When a parent in Yonkers can no longer manage their finances, when an aging relative in New Rochelle is being financially exploited, or when a young adult with a developmental disability in White Plains is approaching their eighteenth birthday, families across Westchester County turn to the same question: who is legally authorized to make decisions, and how does New York let them step in?
Guardianship is the court process that answers that question. But the word “guardianship” covers several very different proceedings under New York law, each with its own statute, its own standard, and — critically — its own courthouse. Getting the right one matters. This Westchester-focused guide from Morgan Legal Group, led by attorney Russel Morgan, Esq., explains how these cases actually move through the courts that serve communities from the Sound Shore down to the Hudson, and how to decide whether you even need a guardianship at all.
The Two Guardianship Worlds in New York
New York does not have a single “guardianship law.” It has two largely separate systems, and confusing them is the most common — and most expensive — mistake families make.
| Situation | Governing law | Court that hears it (Westchester) | Standard |
|---|---|---|---|
| An adult who has lost capacity (dementia, stroke, brain injury, serious mental illness) | Mental Hygiene Law (MHL) Article 81 | Supreme Court, Westchester County | Incapacity proven by clear and convincing evidence |
| A minor child needing a guardian of person or property | SCPA Article 17 | Surrogate’s Court, Westchester County (may also be Supreme/Family Court) | Best interests of the child |
| An adult with an intellectual or developmental disability (since childhood) | SCPA Article 17-A | Surrogate’s Court, Westchester County | Plenary status determination |
If you take only one thing from this guide, take this: adult-incapacity guardianship under Article 81 is a Supreme Court case, not a Surrogate’s Court case. A petition for a stroke-disabled parent in Mount Vernon does not belong in Surrogate’s Court — it is filed in the Supreme Court, Westchester County. Surrogate’s Court in Westchester handles the SCPA Article 17 and 17-A matters described below, along with wills and estates.
For a broader orientation, see our guardianship overview.
Article 81: Guardianship for Adults Who Have Lost Capacity
The majority of guardianship cases we see for Westchester families involve adults who once managed their own affairs but no longer can. These are governed by MHL Article 81, and they are heard in the Supreme Court, Westchester County, whose courthouse sits in White Plains and serves residents from Peekskill and Cortlandt in the north to Yonkers and the river towns in the south.
The least restrictive alternative principle
Article 81 was deliberately designed to avoid sweeping people’s rights away wholesale. Its foundational rule, MHL §81.02, directs the court to impose only the powers that are actually necessary — the least restrictive alternative. A person who can still choose where to live but cannot manage a bank account should not lose both rights. The judge can appoint:
- a guardian of the person (for personal-needs decisions — medical care, residence, daily life), and/or
- a guardian of the property (for financial affairs — paying bills, managing accounts, protecting assets),
with each set of powers tailored to the documented need. Learn more about how these powers function on our Article 81 guardianship page.
What the proceeding looks like
An Article 81 case is genuinely adversarial in structure, even when the family is united, because the law protects the rights of the alleged incapacitated person (AIP). Key features include:
- The court evaluator. Under MHL §81.09, the Supreme Court appoints an independent court evaluator — often a Westchester-area attorney — to investigate the AIP’s actual condition, finances, and wishes, interview the people involved, and report back to the judge. This is not a rubber stamp; the evaluator’s report frequently shapes the outcome.
- The AIP’s right to counsel and a hearing. The AIP has the right to be represented by an attorney and to a hearing. The judge cannot appoint a guardian without finding incapacity by clear and convincing evidence and that a guardian is genuinely necessary.
- The clear-and-convincing standard. This is a demanding burden of proof — higher than the “preponderance” standard in ordinary civil cases — and it reflects how seriously New York treats the removal of an adult’s decision-making rights.
A typical uncontested Westchester Article 81 case moves from petition through court evaluator investigation to a hearing over a period of weeks to a few months; a contested one can take considerably longer. See contested guardianship for what happens when family members or the AIP disagree.
SCPA Article 17 and 17-A: Minors and Developmental Disability
The second guardianship world lives in Surrogate’s Court, Westchester County.
SCPA Article 17 governs guardianship of an infant (minor) — for example, when a child in Ossining inherits assets, receives a settlement, or needs a guardian after losing a parent. Article 17 guardianships of a minor may, depending on the matter, also be brought in Supreme or Family Court.
SCPA Article 17-A governs guardianship of an adult with an intellectual or developmental disability — conditions present since youth, such as autism, Down syndrome, or cerebral palsy. Westchester families with a developmentally disabled child commonly file these petitions as the child nears age eighteen, when the parents’ automatic authority ends.
