You've probably been helping your child make decisions for years. Walking through medical choices together. Talking through job opportunities. Discussing where and with whom they want to live.

What you've been doing informally is the foundation of supported decision-making. It's a legal framework that formalizes your role as a supporter without stripping your child of their decision-making rights.

Many parents approaching their child's 18th birthday face what feels like a binary choice: pursue full guardianship or do nothing. Supported decision-making offers a third path.

What Supported Decision-Making Is

Supported decision-making (SDM) is a process where adults with disabilities choose trusted people to help them understand situations, weigh options, and communicate their decisions. The person with a disability retains all legal rights. The supporter doesn't make decisions for them.

The principal identifies specific areas where they want help: healthcare, finances, housing, employment, education. They choose supporters they trust: parents, siblings, friends, mentors. Those supporters help them understand choices and consequences, but the principal makes the final call.

This differs fundamentally from guardianship, where a court transfers decision-making authority to a guardian. Under guardianship, the person loses legal rights. Under SDM, they keep them.

Texas became the first state to recognize supported decision-making agreements in 2015. Since then, at least 21 states have passed SDM laws. Illinois enacted its Supported Decision-Making Act in 2022. Virginia formally recognized SDM agreements as an alternative to guardianship under Virginia Code § 37.2-314.3.

When SDM Works Better Than Guardianship

Supported decision-making works when the person can express preferences, understand consequences with help, and has people they trust who can commit to supporting them.

It's not appropriate in every situation. If someone can't participate in decisions even with extensive support, or if there's significant disagreement among family members about what the person wants, guardianship might be necessary. If the person is at immediate risk and can't recognize it, the court may determine that substitute decision-making is required.

But many families pursue guardianship because they don't know SDM exists. They assume it's the only way to help their adult child navigate healthcare systems, manage finances, or sign contracts. SDM addresses those needs while preserving autonomy.

Parents often worry: what if my child makes a bad decision? That's a legitimate concern. But adults without disabilities make bad decisions too. The legal standard isn't perfection. It's capacity to understand choices with support.

How to Set Up a Supported Decision-Making Agreement

Choose the Areas of Support

Start by identifying where your child wants help. Common areas include:

• Healthcare decisions (choosing doctors, understanding treatment options, managing medications)
• Financial management (budgeting, paying bills, understanding bank accounts)
• Housing (lease agreements, roommate situations, home modifications)
• Employment (job applications, workplace accommodations, understanding benefits)
• Education (college applications, course selection, disability services)

Your child decides which areas they want support in. You don't choose for them.

Select Supporters

The principal chooses who they want as supporters. This might be one person who helps with everything, or different people for different areas. A parent might help with healthcare decisions. A sibling might help with housing. A financial planner might help with budgeting.

Disability Rights Texas recommends having conversations about what support looks like before formalizing anything. What does your child want help with? How do they want to receive that help: someone explaining options, attending meetings with them, reviewing documents together?

Draft the Agreement

A supported decision-making agreement outlines:

• The principal's name
• The supporter's name and contact information
• Specific decisions or areas where support is needed
• What information the supporter can access (medical records, financial statements, educational records)
• How the supporter will help (explaining options, attending meetings, reviewing documents)
• When the agreement starts and whether it has an end date
• How the agreement can be changed or ended

Many states provide template forms. Disability rights organizations offer free templates. You can also work with an attorney familiar with SDM in your state.

The agreement should be specific. "Help with healthcare" is vague. "Attend doctor appointments, explain treatment options, help me understand medical forms, and communicate my decisions to healthcare providers" is clear.

Sign and Witness the Agreement

Requirements vary by state. In most states with SDM laws, the principal and supporter sign the agreement in front of two witnesses who are at least 18 years old. The witnesses can't be supporters named in the agreement. Some states require notarization instead of witnesses.

Check your state's specific requirements. If your state has an SDM law, follow its procedures. If your state doesn't have a law yet, you can still create an agreement. It might not have the same legal recognition, but it documents your child's preferences and can guide supporters.

Share the Agreement

Once signed, give copies to anyone who needs to recognize the supporter's role: doctors, banks, schools, employers, landlords. The agreement authorizes them to communicate with supporters and include them in discussions while understanding the principal makes the final decision.

Healthcare providers must comply with HIPAA, which limits who can access medical information. An SDM agreement that specifically authorizes a supporter to access health records addresses this.

What Supporters Can and Can't Do

Supporters can explain options, attend meetings, access information specified in the agreement, help the principal communicate their decisions to others, and remind the principal about upcoming deadlines or appointments.

Supporters can't make decisions for the principal, override the principal's choices, sign legal documents on behalf of the principal, or access information not specified in the agreement.

If a supporter acts beyond their role, the principal can revoke the agreement. SDM is voluntary. The person being supported can end it at any time.

State-by-State Differences

As of 2026, more than 20 states have enacted supported decision-making laws. Each state's law differs in details.

Some states require specific agreement forms. Others accept any written agreement that meets basic requirements. Some states limit who can serve as a supporter (excluding paid caregivers or service providers). Others don't restrict it.

Colorado's law defines how SDM agreements interact with guardianship proceedings. Courts must consider whether SDM is a less restrictive alternative before appointing a guardian.

If you live in a state without an SDM law, you can still create an agreement. It won't have statutory recognition, but it serves as documentation of your child's preferences and can be presented to service providers, schools, and healthcare facilities. Many organizations recognize informal SDM agreements even without state law mandating it.

Check with your state's disability rights organization for current information about SDM laws in your area.

SDM and Other Legal Tools

Supported decision-making works alongside other planning tools. Your child can have an SDM agreement and also create:

• A durable power of attorney for specific financial matters
• An advance healthcare directive outlining medical preferences
• A HIPAA authorization allowing specific people to access health information

SDM doesn't replace these tools but works alongside them. Power of attorney transfers decision-making authority in specific areas. SDM keeps authority with the person while adding structured support.

Some families use SDM for most areas and limited guardianship for one specific area where substitute decision-making is genuinely necessary. The goal is the least restrictive option that meets actual needs.

If SDM Isn't Working

SDM agreements can be changed. If the areas of support need adjustment, if a supporter needs to be replaced, or if the level of support isn't working, you can modify the agreement.

If SDM proves insufficient after trying it, guardianship remains an option. Courts generally prefer seeing that less restrictive alternatives were attempted before ordering guardianship. Having tried SDM doesn't prevent pursuing guardianship later if circumstances require it.

The reverse is harder. Terminating or modifying guardianship requires going back to court and demonstrating that the person no longer needs substitute decision-making. Starting with SDM preserves more options.

Taking the First Step

If your child is approaching 18 and you're trying to figure out what legal protections they need, start with a conversation. Ask them which areas of their life they want help with. Ask how they want that help to look.

You might find you're already doing supported decision-making. Formalizing it through an agreement gives it legal recognition and helps others understand your role.

Download a template agreement for your state. Sit down together and fill it out. Talk through each section. If something doesn't feel right, adjust it. The agreement should reflect what works for your family, not a generic checklist.

Schedule a time to sign it with witnesses present. Make copies. Set up a meeting with your child's primary care doctor to share the agreement and explain how it works. Do the same with their bank, school, or employer.

Supported decision-making isn't perfect for every situation. But for many families, it's the option that respects both autonomy and the real need for support.
