Guardianship for an Autistic Adult in Connecticut

The First Surprise: It's Probably Not "Guardianship"

Most families searching for guardianship for their autistic adult child in Connecticut discover a distinction that doesn't exist in most other states. Connecticut reserves the term "guardianship" exclusively for adults with intellectual disabilities — a documented IQ of 69 or below with adaptive deficits originating before age eighteen, under C.G.S. § 45a-670.

Many autistic adults have an IQ at or above 70. For them, Connecticut's mechanism is conservatorship under C.G.S. § 45a-648, which covers adults with cognitive, developmental, or psychiatric impairments who don't meet the intellectual disability definition.

The practical difference matters. Guardianship uses a free DDS evaluation; conservatorship requires a private physician's exam. Guardianship uses Form PC-700; conservatorship uses Form PC-300. Using the wrong track can delay the process while the filing is corrected.

When Autistic Adults Qualify for Guardianship

Some autistic adults do meet the intellectual disability threshold. If your child has both an autism diagnosis and a documented IQ of 69 or below with concurrent adaptive deficits, the guardianship track under C.G.S. § 45a-670 applies. The probate court will order a Department of Developmental Services (DDS) assessment team evaluation (Form PC-770A), which is conducted at no cost to the family.

DDS eligibility and guardianship eligibility are closely linked but not identical. Your child may receive DDS case management services without meeting the guardianship IQ threshold, or may meet the threshold without being enrolled in DDS programs. The probate court's evaluation is the determining factor.

Conservatorship for Autistic Adults with IQ 70+

For autistic adults with an IQ of 70 or above, conservatorship is the court-ordered option. You'll file Form PC-300 (involuntary) with the local probate court, along with a physician's evaluation (Form PC-370) from a Connecticut-licensed doctor who has examined the individual within 45 days prior to the hearing.

The court can appoint a conservator of the person (personal welfare, medical decisions, housing), a conservator of the estate (financial management), or both. Connecticut law requires the court to favor limited orders, granting authority only in specific domains where incapacity has been proven.

This is especially important for autistic adults who function independently in many areas but struggle with specific tasks. Your child might manage their daily routine, social relationships, and personal hygiene perfectly well but need help navigating complex financial decisions, medical consent processes, or benefits paperwork. A limited conservatorship addresses the gaps without removing autonomy across the board.

Court-Free Alternatives That May Be Enough

Many autistic adults — including those with significant support needs — have the capacity to execute legal documents with appropriate accommodations. Before pursuing court involvement, evaluate whether your child can understand and sign:

A durable power of attorney under C.G.S. § 1-350 for financial management. Your child must understand the nature of the document and the scope of the authority being delegated. Plain-language explanations, visual supports, and extra processing time can help the young adult understand those points.

A health care representative designation under C.G.S. § 19a-576 for medical decisions. This stays dormant until a physician certifies incapacity, so your child retains full medical autonomy during routine care.

A supported decision making agreement through Disability Rights Connecticut's free SDM Clinic. The young adult keeps all legal authority while choosing a support network to help with decisions.

These tools can be layered: POA covers finances, health care representative covers medical crises, SDM covers day-to-day support, and HIPAA/FERPA releases cover information access. If all the gaps are filled, court involvement isn't necessary.

The Capacity Assessment Question

The dividing line between "can execute documents" and "needs court involvement" isn't always obvious for autistic adults. Capacity exists on a spectrum and can vary by domain and by day. Your child might have the capacity to choose a doctor but not to evaluate a complex financial contract.

Connecticut probate courts evaluate capacity domain by domain. The question isn't "is this person competent?" — it's "in which specific areas does this person lack the ability to make informed decisions, even with support?"

If you're uncertain, consider scheduling a capacity assessment with a psychologist or neuropsychologist familiar with autism. This evaluation can guide your decision before you invest time and money in a petition that may be unnecessary — or before you rely on informal documents that may be challenged later.

What Families Should Know About the Hearing

Whether you file for guardianship or conservatorship, the probate court appoints an independent attorney to represent your adult child. The attorney advocates for your child's expressed wishes — not yours. If your child doesn't want a conservator, the attorney will argue against the petition even if you believe it's necessary.

The court applies a "clear and convincing evidence" standard. You'll need to demonstrate both that your child cannot manage specific aspects of their life and that less restrictive alternatives have been considered and are insufficient.

For autistic adults who can communicate their preferences (including through AAC devices, sign language, or written communication), the court takes those expressed preferences seriously. A young adult who says "I want help with money but I pick my own friends" gives the judge strong grounds to limit the conservatorship's scope.

Finding the Right Path

The right approach depends on your child's specific profile — not their diagnosis label. Two autistic adults can have very different support needs, and Connecticut law is designed to match the level of intervention to the level of need.
