Supported decision-making: an alternative to guardianship

For most of the twentieth century, the legal response to a person's incapacity to make decisions because of serious mental illness was the same: appoint someone else to make decisions for them. Guardianship and conservatorship remain the dominant legal framework in the United States, despite well-documented harms — loss of voting rights, loss of autonomy over money and medical care, and the difficulty of getting out of guardianship once it is in place. Supported decision-making (SDM) is a different model. Instead of replacing the person's voice with someone else's, it surrounds the person with the help they need to make and communicate their own decisions.

The legal and ethical backdrop

The international momentum behind SDM comes from Article 12 of the UN Convention on the Rights of Persons with Disabilities (CRPD), which states that people with disabilities have the right to legal capacity on an equal basis with others, and that states must provide access to support in exercising that capacity. The CRPD interprets traditional substitute decision-making (guardianship) as inconsistent with disability rights and calls on states to develop SDM alternatives.

The US has not ratified the CRPD, but the model has spread anyway. As of 2026, more than fifteen US states have passed SDM legislation, and many more recognise SDM agreements administratively.

How SDM works in practice

An SDM agreement is a written document — sometimes legally formalised, sometimes not — in which a person identifies one or more supporters and specifies the kinds of decisions they want help with. The supporter does not make decisions for the person. Their role is to:

• Help the person gather and understand information
• Talk through options and consequences
• Help the person communicate their decision to others (clinicians, banks, landlords, courts)
• Sometimes accompany the person to appointments

The decision itself remains the person's. Third parties (like a doctor or a bank) are expected to recognise the supporter's role while still treating the person as the legal decision-maker.

Why SDM matters in schizophrenia

For people with schizophrenia, SDM addresses several common situations:

• Periods of partial capacity, where the person can make decisions with help but might be denied that opportunity if there were no formal support
• Avoiding full guardianship, which can be unnecessarily restrictive
• Building consistent support across treatment, finances, and housing
• Documenting preferences for psychiatric care during stable periods

The model is closely tied to the broader recovery movement, which emphasises self-determination, peer support, and the idea that people with serious mental illness are experts on their own lives.

SDM and psychiatric advance directives

SDM works hand-in-hand with psychiatric advance directives (PADs) — documents in which a person specifies, in advance, their preferences for treatment during a future crisis (preferred medications, preferred hospitals, who should be contacted, what de-escalation strategies have worked before). PADs are recognised in most US states. SDM provides the supporter network that can help honour those preferences in real time.

What the evidence shows

Research on SDM in serious mental illness is still developing, but evidence so far suggests that:

• People who use SDM report greater satisfaction with treatment decisions
• SDM is associated with higher engagement with services
• Pilot programmes (in Texas, Massachusetts, Australia, Canada, and parts of Europe) have shown that SDM is feasible across a wide range of cognitive and psychiatric profiles
• Concerns about coercion or abuse by supporters can be mitigated by thoughtful agreement design and oversight

The strongest evidence base is in intellectual and developmental disability; the mental illness evidence base is younger but growing rapidly.

What SDM looks like for a family

For families, SDM is often a more workable alternative to fighting for or against guardianship. Practical steps include:

• Sit down during a calm period and identify which kinds of decisions the person would like help with (medication, housing, finances, work)
• Identify one or more supporters — often family members, but can include friends, peers, or professionals
• Write a simple agreement, even informally; many state SDM laws provide templates
• Combine with a psychiatric advance directive for crisis-period preferences
• Share the documents with the treatment team and key institutions

Where SDM is harder

• During acute, severe psychosis, the person may temporarily not be able to engage in even supported decisions — which is why combining SDM with a PAD matters
• Some institutions (banks, hospitals, courts) are still unfamiliar with SDM and may push back
• Supporters can feel uncertain about their role and may benefit from training
• SDM does not solve genuine clinical disagreements; it formalises whose voice matters

SDM vs guardianship — the comparison

• Guardianship removes legal decision-making authority and assigns it to another person. It is a court order, often hard to reverse, and can affect voting, marriage, and other civil rights.
• SDM preserves legal decision-making authority and adds a structured support network. It is created by the person and can be modified at will.

For people whose capacity is partial or fluctuates, SDM is often the better fit. Even in cases where some form of substitute decision-making is needed, courts in many US states are now required to consider less restrictive alternatives (including SDM) before ordering guardianship.

Where to learn more

The National Resource Center for Supported Decision-Making maintains state-by-state resources and templates. NAMI provides information for families. State protection and advocacy agencies can often advise on local law.

The honest summary

Supported decision-making is one of the most important quiet shifts in disability and mental health law over the past two decades. It does not solve every problem, and it does not eliminate the need for crisis-period interventions. What it does is restore — and protect — the principle that a person with schizophrenia is, first and foremost, the author of their own life. Building an SDM arrangement during a stable period is one of the most useful things a family and a person with serious mental illness can do together.
