Probate or Letters of Administration may be required by a super fund in circumstances where the member left no valid binding beneficiary nomination. In such cases, the fund may require you to produce the Supreme Court Grant of Probate or Letters of Administration before releasing the super funds to the appointed legal personal representative.
It is best to speak directly with the super fund to determine whether or not probate will be required to release the fund balance and any insurance payable. Superannuation funds will often require you to fill out certain paperwork in order to reach a determination regarding the payout.
