How to File for Guardianship in New York: Step by Step

Guardianship is sometimes necessary when an adult family member can no longer manage their personal care or finances due to illness, cognitive decline, or incapacity. New York law provides a court process through which the Supreme Court can appoint a guardian to manage the incapacitated person’s affairs.

For Westchester County families, understanding the guardianship process is important if you are considering filing, or if a court has suggested guardianship as a solution for managing a loved one’s care. This guide walks through the step-by-step process, from determining whether guardianship is appropriate to obtaining a final court order.

Understanding MHL Article 81

New York’s Mental Hygiene Law (MHL) Article 81 governs guardianship for incapacitated adults, providing a formal court process to protect people who can no longer care for themselves or manage their property. The guardianship is court-ordered (only courts can appoint guardians), requires proof of incapacity, mandates consideration of less restrictive alternatives, and imposes fiduciary duties on guardians to act in the incapacitated person’s best interest.

Types of Guardianship in New York

Before filing, you must determine what type of guardianship is appropriate.

Guardian of the person. A guardian of the person makes decisions about the incapacitated person’s health care, medical treatment, living arrangements, education, and personal welfare. This type of guardian does not manage finances.

Guardian of the property (conservator). A guardian of the property manages the incapacitated person’s financial affairs, real property, and investments. This guardian does not make personal or health care decisions.

Guardian of both the person and property. One person can serve as guardian of both the person and property, making both personal and financial decisions.

The petition must specify which type of guardianship you are seeking. Often, one guardian manages finances while another (or the same person) makes health care decisions.

Step One: Determine if Guardianship Is Appropriate

Before filing a petition, evaluate whether guardianship is truly necessary.

Is there actual incapacity? The person must be incapable of managing their personal or financial affairs. A diagnosis alone (such as dementia or mental illness) is not sufficient. The person must lack the ability to understand and appreciate the consequences of refusing treatment or making decisions about care.

What is the legal standard? Under MHL 81.2, the person must be unable to care for themselves or manage their property, or to make decisions about their care or property. This is a high legal standard. The court will only appoint a guardian if it finds clear and convincing evidence of incapacity.

Are there less restrictive alternatives? Before filing for guardianship, consider:

• Powers of attorney (if the person still has capacity to execute one)
• Health care proxies or HIPAA releases
• Representative payee arrangements for Social Security or other benefits
• Representative conservatorship (a less restrictive form of conservatorship for property)
• Money management services
• A revocable trust with a successor trustee

If the person still has some capacity and understanding, they may be able to execute a power of attorney or health care proxy, avoiding the need for court-ordered guardianship.

Is the incapacity likely to be temporary? If the person’s incapacity is temporary (for example, due to a short-term illness or injury), a limited guardianship for a specific period might be appropriate, rather than permanent guardianship.

If you are unsure whether guardianship is necessary, consult with an experienced guardianship attorney. They can advise on your specific situation and whether guardianship is the best approach.

Step Two: Gather Medical and Personal Documentation

The guardianship petition requires detailed medical evidence of incapacity. You will need:

Medical evaluation from a licensed physician. Obtain an affidavit from a licensed physician (MD, DO, or advanced nurse practitioner) who has examined the person within the past 30 days. The affidavit must describe the person’s medical condition, specific ways they cannot care for themselves or manage property, whether incapacity is permanent or temporary, the exam date, and the physician’s qualifications.

Documentation of assets and liabilities. Gather records showing bank accounts, investments, real property, debts, income sources, and insurance policies. This documentation helps the court understand the scope of property needing management.

Documentation of the person’s wishes. If the person has expressed preferences about health care, living arrangements, or financial decisions, document these. The guardian should try to honor the person’s preferences when making decisions.

Affidavit of fitness and interest. Submit an affidavit stating your relationship to the person, reasons for seeking guardianship, willingness to serve, understanding of duties and responsibilities, and any conflicts of interest.

Step Three: File the Guardianship Petition

The petition is filed with the Supreme Court in the county where the incapacitated person resides. In Westchester County, petitions are filed with the Westchester County Supreme Court. Required contents include the person’s name, age, residence, a specific description of incapacity with supporting facts, the proposed guardian’s information, whether seeking guardianship of person/property/both, medical evidence, guardian affidavit, and proof of notification.

