Frequently Asked Questions
1. What is probate, and why does it happen in Suffolk County?
Probate is the court-supervised process of proving that a deceased person’s will is valid and authorizing the named executor to act. In New York, it is heard in the County Surrogate’s Court where the decedent was domiciled. For Long Island residents in Suffolk County — from Huntington Station to Sag Harbor — that is the Suffolk County Surrogate’s Court in Riverhead. Once the will is admitted, the court issues Letters Testamentary under SCPA §1414, the document that proves the executor’s authority to act for the estate.
2. What do I need to file to start probate?
To open a probate proceeding, the petitioner files a Petition for Probate together with the original signed will and a certified copy of the death certificate. The court must also obtain jurisdiction over the decedent’s distributees (the heirs who would inherit if there were no will) — either through their signed waivers and consents or, if they will not sign, by serving a citation directing them to appear. Our Surrogate’s Court guide walks through each filing in detail.
3. How long does probate take on Long Island?
An uncontested Suffolk County probate typically takes about 3 to 6 months from filing to the issuance of Letters Testamentary. The timeline depends on how quickly all distributees sign waivers, whether the will is “self-proving,” and the current docket at the Riverhead courthouse. When every heir consents and there are no objections, the court can enter a decree admitting the will on the return date, and Letters issue shortly after. Contested matters take considerably longer — see our contested probate page.
4. What does it cost to probate an estate in Suffolk County?
There are two cost categories. First, the court filing fee is graduated by the value of the estate under SCPA §2402 — it scales with the size of the estate, so confirm the exact amount with the court or your attorney rather than relying on a flat figure. Second, attorney’s fees for a straightforward, uncontested probate generally fall in the range of $3,000 to $10,000, depending on estate complexity, the number of distributees, and whether disputes arise.
5. Can the executor act before probate is finished?
Yes. If estate matters are urgent — for example, a Long Island home that needs to be secured, insured, or sold, or bills that must be paid — the court can grant Preliminary Letters Testamentary under SCPA §1412. These give the nominated executor interim authority to manage and protect estate assets while the full probate petition is still pending. Preliminary Letters are a common tool when distributees are slow to sign waivers or a citation must be served.
6. What are the executor’s duties once Letters issue?
After receiving Letters Testamentary, the executor must collect and safeguard the estate’s assets, pay valid debts, expenses, and taxes, and then distribute what remains to the beneficiaries named in the will. This includes marshaling Suffolk County real property, bank and brokerage accounts, and personal property, and keeping accurate records throughout. Our executor duties page explains the fiduciary’s responsibilities and personal liability in full.
7. Is there a simpler process for a small estate?
Yes. When the decedent’s personal property is modest, New York offers Voluntary Administration under SCPA Article 13 — a streamlined affidavit-based procedure that avoids full probate. A key limitation for Long Island families: real property is generally excluded from this process, so an estate that includes a Suffolk County house usually cannot use it. Learn more on our small estate affidavit page.
8. Will the estate owe New York estate tax?
For deaths in 2026, New York provides an estate tax exclusion of $7,350,000. Most Long Island estates fall below this threshold and owe no New York estate tax. Be aware of New York’s “cliff”: if the taxable estate exceeds 105% of the exclusion — $7,717,500 — the exclusion is lost entirely and tax applies to the whole estate, not just the excess. Estates near that line should plan carefully with counsel and consult the New York State Department of Taxation and Finance.
9. What happens if someone challenges the will?
If a distributee or other interested party files objections, the matter becomes a contested probate. The Surrogate’s Court will address the objections — common grounds include lack of due execution, lack of testamentary capacity, undue influence, or fraud — before deciding whether to admit the will. Contested proceedings involve discovery (including SCPA §1404 examinations of the will’s witnesses) and can extend the timeline well beyond the usual months. See contested probate for what to expect.
10. Do I need a Suffolk County probate attorney?
While New York does not strictly require an attorney, probate involves precise statutory filings, jurisdiction over heirs, creditor and tax obligations, and fiduciary liability — and mistakes can be costly. A Long Island probate attorney handles the petition, secures waivers or serves citations, obtains Letters, and guides the executor through distribution.
