When a loved one in Westchester County can no longer manage their own affairs — a parent in White Plains slipping into dementia, an adult child in Yonkers with a developmental disability, or a young person in Mount Vernon who has inherited property — families need clear answers fast. Guardianship is the legal tool that lets a trusted person make decisions on someone else’s behalf, but New York law routes different situations through different courts, under different statutes, with different standards of proof.

Getting that routing right is the single most important step. At Morgan Legal Group, attorney Russel Morgan, Esq. helps Westchester families choose the correct track, weigh less-restrictive alternatives first, and move through the process with confidence.

Which Court Hears Your Case in Westchester?

This is the number-one accuracy rule in New York guardianship, and it trips up many families. The court depends entirely on who the guardianship is for.

Situation Governing Law Where It Is Filed in Westchester
Adult who has become incapacitated (e.g., dementia, stroke, brain injury) MHL Article 81 Supreme Court, Westchester County (the Supreme Court)
Minor child’s person or property SCPA Article 17 Westchester County Surrogate’s Court
Developmentally or intellectually disabled person (often a child turning 18) SCPA Article 17-A Westchester County Surrogate’s Court

A common mistake is assuming every guardianship goes to the Surrogate’s Court. It does not. An adult Article 81 guardianship is heard in the Supreme Court of Westchester County, never the Surrogate’s Court. Learn more on our guardianship overview page.

Adult Guardianship: MHL Article 81 in the Supreme Court

Most Westchester guardianship matters involve an adult — the Alleged Incapacitated Person (AIP) — who can no longer safely handle their finances, health care, or daily life. These cases proceed under Mental Hygiene Law Article 81 in the Supreme Court, Westchester County, in the county where the AIP resides.

The Incapacity Standard

New York deliberately sets a demanding bar. The court must find, by clear and convincing evidence, that the person:

This protects individual liberty: a person is not declared incapacitated merely because they are elderly, eccentric, or making choices their family dislikes.

How an Article 81 Case Works

  1. Filing. The case begins with an Order to Show Cause and a Verified Petition describing the AIP’s condition and the powers requested.
  2. Court Evaluator. The Supreme Court appoints a neutral Court Evaluator to investigate and report; it often also appoints counsel for the AIP.
  3. Hearing. The AIP has the right to be present and to a hearing. A judge — not the petitioner — decides the outcome.
  4. Least Restrictive Powers. If guardianship is granted, the court tailors the powers to the AIP’s actual needs. A judge may appoint a personal-needs guardian, a property-management guardian, or both — and only over the specific tasks the person genuinely cannot handle.

Guardianship of Minors and Disabled Persons: SCPA in Surrogate’s Court

Not every case belongs in Supreme Court. Two important tracks run through the Westchester County Surrogate’s Court:

What a Guardian Actually Has to Do

Becoming a guardian is an ongoing legal responsibility, not a one-time order. Under Article 81, an appointed guardian must:

Article 81 guardianship generally lasts for the person’s lifetime unless the court terminates or modifies it. See our full breakdown of guardian duties before you petition.

Consider Alternatives First — Courts Prefer Them

New York courts treat guardianship as a last resort. If your loved one still has capacity to plan, simpler tools may avoid a court case entirely. Westchester families should explore:

Even mid-case, the court evaluates whether these less-restrictive options meet the person’s needs. Our alternatives to guardianship page explains each in plain language. The earlier a Westchester family plans — ideally before a crisis — the more options remain available.

Frequently Asked Questions

Where do I file an adult guardianship in Westchester County?
An adult Article 81 guardianship is filed in Supreme Court, Westchester County, where the alleged incapacitated person resides — not in the Surrogate’s Court.

My adult son has a developmental disability and is turning 18. Which court?
That is typically an SCPA Article 17-A matter, filed in the Westchester County Surrogate’s Court, under a different standard than Article 81.

What does the court have to prove before granting Article 81 guardianship?
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 appreciate the consequences. The powers granted must be the least restrictive option.

Can we avoid guardianship altogether?
Often, yes — through a durable Power of Attorney, Health Care Proxy, a trust, or Supported Decision-Making, if the person still has capacity to sign. Courts favor these alternatives.

How long does an Article 81 guardianship last?
Generally for the person’s lifetime, unless the Supreme Court terminates or modifies it. The guardian must file an initial 90-day report, then annual reports.
