agreement at (415) 878-1068. Four Mercury-specific points do the real work here. First, the account you are claiming is not held by Mercury: Choice Financial Group and Column N.A. hold the deposits, Patriot Bank N.A. issues the IO card, and Apex Clearing Corporation custodies Treasury and Invest, so the governing terms are the partner bank's, not Mercury's. Second, the Column agreement gives the bank a right of SETOFF that survives death — if the account holder owed a debt at death, the bank is authorized to apply funds credited to the account after death against it, and it can follow the proceeds into any other account held there. Third, government benefit payments deposited after death can be clawed back: Social Security and Railroad Retirement electronic payments are subject to reclamation, and the bank reserves the right to charge the account for the full amount, so an executor should stop those deposits rather than spend them. Fourth, on a business account there is no POD or TOD to invoke at all — the deposits follow the entity, and if the entity had a single owner they follow that owner's estate through probate. The Column agreement also makes the estate responsible for reimbursing the bank if it releases funds after death and is then hit with a tax or reclamation claim.
Opening an account for the estate itself
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.
Does Mercury offer estate accounts? →How long the process takes at Mercury: Mercury publishes no processing time. A Mercury Personal POD claim moves fastest because it avoids probate entirely; a trust account has a documented 30-calendar-day window for the successor trustee to deliver the death certificate and proof of authority; a business account claim is gated by how long it takes to produce entity documents and, for a single-owner entity, court-issued Letters. Email personal@mercury.com (Personal) or help@mercury.com (business) for a case-specific estimate. The most common reason for delays is missing or incomplete documentation, so submitting everything upfront is the best way to keep things moving.
Mercury requires several documents to process a claim, including Certified copy of the death certificate, Government-issued photo ID for the claimant or for each beneficiary, and Mercury Personal with a POD beneficiary: death certificate and beneficiary ID — no probate documents needed, 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
Mercury business accounts — checking, savings, Vault, and Treasury — carry no POD or TOD beneficiary designation and cannot be trust-titled, so none of them pass outside probate on their own. The account follows the business entity. If the deceased was the only owner of a single-member LLC or similar entity, the ownership interest passes through the deceased owner's estate, and Mercury will want a certified death certificate, the entity's formation documents, and court-issued Letters Testamentary or Letters of Administration before it moves account control. If the entity has multiple owners, succession follows the operating agreement, bylaws, or partnership agreement, evidenced by a corporate resolution or successor documentation. Mercury Treasury is a further step removed: it is a brokerage account held in the business's name at Apex Clearing Corporation, not a bank deposit, and is claimed through Apex's transfer process. Because nothing at the account level can be designated, the entity's formation documents are what actually decide who controls a Mercury business account after a founder dies.
Yes on Mercury Personal, and yes to a trust. Mercury Personal checking and savings support up to 5 individual POD beneficiaries OR 1 trust, added in the dashboard under Settings, then Account Settings, then Beneficiaries. An individual needs a full name, date of birth, and home address, with SSN optional for identity verification; a trust needs its legal name and Tax Identification Number. Two limits are worth planning around: balances are split EVENLY among the named beneficiaries, so a POD designation cannot mirror an uneven bequest, and there are no contingent beneficiaries. Per the Column N.A. agreement, beneficiaries take only on the death of the LAST surviving owner, and if no named beneficiary is living the funds go to the legal representative of that last owner. On a Mercury TRUST account the rules tighten: up to 5 beneficiaries, but they must be named in the original application and cannot be changed self-serve afterward — any change goes through personal@mercury.com. Business accounts have no POD or TOD option at all.
Email personal@mercury.com. Mercury states that in the case of a joint account holder's death, any joint account holder can contact personal@mercury.com to request the deceased holder's removal, and that this is the only route — a joint owner cannot otherwise remove a fellow owner. Joint owners are treated as joint tenants with right of survivorship, so the funds belong to the survivor, and any POD beneficiaries take only after the LAST owner dies. But the account may not survive with them: Mercury does not support converting a joint account into an individual account, so if a two-owner joint account is left with a single owner, that survivor has to close it and open a new individual Mercury Personal account. A joint account with three or more owners keeps running as long as two owners remain. Send the notice promptly — until Mercury has notice of the death it may keep processing transactions, and an authorized user's access, though it terminates by law at an owner's death, may keep being honored until Mercury has written notice and a reasonable opportunity to act on it.
The partner bank's. Mercury is a fintech, not a bank: the deposits sit at Choice Financial Group and Column N.A., the IO card is issued by Patriot Bank, N.A., and Treasury and Invest are custodied at Apex Clearing Corporation. Mercury support is the first point of contact, but the legal terms come from the Column N.A. Consumer Deposit Account Agreement (the POD payout, the death and incapacity clause, and the trust account rules) and its commercial counterpart. Three of those terms cost survivors money if they are missed. The bank may place a hold on the account once it is notified of a death and refuse all transactions until it verifies the successor. The bank's right of SETOFF survives the account holder's death: if the holder owed it a debt, it is authorized to apply funds credited to the account after death against that debt, and it can follow the proceeds into any other account held there. And government benefit payments deposited after death are subject to reclamation — Social Security and Railroad Retirement payments in particular — with the bank reserving the right to charge the account for the full amount, and the estate on the hook to reimburse the bank if it releases funds and is later hit with a tax or reclamation claim. Stopping those deposits is the first thing to do, not the last.
