Yes, you may dispute a decision made by a superfund.
Whilst individual fund processes may vary, generally a fund will give you 28 days’ notice of their decision to award superannuation proceeds to a particular person/s. You may, within that time, contact the fund to object and to outline reasons for your objection. After the complaint is received the fund may either conduct a dispute resolution process to see whether a compromise may be reached with the other interested party/ies, or alternatively, may make a new decision based on your complaint and any further information provided from other parties.
Should you remain unsatisfied with the fund’s final determination, you will typically have 28 days to dispute the decision with the Australian Financial Complaints Authority (AFCA), who may review the matter anew to reach its own determination.
Finally, should you be left unsatisfied by an AFCA decision you may appeal it at the Federal Court of Australia.
