Supported Decision-Making in New York

What Supported Decision-Making Does

When a young person with a developmental disability turns 18 in New York, they become a legal adult with full decision-making authority — regardless of the nature or severity of their disability. Parents who have been signing consent forms, managing medical appointments, and making financial decisions on their child's behalf suddenly have no legal standing to continue doing so.

Supported Decision-Making (SDM) is the mechanism New York created to address this without stripping the young adult's rights through court-ordered guardianship. Under Mental Hygiene Law Article 82, an adult with an intellectual or developmental disability can designate trusted people — called supporters — to help them gather information, weigh options, and communicate decisions. The individual retains full legal capacity. They make the decisions. The supporters assist but do not decide.

The Legal Framework: MHL Article 82 and 14 NYCRR Part 634

New York formalized SDM through Mental Hygiene Law Article 82, and the implementing regulations under 14 NYCRR Part 634 took effect on August 20, 2025. These regulations transformed SDM from a philosophical concept into an enforceable legal instrument.

The critical legal consequence: once a properly executed Supported Decision-Making Agreement is in place, third parties — banks, hospitals, schools, landlords, service providers — are legally required to recognize the decisions made with the assistance of the SDMA. They cannot refuse to deal with the individual simply because they have a disability, and they are protected from liability for actions taken in reliance on the agreement.

Before these regulations, families often encountered pushback from institutions that claimed they could not accept decisions from a person with a developmental disability without a guardian's involvement. That argument no longer holds in New York.

Requirements for a Valid SDMA

Under MHL § 82.10, a Supported Decision-Making Agreement must meet specific formal requirements to be legally binding:

1. Written, dated, and signed by the decision-maker and all designated supporters
2. Lists specific categories of decisions where support is authorized (healthcare, finances, housing, employment, education, daily living)
3. Details the types of support each supporter will provide (helping gather information, explaining options, communicating the individual's choices to third parties)
4. Contains an attestation from each supporter that they will honor the individual's autonomy and will not make decisions for them or exert undue influence
5. Signed by an authorized facilitator or educator who certifies that the agreement was developed through a recognized facilitation process
6. Executed in the presence of two adult witnesses or a notary public

The facilitator requirement is where the process has teeth. The agreement cannot simply be drafted at the kitchen table and signed. An authorized facilitator — typically through AIM Services Inc., the designated statewide coordinator of SDM facilitation under OPWDD oversight — must guide the decision-maker through a structured process that ensures the agreement reflects their genuine preferences, not someone else's expectations.

How SDM Differs From Guardianship

The distinction is not a matter of degree — it is a fundamentally different legal framework.

SDM preserves legal capacity. The individual remains their own decision-maker. Supporters are advisors, not substitutes. The individual can revoke the agreement at any time, modify the scope, or replace supporters.

Guardianship removes or restricts legal capacity. Under Article 17-A, the court strips all decision-making rights based on a developmental disability diagnosis. Under Article 81, the court removes specific rights based on demonstrated functional limitations. Either way, someone else is making decisions for the individual, under court authority.

SDM has no court involvement. There is no filing, no judge, no hearing, no attorney appointment, no court fees. The agreement is executed privately between the decision-maker, their supporters, and the facilitator. Article 17-A guardianship costs a $20 filing fee plus medical certifications. Article 81 proceedings can cost $5,000 or more.

SDM can coexist with a representative payee. A parent can serve as the individual's representative payee for SSI benefits (managing the monthly check, reporting changes to the SSA) while the individual retains legal capacity for all other decisions through an SDMA. These two mechanisms address different needs and are fully compatible.

When SDM Is Sufficient — and When It Is Not

SDM works well when the individual can understand and communicate their preferences with support. The supporter helps them process information, but the individual drives the outcome. For many young adults with developmental disabilities, this is exactly the right model — they know what they want, they just need help navigating the bureaucratic and social complexity of adult life.

SDM may be insufficient when the individual genuinely cannot form or express preferences even with maximum support — when decisions need to be made on their behalf because they cannot participate in the process at all. In these situations, families may need to consider Article 17-A or Article 81 guardianship.

The important principle embedded in New York law: guardianship should be the last resort, pursued only after SDM and other less restrictive alternatives have been evaluated and found insufficient. Courts are required to consider these alternatives before granting a guardianship petition.

How to Get Started

The first step is contacting an authorized SDM facilitator. AIM Services Inc. operates as the statewide coordinator under OPWDD oversight and can connect families with the facilitation process. SDMNY (Supported Decision-Making New York) also provides resources and referrals.

The facilitation process typically involves several sessions where the decision-maker, their chosen supporters, and the facilitator work through each decision category — identifying where the individual wants support, what kind of help they need, and who should provide it.

Once the agreement is finalized and properly executed with the required signatures and witnesses, the family should provide copies to all relevant third parties: the individual's healthcare providers, financial institutions, school or employer, OPWDD Care Manager, and any other entity that interacts with the individual in a decision-making capacity.
