How do I manage the estate of a deceased CommSec customer who held an account in a company name?
These accounts are treated differently. In the event that a director of a company with a CommSec account in its name passes, you will firstly need to contact ASIC to update their company information. Please then let us know, via email or by phoning us using the contact details below. We will request a certified copy1 of the Death certificate2.
To add a director, please complete an Addtitional Authority form and send this to us with a certified copy1 of the new director’s identification (passport or driver’s license).
Please email the documentation to commsecestatesmanagement@cba.com.au or post to CommSec estates management, Locked bag 22, Australia Square, NSW 1215.
We’re here to help
If you have any questions, please contact us on 13 15 19 or +61 2 9115 1417 if calling from outside Australia, 8am to 7pm (Sydney time). Alternatively, you can email commsecestatesmanagement@cba.com.au
