Supported decision making is often introduced as a humane alternative to guardianship. That description is useful, but incomplete. The deeper question is whether law and institutions can recognise the agency of a person who makes decisions with assistance. This is not merely a question of personal support. It is a question about the design of legal authority.
Australia and the United States approach this question from different starting points. Australia ratified the Convention on the Rights of Persons with Disabilities in 2008. The United States signed the Convention in 2009 but has not ratified it. Australia therefore works within a formal international obligation concerning equal recognition before the law, while reform in the United States is driven principally through state law, federal disability policy, constitutional values and advocacy. Yet the institutional problem is remarkably similar in both countries.
Two legal vocabularies, one practical question
Terminology can obscure the common ground. Australian law usually speaks of guardianship for personal matters and administration for financial matters. In the United States, guardianship may cover personal decisions, while conservatorship is used in some states for property or financial affairs. The language and legal effect vary from state to state. A comparative account must therefore resist the temptation to treat either country as a single system.
The common question is more direct. When a person needs help to understand information, weigh options or communicate a decision, will a bank, hospital, service provider, lawyer or court recognise that person as the decision maker? If the answer depends entirely on the goodwill of an individual employee, supported decision making remains precarious.
The United States shows the value of diverse legal pathways
The United States does not have one national supported decision making statute. Reform has developed through state legislation, court practice, disability advocacy and professional guidance. The National Resource Center for Supported Decision Making maps this state-based variation.
This diversity produces inconsistency, but it also creates a laboratory of legal design. Some states formally recognise supported decision-making agreements. Others require courts to consider less restrictive alternatives before appointing a guardian. The 2017 Uniform Guardianship, Conservatorship, and Other Protective Arrangements Act promotes person-centred planning and the least restrictive means available. These approaches direct attention to what should occur before substitute authority is imposed.
Australia can learn from this emphasis on multiple entry points. Support should not become available only after a tribunal process has begun. A person may need a trusted supporter at a bank meeting, during a health consultation, when entering a service agreement or when communicating with a public agency. A framework that recognises voluntary support before crisis may reduce the pressure for a formal guardianship or administration order later.
Recognition by third parties is the real threshold
A support arrangement has little practical value if third parties do not know what it means. Institutions are understandably concerned about fraud, privacy, undue influence, legal liability and the validity of transactions. Those concerns cannot simply be dismissed as resistance. They must be answered through clear authority, proportionate safeguards and usable procedures.
This is where some United States statutes offer an important lesson. Formal recognition can tell a third party what a supporter may do, what the supporter may not do, when information may be disclosed and when suspected abuse must be reported. It can also make clear that assistance does not transfer the final decision to the supporter. The person remains the legal actor.
Australia has articulated strong national principles. The Australian Law Reform Commission National Decision Making Principles emphasise an equal right to make decisions, access to necessary support, and respect for a person’s will, preferences and rights. The challenge is to translate those principles into a routine answer for the frontline worker who must decide whether and how to engage with a supporter.
Australia also has lessons for the United States
Learning should not travel in only one direction. Australian reform has placed considerable emphasis on will and preferences rather than a general assessment of best interests. That distinction matters. It requires decision makers to begin with the person’s own values, relationships, history and expressed choices. It also exposes the limits of a system that treats protection as an automatic justification for control.
Public tribunals, statutory guardians and public advocates can also provide forms of oversight that are less consistently available across the United States. The central Australian contribution is therefore not a claim that our system has solved supported decision making. It is the insistence that legal capacity reform must be connected to rights, review and public accountability.
The next Australian step is implementation architecture
The Disability Royal Commission devoted seventeen recommendations to supported decision making and the reform of guardianship and administration laws, policies and practices. The 2025 national progress report recorded broad acceptance in principle of national supported decision making principles, while implementation remained in progress. This is a familiar reform moment. Agreement at the level of principle is significant, but it is not the same as institutional change.
A serious implementation architecture would provide accessible agreements, trained supporters, clear privacy rules, guidance for banks and health services, pathways for review, remedies for misuse, and public data about uptake and outcomes. It would also fund support. If the legal model assumes that every person has a capable and available family member who can act without payment, it will reproduce existing inequality.
The most useful lesson from the United States is therefore not that Australia should copy a particular statute. It is that support can be given legal form at several points before guardianship. The most useful lesson from Australia is that any such form must remain anchored in the person’s will, preferences and rights.
The success of supported decision making should not be measured by the elegance of the statute. It should be measured by whether the person is heard, whether institutions can act on the decision, whether risk is managed without unnecessary control, and whether substitute authority is genuinely a last resort.

Where does your organisation still require a substitute decision maker when practical support could allow the person to decide?
