For most families on Long Island, an uncontested probate in the Nassau County Surrogate’s Court takes roughly three to six months from the day the petition is filed to the day the executor receives Letters Testamentary and can begin administering the estate. That is the short answer. The longer answer depends on a handful of factors — how quickly you can locate the original will and certified death certificate, whether every distributee signs a waiver and consent, whether anyone files objections, and how busy the court calendar is in any given month. This guide walks you through the realistic 2026 timeline step by step so you know what to expect before you ever set foot in the Surrogate’s Court in Mineola.
Probate is the court-supervised process that proves a will is valid and formally appoints the person named to settle the estate. In New York, probate is governed by the Surrogate’s Court Procedure Act (SCPA) and the Estates, Powers and Trusts Law (EPTL), and it is heard in the Surrogate’s Court of the county where the decedent lived. For a Nassau County resident, that means the Nassau County Surrogate’s Court. The court’s job is to confirm the will, resolve any disputes, and issue Letters Testamentary under SCPA §1414, which give the executor legal authority to act on behalf of the estate.
The Nassau County Probate Timeline at a Glance
The chart below shows a typical, uncontested probate. Treat these ranges as planning estimates, not guarantees — every estate is different.
| Stage | What Happens | Typical Time |
|---|---|---|
| Gathering documents | Locate the original will, order the certified death certificate, identify distributees | 1–3 weeks |
| Preparing & filing the petition | Draft the Petition for Probate, attach the will and death certificate, file with the court | 1–4 weeks |
| Obtaining jurisdiction | Collect signed waivers and consents from all distributees, or issue a citation if any will not sign | 2–8 weeks |
| Decree & Letters issue | Court reviews the file; on the return date, absent objection, the decree is signed and Letters Testamentary issue | 1–4 weeks |
| Administration | Executor collects assets, pays debts and taxes, files accountings, and distributes to beneficiaries | 6–18+ months |
So while the appointment of an executor often happens within three to six months, fully closing an estate — paying creditors, handling any tax returns, and distributing the assets — frequently runs a year or more. The two timelines are different, and confusing them is the most common reason families feel blindsided. For a fuller walkthrough of the process, see our Probate Overview and our Surrogate’s Court Guide.
Step One: Filing the Petition for Probate
Everything begins with the Petition for Probate. The person named as executor (the “petitioner”) files this petition together with the original signed will and a certified copy of the death certificate in the Nassau County Surrogate’s Court. A photocopy of the will is generally not acceptable — the court wants the original. The petition lists the decedent’s heirs and the beneficiaries named in the will, identifies the estate’s approximate value, and asks the court to admit the will to probate and issue Letters Testamentary.
The court charges a filing fee that is graduated by the value of the estate under SCPA §2402. We deliberately do not quote a dollar figure here because the fee tiers depend on the gross estate; confirm the exact amount with the court or your attorney before filing.
Step Two: Getting Jurisdiction Over the Distributees
This is the stage that most often controls your timeline. Before the court can admit the will, it must have jurisdiction over the decedent’s distributees — the people who would inherit under New York’s intestacy law if there were no will. There are two ways to accomplish this:
- Waiver and Consent. Each distributee signs a document agreeing to the will being probated and waiving the right to a formal citation. When everyone cooperates, this is fast and keeps the case moving.
- Citation. If a distributee will not sign, cannot be located, or is a minor or under a disability, the court issues a citation — essentially a summons directing that person to appear on a return date. Serving citations, especially on out-of-state or hard-to-find heirs, adds weeks or months.
If every distributee signs a waiver and consent, you can often skip much of the waiting and proceed straight toward the decree.
Step Three: The Decree and Letters Testamentary
Once the court is satisfied that the will is valid and jurisdiction is complete, the Surrogate signs a decree granting probate. On the return date, absent any objection, the decree is entered and Letters Testamentary issue under SCPA §1414. These Letters are the document banks and brokerages will ask to see before they release accounts to the executor. Understanding what comes next is essential — read our guide to Executor Duties to see exactly what the law expects of a fiduciary once Letters are in hand.
What If You Need Authority Sooner?
If an estate needs someone with authority before probate is complete — for example, to secure property, stop a foreclosure, or manage a business — the court can issue Preliminary Letters Testamentary under SCPA §1412. These give the named executor interim authority to act while the probate petition is still pending, which is a valuable tool when time is critical.
What Slows a Nassau County Probate Down?
Several issues can stretch a three-to-six-month case into a much longer one:
- A will contest. If a distributee files objections — alleging undue influence, lack of capacity, improper execution, or fraud — the case becomes a litigated contested probate with discovery, depositions (SCPA §1404 examinations), and possibly a trial. This can add many months or even years. If you are facing a dispute, see our overview of Contested Probate.
- Missing or hard-to-locate heirs. Heirs who cannot be found require diligent search efforts and sometimes a guardian ad litem.
- A missing original will. Proving a lost will adds significant procedural hurdles.
- Estate tax filings. Larger estates that must file a New York estate tax return have additional steps before the estate can close.
Do You Even Need Full Probate? Small Estates on Long Island
Not every estate requires a full probate. If the decedent owned a limited amount of personal property (real estate is generally excluded), the estate may qualify for voluntary administration under SCPA Article 13 — a streamlined affidavit procedure that avoids a full probate proceeding. This is often dramatically faster and less expensive. Learn more on our Small Estate Affidavit page to see whether your situation qualifies.
What Does Probate Cost in Nassau County?
Attorney’s fees for an uncontested Nassau County probate commonly range from about $3,000 to $10,000, depending on the size and complexity of the estate. On top of that is the court’s graduated filing fee under SCPA §2402. A contested matter costs more because of the litigation involved.
As for estate taxes, the New York estate tax exclusion amount for 2026 is $7,350,000. New York uses a “cliff”: if a taxable estate exceeds 105% of the exclusion — $7,717,500 in 2026 — the entire estate becomes taxable, not just the amount over the threshold. Most Nassau County estates fall well under this figure, but high-value estates should plan carefully with counsel.
Frequently Asked Questions
How long does probate take in Nassau County if nobody contests the will?
An uncontested Nassau County probate typically takes about three to six months from filing to the issuance of Letters Testamentary, assuming the original will and certified death certificate are available and all distributees sign waivers and consents.
Can the executor act before probate is finished?
Yes. The court can issue Preliminary Letters Testamentary under SCPA §1412, giving the named executor interim authority to manage urgent matters while the probate petition is still pending.
What makes probate take longer than six months?
The most common causes are will contests, missing or unlocatable heirs, a lost original will, and estate tax filings for larger estates. Any of these can add months or, in litigated cases, years.
Is there a way to avoid full probate for a small estate?
Possibly. If the decedent left only a modest amount of personal property — real property is generally excluded — the estate may qualify for voluntary administration under SCPA Article 13, a faster affidavit-based alternative to full probate.
