Hi TCtjh,
I am sorry for your loss. You can request a copy of your mother's will from the executor (if you know who they are) or from the law firm your mother used to draft the will. You can do this at any time after death, even if probate has not been granted (i.e. will not validated by court). If the executor has applied for probate, you can also obtain a copy of the will from the probate office in the Supreme Court of QLD after the granting of probate as a copy will be kept in with court.
Have a read of:
"Are you a beneficiary of a will? Know your rights"
Once someone passes, the executor must prepare accounts, advertise to existing and potential creditors to see if there are any amounts outstanding. Usually, the executor allows one month from date of advertising for creditors to contact estate and prove their debt. There are also actions to take for obtaining probate (validating the will from court). Potential, but unprovided for or insufficiently provided for, beneficiaries also get time under statute to dispute existing beneficiary shares. Hence, it is not unusual for distribution to take place 6-12 months from the date of death.
