Westchester County Guardianship: A 2026 Guide to Protecting the People You Love

When a family member in Westchester County can no longer make safe decisions about their own health, finances, or daily care, guardianship may be the legal tool that protects them. But “guardianship” is not one single process in New York. The correct procedure, and even the correct courthouse, depends entirely on who needs protection and why. A White Plains family caring for an aging parent with advancing dementia faces a different legal track than a Yonkers family planning for a child with intellectual disabilities who is about to turn eighteen.

At Morgan Legal Group, attorney Russel Morgan, Esq. helps Westchester families navigate these distinctions correctly the first time. This overview explains the three main guardianship tracks under New York law, which Westchester court hears each one, what a guardian actually has to do, and the less restrictive alternatives that courts here expect families to consider first.

The Three Guardianship Tracks in New York

The single most common mistake families and even some attorneys make is filing the wrong type of guardianship in the wrong Westchester court. Getting this right is the foundation of everything that follows.

Who needs protection	Governing law	Westchester court	Core idea
An adult who has become incapacitated (e.g., stroke, dementia, brain injury)	MHL Article 81	Supreme Court, Westchester County	Tailored, least-restrictive powers based on actual needs
A minor (under 18) needing a guardian of their person or property	SCPA Article 17	Westchester County Surrogate’s Court	Care and asset management for a child
A person with a developmental or intellectual disability (often a child turning 18)	SCPA Article 17-A	Westchester County Surrogate’s Court	Broader, more plenary guardianship for lifelong disability

Notice that adult Article 81 guardianship is filed in the Supreme Court — not the Surrogate’s Court. This is the number-one accuracy rule in New York guardianship practice. Surrogate’s Court in Westchester handles minors (Article 17) and the developmentally disabled (Article 17-A), but an incapacitated adult who once functioned independently is an Article 81 matter heard in Supreme Court, Westchester County.

Adult Guardianship: MHL Article 81 (Supreme Court)

Most guardianship calls our office receives from Westchester involve an adult who recently lost capacity. A parent in New Rochelle suffers a serious stroke. A spouse in Scarsdale is diagnosed with Alzheimer’s and can no longer manage the household finances. When that adult never signed a Power of Attorney or Health Care Proxy while healthy, the family often has no legal authority to act, and Article 81 of the Mental Hygiene Law becomes the path forward.

The Incapacity Standard

A New York court will not appoint a guardian simply because someone is old, eccentric, or makes choices the family dislikes. Under Article 81, the petitioner must prove by clear and convincing evidence that the person — called the Alleged Incapacitated Person (AIP) — cannot manage their property and/or personal needs and is likely to suffer harm because they cannot adequately appreciate the consequences of that inability. This is a deliberately high bar designed to protect personal liberty. Learn more on our dedicated Article 81 guardianship page.

How an Article 81 Case Moves Through Supreme Court

The process is more protective of the AIP’s rights than many families expect:

• Order to Show Cause and Verified Petition. The case is commenced in Supreme Court, Westchester County, by filing a Verified Petition along with a proposed Order to Show Cause that sets the hearing date.
• Appointment of a Court Evaluator. The court appoints a neutral Court Evaluator to independently investigate the AIP’s circumstances and report back. The court will often also appoint counsel to represent the AIP.
• The AIP’s rights. The Alleged Incapacitated Person has the right to be present and to a hearing. The court wants to hear from the person whose liberty is at stake whenever possible.
• Least restrictive intervention. If a guardian is appointed, the powers granted must be the least restrictive intervention tailored to the AIP’s actual needs. The judge can appoint a guardian of the person (for medical and personal-care decisions), a guardian of the property (for finances), or both — and nothing more than necessary.

This tailoring is what makes Article 81 powerful and humane: a Westchester resident who can still choose where to live but cannot manage a complex investment account may receive a property guardian only, preserving their independence everywhere else.

Guardianship of Minors: SCPA Article 17 (Surrogate’s Court)

When the person needing protection is a child under 18, the governing law is SCPA Article 17, and the case is filed in the Westchester County Surrogate’s Court. This arises when a minor inherits money or receives a settlement (a guardian of the property may be required), or when a child’s parents are deceased or unable to care for them (a guardian of the person). The Surrogate’s Court oversees the guardian to ensure the child’s assets and welfare are protected until adulthood. See our guardianship of minors page for details specific to families in Westchester.

