When a family member on Long Island can no longer manage their own finances, health care, or daily affairs — and no advance planning is in place — guardianship is often the legal tool that protects them. But “guardianship” in New York is not one thing. It is several distinct legal tracks, each governed by a different statute, each heard in a different court, and each carrying its own standard of proof. Choosing the wrong track or filing in the wrong court costs families time, money, and stress at an already difficult moment.
This overview, prepared by Morgan Legal Group and attorney Russel Morgan, Esq., explains how guardianship works for Nassau County and Long Island residents in 2026 — the difference between adult guardianship under Mental Hygiene Law (MHL) Article 81, guardianship of a minor under SCPA Article 17, and guardianship of a developmentally disabled person under SCPA Article 17-A. We also walk through the alternatives that the courts expect families to consider first.
The Three Guardianship Tracks (and Where Each Is Filed)
The single most important thing to get right is which court hears your case. This is where many families and even some attorneys stumble. Adult guardianship is not a Surrogate’s Court matter.
| Track | Governing Statute | Who It Covers | Court (Long Island / Nassau) |
|---|---|---|---|
| Adult guardianship of an incapacitated person | MHL Article 81 | An adult who cannot manage property and/or personal needs | Supreme Court, Nassau County (the Supreme Court) |
| Guardianship of a minor’s person or property | SCPA Article 17 | A child under 18 | Nassau County Surrogate’s Court |
| Guardianship of a developmentally/intellectually disabled person | SCPA Article 17-A | Often a child turning 18 with a lifelong disability | Nassau County Surrogate’s Court |
For Long Island families, that means an Article 81 petition for an aging parent in Garden City, Hempstead, Long Beach, or Glen Cove is brought in the Supreme Court of the county where the alleged incapacitated person resides — Nassau County for Nassau residents. A petition for a minor child, or for a 17-A guardianship as a disabled child approaches adulthood, goes to Nassau County Surrogate’s Court.

Article 81: Adult Guardianship of an Incapacitated Person
Most Long Island guardianship matters involving an adult fall under MHL Article 81. This is the framework used when an older adult develops dementia, suffers a stroke, or otherwise loses the ability to handle their own affairs — and did not sign a power of attorney or health care proxy while they had capacity.
The Legal Standard: Clear and Convincing Evidence
A court does not appoint a guardian simply because a person is old, ill, or making decisions the family dislikes. Under Article 81, the petitioner must prove by clear and convincing evidence that:
- The person (the Alleged Incapacitated Person, or AIP) is likely to suffer harm because they cannot manage property and/or meet personal needs; and
- The person cannot adequately understand and appreciate the nature and consequences of that inability.
“Clear and convincing” is a demanding standard — higher than the ordinary “preponderance” used in most civil cases. This protects the AIP’s autonomy. New York law treats the removal of a person’s right to control their own life and money as a serious step, not a formality.
How an Article 81 Case Proceeds
An Article 81 proceeding is commenced by an Order to Show Cause together with a Verified Petition. After filing in Nassau County Supreme Court, the process typically unfolds as follows:
- Court Evaluator appointed. The court appoints a neutral Court Evaluator — effectively the court’s investigator — to meet the AIP, review the allegations, and report back on whether a guardian is truly needed and what powers are appropriate. In many cases the court also appoints counsel for the AIP.
- The AIP’s rights are protected. The AIP has the right to be present at the hearing, to be represented, to present evidence, and to cross-examine witnesses. The court generally holds the hearing in a manner that allows the AIP to participate.
- The hearing. The court hears testimony and reviews the Court Evaluator’s report before deciding whether the clear-and-convincing standard is met.
Least Restrictive Intervention
A defining principle of Article 81 is that any powers the court grants must be the least restrictive intervention necessary, tailored to the AIP’s actual functional limitations. The court can appoint a guardian of the person (for personal-needs decisions such as health care and living arrangements), a guardian of the property (for financial management), or both — and it grants only the specific powers the evidence supports. A person who can still handle some affairs keeps those rights. This page on contested guardianship explains what happens when family members disagree about whether a guardian is needed or who it should be.
Ongoing Duties of an Article 81 Guardian
Appointment is the beginning, not the end. An Article 81 guardian on Long Island has continuing obligations to the court:
- File an initial report within 90 days of appointment.
- File annual reports thereafter accounting for the incapacitated person’s finances and well-being.
- Visit the incapacitated person at least four times per year.
