Every probate and administration case on Long Island runs through the county Surrogate's Court. Knowing where to file and what the court needs keeps your estate sale on schedule.

Part of the Guide

This page is part of the Probate Real Estate New York guide. Not legal or tax advice — consult an estate attorney or tax professional for your situation.

What Surrogate's Court Does

It admits wills to probate, appoints executors and administrators, issues Letters, oversees creditor claims, and can resolve disputes among heirs. The county of the decedent's residence controls where you file.

Long Island Court Locations

Nassau County Surrogate's Court: 262 Old Country Road, Mineola. Suffolk County Surrogate's Court: 320 Center Drive, Riverhead. Filing in the correct county is essential.

What You'll File

The original will, certified death certificate, probate or administration petition, and supporting forms. An estate attorney handles the filing; your broker prepares the property in parallel. See the full selling process.

File in the Right County

Use the Surrogate's Court for the county where the decedent legally resided — not where the property sits, if they differ.
