Wills
Contact their solicitor or the executor named in the will; apply for Probate or Letters of Administration via the Supreme Court in the relevant state or territory
Some steps differ by region inside the country.
Where
Their solicitor, the Public Trustee in their state or territory, a bank safe custody service, or a home safe.
How
Search home files and safes for the original will and any codicil.
Phone any solicitor whose name appears in their papers or bank payments.
Contact the Public Trustee, since many Australians made a will there and never mentioned it.
If no will is found, the estate is distributed under the intestacy rules of the relevant state or territory.
What to bring
