If you have just been named the executor of a parent’s or spouse’s will, here is the fact that surprises most families first: the Long Island probate process almost never moves at the speed of grief. Even a clean, uncontested estate in Nassau or Suffolk County typically takes seven months to well over a year from the day you file the petition to the day the last dollar is distributed — and you cannot legally touch most of the decedent’s assets, sell the house, or pay yourself a commission until the Surrogate’s Court issues you letters testamentary. This guide walks through each stage in the order it actually happens, with the New York statutes and the two Long Island courthouses you will be dealing with in 2026.
What Probate Is — and Which Long Island Court Hears It
Probate is the court-supervised process of proving that a will is valid, formally appointing the person named to administer the estate, and overseeing the orderly payment of debts and distribution of assets. In New York, this work is handled not by a general civil court but by the Surrogate’s Court of the county where the decedent was domiciled at death. For Long Island residents, that means one of two courthouses:
- Nassau County Surrogate’s Court — 262 Old Country Road, Mineola.
- Suffolk County Surrogate’s Court — 320 Center Drive, Riverhead.
Domicile, not where the person happened to die, controls. A Massapequa resident who passed away at a Manhattan hospital is still a Nassau County matter. The governing law lives in two statutes you will see referenced throughout: the Surrogate’s Court Procedure Act (SCPA), which sets the procedure, and the Estates, Powers and Trusts Law (EPTL), which sets the substantive rules about who inherits and how. If the decedent died without a valid will, there is no “probate” of a will at all — instead you file for administration under SCPA Article 10, and the court issues letters of administration rather than letters testamentary. The steps below assume there is a will.
The Long Island Probate Process, Step by Step
The sequence below is the spine of every supervised estate. Each step gates the next — you cannot inventory assets before you have authority, and you cannot distribute before debts and taxes are settled.
Step 1 — File the Probate Petition
The nominated executor files a petition for probate (Form P-1) with the Surrogate’s Court in Nassau or Suffolk, together with the original signed will, a certified death certificate, and a preliminary list of the decedent’s heirs (the “distributees”). The filing fee is set by SCPA § 2402 and is tied to the size of the estate — ranging from $45 for small estates up to $1,250 for estates of $500,000 or more. The petition must value the estate and identify every distributee who would inherit if the will did not exist, because those people have a right to object.
Step 2 — Give Notice to Heirs (Citation and Waivers)
This is the step that protects everyone’s due-process rights and, when it goes wrong, the step that adds months. Every distributee must either sign a waiver and consent or be served with a citation directing them to appear in court on a return date. If all heirs sign waivers, the matter moves quickly. If even one cannot be located — or refuses to sign — the court issues a citation that must be served, sometimes by publication, before the will can be admitted. Understanding who counts as a distributee and the duties that follow is exactly why many families review an overview of executor duties before they ever set foot in Mineola or Riverhead.
Step 3 — The Court Admits the Will and Issues Letters Testamentary
Once notice is complete and no valid objection stands, the Surrogate admits the will to probate and issues letters testamentary — the single most important document in the entire process. Letters are your legal proof of authority. Banks, brokerages, and title companies will demand a certified copy (usually dated within the last 60 days) before they let you move a penny. If the matter is contested or notice is incomplete but the estate has urgent needs, the court can issue preliminary letters testamentary under SCPA § 1412 so the executor can act while the dispute is resolved.
Step 4 — Marshal and Inventory the Assets
With letters in hand, the executor “marshals” the estate: opening an estate bank account, retitling accounts, securing real property, and creating a complete inventory of assets as of the date of death. New York requires this inventory be filed within six months of the issuance of letters (22 NYCRR § 207.20). Only probate assets belong here — assets that pass by beneficiary designation or joint ownership (life insurance, most retirement accounts, joint bank accounts) bypass probate entirely.
Step 5 — Pay Debts, Expenses, and Taxes
Before any heir receives a distribution, the executor pays the decedent’s valid debts, funeral and administration expenses, and taxes in the priority order set by SCPA § 1811. This includes filing a final income tax return and, where the estate is large enough, a New York State estate tax return. For 2026, New York’s estate tax applies to estates above the state exemption (indexed annually), and the state’s notorious “cliff” can tax the entire estate — not just the excess — when the estate exceeds 105% of the exemption. Federal estate tax returns are required only for far larger estates.
Step 6 — Account and Distribute
Finally, the executor prepares an accounting — a detailed ledger of everything that came in, everything paid out, and what remains. Most Long Island estates close by informal accounting, where the beneficiaries review the numbers and sign a “Receipt, Release and Refunding Agreement.” If a beneficiary refuses to approve, the executor petitions for a judicial accounting under SCPA Article 22 and the Surrogate audits the estate formally. Once the accounting is approved, assets are distributed per the will and the estate is closed.
How Long and How Much: A Realistic Long Island Timeline
Families always ask two questions: how long, and how much. The honest answer is that it depends almost entirely on whether anyone objects and whether the assets are simple. The table below reflects typical 2026 ranges for an uncontested Nassau or Suffolk estate.
| Stage | Typical Timeframe | Key Statute / Rule |
|---|---|---|
| File petition + gather waivers | 1–3 months | SCPA § 1402; § 2402 (fees) |
| Citation served (if no waivers) | +2–4 months | SCPA § 1403 |
| Will admitted, letters issued | 2–6 months from filing | SCPA § 1408, § 1414 |
| Inventory of assets filed | Within 6 months of letters | 22 NYCRR § 207.20 |
| Pay debts and taxes | 7–9 months (creditor window) | SCPA § 1802, § 1811 |
| Accounting + distribution | 9–18 months total | SCPA Article 22 |
One number worth circling: SCPA § 1802 gives creditors seven months from the issuance of letters to present claims. A careful executor does not make full distribution before that window closes, because distributing early can leave the executor personally liable for a late but valid claim.
