Whether your loved one is an aging parent in Huntington, an adult child with developmental disabilities in Babylon, or a minor who has inherited assets in Smithtown, the path to a legal guardianship in Suffolk County begins with filing in the correct court — and proving the right legal standard.
Which Court Handles Your Case?
| Track | Governing Law | Court | Standard |
|---|---|---|---|
| Adult incapacitated person (AIP) | MHL Article 81 | Supreme Court, Suffolk County | Clear and convincing evidence of incapacity + likely harm |
| Minor’s person or property | SCPA Article 17 | Suffolk County Surrogate’s Court | Best interests of the child |
| Developmentally/intellectually disabled person | SCPA Article 17-A | Suffolk County Surrogate’s Court | Plenary incapacity; common at age 18 transition |
The Article 81 Appointment Process
For adult guardianships under MHL Article 81, the Supreme Court in Suffolk County appoints a Court Evaluator — an independent investigator who meets with the AIP, reviews records, and reports to the judge. The AIP has the right to attend the hearing and to be represented by counsel. Any powers granted must be the least restrictive intervention needed: personal-needs guardianship, property-management guardianship, or both. The guardian then files an initial report within 90 days and annual reports thereafter, with at least four in-person visits per year.
Explore Alternatives First
Before commencing a proceeding, Long Island families should consider whether a Durable Power of Attorney (GOL § 5-1513), Health Care Proxy, or Supplemental Needs Trust can meet their loved one’s needs without court intervention — as Suffolk County judges routinely ask whether less-restrictive options were considered.
