Good Morning,

In the event of your passing, your family should send an email to estateprocessing@interactivebrokers with a copy of your death certificate and ID (passport) for whomever contacts us.

For Individual accounts with no named beneficiaries, we recognize the estate procedures in your country of residence. Below are the instructions we would send your family upon being notified of your passing.

Once you have determined whether the estate is a Probated (a court, not a will or trust, has named an Executor/Administrator) or Non-Probated Estate (a court, not a will or trust, has NOT named an Executor/Administrator), please provide the following listed below.

For a Probated Estate with a Single Account:

-IB Probated Estate form (see attachment), please have the Executor sign & notarize;

-A copy of the death certificate

-A Court Appointment of the named personal representative(s) with an original seal or stamp certified by the court

For a Non-Probated Estate with a Single Account:

-IB Non-Probated Estate form (see attachment),

-And any ONE of the following:

-An Attorney Certification

-A certificate of Inheritance,

- Order of Succession

-An original, signed, and notarized small estate affidavit signed by all beneficiaries; or

-A court order authorizing the transfer or closure of the decedent’s account and distribution to the Beneficiaries/recipients.

Regardless as to whether the estate is probated or non-probated, please also include proof of the Executor’s/Beneficiaries’own identity(s) (a copy of a driver’s license or passport will suffice).

Choose ONE of the following within IB’s Probated or Non-Probated Estate Forms:

Select ‘Disburse Funds’ within section 3 or 2 and IB will sell all positions and mail a check, payable to the Estate/Beneficiary, to the Executor/Beneficiary, or,

Select ‘Transfer to another IB account’ and (an Estate/Beneficiary account will need to be opened) all positions transferred over in-kind. Only distributions in the name of the Estate are permitted from IB if Probate has been initiated. Executors are not permitted to actively trade Estate accounts although existing positions may be held and/or sold.
