When a Long Island resident passes away leaving a last will and testament, that will does not transfer property on its own. Before an executor can sell the family home in Garden City, close a bank account in Hempstead, or distribute a brokerage account to the children, the will must be proven valid through a court proceeding called probate. In Nassau County, that proceeding takes place in the Nassau County Surrogate’s Court in Mineola, the dedicated court that handles wills, estates, and trusts for everyone who lived in the county at the time of death.
Probate in New York is governed by the Surrogate’s Court Procedure Act (SCPA) and the Estates, Powers and Trusts Law (EPTL). These statutes apply uniformly across the state, but each county’s Surrogate’s Court has its own clerks, return-date calendars, and local filing practices. This guide walks through each step of the Nassau County probate process so executors and families on Long Island know what to expect.
At Morgan Legal Group, attorney Russel Morgan, Esq. and our team guide Nassau County executors through every stage of probate — from the initial petition to the final distribution.
What Probate Actually Does
Probate has two core legal functions. First, it validates the will — the court confirms that the document offered is the decedent’s genuine, properly executed last will. Second, it appoints the executor and grants that person legal authority through a document called Letters Testamentary. Until those Letters are issued, the named executor has no power to act on the estate’s behalf. Banks, title companies, and transfer agents on Long Island will ask to see certified Letters before they release a single dollar.

The Step-by-Step Probate Process in Nassau County
Step 1 — File the Petition for Probate
The process begins when the person named as executor (the “petitioner”) files a Petition for Probate with the Nassau County Surrogate’s Court. The petition must be accompanied by:
- The original last will and testament (not a photocopy);
- A certified death certificate; and
- Supporting affidavits and the required filing fee.
The court filing fee is graduated based on the value of the estate under SCPA §2402. Because the fee schedule changes with estate size and is periodically updated, we do not quote a fixed dollar figure here — confirm the current amount with the Nassau County Surrogate’s Court or with counsel before filing.
Step 2 — Obtain Jurisdiction Over the Distributees
New York law requires that every distributee — the people who would inherit under the intestacy statute if there were no will — be given the chance to object. The court obtains jurisdiction over them in one of two ways:
- Waiver and Consent: Each distributee signs a document acknowledging the will and consenting to probate. This is the fastest path.
- Citation: If a distributee will not sign, the court issues a citation — a formal notice commanding them to appear on a “return date” and state any objection.
On Long Island, locating and serving distributees who have moved off-island or out of state is one of the most common causes of delay. Careful preparation here keeps a Nassau County estate moving.
Step 3 — The Return Date and Decree
On the return date, if no one files objections, the Surrogate issues a decree granting probate. The will is admitted, and the court is satisfied that the named executor is qualified to serve. If a distributee or interested party does object, the matter becomes a contested probate and proceeds on a litigation track.
Step 4 — Letters Testamentary Issue
Once probate is decreed, the court issues Letters Testamentary under SCPA §1414. This is the executor’s official credential — the proof of authority that Long Island banks, brokerages, and the Nassau County Clerk’s office will require before allowing the executor to act.
When the will must be admitted but the estate needs immediate management — for example, a business that cannot wait or a property that needs urgent attention — the court can issue Preliminary Letters Testamentary under SCPA §1412. These give the nominated executor interim authority while the full probate proceeding is still pending.
Step 5 — Administer and Distribute the Estate
With Letters in hand, the executor’s substantive work begins. The executor must:
- Collect and secure the assets — bank accounts, real property, investments, and personal property.
- Pay valid debts, expenses, and taxes, including any New York estate tax that applies.
- Account to the beneficiaries and distribute what remains according to the will’s terms.

Nassau County Probate Timeline and Cost at a Glance
| Item | What to Expect on Long Island |
|---|---|
| Court | Nassau County Surrogate’s Court (Mineola) |
| Governing law | SCPA + EPTL |
| Typical timeline (uncontested) | ~3–6 months |
| Attorney’s fee (typical range) | ~$3,000–$10,000 |
| Court filing fee | Graduated by estate value — SCPA §2402 (confirm current amount) |
| Executor’s authority | Letters Testamentary — SCPA §1414 |
| Interim authority | Preliminary Letters — SCPA §1412 |
| Small-estate alternative | Voluntary administration — SCPA Article 13 |
An uncontested Nassau County estate often concludes in roughly three to six months. Contested matters, missing distributees, or complex assets can extend that timeline considerably.
When Full Probate Is Not Required: Small Estates
Not every Long Island estate needs full probate. If the decedent’s personal property is modest, the estate may qualify for voluntary administration under SCPA Article 13 — a streamlined, affidavit-based procedure that is faster and less expensive than full probate. An important limitation: real property is generally excluded from the small-estate process, so a house in Levittown or a condo in Long Beach usually pushes an estate back toward full probate or administration. Learn more in our small estate affidavit guide.
New York Estate Tax in 2026
Executors of larger Long Island estates must watch the New York estate tax. For 2026, the basic exclusion amount is $7,350,000. New York also imposes a unique “cliff”: when a taxable estate exceeds 105% of the exclusion — $7,717,500 in 2026 — the exclusion is lost entirely and the whole estate becomes taxable, not just the excess. Because Long Island real estate values are high, an estate can approach the cliff faster than families expect, which makes early planning and accurate valuation essential. Confirm current thresholds with the New York State Department of Taxation and Finance or with counsel.
