When a loved one on Long Island can no longer manage their own finances, health care, or daily safety, a guardianship may be the legal tool that keeps them protected. But guardianship in New York is not one process — it is several distinct procedures, each governed by a different statute and decided in a different court. Filing in the wrong court, or asking for more authority than the law allows, can delay relief for the very person you are trying to help.
At Morgan Legal Group, attorney Russel Morgan, Esq. and our team guide Nassau County and broader Long Island families through every track of guardianship — from emergency adult petitions in the Supreme Court to guardianship of a minor or a developmentally disabled child in the Surrogate’s Court. This page explains how guardianship works on Long Island, which court hears your matter, and the less-restrictive alternatives a court will expect you to consider first.

The Three Guardianship Tracks — and the Correct Long Island Court
The single most important accuracy point in New York guardianship is which court hears the case. The track depends on who needs protection.
| Who needs protection | Governing statute | Where it is filed on Long Island |
|---|---|---|
| An adult who has become incapacitated (illness, injury, dementia, stroke) | MHL Article 81 | Supreme Court, Nassau County (the Supreme Court — not Surrogate’s Court) |
| A minor (under 18) needing a guardian of person or property | SCPA Article 17 | Nassau County Surrogate’s Court |
| A developmentally or intellectually disabled person (often a child turning 18) | SCPA Article 17-A | Nassau County Surrogate’s Court |
This distinction is not a technicality. Adult Article 81 guardianship of an incapacitated person is heard in the Supreme Court, where the person resides — for Nassau residents, the Supreme Court in Mineola. Guardianship of minors and of developmentally disabled adults goes to the Surrogate’s Court. We see families lose weeks because a petition landed in the wrong courthouse. Getting this right at the outset is the foundation of an efficient case. Learn more on our guardianship overview.
Article 81 Adult Guardianship on Long Island
Most calls we receive from Massapequa, Garden City, Hempstead, Great Neck, and the rest of Nassau County involve an aging or suddenly incapacitated adult. MHL Article 81 is the governing framework, and it is built around a single principle: the least restrictive intervention.
The legal standard
A court may appoint a guardian only when it finds, by clear and convincing evidence, that the person (the “alleged incapacitated person,” or AIP):
- cannot manage their property and/or personal needs, and
- is likely to suffer harm because they cannot adequately appreciate the nature and consequences of that inability.
Both prongs must be met. A diagnosis alone is never enough.
How an Article 81 case proceeds
- Commencement. The case begins with an Order to Show Cause and a Verified Petition filed in the Supreme Court for the county where the AIP lives.
- Court Evaluator. The court appoints a neutral Court Evaluator — and often independent counsel for the AIP — to investigate and report on whether a guardian is truly needed.
- Rights of the AIP. The AIP has the right to be present, to attend the hearing, to retain counsel, and to contest the petition.
- Tailored powers. If guardianship is granted, the court awards only the specific powers the person actually needs — a personal-needs guardian, a property-management guardian, or both — never more than necessary.
Our Article 81 guardianship page walks through each stage in detail, and our contested guardianship page explains your options when family members disagree.
Guardianship of Minors and Disabled Adults (Surrogate’s Court)
Not every guardianship involves an incapacitated adult. Two important tracks run through the Nassau County Surrogate’s Court:
- SCPA Article 17 — Guardianship of a minor. When a child under 18 inherits assets, receives a settlement, or loses a parent, a guardian of the person and/or property may be appointed in Surrogate’s Court.
- SCPA Article 17-A — Guardianship of a developmentally or intellectually disabled person. This is the path many Long Island parents take as a child with a developmental disability approaches their 18th birthday. Article 17-A grants a broader, more plenary authority than Article 81 and uses a different standard. It is filed in the Surrogate’s Court, not the Supreme Court.
See our guardianship of minors page for the specifics of each.
A Guardian’s Ongoing Duties
Guardianship is not a one-time court order — it is an ongoing fiduciary responsibility the court actively supervises. Under Article 81, a guardian must:
- File an initial report within 90 days of appointment;
- File annual reports accounting for the person’s finances and well-being;
- Visit the incapacitated person at least four times per year; and
- Act at all times in the person’s best interest.
An Article 81 guardianship generally lasts for the person’s lifetime unless the court terminates it because the person has recovered capacity or circumstances change. Our guardian duties page details the reporting calendar and what the court expects.
Consider the Alternatives First
New York courts strongly prefer the least restrictive solution, and a well-prepared estate plan can often avoid guardianship entirely. Before petitioning, every Long Island family should ask whether these tools — many of which can be put in place while a loved one still has capacity — would suffice:
- Durable Power of Attorney (GOL §5-1513) — appoints a trusted agent to handle finances.
- Health Care Proxy — names someone to make medical decisions.
- Living Trust — manages assets without court involvement.
- Supplemental / Special Needs Trust — protects a disabled beneficiary’s eligibility for benefits.
- Supported Decision-Making — a less-restrictive alternative for individuals who need help but not a full guardian.
If a court sees that workable alternatives exist, it may decline to appoint a guardian. Visit our alternatives to guardianship page to see whether one fits your family.
Frequently Asked Questions
Is adult guardianship on Long Island filed in Surrogate’s Court?
No. Adult Article 81 guardianship of an incapacitated person is filed in the Supreme Court, Nassau County — the county where the person resides. Only guardianship of a minor (SCPA Article 17) or of a developmentally disabled person (SCPA Article 17-A) goes to the Nassau County Surrogate’s Court.
What does the court have to find before appointing a guardian for an adult?
Under Article 81, the court must find by clear and convincing evidence that the person cannot manage property and/or personal needs and is likely to suffer harm because they cannot appreciate the consequences of that inability.
Who is the Court Evaluator and do we have to pay for one?
The Court Evaluator is a neutral investigator the Supreme Court appoints to report on whether guardianship is warranted and what powers are appropriate. Fees are set and allocated by the court; we will review the likely cost structure with you, but we do not quote court fees on this page.
Can we avoid guardianship altogether?
Often, yes. A durable Power of Attorney (GOL §5-1513), Health Care Proxy, or trust executed while your loved one still has capacity can eliminate the need for a court proceeding. These should be explored first.
How long does a Long Island guardianship last?
An Article 81 guardianship generally continues for the person’s lifetime unless terminated by the court. The guardian must file an initial report within 90 days, file annual reports, and visit the person at least four times a year.
