Not every guardianship proceeding is friendly. When relatives disagree about who should manage an aging parent’s finances, when one sibling believes another is overreaching, or when the person at the center of the case objects to losing their independence, a guardianship turns into a contested case. On Long Island, these disputes play out in Supreme Court, Nassau County under New York Mental Hygiene Law (MHL) Article 81 — the statute that governs guardianship of an incapacitated adult.
Morgan Legal Group, led by attorney Russel Morgan, Esq., represents families on both sides of these disputes: petitioners seeking to protect a vulnerable loved one in Garden City, Hempstead, Great Neck, or Long Beach, and respondents defending against an unwarranted or overreaching petition. This page explains how a contested guardianship works, what the court looks for, and how to position your case for success.
What Makes a Guardianship “Contested”?
A guardianship becomes contested when someone formally opposes the petition. That opposition can come from several directions:
- The alleged incapacitated person (AIP) objects, insisting they can still manage their own affairs.
- A competing family member files a cross-petition asking to be appointed instead of the original petitioner.
- An interested party disputes whether incapacity exists at all, or argues the requested powers are too broad.
- An existing agent under a power of attorney or health care proxy argues that the guardianship is unnecessary because less restrictive tools are already in place.
Under Article 81, the court cannot simply rubber-stamp a petition. The petitioner must prove incapacity by clear and convincing evidence — a demanding standard. In a contested case, that burden becomes the central battleground.
The Correct Court: Nassau County Supreme Court for Adults
Accuracy about jurisdiction matters because filing in the wrong court wastes time and money. On Long Island:
| Type of Guardianship | Governing Law | Where It Is Filed (Nassau County) |
|---|---|---|
| Adult — incapacitated person | MHL Article 81 | Supreme Court, Nassau County (the Supreme Court) |
| Minor’s person or property | SCPA Article 17 | Nassau County Surrogate’s Court |
| Developmentally / intellectually disabled person (often a child turning 18) | SCPA Article 17-A | Nassau County Surrogate’s Court |
The single most important point: an adult Article 81 guardianship is heard in the Supreme Court, not the Surrogate’s Court. Contests over the care of an incapacitated parent, spouse, or sibling belong in Supreme Court, Nassau County. Disputes over a minor or a developmentally disabled young adult are handled by the Surrogate’s Court under SCPA Article 17 or 17-A. To learn more about each track, see our Article 81 Guardianship and Guardianship of Minors pages.
How a Contested Article 81 Case Unfolds
An Article 81 proceeding is commenced by filing an Order to Show Cause together with a Verified Petition. From there, a contested case moves through several stages:
1. Appointment of a Court Evaluator
Early in the case, the Nassau County Supreme Court appoints a court evaluator — an independent attorney who investigates the facts, interviews the AIP and family members, reviews medical and financial records, and reports to the judge. In a contested case, the court evaluator’s report often carries significant weight. The court may also appoint counsel for the AIP, especially when the AIP objects.
2. The AIP’s Rights
The AIP is not a bystander. Article 81 guarantees the AIP the right to be present, the right to a hearing, the right to present evidence, and the right to cross-examine witnesses. A skilled attorney uses these rights — on either side — to test whether the evidence truly meets the clear-and-convincing standard.
3. The Hearing
At the hearing, the petitioner must show two things: (1) the person cannot manage property and/or personal needs, and (2) the person is likely to suffer harm because they cannot adequately appreciate the consequences of that inability. Medical testimony, financial records, and witness accounts are weighed. The respondent’s counsel challenges the sufficiency and credibility of that proof.
4. The Least-Restrictive Outcome
Even where some incapacity is established, Article 81 requires the court to grant only the least restrictive intervention tailored to the person’s actual needs. The court can appoint a personal-needs guardian, a property-management guardian, or both — and can limit the powers narrowly. Many contests are won not by defeating the petition outright, but by narrowing the powers so the AIP keeps as much autonomy as possible.
Common Long Island Guardianship Disputes
Across Nassau County — from Massapequa to Manhasset — contested guardianships tend to follow recognizable patterns:
- Sibling rivalry over an aging parent. Two adult children each believe they should control Mom’s finances and care. Each files competing petitions; the court decides who is best suited.
- Allegations of financial exploitation. A petitioner alleges that one relative or caregiver has been draining accounts. These cases often involve forensic review of bank records and may lead to the appointment of a neutral guardian.
- A valid power of attorney already exists. The respondent argues a guardianship is unnecessary because the AIP already executed a durable power of attorney under GOL §5-1513 and a health care proxy. Courts genuinely prefer these less restrictive alternatives.
- The AIP fights back. The person at the center insists they are fine. With counsel and the court evaluator involved, the case turns on whether the proof clears the clear-and-convincing bar.
Why Skilled Counsel Decides the Outcome
Contested guardianships are evidence-driven, deadline-sensitive, and emotionally charged. The difference between a strong and a weak case often comes down to preparation: assembling persuasive medical and financial proof, framing the requested powers as the least restrictive option, anticipating the court evaluator’s concerns, and presenting credible testimony at the hearing.

After Appointment: What a Guardian Must Do
A contest does not end at appointment. Once named, an Article 81 guardian carries ongoing obligations:
- File an initial report within 90 days of appointment.
- File annual reports thereafter, accounting for finances and the AIP’s condition.
- Visit the incapacitated person at least four times per year.
- Act only within the powers the court actually granted.
Guardianship generally lasts for the person’s lifetime unless the court terminates or modifies it — for example, if the person recovers capacity or if a less restrictive arrangement becomes appropriate. These duties are explained further on our Guardian Duties page.
Could the Dispute Be Avoided?
Many guardianship contests trace back to a failure to plan. New York courts strongly favor exploring alternatives to guardianship before imposing one, including:
- A durable Power of Attorney (GOL §5-1513)
- A Health Care Proxy
- A Living Trust or Supplemental/Special Needs Trust
- Supported Decision-Making
When these tools are properly in place, a contested guardianship may be unnecessary altogether. Explore the options on our Alternatives to Guardianship page. When the dispute is already underway, our Contested Guardianship team is ready to act.
Frequently Asked Questions
Where is a contested adult guardianship filed on Long Island?
An adult (Article 81) guardianship of an incapacitated person is filed in Supreme Court, Nassau County — not the Surrogate’s Court. The Surrogate’s Court handles guardianships of minors (SCPA Article 17) and developmentally disabled persons (SCPA Article 17-A).
What must a petitioner prove in a contested Article 81 case?
The petitioner must show, 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 adequately appreciate the consequences. This is a high standard that contested cases test rigorously.
Who is the court evaluator and why do they matter?
The court evaluator is an independent attorney appointed by the Nassau County Supreme Court to investigate and report on the AIP’s situation. In contested cases, their findings often heavily influence whether — and how broadly — a guardianship is granted.
Can a guardianship be avoided if my parent already signed a power of attorney?
Often, yes. If a valid durable power of attorney (GOL §5-1513) and health care proxy are in place, the court may find guardianship unnecessary because less restrictive tools already address the person’s needs. Courts prefer these alternatives.
Can I challenge who is appointed as guardian?
Yes. An interested party can file a cross-petition asking to be appointed instead, or object to the proposed guardian’s suitability. The court selects the guardian it finds best able to serve the incapacitated person’s interests.
