Supported Decision Making Ohio: Alternatives to Guardianship for Adults with Disabilities

When a young adult with a disability turns 18 in Ohio, they gain full legal decision-making authority. Many families immediately assume they need guardianship to protect their child. But guardianship strips civil rights — potentially the right to vote, marry, choose where to live, or enter into contracts — and Ohio law requires that every less restrictive alternative be explored before a court can grant it.

The question isn't "should we get guardianship?" It's "what alternatives exist, and is guardianship actually necessary after we've tried them?"

What Supported Decision-Making Looks Like

Supported decision-making (SDM) keeps the young adult as the legal decision-maker while giving them structured help from trusted people. Instead of a guardian making decisions for the individual, a supporter helps them understand information, weigh options, and communicate their choices.

In practice, this might look like a parent reading through lease terms and explaining them before the young adult signs, or a sibling accompanying them to a medical appointment to help process what the doctor says. The young adult makes the decision — the supporter helps them get to an informed one.

Ohio's Current Legal Landscape

Here's the catch: Ohio does not yet have a comprehensive enacted supported-decision-making agreement statute. SDM is widely practiced informally, and several narrower legal tools exist to formalize decision-making support, but there's no single standardized state SDM form that courts and third parties are required to recognize.

Senate Bill 35 (136th General Assembly) would change this. The bill:

• Establishes a formal presumption of capacity for adults with developmental disabilities
• Creates a legally recognized "supported decision-making plan" that the individual (the principal) voluntarily executes with designated adult supporters
• Allows supporters to help the principal understand information, communicate decisions, and access records

SB 35 was introduced and referred to the Children and Human Services Committee on October 22, 2025, and remains pending legislative passage.

Tools Available Right Now

While SB 35 is pending, Ohio families can use several existing legal tools to provide decision-making support without resorting to guardianship:

Durable General Power of Attorney — The young adult signs a document granting a designated agent authority to handle financial transactions, sign contracts, and manage bank accounts. "Durable" means it remains effective if the individual becomes incapacitated. This must be signed while the individual has the legal capacity to understand what they're signing.

Healthcare Power of Attorney — Authorizes a designated agent to make medical decisions and access medical records if the young adult is unable to give informed consent. This covers the medical side of decision-making without touching financial or educational decisions.

Educational Power of Attorney / Privacy Release — Allows parents or advocates to continue participating in IEP meetings, accessing educational records, and assisting the student in signing IEP documents after age 18. This is particularly important for students who remain in school past 18 under diploma deferment.

Authorized Decision Maker (DD System) — Under Ohio Department of Developmental Disabilities administrative rules, an adult receiving county board services who doesn't have a guardian can formally authorize another adult to make decisions about their developmental disability programs and services. The representative must be an adult with no financial interest in the services.

IDEA Special Rule — If a student hasn't been declared incompetent but is determined to lack the ability to provide informed consent regarding their educational program, a parent can be appointed to represent their educational interests under Part B of IDEA. This doesn't require a probate court petition.

When Guardianship Is Actually Necessary

Guardianship should be considered only when the young adult genuinely lacks the cognitive capacity to understand the consequences of signing legal documents or their safety is seriously compromised, and the less restrictive tools above cannot manage the situation.

Ohio probate courts must verify — before granting any guardianship petition — that all alternatives have been explored and proven inadequate. Showing up to probate court with a petition but no evidence that you've tried powers of attorney, authorized decision-maker designations, or other tools will not go well.

If guardianship is genuinely needed, Limited Guardianship should be the first option explored. A limited guardianship restricts the guardian's authority to specific domains (medical decisions, for example) while leaving all other rights intact. The young adult keeps the right to vote, marry, and make their own choices in every area not covered by the court order.

Full guardianship — covering all domains of decision-making — should be a genuine last resort.

Filing costs vary by county: Cuyahoga County charges approximately $175 and Franklin County approximately $189 for an adult guardianship filing. Attorney fees are separate and can range from $2,000 to $5,000+ depending on complexity.

Start the Conversation Before 18

The worst time to figure out decision-making authority is after the 18th birthday, when the transfer of rights has already happened and a crisis forces a rushed probate filing.

Start the conversation at 16 — ideally when the OEDI redetermination is happening at the County Board. By 17, the IEP should document the family's plan for decision-making support after 18. If powers of attorney are the right fit, have them drafted and signed before the birthday.
