Nassau County Surrogate's Court form basics

Nassau County Surrogate's Court handles estate matters for people who lived in Nassau County, including probate, administration, small estates, guardianship matters handled by Surrogate's Court, accountings, and related estate applications.

Court form names are not always written the way people naturally ask questions. A person may search for estate forms, letters of administration, probate papers, or small estate affidavit when what they really need is a packet of related documents that work together.

This guide is general information, not legal advice. Court staff can provide procedural information, but they cannot tell you what legal strategy to choose.

Quick answer: which form category usually fits the situation?

The most searched Nassau form categories

Probate is used when the decedent left a will. The court reviews the will and, if the requirements are met, issues Letters Testamentary to the executor named in the will. Users usually need the Petition for Probate, the original will, a certified death certificate, information about distributees, waivers or citations, and supporting affidavits.

Administration is used when the decedent did not leave a will, or when there is no will being admitted to probate. The court may issue Letters of Administration to an eligible distributee. A typical packet asks for the death certificate, family relationship information, asset information, funeral information, waivers and consents when available, and citation or service documents when required.

New York calls a small estate a voluntary administration. It may be available when the decedent had $50,000 or less in personal property. Personal property includes things like bank accounts, vehicles, and personal belongings. It does not include real property such as a house, land, or condominium.

Surrogate's Court guardianship is different from many Family Court searches. Surrogate's Court may handle guardianship of a child under Article 17, including guardianship of a child's person or property, and Article 17-A guardianship for an intellectually or developmentally disabled person.

Search interest for ET-117 usually comes from real estate closings. New York's estate tax lien can affect real property located in New York. The Form ET-117 release of lien is often paired with ET-85, ET-30, or ET-706 depending on the estate and timing.

What to gather before opening the Forms page

  • Decedent's full legal name, date of death, and county of residence at death.
  • Certified death certificate.
  • Original will and codicils, if any. Do not remove staples from the original will.
  • Names, addresses, and relationships of surviving spouse, children, parents, siblings, and other distributees.
  • Asset list, including bank accounts, vehicles, real estate, co-op interests, and personal property.
  • Estimated estate value for filing-fee purposes.
  • Funeral bill or funeral payment information.
  • Deed, tax bill, section/block/lot, or co-op details if real property is involved.
  • Contact information for any person who may need notice or service.

Common filing mistakes

The most common delays are usually missing people, incomplete family trees, wrong county venue, missing death certificates, unsigned waivers, unclear asset values, or form packets that mix probate and administration documents.

If the decedent owned property in Nassau County but lived somewhere else, venue and ancillary filing questions may need review before choosing the packet.

Facts only. No legal-advice questions.

Keystone Pinnacle Pro is built to ask factual questions: names, dates, addresses, family relationships, assets, debts, notices, signatures, and filing details. It does not ask users to choose legal strategy, interpret legal rights, decide who should object, or answer questions that require legal advice. If a question turns on legal judgment, the user should confirm requirements with the Surrogate's Court or speak with an attorney.
