The Fund Keeps Running and the Trusteeship Changes Immediately
When an SMSF member dies, three things happen at once. The fund's trustee structure changes and must be made compliant within a limited period. The deceased's benefit must be cashed as soon as practicable, as a lump sum or a death benefit income stream. And the surviving trustee is administering a fund while dealing with a death, which is the practical difficulty.
- The answer: The legal personal representative can act as trustee during the administration period, and the benefit is paid according to a valid binding nomination or the trustee's discretion.
- The trap: A two-member individual-trustee fund cannot have one individual trustee, so the structure has to change — usually to a corporate trustee or by adding a second individual.
- The recommendation: Use a corporate trustee from the start. A sole-director company continues without any structural change on the death of a member.
Where the AI summary above gets this wrong
"When an SMSF member dies the fund is wound up."
That's surface-true. Here's what it misses:
- The fund continues — The deceased's benefit must be cashed, but the fund itself continues with the surviving member. Winding up is a choice rather than a consequence.
- The trustee structure is the immediate problem — A two-member fund with individual trustees cannot operate with one individual trustee, so the structure has to be fixed within a limited period.
01 The trustee question
An SMSF with individual trustees needs at least two. On the death of one member of a two-member fund, the survivor cannot be the sole individual trustee, so the fund has to appoint another trustee or convert to a corporate trustee.
The legal personal representative of the deceased can act as a trustee in their place during the estate administration period, which provides breathing room but is not a permanent answer.
A corporate trustee avoids the problem entirely: a company with a sole director is permitted, so the structure continues unchanged. That is the strongest practical argument for a corporate trustee and it only helps if it was set up beforehand.

02 Cashing the benefit
The deceased's benefit must be cashed as soon as practicable after death, as a lump sum or as a death benefit income stream to an eligible dependant. It cannot simply remain in the fund as the deceased's interest.
Where it is paid as an income stream to a surviving spouse, the survivor's own transfer balance cap governs how much can continue — the mechanics are in the pension or lump sum post.
A valid binding death benefit nomination directs the payment. Without one, the surviving trustee decides — and in an SMSF that trustee is frequently a person with an interest in the outcome, which is where disputes arise.
Shows: how a deceased member's SMSF benefit splits between a continuing income stream to a spouse and an amount that must leave the retirement phase. Ignores: the trustee structure change, liquidity in the fund, the tax on any amount paid to a non-dependant, and the twelve month reversionary window.
03 The practical difficulty
The surviving member is administering a fund, arranging a valuation, obtaining an audit and making a benefit decision while dealing with a death. That is a real burden and it arrives immediately.
Illiquid assets make it worse. A fund holding a property may not be able to cash the benefit without selling, and the wind-up timetable is set by the asset rather than by anyone's convenience — the point made in the wind-up post.
For many households the right answer after a death is to roll the survivor's benefit into a large fund and close the SMSF, and planning that transition in advance is considerably easier than improvising it.
A corporate trustee costs a few hundred dollars to set up and removes the entire trustee problem on a death. Individual trustees are cheaper on day one and produce a compliance deadline in the month someone has died. If your fund still has individual trustees, that is the thing worth changing.
FAQ
What happens to my SMSF when one of the members dies?
The fund continues, the trustee structure must be made compliant within a limited period, and the deceased's benefit must be cashed as soon as practicable as a lump sum or a death benefit income stream.
Can the surviving member be the sole trustee?
Not with individual trustees — an SMSF needs at least two. A corporate trustee with a sole director is permitted, which is the strongest practical argument for using one from the start.
Who decides where the benefit goes?
A valid binding death benefit nomination directs it. Without one, the surviving trustee decides, and in an SMSF that person frequently has an interest in the outcome.