Guardianship for Developmental Disabilities: SCPA Article 17-A

A distinct and very common Westchester situation involves a young person with an intellectual or developmental disability who is approaching their eighteenth birthday. Once that child becomes a legal adult, parents lose the automatic authority to make medical, educational, and financial decisions — even if the young person will never be able to make those decisions independently.

SCPA Article 17-A, also filed in the Westchester County Surrogate’s Court, addresses this. It is a different and generally more plenary (broader) form of guardianship than Article 81, designed for lifelong intellectual or developmental disability rather than a sudden loss of capacity in a previously independent adult. Families in communities from Mount Vernon to Peekskill frequently begin this planning during the child’s final year of high school so the guardianship is in place the moment it is legally needed.

A Guardian’s Ongoing Duties

Becoming a guardian is not a one-time court event — it is an ongoing fiduciary responsibility that the court continues to supervise. Under Article 81, a guardian’s core duties include:

• Initial report. File an initial report within 90 days of being appointed.
• Annual reports. File annual reports with the court accounting for finances and the welfare of the incapacitated person.
• Personal visits. Visit the incapacitated person at least four times per year — guardianship is about a real relationship, not just paperwork.
• Duration. Guardianship generally lasts for the person’s lifetime unless the court terminates it because capacity is restored or circumstances change.

These obligations are serious, and failing to meet them can lead to court intervention. Our guardian duties page walks through reporting, bonding, and accounting in practical terms.

Alternatives to Guardianship — Explore These First

New York courts, including those in Westchester, strongly prefer less restrictive alternatives to a full guardianship whenever they will adequately protect the person. Guardianship removes legal rights, so it should be a last resort. Before petitioning, every Westchester family should consider:

• Durable Power of Attorney (General Obligations Law §5-1513) — lets a competent adult name an agent to handle finances, avoiding a property guardianship entirely.
• Health Care Proxy — appoints someone to make medical decisions if the person cannot.
• Living Trust — allows a trustee to manage assets without court supervision.
• Supplemental (Special) Needs Trust — protects a disabled person’s eligibility for Medicaid and other benefits while providing for their needs.
• Supported Decision-Making — lets a person keep their legal rights while relying on trusted supporters to help them understand and communicate choices.

The catch is timing: most of these tools require the person to still have capacity to sign them. That is why proactive planning is so valuable — and why, once capacity is already lost, guardianship may be the only remaining option. Explore your options on our alternatives to guardianship page.

When Guardianship Is Contested

Not every Westchester guardianship is uncontested. Family members may disagree about whether guardianship is necessary, who should serve, or how the AIP’s assets should be handled. The Court Evaluator’s findings, the AIP’s own wishes, and competing petitions can all turn a routine filing into litigation. If you anticipate a dispute, see our contested guardianship page and seek counsel early.

Frequently Asked Questions

Which Westchester court handles adult guardianship?

Adult guardianship of an incapacitated person under MHL Article 81 is filed in the Supreme Court, Westchester County — not the Surrogate’s Court. The Surrogate’s Court handles guardianship of minors (SCPA Article 17) and of developmentally disabled individuals (SCPA Article 17-A).

What does the court have to prove before appointing a guardian for an adult?

Under Article 81, the court must find by clear and convincing evidence that the person cannot manage their property and/or personal needs and is likely to suffer harm because they cannot adequately appreciate the consequences. It is a high standard meant to protect personal freedom.

My adult child has a developmental disability and is turning 18. What do we file?

That is typically an SCPA Article 17-A guardianship, filed in the Westchester County Surrogate’s Court. It is broader than Article 81 and designed for lifelong intellectual or developmental disabilities. Many families begin this during the final year of high school.

Can we avoid guardianship altogether?

Often, yes — if planning happens while the person still has capacity. A durable Power of Attorney (GOL §5-1513), Health Care Proxy, living trust, special needs trust, or supported decision-making can frequently make guardianship unnecessary. Courts prefer these less restrictive alternatives.

How long does an Article 81 guardianship last?

Generally for the lifetime of the incapacitated person, unless the court terminates it because capacity is restored or the circumstances no longer require it. The guardian must file an initial report within 90 days, file annual reports, and visit the person at least four times per year.
