When a parent in Garden City begins to forget how to pay the mortgage, or a spouse in Massapequa suffers a stroke that leaves them unable to make medical and financial decisions, families on Long Island face a frightening question: who now has the legal authority to act? In New York, the answer for an adult who can no longer manage their own affairs is often a guardianship under Article 81 of the Mental Hygiene Law (MHL).
This page explains how adult Article 81 guardianship works specifically for Nassau County residents — including the correct court, the role of the court evaluator, the powers a guardian can hold, and the ongoing duties the court will hold you to. It also explains the alternatives that may let your family avoid a guardianship entirely. At Morgan Legal Group, attorney Russel Morgan, Esq. and our team guide Long Island families through every step. For an overview of all guardianship types, start with our guardianship overview.
The single most important point: which court hears your case
Long Island families are constantly confused about where a guardianship is filed, and getting it wrong costs time and money. The court depends entirely on who needs the guardian and why.
| Who needs protection | Governing law | Where it is filed (Nassau County) |
|---|---|---|
| An adult who has become incapacitated (stroke, dementia, brain injury) | MHL Article 81 | Supreme Court, Nassau County |
| A minor child’s 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 |
The key takeaway: an adult Article 81 guardianship is brought in the Supreme Court of Nassau County — not the Surrogate’s Court. The Surrogate’s Court in Mineola handles guardianships of minors and of the developmentally disabled. If you are seeking authority over an aging parent or an injured adult, your petition belongs in Supreme Court. Confusing these two tracks is the most common — and most avoidable — mistake we see. Learn more about the youth tracks on our guardianship of minors page.
What “incapacity” means under Article 81
New York deliberately set a high bar. A judge in Nassau County Supreme Court cannot appoint a guardian simply because a person is old, eccentric, or making choices the family dislikes. Under MHL Article 81, the petitioner must prove by clear and convincing evidence that the person — called the Alleged Incapacitated Person (AIP) — meets a two-part test:
- The person is likely to suffer harm because they cannot adequately understand and appreciate the nature and consequences of their inability to manage their property and/or personal needs; and
- The person cannot manage their property and/or personal needs.
This functional, evidence-based standard is intentionally demanding. It protects Long Islanders from having their independence stripped away without genuine cause, and it forces the court to grant only what is truly necessary.
How an Article 81 case proceeds in Nassau County
An Article 81 proceeding is more involved than many families expect. It is a real lawsuit, and the AIP has substantial due-process rights throughout.
1. The Order to Show Cause and Verified Petition
The case begins when the petitioner — often an adult child, spouse, or sibling — files an Order to Show Cause together with a Verified Petition in Nassau County Supreme Court. The petition must describe in detail the AIP’s condition, finances, available support, and the specific powers being requested.
2. Appointment of a Court Evaluator
This is the heart of an Article 81 case. The court appoints an independent Court Evaluator — typically an experienced attorney — to investigate and report back to the judge. The evaluator meets with the AIP, reviews records, interviews family members and caregivers, and explains the proceeding to the AIP. In many cases the court also appoints counsel to represent the AIP directly. The evaluator’s report often determines the outcome.
3. The AIP’s rights
The AIP has the right to be present at the hearing, the right to a jury trial in appropriate cases, the right to counsel, and the right to present evidence and cross-examine witnesses. The hearing is usually held in the courthouse in Mineola, though courts can accommodate a frail AIP, including hearing testimony at a hospital or nursing facility on Long Island when necessary.
4. The hearing and decision
At the hearing the judge decides whether the clear-and-convincing standard is met and, if so, exactly which powers to grant. If a guardianship is contested by the AIP or another family member, the stakes and complexity rise sharply — see our contested guardianship page.
“Least restrictive intervention”: tailored powers, not a blank check
A defining feature of Article 81 is that the court must impose the least restrictive intervention consistent with the AIP’s needs. Rather than declaring someone globally “incompetent,” the judge grants only the specific powers the evidence supports. The court may appoint:
- A guardian of the property (to manage finances, pay bills, handle real estate and benefits), and/or
- A guardian of the personal needs (to make decisions about medical care, residence, and daily life).
A single person may hold both roles, or the court may split them. If your father can still choose where he lives but can no longer handle his investment accounts, the court can grant property powers while leaving his personal autonomy intact. This tailoring is one reason Article 81 is considered more protective of individual rights than the broader Article 17-A standard used in Surrogate’s Court.
The duties of an Article 81 guardian
Being appointed is the beginning, not the end. A Nassau County guardian is a fiduciary supervised by the Supreme Court, and the reporting obligations are strict. Our guardian duties page covers these in depth, but the core requirements include:
- Initial report: file an inventory and initial report within 90 days of appointment.
- Annual reports: file an annual accounting of all financial activity and decisions every year for the court’s review.
- Personal visits: visit the incapacitated person at least four times per year.
- Bond and examination: post any bond the court requires, and submit to examination of the annual reports by a court examiner.
- Stay within the order: exercise only the powers the judge actually granted.
A guardianship under Article 81 generally lasts for the life of the incapacitated person unless the court terminates or modifies it — for example, if the person recovers capacity or passes away.
Alternatives Long Island families should weigh first
New York courts strongly prefer that families use less intrusive tools when they will work, and a judge may decline a guardianship if adequate alternatives already exist. Before petitioning, every Nassau County family should consider whether the person — while still capable — can or did put these in place:
- Durable Power of Attorney (GOL §5-1513) — appoints an agent to handle finances without court involvement.
- Health Care Proxy — names someone to make medical decisions.
- Living (Revocable) Trust — manages assets through a named trustee.
- Supplemental / Special Needs Trust — preserves means-tested benefits for a disabled person.
- Supported Decision-Making — assistance that lets a person keep legal decision-making authority.
The catch: most of these require capacity to execute. Once a person can no longer understand the documents, the window closes, and Article 81 may be the only path left. That is why we urge families to plan early. Explore options on our alternatives to guardianship page.

Frequently Asked Questions
Is an adult Article 81 guardianship filed in Surrogate’s Court in Nassau County?
No. Adult guardianship of an incapacitated person under MHL Article 81 is filed in the Supreme Court of Nassau County. The Nassau County Surrogate’s Court handles guardianships of minors (SCPA Article 17) and of developmentally disabled persons (SCPA Article 17-A), which are different proceedings.
How long does an Article 81 guardianship take?
Timing varies with the AIP’s condition, whether the case is contested, and the court evaluator’s schedule. An uncontested matter may resolve in a few months, while a contested case in Nassau County Supreme Court can take significantly longer. We cannot promise a specific timeline.
Can my family avoid guardianship altogether?
Often, yes — if planning is done while the person still has capacity. A durable Power of Attorney under GOL §5-1513, a Health Care Proxy, and a trust can frequently make a guardianship unnecessary. Once capacity is lost, those options usually disappear and Article 81 becomes the route.
What does the court evaluator do?
The court evaluator is an independent investigator appointed by the judge to meet the AIP, review the facts, and report to the court on whether a guardian is needed and what powers are appropriate. Their findings carry significant weight in the judge’s decision.
What ongoing duties will I have as a guardian?
You must file an initial report within 90 days, file annual accountings, visit the incapacitated person at least four times per year, post any required bond, and act only within the powers the court granted.
