Overview
When a child with a disability approaches their 18th birthday, families often hear the same advice from well-meaning professionals: “You need to get guardianship.” And while guardianship is the right choice for some families in some circumstances, it is not the only option, and for many individuals with disabilities, it is not the best one.
Guardianship is a legal process that removes a person’s legal rights and transfers decision-making authority to someone else. It is powerful, it is often permanent, and it is frequently pursued by families who didn’t know alternatives existed. Washington State law now explicitly requires courts to consider alternatives to guardianship before granting it and those alternatives are worth understanding before any family makes a decision.
This page is a plain-language guide to the full spectrum of decision-making options available to families in Washington State, from the least restrictive to the most restrictive, so families can make an informed choice that fits their family member’s actual needs and abilities.
One important note: Guardianship and legal planning involve complex legal decisions that affect a person’s fundamental rights. This page is educational and not legal advice. Before making any decision, consult with a special needs attorney and contact the free legal resources listed at the bottom of this page.
Why This Decision Matters
When a person turns 18 in Washington State, they are legally an adult, regardless of disability. That means:
- Doctors, schools, and agencies cannot automatically share information with parents without the adult’s consent
- Parents cannot automatically make medical decisions on their child’s behalf
- Financial accounts in the adult’s name belong to them, not their parents
These changes can feel alarming, and they prompt many families to immediately pursue guardianship as a solution. But the question isn’t whether your family member needs support. It’s what kind of support, and how much legal authority actually needs to change hands to provide it.
The right answer depends on your family member’s specific abilities, the areas of life where they need help, and how much independence they can exercise with appropriate support.
The Spectrum of Options: Least to Most Restrictive
Option 1: Supported Decision-Making Agreement (SDMA)
The least restrictive option and the one most aligned with disability rights principles. Washington State formally recognized Supported Decision-Making in law in 2020 (effective January 1, 2022, under RCW 11.130.700–11.130.755), making Washington one of 13 states with legislation explicitly recognizing SDMAs.
How it works: The individual with a disability retains all of their legal rights. They sign a voluntary agreement naming one or more supporters, trusted people like family members, friends, or professionals, who help them understand information, evaluate options, and communicate decisions. The individual makes the final decision. The supporter helps them get there.
Third parties, doctors, banks, landlords, schools, are required to recognize the person’s authority to make their own decisions, with their supporter present or involved as specified in the agreement.
What supporters do:
- Help explain complex information in accessible ways
- Research options and present them clearly
- Accompany the person to appointments and meetings
- Help communicate decisions to others
- Advocate for the person’s expressed wishes
What supporters don’t do: Make decisions for the person. The individual always retains final decision-making authority. If a supporter’s advice and the individual’s preference differ, the individual’s decision controls.
How to create one: An SDMA does not require court approval. The agreement is signed by the individual and their supporters, specifying which areas of life the supporters help with. DRW and Washington LawHelp provide free templates and guidance.
Best for: Individuals who, with support, can take in information, evaluate it, make decisions, and communicate those decisions effectively. Many individuals with intellectual and developmental disabilities can do exactly this with the right support.
Cost: Free, no court involvement required.
Option 2: Durable Power of Attorney (POA)
A legal document in which a person voluntarily gives another person (the agent) authority to make decisions on their behalf in specified areas, typically financial decisions, medical decisions, or both. Unlike guardianship, POA is voluntary, the individual must have legal capacity to sign it.
Types:
- General Durable Power of Attorney: covers financial and legal decisions; remains in effect if the person becomes incapacitated
- Healthcare Power of Attorney / Healthcare Directive: designates someone to make medical decisions if the person cannot do so themselves; can also include a living will specifying care preferences
Key distinction from guardianship: The person retains their legal rights. They are voluntarily delegating authority in specific areas, not having authority removed by a court.