It is important to understand the contrast in design. Article 17-A is a plenary status — historically a broader, more all-or-nothing grant of authority — whereas Article 81 is built around tailored, least-restrictive powers. For some young adults, Article 17-A is the right fit; for others, a more individualized Article 81 arrangement or a non-guardianship alternative better preserves autonomy. This is a decision worth talking through carefully rather than defaulting to whichever form is most familiar.
Alternatives: When You May Not Need Guardianship at All
A guardianship proceeding is a court case. It takes time, it is public to the extent court records are, and it imposes ongoing duties on the guardian. Before filing anything in White Plains, ask whether a less intrusive tool already does — or could do — the job. For many Westchester families, the answer is yes.
- Durable power of attorney (POA). A valid, durable POA signed while the person still has capacity lets a trusted agent handle finances without any court involvement. A properly executed POA can make an Article 81 property guardianship unnecessary.
- Health care proxy. This document names someone to make medical decisions if the person cannot. A valid proxy often eliminates the need for a personal-needs guardian.
- Living trust. Assets held in a revocable living trust can be managed by a successor trustee without guardianship of the property.
- Supported decision-making. A growing alternative — especially relevant for adults with developmental disabilities — in which the person keeps legal decision-making authority but designates trusted supporters to help them understand choices.
- Representative payee. For someone whose only relevant income is Social Security or similar benefits, a representative payee arrangement may handle that limited need without a full guardianship.
The catch with POAs and health care proxies is timing: they must be executed before capacity is lost. A family that plans ahead — while a parent in Scarsdale or Rye is still sharp — can often spare everyone an Article 81 proceeding entirely. Our alternatives to guardianship page goes deeper on each option.
A Guardian’s Ongoing Duties Are Real
Being appointed is the beginning, not the end. A Westchester guardian — whether under Article 81 or the SCPA — takes on continuing fiduciary obligations enforced by the court. These typically include filing an initial report or inventory after appointment and annual accounts to the court, keeping the protected person’s funds separate, acting only within the powers actually granted, and acting in the person’s best interests at all times. Failing to file accountings or mismanaging funds can lead to removal and personal liability. Our guardian duties page lays out these responsibilities in practical detail.
A note on cost: court filing fees are set by statute and by the court, and they should be confirmed with the court or your attorney rather than assumed. Contested cases and the cost of a guardian’s ongoing reporting are real factors families should weigh before filing.
Why the Westchester Geography Matters
Westchester is a large, varied county, and where a person lives and where their assets sit can affect venue and logistics. The county’s civil guardianship matters — the Article 81 Supreme Court cases and the Surrogate’s Court SCPA cases — are centered in White Plains, but the families behind them come from every corner: the dense urban communities of Yonkers, Mount Vernon, and New Rochelle; the Sound Shore villages of Larchmont, Mamaroneck, and Rye; the affluent suburbs of Scarsdale, Bronxville, and Chappaqua; and the northern towns of Peekskill, Cortlandt, Yorktown, and Bedford. Coordinating a court evaluator’s visit, gathering local medical records, and arranging hearings all run more smoothly when counsel knows how these courts operate day to day.
Frequently Asked Questions
Is Article 81 guardianship handled in Surrogate’s Court in Westchester?
No. Adult-incapacity guardianship under MHL Article 81 is brought in the Supreme Court, Westchester County — not Surrogate’s Court. Surrogate’s Court in Westchester handles SCPA Article 17 (minors) and Article 17-A (adults with intellectual or developmental disabilities), along with estates. Filing in the wrong court causes delay, so confirming the correct one at the outset matters.
What is a court evaluator, and will one be appointed in our case?
In an Article 81 case, the Supreme Court appoints an independent court evaluator under MHL §81.09 to investigate the alleged incapacitated person’s condition, finances, and wishes and report to the judge. In most Westchester Article 81 proceedings, yes — an evaluator is appointed, and their report carries real weight.
My mother lives in New Rochelle and has dementia. Can we avoid a guardianship?
Possibly, if she signed a durable power of attorney and a health care proxy while she still had capacity. Valid documents like these can make an Article 81 guardianship unnecessary. If no such documents exist and she can no longer execute them, an Article 81 petition in Supreme Court may be the appropriate path.
Our son with autism turns 18 soon. What kind of guardianship is that?
That is typically a SCPA Article 17-A guardianship, filed in Surrogate’s Court, Westchester County, for an adult with an intellectual or developmental disability. Because Article 17-A is a broader, plenary status, it is worth discussing whether it or a more tailored alternative best fits your son’s actual abilities.
How much does a guardianship cost in Westchester?
Court filing fees are set by statute and by the court and should be confirmed directly rather than assumed. Beyond filing fees, families should account for the court evaluator, attorney involvement, and the guardian’s ongoing duty to file accountings — all real, case-specific costs.
