Your child turns 18 in six months, and your attorney has started the guardianship conversation. You've heard the term for years. You know it means you retain legal authority to make decisions on your child's behalf. What you may not know is that guardianship also means your child loses nearly every legal right they have: the right to choose where they live, who they see, what medical care they receive, and whether they can marry.

For many families, that trade-off is necessary. But for many others, it's not. There's a spectrum of options between full guardianship and no legal support at all, and disability advocates now recommend starting with the least restrictive option first.

That option is called supported decision-making.

What Supported Decision-Making Is

Supported decision-making (SDM) is a formal agreement in which your child appoints a team of supporters to help them make decisions. The supporters don't make decisions for your child. They help your child weigh options, understand consequences, and arrive at their own choices.

It's the same process most adults use when they consult friends, family, or professionals before making a big decision. The difference is that SDM formalizes it. Your child retains all their legal rights. The supporters are there to assist, not to override.

Under an SDM agreement, your child can appoint you, a sibling, a trusted friend, or a professional to help with specific areas: healthcare, education, finances, or daily living decisions. Your child decides who helps and in what capacity. If your child later decides SDM isn't working, they can revoke the agreement and either try a different structure or pursue guardianship.

What Guardianship Is

Guardianship is a court process in which a judge appoints someone to make decisions on behalf of another person. In most cases, parents serve as guardians for their adult children with disabilities. Once guardianship is granted, the person under guardianship loses virtually all legal rights in the areas covered by the order.

Full guardianship typically removes rights in these areas:

• Healthcare decisions
• Financial and property decisions
• Where to live
• Who to associate with
• Whether to marry or have children
• Daily life decisions like employment, education, and recreation

Some states offer limited guardianship, which restricts decision-making authority to specific areas such as finances or healthcare. This preserves more autonomy than full guardianship, but it still requires a court finding that the person is incapable of making decisions in those areas.

Guardianship is permanent unless the court reverses it. That process is difficult, expensive, and rarely successful.

Why Advocates Recommend Starting with SDM

Between 1.5 and 3 million adults in the U.S. are currently under guardianship. Research from the Administration for Community Living found that many of them were placed under guardianship unnecessarily: less restrictive alternatives were available, but families and courts didn't know to consider them.

Disability rights organizations now recommend trying supported decision-making first, before pursuing guardianship. The reasoning is straightforward: SDM allows your child to build decision-making skills with support, rather than losing the opportunity to develop those skills at all.

If SDM doesn't provide enough structure after a genuine effort, guardianship remains an option. But once guardianship is in place, reversing it is nearly impossible. Starting with the least restrictive option preserves your child's autonomy while still giving them the help they need.

When Guardianship May Still Be Necessary

Supported decision-making works when your child can participate in decisions, even with assistance. If your child cannot express preferences, cannot understand information even when it's explained in accessible ways, or cannot weigh options with support, guardianship may be the more appropriate path.

Some families also pursue guardianship when third parties refuse to recognize an SDM agreement. Banks, medical providers, and schools sometimes fall into this category. This is a practical reality in some states, though it's becoming less common as SDM laws gain traction.

Limited guardianship is a middle option. It grants decision-making authority in specific areas while allowing your child to retain rights in others. For example, you might have authority over finances while your child retains rights regarding healthcare, living situation, and relationships. If you're considering guardianship, ask your attorney whether limited guardianship is available in your state and whether it fits your situation.

A Third Option: Power of Attorney

Power of attorney is another tool to consider, particularly for young adults who can understand what they're signing. A power of attorney allows your child to appoint you or another trusted person to handle financial, property, or legal decisions on their behalf.

The key difference from guardianship: your child grants the authority voluntarily while they're still legally competent. It can be limited to specific tasks like managing a bank account or signing a lease, or it can be broad enough to cover all financial matters. Your child can revoke it at any time.

Power of attorney doesn't work for healthcare decisions in most states. For that, you'll need a healthcare proxy or an SDM agreement that covers medical decisions.

How to Start the Conversation with Your Attorney

If you're meeting with an attorney to discuss decision-making options, here's how to frame the conversation:

Start by asking about supported decision-making. Not every attorney is familiar with SDM, especially in states where it's newer. If your attorney dismisses it or says it's not recognized in your state, ask specifically: "Is there an SDM statute in this state, and if not, can we create a contractual agreement that functions the same way?"

Ask about limited guardianship if SDM doesn't fit. Many attorneys default to full guardianship because it's the path they know. Asking about limited guardianship signals that you're thinking about preserving rights where possible.

If your attorney recommends full guardianship, ask why. Specifically: what rights will your child lose, what decisions you'll be authorized to make, and why those restrictions are necessary given your child's actual abilities. A good attorney will walk you through this in detail. If the answer is "it's just what we do," consider getting a second opinion.

What the Decision Comes Down To

The decision at 18 is not binary. You're not choosing between full control and no support. You're choosing the level of structure that fits your child's current abilities, with the understanding that you can adjust later if needed.

Supported decision-making starts with the assumption that your child has capacity and builds support around that. Guardianship starts with the assumption that your child lacks capacity and removes rights accordingly. Both are legal tools. Both serve families. But the starting point matters.

If your child can participate in decisions with help, try SDM first. If it doesn't provide enough structure after a real effort, guardianship is still available. But you'll have given your child the chance to build skills, and you'll have preserved their autonomy for as long as it was workable.

This is careful planning, not a risk.