Timing matters: A POA must be signed while the person has legal capacity. If capacity is lost before a POA is established, guardianship may become the only remaining path for that area of decision-making. This is why families should consider POA options before a young adult turns 18 if this route is appropriate.
Best for: Individuals who have capacity to sign legal documents and want to designate trusted people to help with specific decisions.
Cost: Can be completed with a special needs attorney (typically $300–$1,500) or through free legal aid resources for income-eligible families.
Option 3: Representative Payee
A narrowly scoped arrangement for managing Social Security benefits (SSI or SSDI) only. A Representative Payee is appointed by the Social Security Administration to receive and manage Social Security payments on behalf of an individual who needs help managing their benefits, paying for food, housing, and other needs.
This is not guardianship. A Representative Payee controls only Social Security income, not all finances, not medical decisions, not living arrangements.
How to become a Representative Payee: Apply through the Social Security Administration. Family members, friends, and organizations can serve as Representative Payees.
Best for: Individuals who receive SSI or SSDI and need help managing those funds specifically, without broader decision-making intervention needed.
Cost: Free.
Option 4: Limited Guardianship
When some level of court-ordered decision-making authority is genuinely needed, Limited Guardianship is a less restrictive alternative to Full Guardianship. Rather than removing all legal rights, Limited Guardianship removes only specific, identified rights in areas where the individual truly cannot make decisions and leaves all other rights intact.
For example, a Limited Guardian might be authorized to make medical decisions but not financial decisions, or to make housing decisions but not personal decisions about relationships and activities.
Washington law requires courts to grant the least restrictive arrangement necessary, meaning a court should not grant full guardianship if limited guardianship would meet the need.
Best for: Individuals who need court-backed decision-making authority in specific, defined areas of life but retain capacity in others.
Cost: Court filing fees plus attorney fees, typically less than full guardianship but still involves legal process. Free legal resources may be available for income-eligible families.
Option 5: Full Guardianship
Full Guardianship is a court process that removes an adult’s legal rights and transfers decision-making authority to a Guardian (for personal decisions like health, living arrangements, activities) and/or a Conservator (for financial decisions). It is a judicial finding of legal incapacity.
What full guardianship means:
- The individual loses the right to make their own medical decisions
- The individual loses the right to decide where they live
- The individual may lose the right to vote, marry, or enter contracts
- The guardian has legal authority to make decisions on their behalf
- Court oversight is required — the guardian must file annual reports
What full guardianship does not mean:
- It does not mean the person has no voice. Good guardians involve the person in every decision possible and honor their preferences.
- It is not necessarily permanent, guardianship can be modified or terminated if circumstances change, though this requires returning to court.
When full guardianship may be appropriate: When an individual truly cannot make decisions in a particular area even with robust support, and when less restrictive alternatives have been genuinely considered and found insufficient.
Cost: Typically $3,000–$10,000+ in attorney and court fees to establish, plus ongoing costs for annual reports and any modifications.
Washington law requirement: Courts must now explicitly consider alternatives to guardianship before granting it. Families pursuing guardianship should be prepared to explain why less restrictive alternatives were considered and found insufficient.

What to Do as Your Family Member Approaches 18
The transition to adulthood is the most common trigger for guardianship conversations and the most important time to think carefully before acting. Here’s a practical approach:
- Start early. Begin this conversation at 16 or 17, not the week before the 18th birthday.
- Assess the actual need. In which specific areas does your family member need support? Medical decisions? Financial management? Housing choices? Or primarily just help navigating complex systems?
- Try supported decision-making first. If your family member can make decisions with support, an SDMA may be sufficient and preserves their rights completely.
- Consult a special needs attorney. An attorney with experience in disability law can help you evaluate the right option for your specific situation and family member’s needs and abilities.
- Contact free legal resources. DRW and NJP can both provide guidance at no cost before you invest in a full legal process.
- Involve your family member. Their voice, preferences, and wishes should be central to this decision — not an afterthought.
