Maryland SDMA vs Guardianship When Your Child Turns 18
If you're choosing between a Supported Decision-Making Agreement and guardianship for your child approaching 18, here's the short answer: start with the SDMA. Maryland's 2022 Title 18 statute created a legally recognized framework that preserves your child's full civil rights while giving them a structured support network. Guardianship can transfer specified decision-making powers through a Circuit Court proceeding and should be reserved for situations where no combination of less restrictive alternatives provides adequate protection. Before granting a guardianship petition, Maryland law requires the court to find that no less restrictive form of intervention is available that is consistent with the person's welfare and safety.
What Each Option Actually Does
A Supported Decision-Making Agreement under Title 18 of the Estates and Trusts Article names one or more supporters who help an adult make their own decisions. The key word is help — the supporter cannot make decisions or sign documents on the person's behalf. The adult retains full legal capacity.
Guardianship, governed by Title 13 of the same article, transfers specific decision-making powers to a court-appointed guardian. A Guardian of the Person handles medical, housing, and daily care decisions. A Guardian of the Property manages finances. The court can appoint one type, the other, or both.
| Factor | SDMA (Title 18) | Guardianship (Title 13) |
|---|---|---|
| Who makes decisions | The adult, with support | The guardian |
| Court required | No | Yes — Circuit Court petition |
| Cost to establish | Free (notarization optional) | $165 self-represented or $185 represented, plus attorney fees ($3,000–$8,000 typical) |
| Time to establish | Same day | Typically 30–60 days after service to hearing; total time varies |
| Ongoing obligations | None | Annual reporting, court oversight |
| Effect on civil rights | None removed | Voting, marriage, contract rights may be restricted |
| Reversibility | Revoke anytime (oral, written, or clear intent) | Requires separate court petition to modify or terminate |
| Medical decision-making | No — pair with an Advance Directive | Yes, if Guardian of the Person |
| Financial authority | No — pair with a POA | Yes, if Guardian of the Property |
When an SDMA Is the Right Choice
An SDMA works when your child can make decisions with guidance but struggles with complex information, unfamiliar situations, or communication barriers. The 2025 Pughsley appellate ruling confirmed that SDMAs are valid court-recognized support mechanisms — the Appellate Court of Maryland reversed a lower court that had refused to let an individual exercise voting rights with SDMA support.
An SDMA is typically sufficient when your child:
- Understands the general concept of a decision and its consequences when information is presented clearly
- Can express preferences, even if through augmentative communication
- Benefits from someone explaining options, gathering information, or attending appointments alongside them
- Needs help with paperwork and logistics but not with the underlying choices
Maryland's Title 18 includes third-party liability protection — banks, hospitals, and service providers who rely on a properly executed SDMA are shielded from legal liability. This addresses the most common practical objection families encounter.
When Guardianship Is Necessary
Guardianship becomes the right tool when your child genuinely cannot participate in decision-making, even with support. The standard is clear and convincing evidence that the person lacks the capacity to make responsible decisions and that no less restrictive alternative exists.
Guardianship is typically appropriate when your child:
- Cannot understand the nature or consequences of decisions regardless of how information is presented
- Is at immediate risk of serious harm (financial exploitation, medical neglect, unsafe living conditions) that no other protective mechanism can address
- Has been assessed by two licensed professionals who certify the inability to make responsible decisions
The court requires certificates from two licensed healthcare professionals (at least one physician), with at least one examination within 21 days before filing. Starting October 1, 2026, the Maryland Judiciary is replacing the traditional Physician's Certificate with the new "Certificate — Guardianship Capacity Assessment" form.