Long Island Scenarios That Change the Math
The Family Home in Levittown or Huntington
Real estate is the most common Long Island probate asset and the one that most often dictates timing. If the house was owned solely in the decedent’s name, it is a probate asset that the executor must secure, insure, and often sell. If it was held as “joint tenants with right of survivorship” or as “tenants by the entirety” between spouses, it passes outside probate to the survivor — no Surrogate’s Court approval needed to transfer title. Many disputes turn on exactly how the deed reads.
The Small Estate Shortcut
If the decedent’s probate assets total $50,000 or less (excluding real property), the estate may qualify for a streamlined voluntary administration under SCPA Article 13 — a simplified affidavit procedure that skips full probate entirely. This is a meaningful shortcut for modest Long Island estates where the home passed by survivorship and only a few bank accounts remain.
The Out-of-Date or Contested Will
When a will is decades old, references property that no longer exists, or favors one child over another, objections become more likely. A disinherited child, a questionable late-life amendment, or allegations of undue influence can convert a routine filing into litigation. Our guide to contested estates and will contests explains how objections are raised and what the SCPA § 1404 examination process looks like in practice.
Common Mistakes Executors Make on Long Island
- Distributing too early. Paying out beneficiaries before the seven-month creditor window closes can leave you personally on the hook for a late claim.
- Co-mingling funds. Estate money must live in a dedicated estate account under the estate’s EIN — never the executor’s personal account.
- Missing the inventory deadline. The six-month inventory filing under 22 NYCRR § 207.20 is easy to overlook and can draw a court inquiry.
- Forgetting the New York estate-tax cliff. An estate just over the exemption can owe tax on the whole value, not just the overage — a costly surprise on appreciated Long Island real estate.
- Improper notice. Failing to properly cite a hard-to-find distributee is the single most common reason a Nassau or Suffolk petition stalls.
- Skipping the accounting. Distributing without a clear accounting and signed releases exposes the executor to a later judicial accounting and personal claims.
The executor is a fiduciary. Every dollar must be accounted for, and good faith is not a defense to a sloppy distribution — documentation is.
When to Call a Long Island Probate Attorney
Some estates are simple enough to handle with the court’s self-help resources and the official Nassau County Surrogate’s Court forms. But the moment any of the following appears, the cost of a mistake outweighs the cost of counsel: a contested or ambiguous will, a missing or hostile distributee, real property that must be sold, an estate large enough to trigger New York or federal estate tax, or a beneficiary who refuses to sign a release. In those situations it is worth taking time to speak with a Long Island estate attorney before you file rather than after a problem surfaces.

Frequently Asked Questions
How long does the probate process take on Long Island in 2026?
An uncontested Nassau or Suffolk County estate typically takes 9 to 18 months from filing to final distribution. The seven-month creditor claim window under SCPA § 1802 alone prevents most executors from making full distribution earlier. Contested matters, missing heirs, or real estate sales can extend it well beyond a year.
Where do I file for probate if I live on Long Island?
You file in the Surrogate’s Court of the county where the decedent was domiciled at death — Nassau County Surrogate’s Court at 262 Old Country Road in Mineola, or Suffolk County Surrogate’s Court at 320 Center Drive in Riverhead. Where the person died does not control; domicile does.
What are letters testamentary and why do I need them?
Letters testamentary are the court document proving you have legal authority to act as executor. The Surrogate issues them after admitting the will to probate. Banks, brokerages, and title companies will not release or transfer assets without a recent certified copy, usually dated within the last 60 days.
Do all the heirs have to agree before a will is probated?
Heirs (distributees) do not have to agree, but they must receive notice. Each either signs a waiver and consent or is served with a citation to appear. If everyone waives, probate is fast; if a distributee objects or cannot be located, the court must resolve that before admitting the will.
What is the difference between probate and administration in New York?
Probate applies when there is a valid will and results in letters testamentary. Administration applies when someone dies without a will (intestate); the court appoints an administrator under SCPA Article 10 and issues letters of administration, with assets distributed according to EPTL § 4-1.1 rather than a will.
Can a small Long Island estate avoid full probate?
Yes. If the decedent’s probate assets total $50,000 or less, excluding real property, the estate may qualify for voluntary administration under SCPA Article 13 — a simplified affidavit procedure that bypasses full probate. This often applies when the home passed by survivorship and only modest accounts remain.
Will the family home have to go through probate?
It depends on the deed. A home owned solely by the decedent is a probate asset the executor must administer. A home held as joint tenants with right of survivorship, or as tenants by the entirety between spouses, passes automatically to the survivor outside probate, with no Surrogate’s Court approval required to transfer title.
What happens if a beneficiary refuses to approve the executor's accounting?
Most Long Island estates close with an informal accounting and signed Receipt, Release and Refunding Agreements. If a beneficiary refuses to sign, the executor petitions for a judicial accounting under SCPA Article 22, and the Surrogate’s Court formally audits the estate before approving distribution.
