Short answer: New York does not legally require you to hire a lawyer to probate a will, but in Nassau County the practical answer is almost always yes — you should retain one. The Nassau County Surrogate’s Court enforces the Surrogate’s Court Procedure Act (SCPA) and the Estates, Powers and Trusts Law (EPTL) strictly, and a single defective petition, an unserved distributee, or a missing waiver can stall an estate for months. While an executor named in a will can technically file on their own, the procedural complexity, jurisdictional rules, and fiduciary exposure make self-representation a costly gamble for all but the simplest estates. Below, the probate team at Morgan Legal Group explains exactly when you need a lawyer on Long Island, when you may not, and how the Nassau County process works.
What “Probate” Actually Means in Nassau County
Probate is the court-supervised process of proving that a deceased person’s will is valid and granting the named executor legal authority to act. That authority comes in the form of Letters Testamentary — the document banks, brokerages, and title companies demand before they will release a penny of estate assets.
In New York, probate is governed by the SCPA and EPTL and is heard in the Surrogate’s Court of the county where the decedent was domiciled. For Long Island residents of Nassau County, that means the Nassau County Surrogate’s Court. Every petition, citation, and decree in your loved one’s estate will move through that court.
The Nassau County Probate Process, Step by Step
The mechanics are the same statewide, but each Surrogate’s Court has its own clerks, calendars, and local quirks. Here is the sequence under the SCPA:
- File the Petition for Probate with the original will and a certified copy of the death certificate at the Nassau County Surrogate’s Court.
- Obtain jurisdiction over distributees (the decedent’s legal next of kin) — either by securing signed waivers and consents from each, or, if they will not sign, by serving a citation compelling them to appear.
- Return date / decree. Absent any objection, the Surrogate signs a decree admitting the will to probate.
- Letters Testamentary issue under SCPA §1414, formally empowering the executor.
- Administration. The executor collects assets, pays valid debts and taxes, and distributes the remainder to the beneficiaries named in the will.
If the executor needs authority before full probate concludes — for example, to secure a Nassau County home or stop a foreclosure — the court can grant Preliminary Letters Testamentary under SCPA §1412, giving interim power while the case is pending.

When You Probably Do Need a Lawyer
| Situation | Why an Attorney Matters |
|---|---|
| Distributees won’t sign waivers | Citations must be drafted and served precisely; defective service voids jurisdiction. |
| A possible will contest | Objections trigger SCPA 1404 examinations and discovery — never DIY. |
| Real property on Long Island | Nassau home/condo sales require clean Letters and careful title handling. |
| Out-of-state or unknown heirs | Service by publication and due-diligence searches are technical and time-sensitive. |
| Estate near the NY tax threshold | Estate-tax exposure demands precise valuation and filings (see below). |
| Business interests or complex assets | Valuation, creditor claims, and fiduciary accounting raise personal liability. |
In any of these scenarios, an executor acting alone risks personal liability for mistakes. Because the executor is a fiduciary, errors in paying debts, valuing assets, or distributing shares can result in the executor being surcharged (held personally responsible) by the court. Our guide to executor duties explains those obligations in full.
When You Might Not Need Full Probate
Not every Long Island estate requires the full probate process. New York offers a streamlined alternative for modest estates:
- Small Estate / Voluntary Administration (SCPA Article 13). If the decedent’s personal property falls under the statutory small-estate ceiling, a voluntary administrator can settle the estate by affidavit rather than full probate. It is faster and far less expensive.
- The catch: real property is generally excluded from this procedure — a critical limitation on Long Island, where a Nassau County house is often the largest asset. If real estate is involved, you usually cannot use the small-estate shortcut.

How Long Does Probate Take in Nassau County?
An uncontested Nassau County probate typically takes about three to six months from filing to the issuance of Letters Testamentary. The single biggest accelerator is getting every distributee to sign a waiver and consent up front — that lets the Surrogate sign the decree without waiting for a citation return date. Contested matters, missing heirs, or estate-tax filings can extend the timeline considerably.
What Does It Cost to Probate a Will?
There are two cost buckets:
- Court filing fee. Under SCPA §2402, the Surrogate’s Court filing fee is graduated according to the size of the estate — larger estates pay more. Because these figures are set by statute and periodically adjusted, do not rely on a number you read online; confirm the current fee with the Nassau County Surrogate’s Court or your attorney.
- Attorney fees. For a typical uncontested Long Island probate, legal fees generally range from about $3,000 to $10,000, depending on the estate’s size and complexity. Contested matters cost more.
A Note on New York Estate Tax (2026)
Most Nassau County estates owe no New York estate tax, but high-net-worth Long Island families must watch the threshold. For 2026, New York’s basic exclusion amount is $7,350,000. New York also enforces a notorious “cliff”: once an estate exceeds 105% of the exclusion — $7,717,500 — the entire estate (not just the excess) becomes taxable. Estates approaching this figure need careful planning; the margin for error is unforgiving.
Frequently Asked Questions
Can I probate a will in Nassau County without a lawyer?
Yes, New York law permits a named executor to file pro se (without counsel). In practice, however, the SCPA’s procedural requirements — petitions, jurisdiction over distributees, and fiduciary accounting — make self-representation risky for anything beyond the simplest estate. Most executors retain counsel.
Where do I file to probate a Long Island will?
If the decedent was domiciled in Nassau County, you file in the Nassau County Surrogate’s Court. The court has jurisdiction over the estate of any person who lived in the county at death.
What gives an executor legal authority?
Letters Testamentary, issued by the Surrogate under SCPA §1414, are the executor’s proof of authority. Banks and other institutions will not release assets without them. If interim authority is needed sooner, Preliminary Letters Testamentary are available under SCPA §1412.
Do I always have to go through full probate?
No. If the estate qualifies as a small estate under SCPA Article 13, a simpler affidavit-based voluntary administration may apply — though it generally excludes real property, a common obstacle on Long Island.
