Guardianship of a Disabled Adult Child in Westchester (SCPA 17-A)

If your son or daughter has an intellectual or developmental disability and is approaching (or has passed) their 18th birthday, you can ask the Westchester County Surrogate’s Court to appoint you as guardian of their person and/or property under SCPA Article 17-A. This is the track New York created specifically for parents and relatives of developmentally disabled adults. It is not the same as Article 81 of the Mental Hygiene Law, and — critically — it is filed in a different court. Article 17-A guardianship of a developmentally disabled person is heard in the Surrogate’s Court, while Article 81 guardianship of an incapacitated adult is heard in the Supreme Court. Choosing the right track and the right courthouse is the single most important decision in your case, and this guide walks Westchester families through it.

Why 18 Changes Everything

The day your child turns 18, the law treats them as a legal adult. No matter how significant their disability, you lose the automatic authority you had as a parent. You may no longer be able to sign consent forms, speak with doctors, manage benefits, or make financial decisions on their behalf. For a young adult with Down syndrome, autism, cerebral palsy, or another intellectual or developmental disability, that legal gap can be sudden and disruptive. Guardianship is the court process that restores your authority to act for and with your adult child — but only after a judge agrees it is appropriate.

To understand where 17-A fits, it helps to see the bigger picture. We cover the full landscape on our Guardianship Overview page.

SCPA Article 17-A vs. MHL Article 81: Two Different Tracks

New York has more than one guardianship statute, and they serve different populations. Confusing them is the most common — and costliest — mistake families make.

	SCPA Article 17-A	MHL Article 81
Who it’s for	Persons with an intellectual or developmental disability (often a child turning 18)	Adults who are incapacitated for any reason (stroke, dementia, brain injury, illness)
Court	Westchester County Surrogate’s Court	Supreme Court, Westchester County
Standard	More plenary — based on a certified diagnosis of intellectual/developmental disability	Least restrictive, needs-based; powers tailored to specific functional limitations
Proof	Certifications from qualified physician(s) / psychologist	Clear and convincing evidence of incapacity and likely harm

Because the statutes target different conditions, a developmentally disabled young adult is usually a 17-A case. An adult who became incapacitated later in life — say a parent with advancing dementia — is usually an Article 81 case. We explain that adult-incapacity track in detail on our Article 81 Guardianship page, and we cover minors under SCPA Article 17 on our Guardianship of Minors page.

The #1 accuracy point: Article 17-A guardianship of a developmentally disabled person is filed in the Surrogate’s Court in Westchester. Article 81 guardianship of an incapacitated adult is filed in the Supreme Court. Never confuse the two — they have separate petitions, separate judges, and separate procedures.

How an Article 17-A Case Works in Westchester

While every case is unique, an Article 17-A proceeding in Westchester County Surrogate’s Court generally follows these steps:

1. The petition. A parent, relative, or interested person files a verified petition asking the Surrogate’s Court to appoint a guardian of the person, of the property, or both.
2. Medical certifications. Article 17-A requires certifications from qualified professionals (a physician and/or licensed psychologist) confirming the intellectual or developmental disability and that guardianship is in the person’s best interest.
3. Notice and a guardian ad litem. The court ensures the disabled person and close family receive notice. The Surrogate may appoint a guardian ad litem to independently evaluate whether guardianship serves the person’s interests.
4. The hearing. The Surrogate reviews the certifications, any guardian ad litem report, and the family’s circumstances, then decides whether to grant the guardianship and to whom.
5. Standby and successor guardians. A major advantage of 17-A: parents can name standby and successor guardians so authority passes seamlessly if the primary guardian dies or can no longer serve.

We do not quote specific filing fees or courthouse street addresses here, because those should be confirmed directly with the Surrogate’s Court or your attorney before you file.

A Guardian’s Ongoing Duties

Being appointed is the beginning, not the end. A guardian holds a fiduciary duty to act in the disabled person’s best interest, to keep their funds separate and properly managed, and to make decisions that respect the person’s dignity and preferences wherever possible. The court expects accountability and may require reporting on the person’s well-being and finances.

For an adult Article 81 guardian, New York law sets out specific recurring obligations — for example, filing an initial report within 90 days, filing annual reports, and visiting the incapacitated person at least four times per year. Article 17-A has its own reporting expectations set by the Surrogate’s Court. Whichever track applies to your family, you should understand the responsibilities before you accept the role. Our Guardian Duties page breaks them down.

Consider Less Restrictive Alternatives First

New York courts strongly prefer the least restrictive intervention. Before pursuing full guardianship, a Westchester family should ask whether the young adult — perhaps with support — can use one of these tools instead:

• Durable Power of Attorney (General Obligations Law §5-1513) for financial matters
• Health Care Proxy for medical decisions
• Supplemental (Special) Needs Trust to hold assets without disqualifying the person from Medicaid or SSI
• Living Trust for asset management
• Supported Decision-Making, where the person keeps legal authority but designates trusted supporters to help them understand and communicate choices

These alternatives work best when the disabled adult can knowingly sign documents and appreciate their meaning. When the disability is more profound, guardianship may be the only realistic option. We compare each tool on our Alternatives to Guardianship page.

Frequently Asked Questions

Is Article 17-A guardianship filed in Surrogate’s Court or Supreme Court in Westchester?
SCPA Article 17-A guardianship of a developmentally disabled person is filed in the Westchester County Surrogate’s Court. Only adult Article 81 (Mental Hygiene Law) guardianship of an incapacitated person goes to the Supreme Court.

My child is still 17 but turns 18 soon — when should I file?
Many Westchester families file an Article 17-A petition as the child approaches 18 so the guardianship is in place when they become a legal adult. Speaking with counsel early helps you time the filing and gather the required medical certifications.

Can I name someone to take over if I can no longer serve?
Yes. A key benefit of Article 17-A is that parents can designate standby and successor guardians, giving the family long-term continuity of care.

Will guardianship take away all of my child’s rights?
Courts favor the least restrictive option that meets the person’s actual needs. Depending on the facts, alternatives like a Power of Attorney, Health Care Proxy, or Supported Decision-Making may preserve more of your child’s autonomy. An attorney can help you choose the right level of intervention.
