What to do when a M1 account holder dies

Report the death to M1's Client Success at 1-312-600-2883

After an account holder at M1 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 M1's Client Success at 1-312-600-2883 with the proper legal authority documents.

Death claim process

Here is the step-by-step death claim process at M1:

Filing a claim

1
M1 is online-only, with no branches. Tell M1 Client Success through the in-app Messenger, its fastest channel. You do not need all the required documents before contacting M1.
2
Give M1 the email address associated with the deceased person's M1 account. That is how M1 locates the account.
3
Put the notice in writing. M1 Account Agreement Section 16 ("Event of Death") requires the representative of the estate or the surviving owner to give M1 written notice immediately.
4
Upload a certified copy of the death certificate and the court-issued documents showing authority over the estate. M1 states most accounts need nothing beyond these two and will contact you directly if more is required.

Required Documents

  • Death certificateAn official certified copy.
  • Written notice of the death, from the estate representative or surviving owner
  • Letters of Administration, Letters Testamentary, or a Court Letter of Appointment, not required when a transfer-on-death beneficiary is named or a joint owner survivesCourt-issued documents showing authority over the estate.
  • Government-issued photo ID for the claimantA driver's license, state ID or passport, uploaded at the document upload page.
  • Beneficiary Traditional IRA form or Beneficiary Roth IRA form, for an inherited IRA
  • Inheritance or estate tax waivers, where M1 requires them

What happens to each kind of account8

Payable-on-death account

With a transfer-on-death beneficiary named, the death certificate alone transfers the account into the beneficiary's name, with no court letters. M1 verifies the designation and provides next steps.1

Joint account with survivorship

On a joint brokerage account, ownership passes to the surviving owner with no additional steps, though M1 may ask to refresh documentation. The account statement shows whether an account is cleared by Apex or self-cleared by M1 Finance LLC.1

On an Apex-cleared joint account, Apex may freeze the account indefinitely if it cannot determine the proper distribution.2

Account in one name

With no transfer-on-death beneficiary and no surviving joint owner, the estate representative must supply the court-issued appointment documents.1

IRA

An IRA beneficiary opens an M1 Inherited IRA using the Beneficiary Traditional IRA form or Beneficiary Roth IRA form. M1 follows up on an Inherited IRA application by email within 2-3 business days.1

Investment account

An outstanding margin loan must be repaid on receipt of the death certificate. Because margin balances cannot be transferred, M1 automatically sells the most overweight Slices in the account to cover it.1

Crypto account

The crypto account is offered by Bakkt, in omnibus custodial wallets with no per-client private keys. It has no transfer-on-death or beneficiary designation, so the estate representative claims it, and the coins cannot be moved to an outside wallet through the M1 account.1

Custodial account (UTMA/UGMA)

Custodial accounts carry no beneficiary designation. M1 provides account details only to the custodian, so a successor custodian recognized under the governing state UTMA statute is the person M1 will deal with.1

Trust account

M1 Trust accounts carry no beneficiary designation.1

What M1's agreement and guidance say3

Telling the institution

Section 16 ("Event of Death") runs on written notice. M1 is not responsible for action taken on open orders before it has received notice of death and issued its own written acknowledgement, and the estate is liable for any net debit balance from transactions initiated before written notice arrived.3

What it does when notified

Section 16 lets M1 cancel all open orders and, at its discretion, close out any or all of the account without awaiting the appointment of a personal representative and without demand upon or notice to that representative.3

Section 29 separately authorizes M1 to sell assets, buy in short positions, and cancel open orders on the account holder's death.3

What it says about taxes

Section 16 lets M1 require inheritance and estate tax waivers, retain a portion of the account, or restrict transactions as it deems advisable to protect itself against tax, liability, penalty, or loss.3