Who This Is For
- Parents whose child turns 18 in the next 6–12 months and who need to decide between these two options
- Families told by a school, doctor, or bank that guardianship is "required" — who want to check whether that advice reflects current Maryland law
- Parents of adults already under guardianship who want to evaluate whether the 2022 SDMA law creates a viable path to restore some or all of their child's rights
Who This Is NOT For
- Families whose child has no cognitive disability — a standard Power of Attorney and Advance Directive are simpler tools
- Parents seeking guardianship over an elderly parent — different considerations apply (though the same statutes govern the process)
- Families outside Maryland — SDMA laws vary dramatically by state
The Middle Path Most Families Miss
The comparison above presents SDMA and guardianship as an either/or choice. In practice, most Maryland families benefit from a layered approach:
- SDMA for day-to-day support and decision-making assistance
- Power of Attorney (Title 17) for specific financial transactions that require signature authority
- Advance Directive (Health-General Article Title 5, Subtitle 6) for medical decision-making authority
- Limited guardianship only for domains where the other tools genuinely cannot provide adequate protection
This layered approach helps document for the Circuit Court that less restrictive alternatives were explored. If you later need to petition for limited guardianship over a specific domain (say, financial management), having an SDMA and POA already in place demonstrates that you've considered the least restrictive options first.
What Maryland's IEP Exception Changes
One factor that reduces urgency for many families: under Maryland Education Article § 8-412.1, educational decision-making rights do not automatically transfer to the student at 18. Unlike most states, Maryland parents retain IEP authority through graduation or exit, generally until the end of the school year in which the student turns 21 — unless the student has not been adjudged incompetent under state law and specific documented conditions apply, including parental unavailability or unknown status with the student's request, a year of nonparticipation after repeated school attempts, written rejection, specified prolonged illness or extraordinary circumstances with parental consent, or the student living outside the parental home without another public agency's care.
This means guardianship is never needed solely to maintain IEP participation. If a school administrator tells you otherwise, the statute citation above is the conversation-ender.
Cost and Time Comparison
The financial difference is substantial. An SDMA costs nothing beyond printing and witness signatures (notarization is optional). A guardianship petition in Maryland's Circuit Court starts with a $165 filing fee for a self-represented litigant or $185 when represented by an attorney, but attorney fees for an uncontested case typically run $3,000–$8,000. Contested cases — where the alleged disabled person or another family member objects — can exceed $15,000.
Beyond the initial cost, guardianship carries ongoing obligations. Guardians must file annual reports with the court. Failure to file can result in sanctions or removal. An SDMA has no reporting requirements and can be modified or revoked at any time.
Frequently Asked Questions
Can I have both an SDMA and guardianship at the same time?
Yes, but it's unusual. A limited guardianship might cover one specific domain (such as major financial decisions) while an SDMA covers everything else. The Pughsley ruling affirmed that courts can modify existing guardianship orders to allow SDMA-supported autonomy in certain areas.
Will banks and hospitals actually honor an SDMA?
Maryland's Title 18 explicitly protects third parties from liability when they rely on a valid SDMA. If a bank refuses, providing the statutory citation and a properly executed agreement resolves most disputes. The guide includes the specific language and procedure for handling institutional pushback.
What if my child's capacity changes over time?
An SDMA can be revoked and rewritten at any time. If your child's needs increase, you can add a POA, an Advance Directive, or petition for limited guardianship over specific domains. If their capacity improves — through skill-building, therapy, or experience — the SDMA naturally accommodates that growth without a court modification.
Does the SDMA give my child's supporter access to medical records?
No. An SDMA authorizes the supporter to help with decisions, not to access records independently. For medical records access, your child should sign a HIPAA authorization. An Advance Directive naming you as agent addresses medical decision-making. The Maryland Guardianship & Alternatives Guide covers how to layer these documents together.
How do I know if my child has "capacity" to sign an SDMA?
The capacity threshold for signing an SDMA is lower than most parents expect. Your child needs to understand what the agreement does — that they're choosing a supporter to help them with decisions — and sign voluntarily. There is no clinical assessment requirement. If your child can express that they want help with decisions and can identify who they trust to help, they likely have sufficient capacity.
What happens if a judge denies our guardianship petition?
If the evidence of incapacity is insufficient or the court finds that a less restrictive alternative is adequate, it may deny the petition. A denial does not necessarily mean the court found your child capable; it means the petition did not establish the required grounds. You'll want to have the SDMA, POA, and Advance Directive already executed so the transition is seamless.
The Maryland Adult Guardianship & Alternatives Guide walks through both pathways — SDMA execution and guardianship filing — so you're prepared regardless of which direction your family's assessment points.
