How to File an Article 81 Guardianship Petition in New York

The Filing Starts in the Proper Trial Court, Not Surrogate's Court

A common mistake families make is assuming guardianship proceedings for an elderly parent belong in Surrogate's Court or Family Court. They don't. Article 81 guardianship petitions under New York's Mental Hygiene Law are filed in Supreme Court within the judicial district, or in County Court outside New York City, where the alleged incapacitated person (AIP) resides or is physically present. If the AIP lives in a facility, venue is generally the county where that facility is located.

This distinction matters because Supreme Court has different filing procedures, different clerk's offices, and different fee schedules than the courts most families have dealt with before.

What the Petition Must Include

The Article 81 petition is the core document that starts the proceeding. Under Mental Hygiene Law § 81.08, it must contain specific allegations:

• The AIP's functional limitations — not just a medical diagnosis, but concrete examples of how the person's cognitive or physical decline creates a risk of harm. "Mom has Alzheimer's" isn't enough. You need specifics: she left the stove on three times last month, she wrote checks to a telephone scammer totaling $14,000, she refused to take prescribed blood pressure medication for six weeks.
• Why no less restrictive alternative exists — the court needs to know you've considered whether a power of attorney, health care proxy, or representative payee could address the problem without a guardianship.
• Who you propose as guardian — typically the petitioner, though you can nominate someone else.
• The specific powers requested — Article 81 guardianships are tailored, not blanket. You must identify exactly which powers you need: authority to manage bank accounts, consent to medical treatment, choose a residential placement, apply for Medicaid, sell real property.
• A list of all interested parties — every person entitled to notice of the proceeding, including the AIP, their spouse, adult children, siblings, and anyone already serving as agent under a POA or health care proxy.

The Order to Show Cause

You don't file the petition alone. It must be accompanied by an Order to Show Cause (OSC), which is a proposed court order that the judge signs to schedule the hearing and direct notice to all parties.

The OSC sets the hearing date (typically 28 days out) and specifies who must be served with copies of the petition and the signed order. It may also contain requests for interim relief — for example, a Temporary Restraining Order freezing the AIP's bank accounts if there's evidence of active financial exploitation, or a request for appointment of a temporary guardian under MHL § 81.23 if the situation is urgent enough that 28 days is too long to wait.

Preparing the OSC requires submitting it to the assigned judge's chambers for signature as part of starting the proceeding. Some counties have specific formatting requirements and local rules about what can be included in the OSC.

Filing Fees and Court Costs

The filing fees identified for an Article 81 proceeding are a $210 index-number fee, $95 RJI fee, and $45 OSC fee as of 2026. In addition, the petitioner typically pays for:

• The court evaluator's fee — the court appoints an independent evaluator to investigate the case, and their fee (typically $1,500–$3,000) is usually paid from the AIP's estate, but the petitioner may need to advance it
• Service of process — personal service on the AIP and mail service on all other interested parties
• The guardian ad litem fee (if appointed) — in contested cases, the court may appoint a separate attorney for the AIP
• Legal counsel and proceeding costs — total legal and court evaluator fees typically range from $4,500–$15,000 for an uncontested Article 81 proceeding

The Hearing Timeline

Once the OSC is signed and all parties are served, the case moves on a compressed timeline:

1. Day 0: File the petition and OSC; judge signs the OSC and sets the hearing date
2. At OSC issuance: The court evaluator is appointed and begins their investigation — interviewing the AIP, reviewing medical records, speaking with family members, and inspecting the living situation
3. Day 28 (approximately after the OSC is signed): The hearing takes place before the judge. The AIP has the right to be present, to have their own attorney, and to cross-examine witnesses
4. Post-hearing: If the judge grants the petition, they issue a guardianship order specifying the guardian's exact powers and any restrictions. The guardian must then file a bond (if required) and take an oath before receiving their commission

Contested cases — where siblings disagree about who should be guardian, or where the AIP objects to the proceeding — can extend this timeline by weeks or months, as the court may schedule additional hearings, order independent medical evaluations, or appoint a guardian ad litem.

What the Court Evaluator Actually Does

Every Article 81 proceeding triggers the appointment of a court evaluator under MHL § 81.09. This is an independent court-appointed evaluator — often an attorney with elder-law experience — whose job is to serve as the court's independent investigator. They are not an advocate for the petitioner or the AIP; they report to the judge.

The evaluator must meet with and interview the AIP, explain the nature of the proceeding, and assess their functional capacity. They also interview the proposed guardian, review financial records, and talk to medical providers. Their written report — filed with the court before the hearing — includes a recommendation on whether a guardian should be appointed and what powers they should receive.

The evaluator's recommendation carries significant weight. If the evaluator concludes the petition is warranted and the proposed guardian is suitable, uncontested cases often conclude in a single hearing.

Building a Stronger Petition

The difference between a petition that moves quickly and one that gets bogged down in adjournments often comes down to documentation. Before filing, gather:

• Medical evidence — a letter from the AIP's physician documenting cognitive decline, diagnosis, and functional limitations. Some judges will accept a physician's affidavit in lieu of live testimony at the hearing.
• Financial records — bank statements showing unusual transactions, unpaid bills, evidence of exploitation
• Incident documentation — police reports, APS referrals, hospital records from falls or emergencies
• Evidence that less restrictive alternatives failed — if the parent refused to sign a POA, if an existing POA agent is unable or unwilling to serve, or if the situation is beyond what a POA can address

When an Attorney Is Essential vs. Optional

New York does not require you to hire an attorney to file an Article 81 petition. A family member can file pro se (self-represented). But the procedural requirements are exacting — incorrectly drafted petitions, improper service, or failure to include required allegations can result in dismissal or significant delays.

If the case is uncontested (all family members agree on the need for guardianship and who should serve), a well-prepared pro se filing is feasible. If there's any disagreement among family members, if the AIP has substantial assets, or if another party is likely to object, legal representation is strongly advisable. The court evaluator's investigation proceeds regardless, and having an attorney ensures your petition meets every statutory requirement the first time.
