When a Long Island resident passes away leaving a will, that will rarely takes effect on its own. Before a named executor can sell the house in Huntington, close the bank accounts in Riverhead, or distribute a parent’s estate to children in Babylon or Smithtown, the will usually must be proven valid through probate in the Suffolk County Surrogate’s Court. This site is built around one idea: walking you through the full probate process from the first petition to the final distribution, with specifics that matter to families across Suffolk County rather than generic statewide advice.
Probate is governed by New York’s Surrogate’s Court Procedure Act (SCPA) and the Estates, Powers and Trusts Law (EPTL), and every contested or uncontested will of a Suffolk resident is heard in the county’s Surrogate’s Court. Whether the estate is a modest home in Patchogue or a waterfront property on the East End, the legal framework is the same — and so is the value of getting the steps right the first time.
What “Full Probate” Means in Suffolk County
Full probate is the complete court-supervised process of validating a will and empowering the executor. In Suffolk County, that means filing in the Surrogate’s Court that serves the towns of Huntington, Islip, Brookhaven, Babylon, Smithtown, Southampton, East Hampton, Riverhead, and the rest of the county. The court confirms the will is genuine, that it was properly signed and witnessed, and then issues the authority the executor needs to act.
The legal instrument that grants that authority is called Letters Testamentary, issued under SCPA §1414. Until the court issues Letters, the named executor has no power to transfer title, access estate accounts, or sign on behalf of the estate. This is why so many Long Island families are surprised to learn they cannot simply “handle things” right after a funeral — the Surrogate’s Court must act first.

The Full Probate Process, Step by Step
The probate of a Suffolk County will follows a defined sequence. Each step has a purpose, and skipping or mishandling one is the most common reason estates stall for months.
- File the Petition for Probate. The executor (or their attorney) files a verified Petition for Probate with the Suffolk County Surrogate’s Court, accompanied by the original will and a certified copy of the death certificate.
- Establish jurisdiction over distributees. The people who would inherit if there were no will — the distributees — must be brought before the court. This is done either by their signed waivers and consents or, if they will not sign, by formal citation requiring them to appear.
- Return date and decree. On the return date, if no one files objections, the Surrogate signs a decree granting probate, admitting the will to probate.
- Letters Testamentary issue. The court issues Letters under SCPA §1414, formally empowering the executor.
- Administer the estate. The executor collects assets, pays valid debts and taxes, and distributes what remains according to the will. Our executor duties page covers these fiduciary obligations in detail.
If the executor needs authority before the will is fully admitted — to secure a property in Sayville or stop a foreclosure clock, for example — the court can issue Preliminary Letters Testamentary under SCPA §1412, giving interim power while the probate petition remains pending.

When Full Probate Isn’t Required: Small Estates
Not every Long Island estate needs the full process. When the decedent’s personal property falls under New York’s small-estate threshold, the estate may qualify for voluntary administration under SCPA Article 13 — a streamlined affidavit procedure that avoids a full probate proceeding. Note that real property is generally excluded from this simplified route, so a Suffolk home in the estate often pushes the matter back toward full administration.

Estate Taxes for Long Island Estates in 2026
Many Suffolk County estates — especially those holding appreciated real estate on the South Fork or North Shore — should watch the New York estate tax closely. For 2026, the New York exclusion amount is $7,350,000. New York’s tax also features a “cliff”: once an estate exceeds 105% of the exclusion ($7,717,500), the exclusion phases out entirely and tax may apply to the whole estate, not just the excess. Given Long Island property values, a single house plus retirement accounts can move an estate closer to these thresholds than families expect, which makes early planning and accurate valuation important.
When Probate Is Contested
Sometimes an heir challenges the will — alleging undue influence, lack of capacity, or improper execution. When that happens, the matter becomes a litigated proceeding in the Suffolk County Surrogate’s Court, with objections, discovery, and potentially a hearing before the Surrogate. These cases require careful handling. Our contested probate page explains how will challenges proceed and how executors and beneficiaries can protect their positions.
