One of the key dangers with adding minority members such adult children is that it is difficult to remove them once they’re in the fund as there needs to be written consent in order for this to happen.

“Despite how well the deed may be written, this is one issue that we can never address in the deed and the constitution,” Mr Figot said.

In order for a member’s benefits to be rolled out from the fund, regulation 6.28(1) of the SISR states that a member’s benefits in a superannuation fund must not be rolled over from the fund unless the member has given to the trustee their consent to the rollover, explained Mr Figot.

SMSF trustees or “majority members”, the director said, may therefore want to ask any potential minority members to sign upfront contingent consent to be kicked out of the fund where there is an estrangement, before they actually become members in the fund.

The deed should also expressly allow for the member to be removed from the fund on the condition that they have signed this contingency consent, the director added.

“I’ve worked on quite a few family estrangement matters over the years and it certainly does happen,” Mr Figot said.

“This is going to be very relevant in the future if the imputation credit laws change.”
