When a Long Island resident passes away owning assets in their sole name, those assets rarely transfer to the heirs on their own. In Nassau County, the path forward runs through the Nassau County Surrogate’s Court, the dedicated court in Mineola that handles wills, estates, and the appointment of executors for everyone who lived in or owned property in the county. Whether the decedent lived in Garden City, Hempstead, Great Neck, Long Beach, Oyster Bay, or any of Nassau’s other communities, the estate is administered under the same body of New York law and through this single county court.
This guide explains how probate actually works in Nassau County in 2026: what documents you file, how the court appoints an executor, how long it takes, what it costs, and how the process differs for smaller estates. Morgan Legal Group and attorney Russel Morgan, Esq. prepare and prosecute these petitions across Long Island, and the pages below walk through each piece in detail.
What Probate Means in New York
Probate is the court-supervised process of proving that a will is valid and granting the named executor legal authority to act. New York probate is governed by two statutes working together: 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. Every estate is heard in the Surrogate’s Court of the county where the decedent was domiciled — for Long Islanders in this county, that is the Nassau County Surrogate’s Court.
The central goal of probate is the issuance of Letters Testamentary. These are the court documents that prove an executor’s authority — the paper a bank, brokerage, or title company will demand before it releases a dime or transfers a deed. Without Letters, even an executor explicitly named in the will has no power to act. Our probate overview lays out the full framework, and the Surrogate’s Court guide explains how the Nassau court itself operates.
The Nassau County Probate Process, Step by Step
The mechanics are sequential. Each step builds on the one before it, and missing a requirement at any stage stalls the entire estate.
| Step | What Happens | Governing Rule |
|---|---|---|
| 1. File the petition | Submit a Petition for Probate with the original will and a certified death certificate to the Nassau County Surrogate’s Court | SCPA |
| 2. Establish jurisdiction | The court must have jurisdiction over all distributees (heirs at law) through signed waiver and consent forms or, if they will not sign, a formal citation | SCPA |
| 3. Return date / decree | If no one files objections, the court signs a decree granting probate on the return date | SCPA |
| 4. Letters issue | The court issues Letters Testamentary to the executor | SCPA §1414 |
| 5. Administer the estate | The executor collects assets, pays debts and taxes, and distributes what remains | EPTL / SCPA |
A few of these steps deserve a closer look for Nassau families.
Filing the Petition
The petition identifies the decedent, the proposed executor, the named beneficiaries, and the distributees — the people who would inherit under New York’s intestacy rules if there were no will. The original will must accompany the petition; a photocopy is not sufficient absent special proceedings. A certified copy of the death certificate is also required. The filing fee is graduated according to the size of the estate under SCPA §2402, so the exact dollar amount depends on the estate’s value. Because the fee schedule can change, confirm the current figure with the Nassau County Surrogate’s Court or your attorney before filing.
Getting Jurisdiction Over the Distributees
This is where many Nassau probates speed up or slow down. The court needs jurisdiction over every distributee, even those who receive nothing under the will. The fastest route is to have each distributee sign a waiver and consent, voluntarily agreeing to the will’s admission. When a distributee refuses to sign or cannot be located — common when family members are scattered across Long Island, the boroughs, or out of state — the court issues a citation directing them to appear. This adds time and process, since the citation must be properly served.
Letters Testamentary and Preliminary Letters
Once the decree is signed, Letters Testamentary issue under SCPA §1414, and the executor is finally empowered to act. Because the full process takes months, New York allows the court to grant Preliminary Letters Testamentary under SCPA §1412 — interim authority that lets the executor begin managing the estate (securing accounts, protecting Long Island real estate, paying urgent bills) while the probate petition is still pending. Preliminary Letters are a practical tool when a Nassau estate has time-sensitive assets, such as a business, a home that must be insured and maintained, or accounts that need to be consolidated.

Timeline and Cost for Nassau County Estates
Families on Long Island understandably want to know how long this takes and what it costs. For an uncontested estate where all distributees sign waivers, probate in Nassau County typically runs three to six months from filing to issuance of Letters. Contested matters — where someone files objections to the will — take substantially longer and follow a litigation track.
Attorney fees for handling a probate generally fall in the $3,000 to $10,000 range, depending on the complexity of the estate, the number of distributees, whether real property or a business is involved, and whether any disputes arise. Add the graduated court filing fee set by SCPA §2402, which scales with the estate’s value.

Small Estates: A Faster Path for Some Nassau Families
Not every estate requires full probate. When the decedent’s personal property passing through the estate is modest, New York offers a streamlined alternative called voluntary administration under SCPA Article 13 — often called the small estate or “small estate affidavit” procedure. Instead of a full petition and decree, a voluntary administrator files an affidavit and is appointed to collect and distribute the limited assets. This is faster and far less expensive than full probate.
There is an important limitation for Long Island homeowners: real property is generally excluded from the Article 13 process. If the Nassau estate includes a house, condominium, or co-op interest that must pass through the estate, the small estate route usually will not reach it, and full probate or administration may still be necessary. Our small estate affidavit page explains who qualifies and how to use this procedure.
New York Estate Tax in 2026
Estate tax is a separate question from probate, but it matters greatly for higher-net-worth Long Island families, where real estate values alone can push an estate toward the threshold. For 2026, the New York basic exclusion amount is $7,350,000. New York also has a notorious “cliff“: once a taxable estate exceeds 105% of the exclusion — $7,717,500 — the exclusion is lost entirely and the whole estate becomes taxable, not just the excess. For Nassau estates approaching that line, careful planning is essential, and the executor should coordinate with counsel and a tax professional. Current figures and forms are published by the New York State Department of Taxation and Finance.
When Probate Is Contested in Nassau County
Most Nassau probates proceed quietly, but disputes do arise — challenges to a will’s validity, claims of undue influence or lack of capacity, or disagreements among siblings over an executor’s conduct. When a distributee files objections, the matter moves from an administrative process into Surrogate’s Court litigation, with discovery, examinations under SCPA 1404, and potentially a trial. These cases demand experienced counsel. Learn more on our contested probate page.
Frequently Asked Questions
Which court handles probate for a Nassau County resident?
The Nassau County Surrogate’s Court has jurisdiction over the estate of anyone who was domiciled in Nassau County at death, regardless of which Long Island town or village they lived in. The petition, original will, and certified death certificate are filed there, and that court issues the Letters Testamentary.
How long does uncontested probate take in Nassau County?
An uncontested Nassau estate — one where all distributees sign waivers and no objections are filed — typically takes about three to six months from filing to the issuance of Letters Testamentary. Contested estates take considerably longer.
What are Letters Testamentary and why does the executor need them?
Letters Testamentary are the court documents, issued under SCPA §1414, that prove the executor’s legal authority to act for the estate. Banks, brokerages, and title companies require them before releasing assets or transferring property. If urgent matters arise while probate is pending, the court can grant Preliminary Letters Testamentary under SCPA §1412.
How much does probate cost in Nassau County?
Attorney fees generally run $3,000 to $10,000 depending on the estate’s complexity, plus a court filing fee that is graduated by estate value under SCPA §2402. Because the fee schedule can change, confirm the current amount with the Nassau County Surrogate’s Court or your attorney.
Can a small Nassau estate avoid full probate?
Possibly. If the personal property passing through the estate is modest, SCPA Article 13 voluntary administration allows a faster affidavit-based process. However, real property is generally excluded, so a Long Island estate that includes a house or co-op typically still requires full probate or administration.
