Supported Decision Making vs Guardianship Oregon: Which Is Right at 18
What Changes at 18
On the eighteenth birthday, every Oregon student with a disability becomes a legal adult with full decision-making authority over their education, healthcare, and finances. All procedural safeguard rights under IDEA — the right to consent to evaluations, approve IEP goals, and access records — transfer automatically from the parent to the student.
Oregon school districts must notify both the parent and student of this transfer at least one year before the student turns 18. The notification typically happens at the IEP meeting during the student's seventeenth year.
For many families, this transfer creates an immediate tension: the young adult has legal authority over decisions they may not yet have the experience or capacity to make independently, but removing that authority through guardianship is expensive, permanent, and — Oregon courts insist — a last resort.
Supported Decision-Making Under HB 2105
Oregon House Bill 2105, effective January 1, 2022, formally recognizes supported decision-making (SDM) as a less restrictive alternative to guardianship within the education system. The law requires school districts to:
- Provide written information about SDM at every IEP meeting where post-secondary goals and transition services are discussed
- Offer training and resources on SDM to families
- Include SDM in transition-planning discussions
An SDM agreement designates one or more supporters — usually parents, siblings, or trusted adults — who help the individual understand information, weigh options, and communicate decisions. The individual retains full legal authority. The supporter advises; the individual decides.
The agreement can cover specific areas (medical decisions, financial transactions, educational choices) or be broad. It can name different supporters for different domains — a parent for healthcare decisions, a sibling for financial matters.
The Cross-Sector Gap
Here is where Oregon's SDM framework has a significant limitation: HB 2105 operates within the educational system. Oregon does not have a comprehensive, cross-sector civil SDM statute that legally requires private third parties — banks, landlords, medical providers, employers — to recognize and honor an SDM agreement.
This means a school district must provide the required SDM information and resources in transition planning. But a bank may refuse to allow a supporter into a meeting about the individual's accounts. A doctor may decline to discuss treatment options with a supporter who is not named on a HIPAA authorization. A landlord has no legal obligation to include a supporter in lease negotiations.
The gap does not make SDM useless outside of education — many private entities will voluntarily work with an SDM arrangement, especially when presented professionally. But it means SDM alone may not provide the legal authority families need for all aspects of adult life.

Tools That Fill the Gap
Because Oregon's SDM law does not extend across all sectors, families typically combine SDM with other legally recognized instruments:
Powers of Attorney (POA): the young adult executes a durable or limited power of attorney, authorizing a specific person to act on their behalf for defined purposes. A financial POA can authorize a parent to manage bank accounts, sign leases, or handle tax filings. A healthcare POA (or advance directive) designates a healthcare representative to make medical decisions during periods of incapacity.
HIPAA Authorization: a signed release allowing specific supporters to access the individual's medical records and communicate with healthcare providers. A HIPAA authorization makes the supporter's access clear; without one, a provider may limit what it discloses to that supporter.
FERPA Release: for individuals still in post-secondary education, a signed authorization allowing parents or supporters to access educational records.
Representative Payee: for SSI recipients who need help managing their benefit payments, the SSA can appoint a representative payee to receive and manage the monthly check on the individual's behalf.
The combination of SDM + POA + HIPAA release covers most daily decision-making situations without removing the individual's legal rights.
When Guardianship Is Necessary
Oregon courts treat guardianship as a last resort. Under ORS Chapter 125, a petitioner must demonstrate that:
- The individual lacks the capacity to make decisions in the specific area(s) where the guardian's authority is sought
- Less restrictive alternatives (SDM, POA, advance directives) have been explored and found insufficient
- The proposed guardian is suitable and willing to serve
Oregon allows limited guardianship — a court can restrict the guardian's authority to specific domains (healthcare decisions, financial management, residential placement) rather than granting full authority over all areas of the individual's life.
Guardianship may be the right path when:
- The individual cannot understand the concept of delegation (cannot meaningfully execute a POA)
- Medical providers or financial institutions refuse to honor POA or SDM arrangements due to the individual's level of incapacity
- The individual is at risk of exploitation that SDM cannot prevent
- The individual needs a legal decision-maker for medical emergencies where advance directives are insufficient
Guardianship Costs in Oregon
Filing a guardianship petition in Oregon Circuit Court costs $124 in filing fees statewide. Beyond the filing fee, costs include:
- Court visitor fee: the court appoints a visitor (an independent investigator) who interviews the individual, the proposed guardian, and other relevant parties. Fees vary by county — Multnomah County charges $750, Columbia County $400, Lane County $300.
- Attorney fees: most guardianship attorneys in Oregon charge $3,500-$10,000 for a standard uncontested petition. Contested guardianships (where someone objects) cost significantly more.
- Ongoing reporting: guardians must file annual reports with the court, which some families prepare themselves and others have an attorney assist with ($500-$1,500 per filing).
Legal aid organizations in Oregon — including Disability Rights Oregon and Legal Aid Services of Oregon — may provide free or reduced-cost guardianship assistance to income-eligible families.
The Practical Decision Framework
The decision between SDM and guardianship is not binary. Most Oregon families at the age-18 transition use a layered approach:
- Start with SDM and the supporting legal tools (POA, HIPAA, FERPA releases)
- Test whether these arrangements work in practice — do the bank, the doctor's office, and the school accept the supporter's role?
- Pursue limited guardianship only in specific domains where the less restrictive tools are demonstrably insufficient
This approach satisfies Oregon courts' requirement that alternatives be explored first, preserves the young adult's autonomy to the greatest extent possible, and costs significantly less than filing for full guardianship immediately.