Once filed, the court assigns a case number and judge, and you receive notice of your assigned judge and future court dates.

Step Four: Notification and Service of Process

New York law requires that the incapacitated person be notified of the guardianship petition and have an opportunity to respond.

The incapacitated person must be served with notice. Notice must be personally delivered to the person (not sent by mail). You or a process server must deliver a copy of the petition, affidavit, and court notice to the person.

The person has the right to an attorney. If the incapacitated person does not have an attorney, the court appoints one at no cost. The attorney represents the person’s interests and may argue against guardianship if the person objects.

The incapacitated person has the right to object. If the person objects to the petition, the case becomes contested, requiring a hearing before a judge.

Step Five: Court Evaluator Appointment (Often Required)

In many cases, the court appoints a court evaluator to investigate the petition and report to the court. The evaluator:

• Meets with the incapacitated person
• Reviews medical records and financial documents
• Interviews the proposed guardian
• Reports to the court on whether guardianship is necessary and appropriate

The court evaluator’s fee (typically $500 to $1,000) is paid by the incapacitated person’s estate or, if the estate cannot pay, by the petitioner.

The evaluation process typically takes 4 to 8 weeks. During this time, the court evaluator gathers information and prepares a report recommending whether the court should appoint a guardian.

Step Six: Hearing (If Contested or Required)

If the incapacitated person objects to guardianship or if the court requires a hearing, you will appear before a judge. The petitioner testifies about incapacity and why guardianship is necessary, the physician testifies about medical evidence, the incapacitated person has opportunity to testify and present evidence, and the court evaluator presents findings. The judge then decides whether to grant guardianship.

If the person objects, the case becomes contested. Contested hearings require more detailed evidence and argument, with the incapacitated person’s attorney cross-examining witnesses and presenting expert testimony.

Step Seven: Court Order and Appointment

Once the court finds that guardianship is appropriate, the judge issues an order appointing you as guardian.

The order specifies:

• Whether you are guardian of the person, property, or both
• Any limitations or restrictions on your powers
• Your duties and responsibilities
• When you must file accountings and medical reports with the court

You will receive a certified copy of the order, which you can use to access the incapacitated person’s accounts, make medical decisions, and exercise other guardianship powers.

Step Eight: Obtain Letters of Guardianship

Once the order is issued, you obtain letters of guardianship from the court clerk. These letters confirm your appointment and are required to:

• Access bank and investment accounts
• Sell or refinance real property
• Make health care decisions
• Enroll in government benefit programs

Step Nine: Fulfill Your Duties as Guardian

Once appointed, the guardian must follow specific legal duties and procedures: file an initial accounting within 13 months, file annual accountings thereafter, file medical reports every three years (if guardian of the person), act in the person’s best interest, maintain detailed records, seek court approval for major decisions, and cooperate with court reviews.

Guardianship Timeline and Costs

Total cost for uncontested cases: $3,000-$6,000. Total cost for contested cases: $6,000-$15,000+.

Alternatives to Guardianship

Before filing for guardianship, consider whether a less restrictive alternative would work:

Power of attorney. If the person still has capacity, they can execute a power of attorney authorizing someone to manage their finances. This avoids the need for court involvement.

Health care proxy. A health care proxy document authorizes someone to make medical decisions. This is less formal than guardianship of the person.

Representative payee. If the person receives Social Security benefits, you can become a representative payee authorized to manage the benefits.

Money management services. Some banks and investment firms offer money management services for individuals who need assistance with finances.

Revocable trust with successor trustee. If the person created a trust, the successor trustee can manage trust assets without guardianship.

When Guardianship Ends

Guardianship continues until one of the following occurs:

• The incapacitated person regains capacity (rare)
• The incapacitated person dies
• The guardian petitions the court to terminate guardianship (if appropriate)
• The court finds that guardianship is no longer necessary

When the incapacitated person dies, the guardian’s powers end, and the person’s estate goes through probate or small estate procedures.
