The Guardianship and Administration Act 1990 is the law that covers people who may need someone to make decisions for them in their finances (Administration) and other life areas (Guardianship).
DDWA is often contacted about Guardianship and Administration. These are the frequently asked questions.
What changes when my child turns 18?
- The child is legally considered an adult.
- As an adult they can make their own decisions about their life and finances.
However, if they do not have decision-making capacity, parents may still be able to make decisions on their behalf including making informal arrangements
What are Informal Arrangements?
This is usually the continuation of parental supports, as done before the age of 18, and can include Authorisation to act on behalf of an adult child, with Government Departments:
These are alternative ways to assist a person with a disability to engage with the supports they need for example:
- Centrelink Nominee
- Medicare Authorisation to Act on behalf
- NDIS Nominee
- WA Hierarchy of Treatment Decision-Makers (Health)
- Voting – registration or removal from electoral role if needed
- Banking – third party authority access to account
The appointment of a guardian is not necessary when informal arrangements can ensure the best interests of the person with a decision-making disability are being met if:
- The person with a decision-making disability can manage and maintain a reasonable quality of life for themselves.
- The person is being adequately supported and cared for by others.
- There are no personal or family conflicts about the person’s care and support needs.
- There are no major problems or issues that pose an immediate or imminent threat to the person’s quality of life.
- The person is being adequately supported and cared for by others.
- There are no personal or family conflicts about the person’s care and support needs.
- There are no major problems or issues that pose an immediate or imminent threat to the person’s quality of life.
Guardianship
What is Guardianship?
A guardian or administrator will be appointed only if it is established that there is no other appropriate way of meeting the person’s needs which would be less restrictive of their freedom of decision and action. This is called the least restrictive alternative.
A parent as guardian is usually viewed to be a less restrictive option than a Public guardian from the Office of the Public Advocate.
What is legal capacity?
This refers to whether a person is able to fully understand the decisions they need to make and the outcome of making those decisions.
All people are assumed to have legal capacity, unless there are concerns that they do not.
The assessment of legal capacity is usually done by a medical practitioner.
What is a decision-making disability?
A general term used to describe someone who has a disability which affects their ability to understand information and to make informed and reasonable decisions.
This may be as a result of:
- intellectual disability
- mental illness
- acquired brain injury
- dementia
- substance related brain damage
What does best interests mean?
A guardian acts in the best interests for the represented person if they:
- encourage them to live in the general community and participate as much as possible in the life of the community
- encourage and assist them to become capable of caring for themself and of making reasonable judgments in respect of matters relating to them.
- protect them from neglect, abuse or exploitation
- consult with them, considering as far as possible, the wishes of that person as expressed, in whatever manner
- act in the way that is least restrictive of their rights, while providing the proper protection for them
- maintain any supportive relationships they have
- maintain their familiar cultural, linguistic and religious environment.
Who can be a guardian?
A person can be a Guardian if they:
- over 18 years of age and have full legal capacity
- will preserve existing family relationships
- are compatible with the proposed represented person
- consider the wishes of the proposed represented person
- will be able to perform the functions of a guardian
- will act in the best interests of the proposed represented person
- they are not in a position where their interests conflict or may conflict with the interests of the proposed represented person
- they are otherwise suitable to act as the guardian.
What areas of life (Authorities) can a Guardian decide?
a. Where a person is to live, whether permanently or temporarily
b. With whom the person is to live
c. Make treatment decisions including restrictive practices
d. Services e.g. NDIS.
e. Whether the person should work and if so the nature of the type of work and matters related to work
f. What education and training the person is to receive
g. With whom the represented person is to associate
h. Commence, conduct or settle any legal proceedings on behalf of the represented person, except proceedings relating to the estate of the represented person
NB: Only the areas where decisions are needed will be given to a Guardian (Limited) unless all areas need to be covered (Plenary).
What can a guardian not decide?
- voting
- making or changing a will
- marriage
- sterilisation
- abortion
- adoption
Can you have more than one guardian?
You can have joint private guardians.
They must agree on all the decisions made for the represented person.
What are the guardianship options when I am gone, for my adult child?
The best way to plan for this is to have conversations with family/friends about your wishes for your child’s future guardianship/administration.
To confirm your plans, you could include this information with your Will as a ‘Statement of Wishes’.
For a person without legal capacity to make their own decisions, upon the death of their parent or legal guardian, a SAT application will be required to be made if another family member or friend agrees to take on this role.
What is an Enduring Power of Guardianship?
An Enduring Power of Guardianship (EPG) is a legal document allowing you to appoint another person to make personal, life, treatment and medical research decisions for you (like a Guardian can) if you become unable to do so. This person is known as your Enduring Guardian.
- A person with intellectual disability may appoint someone to act on their behalf under an Enduring Power of Guardianship.
- This can only be done by an adult with intellectual disability if they have legal capacity at the time it is signed.
How long does a guardianship order last?
- Guardianship orders range from 1 year up to a maximum of five years. (Sometimes they can be less than a year).
- All orders are reviewed before the end date, to decide if a new order should be made, or the order should be revoked (if the person no longer requires a guardian).
A review can be conducted before the end date if circumstances change if there is reason to do so.
How does a Private Guardian get advice?
The Office of the Public Advocate (OPA) is happy to have contact from Private Guardians to talk through a problem.
In rare situations, an application can be made to the State Administrative Tribunal for direction on what action should be taken.
The OPA provides a comprehensive information booklet about the role and duties of a Guardian. This is the link to the Private Guardians guide: https://www.wa.gov.au/system/files/2024-08/private-guardians-guide.pdf
Administration
What is an Administrator?
An Administrator (or Trustee) is appointed by SAT to make financial and legal decisions of a financial or estate nature in the best interests of someone not capable of making those decisions for themselves. An Administrator may be given authority to decide specific matters such as the sale of assets, payment of debts or investment of money.
Many Administrators have broad (plenary) authority and manage all of the person’s estate and financial affairs and pay all the daily bills, purchase all essential items and they must keep detailed accounts.
The Public Trustee provides guidance and support to Private Administrators concerning their roles and responsibilities They provide a comprehensive information booklet about the role and duties of an Administrator.
This is the link to download the Private Administrators Guide:
Who can be an Administrator?
- A person over the age of 18.
- A family member or other community member can be appointed as an Administrator if they can perform that role.
- The Public Trustee can be pointed as an Administrator of last resort if no one else is able to do it.

- A person with intellectual disability may appoint someone to act on their behalf under a Power of Attorney. This can only be done by an adult with intellectual disability if they have legal capacity at the time it is signed. The Power of Attorney will end if the person later loses legal capacity.
What is an Enduring Power of Attorney?
- An EPA contains the same features as a Power of Attorney, with the exception that it ‘endures’ or continues to operate after the person loses legal capacity.
- If you want to revoke (or cancel) an EPA an application to the SAT is required to do this.

- Considers applications for the appointment of a guardian and/or administrator.
- Makes orders for the appointment of guardians and administrators.
- Reviews orders which have been made previously.
- Considers applications to determine who should make a treatment decision.

- Whether consent is required for a Restrictive Practice.
