Subpoenas and Discovery Demands in Estate Disputes

By Juan Lozano|Published April 11, 2026

When an estate dispute escalates to litigation, both sides need access to documents, information, and testimony to build their case. Discovery—the formal process of exchanging evidence—is a key part of contested estate litigation. Subpoenas and discovery demands are the tools used to compel the other side (and sometimes third parties) to produce relevant information. Understanding your rights and obligations regarding subpoenas and discovery demands is critical to protecting your interests and complying with court orders.

This guide explains what subpoenas and discovery demands are, when they're used in estate disputes, what you must produce, and what happens if you fail to comply.

Understanding Subpoenas in Surrogate's Court

A subpoena is a court order requiring a person to appear at a deposition or trial to testify, or to produce documents relevant to a legal proceeding. In estate disputes, subpoenas are commonly used to obtain testimony from witnesses who have relevant information, such as the decedent's caregivers, healthcare providers, financial advisors, or family members. A subpoena can also require the person served to produce documents, such as medical records, financial statements, or communications.

Under CPLR (Civil Practice Law and Rules) Article 23, which applies to surrogate's court proceedings, a subpoena must be issued by the court or an authorized attorney. It must clearly state who must comply, what action is required (appearance at deposition, trial, or production of documents), and the deadline for compliance. A subpoena must be personally served on the person it's directed to, and that person generally must be paid a witness fee and mileage reimbursement.

Discovery Demands: Interrogatories, Document Requests, and Admissions

While subpoenas are directed at parties and third parties, discovery demands are requests from one party to another for information and documents. The three main types of discovery demands are:

  • Interrogatories — written questions the opposing party must answer under oath
  • Requests for production of documents — which require the opposing party to turn over relevant documents
  • Requests for admissions — which ask the opposing party to admit or deny specific statements (admissions simplify the facts that don't need to be proven at trial)

Discovery demands must follow the rules set forth in CPLR Articles 3130-3133. They must be proportional to the needs of the case and not unduly burdensome. A party cannot request information protected by attorney-client privilege or work product protection. Interrogatories are limited in number unless the parties agree otherwise, typically capped at 20 without court permission. Document requests should be specific enough to allow the other party to understand what's being requested.

What Types of Documents Must Be Produced in Estate Disputes

In contested estates, the scope of discoverable documents can be broad. Common document requests include:

  • The original will and any drafts or codicils
  • Medical records of the decedent, particularly relevant to competency or capacity
  • Financial records of the decedent, including bank statements, investments, and property records
  • Communications between the decedent and the parties (emails, letters, texts)
  • Communications between the executor or administrator and other parties
  • Accounting records and estate administration documents
  • Documents related to the decedent's long-term care or support arrangements

If the dispute involves an allegation of undue influence, the scope of discovery expands to include the beneficiary's financial dealings with the decedent, communications reflecting the nature of their relationship, evidence of the beneficiary's isolation of the decedent from family, and information about the beneficiary's financial circumstances. The idea behind broad discovery in estate disputes is that all relevant information should be on the table so the dispute can be fairly and accurately resolved.

Your Obligations When You Receive a Subpoena or Discovery Demand

When you receive a subpoena, deposition notice, or discovery demand, you have a legal obligation to comply. If you're required to appear for a deposition, you must appear at the date, time, and location specified, unless the deadline is extended by agreement or court order. If you're required to produce documents, you must produce them within the deadline specified, typically 20 days unless the parties agree to a different timeframe or the court orders otherwise.

If you cannot fully comply with a discovery demand, you must provide a written response explaining the reasons for non-compliance. For example, if you're requested to produce documents that are covered by attorney-client privilege, you should not produce them but instead provide a privilege log describing the documents and explaining why they're privileged. Ignoring a subpoena or discovery demand can result in sanctions, including contempt of court charges, adverse inferences (the court may assume your non-produced documents support the other side's position), or even dismissal of your case or judgment against you.

Protecting Your Rights: Objections and Protective Orders

You have the right to object to subpoenas and discovery demands if they're unduly burdensome, seek privileged information, or are otherwise improper. Common objections include: lack of relevance, undue burden, attorney-client privilege, work product protection, or violation of privacy. You must state your objection in writing and provide specific reasons. Simply ignoring a demand is not a valid objection.

If you believe a subpoena or discovery demand is particularly onerous, you can petition the court for a protective order limiting the scope of discovery, the time for compliance, or the manner of production. For example, if a discovery request seeks millions of pages of documents, you might request a protective order requiring the other side to narrow the request. A protective order requires demonstrating to the court that the discovery as requested would be unduly burdensome.