- Act always in the incapacitated person’s best interests and within the powers the court granted.
The guardianship generally lasts for the person’s lifetime unless the court terminates or modifies it — for example, if the person recovers capacity. Our guardian duties page covers these responsibilities in detail, including reporting and recordkeeping.
SCPA Article 17: Guardianship of a Minor
When the issue is a child under 18 — for example, a Long Island child who has inherited money, received a settlement, or whose parents are unable to care for them — the governing law is SCPA Article 17, and the case is filed in Nassau County Surrogate’s Court. A Surrogate’s Court guardian of a minor may be appointed over the child’s person, the child’s property, or both. This track ends, by its nature, when the minor reaches the age of majority.
SCPA Article 17-A: Guardianship of a Developmentally Disabled Person
SCPA Article 17-A addresses a different situation: a person with an intellectual or developmental disability — most commonly a young adult who is turning 18 and will need lifelong support. These petitions are also filed in Nassau County Surrogate’s Court.
It is important to understand that Article 17-A applies a different and more plenary standard than Article 81. Where Article 81 is carefully tailored and “least restrictive,” a 17-A guardianship is broader. For that reason, many advocates and courts encourage families to consider whether the more individualized Article 81 framework, or a less restrictive alternative, would better serve a particular young adult. This is a decision Long Island families should discuss with counsel, because the right path depends on the individual’s actual abilities.
Alternatives to Guardianship — Explore These First
New York courts prefer alternatives to guardianship whenever they can adequately protect the person. Guardianship removes legal rights; the alternatives below preserve them. Before filing, every Long Island family should ask whether one of these tools — ideally put in place before a crisis — would do the job:
- Durable Power of Attorney under General Obligations Law (GOL) §5-1513 — lets a trusted agent manage finances without court involvement.
- Health Care Proxy — appoints someone to make medical decisions if the person cannot.
- Living Trust — allows a successor trustee to manage assets seamlessly.
- Supplemental / Special Needs Trust — protects assets and preserves benefit eligibility for a person with disabilities.
- Supported Decision-Making — a less restrictive arrangement in which the person keeps legal authority but receives help from trusted supporters.
A signed power of attorney and health care proxy can often make an Article 81 proceeding unnecessary altogether. See our alternatives to guardianship page for a fuller comparison.
Why the Court Matters So Much on Long Island
We return to the point because it is the one families get wrong most often: an adult Article 81 guardianship for a Nassau County resident is heard in the Supreme Court — not the Surrogate’s Court. Filing in the wrong court delays the case and the protection your loved one needs. By contrast, minor (Article 17) and disabled-person (17-A) guardianships belong in Nassau County Surrogate’s Court. Matching the track to the court at the outset is the foundation of a smooth proceeding.
We do not quote specific filing fees or court addresses here because those should always be confirmed with the court or your attorney; they can change and vary by filing.
Frequently Asked Questions
Is adult guardianship on Long Island filed in Surrogate’s Court?
No. Adult guardianship of an incapacitated person under MHL Article 81 is filed in the Supreme Court of the county where the person resides — Supreme Court, Nassau County for Nassau residents. Surrogate’s Court handles guardianship of minors (SCPA Article 17) and of developmentally disabled persons (SCPA Article 17-A), not adult Article 81 cases.
What does the court require to appoint an Article 81 guardian?
The petitioner must prove by clear and convincing evidence that the person is likely to suffer harm because they cannot manage their property and/or personal needs and cannot adequately appreciate the consequences of that inability. The court appoints a Court Evaluator to investigate, and the alleged incapacitated person has the right to be present, to counsel, and to a hearing.
How long does an Article 81 guardianship last, and what are the guardian’s duties?
It generally lasts for the person’s lifetime unless the court terminates or modifies it. The guardian must file an initial report within 90 days, file annual reports, and visit the incapacitated person at least four times per year, always acting within the powers the court granted.
Can we avoid guardianship entirely?
Often, yes. A durable Power of Attorney (GOL §5-1513), a Health Care Proxy, a living trust, a special needs trust, or a Supported Decision-Making arrangement can make guardianship unnecessary. Courts prefer these less restrictive options, which is why advance planning matters so much.
My disabled child is turning 18. Which track applies?
Likely SCPA Article 17-A in Nassau County Surrogate’s Court, though families should weigh whether the more tailored Article 81 framework or a less restrictive alternative is a better fit for that individual. An attorney can help you compare the standards.
