Assets and income assessment - joint tenants

I have tried to submit this before, but the question didn’t appear on the forum?
Question 49 on the Assessment form SA457 asks for home percentage owned.
My mother, myself and my sister are joint tenants for our home (Queensland).
The title search has no mention of percentages owned.
Do I show my mother owning 33.3% ?

Thanks very much Jill.Ted

My understanding Ted is that yes you each own 33.3% if equal shares unless stated otherwise.Jill
