Maryland Down Syndrome Guardianship Options When Your Child Turns 18

What Changes at 18 for a Young Adult with Down Syndrome

On their 18th birthday, your child becomes a legal adult with a presumption of full decision-making capacity — regardless of their disability. You lose the automatic right to access medical records, direct healthcare decisions, and manage finances. This is true even if your child has significant cognitive challenges.

What does not change in Maryland: your educational decision-making rights. Under Maryland Education Article § 8-412.1, parents continue to hold IEP decision-making authority until the student exits school, unless a specific, documented transfer condition applies. This is a major state-specific exception to the federal norm — you do not need guardianship to stay involved in your child's education after they turn 18.

The Range of Options

Down syndrome encompasses a wide spectrum of cognitive ability. Some young adults with Down syndrome manage daily decisions with minimal support. Others need substantial assistance with medical, financial, or personal decisions. The right legal framework depends on where your child falls on that spectrum — and it does not have to be all or nothing.

Supported Decision-Making Agreement

Maryland's 2022 Supported Decision-Making Act (Estates and Trusts §§ 18-101 to 18-109) created a formal framework for exactly this situation. Your child names you (or other trusted people) as supporters who help gather information, evaluate options, and communicate decisions. Your child retains all legal rights and makes the final call.

For many families of young adults with Down syndrome, an SDMA is sufficient. The individual participates in decisions with structured support rather than having decisions made for them. The Appellate Court's 2025 Pughsley decision reinforced that SDMAs are valid court-recognized supports — even for individuals previously under guardianship.

Advance Health Care Directive + Financial POA

If your child can understand and sign legal documents, this combination covers the two biggest concerns: medical decisions and financial management. The advance directive designates a healthcare agent who can step in when the attending physician and a second independent physician certify incapacity; if the patient is unconscious, a second physician's certification is not required. The financial power of attorney grants an agent authority over banking, property, and financial transactions.

Under Maryland law, a written POA is presumed durable — the agent's authority persists even if your child later becomes incapacitated. Combined with an SDMA, this creates comprehensive coverage without any court involvement.

Limited Guardianship

If your child cannot understand the purpose and scope of a POA or advance directive, the non-court options may not be viable. A limited guardianship under Estates and Trusts § 13-708 lets the court grant authority over specific domains — medical decisions, for example — while preserving rights in areas where your child can manage independently.

Full Guardianship

Full guardianship of the person, the property, or both is the most restrictive option. The court strips nearly all decision-making rights from the individual. For young adults with Down syndrome, this should be a last resort — and Maryland law requires the court to find that no less restrictive alternative is adequate before granting it.

The Timeline That Matters

Start the evaluation process eight months before your child's 18th birthday. If you are going the non-court route (SDMA, POA, advance directive), the documents need to be in place before the birthday so there is no gap in legal authority. If you are pursuing guardianship, the hearing is typically scheduled 30 to 60 days after service, so beginning at 17 gives you a workable buffer.

Coordinate with your child's IEP team on transition planning at 14, and begin the DDA application process at the same time. The Governor's Transitioning Youth Initiative (GTYI) provides dedicated DDA funding for students exiting school — but the application window is strict.

Protecting SSI Benefits

If your child receives SSI, the age-18 redetermination is a separate process from any guardianship or legal planning. The SSA re-evaluates eligibility using adult disability criteria. You may need to become a representative payee to manage SSI payments — the SSA does not recognize guardianship or POA as granting automatic authority over federal benefits.

Keep the $2,000 SSI resource limit in mind when structuring financial protections. An ABLE account excludes up to $100,000 from this limit.

Making the Choice

The decision is not "guardianship or nothing." It is a continuum, and the right answer for your family depends on your child's specific abilities, needs, and goals. Most families of young adults with Down syndrome find that some combination of non-court tools — SDMA, advance directive, financial POA, representative payee — provides adequate protection while preserving the autonomy your child deserves.
