Massachusetts Civil Discovery Rules and Procedures

Jurisdiction: Massachusetts

Massachusetts Civil Discovery Rules and Procedures

Massachusetts civil discovery is governed by the Massachusetts Rules of Civil Procedure (Mass. R. Civ. P.), which largely track the Federal Rules of Civil Procedure but contain important differences. Understanding these distinctions is critical for attorneys and pro se litigants filing suit in Massachusetts state courts.

Mandatory Initial Disclosures

Massachusetts does require mandatory initial disclosures, though they are more limited than federal requirements. Under Mass. R. Civ. P. 26(a)(1), parties must make initial disclosures without awaiting a discovery request, unless the parties agree otherwise or the court orders otherwise.

Required disclosures include:

  • The name, address, and telephone number of each person likely to have discoverable information, organized by subject matter

  • A description of the location and general nature of documents, ESI, and tangible things in the disclosing party's possession, custody, or control

  • A calculation of damages claimed, including the methodology and documents supporting the calculation

  • Any insurance policies or similar arrangements that may satisfy a judgment

  • An authorization for inspection of documents and physical inspection of premises
  • Timing: Initial disclosures must be made within 14 days after the parties have conferred as required by Mass. R. Civ. P. 26(f), or within 14 days of service of summons and complaint if no Rule 26(f) conference occurs. This conference—called the "discovery planning conference" or "Rule 26(f) conference"—is mandatory unless exempted by local rule or court order.

    Critical distinction from federal practice: Massachusetts does not automatically include expert disclosures in the initial disclosure requirement. Expert information is handled separately under Mass. R. Civ. P. 26(b)(4).

    Interrogatories

    Interrogatories are written questions requiring written responses under oath. Mass. R. Civ. P. 33 governs this discovery method.

    Numerical limits: A party may serve no more than 25 interrogatories on any other party, including all subparts, without court order or stipulation. This 25-interrogatory ceiling is crucial—subparts count toward the limit. Compound interrogatories asking multiple questions are disfavored and courts often count each separate question.

    Format requirements:

  • Interrogatories must be clearly numbered

  • Each interrogatory must be concise and not compound, unless otherwise authorized by the court

  • They must relate to matters within the scope of permissible discovery under Mass. R. Civ. P. 26(b)

  • Requests for narrative responses or opinions are permitted but must be carefully drafted to avoid objections
  • Time to respond: A responding party has 30 days from service to respond to interrogatories, unless the parties agree otherwise or the court orders a different period.

    Objections: Responses may be omitted only if the party states with specificity the grounds for objection and, if applicable, states that it is making no other response. Common objections in Massachusetts practice include:

  • Lack of relevance or proportionality

  • Seeking information protected by attorney-client privilege or work product doctrine

  • Seeking expert information (typically deferred under Rule 26(b)(4))

  • Requesting information equally available to the requesting party

  • Unduly burdensome
  • The party making an objection must still provide any responsive information not subject to the objection.

    Requests for Production of Documents

    Mass. R. Civ. P. 34 governs requests for production of documents, ESI, and tangible things.

    Scope: Any party may request production of documents and ESI from any other party. The scope includes:

  • Documents and tangible things in the responding party's possession, custody, or control

  • Electronically stored information (ESI)

  • Permission to inspect and copy documents and ESI

  • Permission to enter land or other property for inspection, measurement, or testing
  • Format requirements:

  • Requests must describe items with reasonable particularity

  • Each request should be separately numbered

  • Requests may be phrased in the alternative or as a series of requests

  • The requesting party should specify the format for production of ESI (e.g., native format, PDF, searchable format)
  • Time to respond: A responding party has 30 days from service to respond unless the parties agree otherwise or the court orders otherwise.

    ESI considerations: Massachusetts recognizes ESI as a distinct category of discoverable material. Mass. R. Civ. P. 34(b) allows parties to request ESI and specify the form of production. Important ESI-specific issues include:

  • Format disputes: Parties should address ESI format during the Rule 26(f) conference. Common disputes involve native format (with metadata) versus PDF (easier to review but no metadata)

  • Metadata: Unless otherwise specified, parties must produce ESI in the form in which it is ordinarily maintained or in a form that is reasonably usable

  • Inaccessible ESI: A party need not provide ESI that is not reasonably accessible because of undue burden or cost, but must describe what was not produced and why

  • Clawback agreements: Mass. R. Civ. P. 502(b)(5) permits parties to enter agreements regarding inadvertent production of privileged materials
  • Objections may be asserted on grounds of privilege, work product, undue burden, or lack of relevance. A party objecting to ESI production must state whether it is withholding documents on the basis of the objection.

    Requests for Admission

    Mass. R. Civ. P. 36 permits requests for admission of facts, the application of law to fact, and the authenticity of documents.

    Numerical limits: Unlike interrogatories, Mass. R. Civ. P. 36 does not impose a numerical limit on requests for admission. However, courts may limit the number through a protective order or case management order if the number becomes excessive or burdensome.

    Time to respond: A responding party has 30 days from service to admit or deny each request, or state that it cannot admit or deny on the basis of information available.

    Consequences of failure to respond: Any matter for which an admission is not made is deemed admitted unless the party serving the request failed to follow proper service procedures or the court grants relief. This automatic deeming provision is harsh and frequently litigated. Once deemed admitted, the matter is established for purposes of the action and need not be proved.

    Objections: A party may object to a request for admission on grounds of:

  • Lack of relevance

  • Privilege or work product protection

  • Undue burden or expense

  • Vagueness or ambiguity of the request
  • Objections must be stated specifically and concisely. Evasive or incomplete responses may be treated as admissions.

    Practical tip: Always respond to requests for admission, even if only to state that you cannot admit or deny based on available information. Failure to respond within 30 days results in automatic admission, which is extremely difficult to undo.

    Depositions

    Depositions are oral examinations of parties and non-parties, conducted under oath. Mass. R. Civ. P. 30 and 31 govern depositions.

    Number allowed: A party may take no more than ten depositions without court order or agreement of the parties. This limit includes depositions of both parties and non-parties. A deposition lasting more than one day counts as multiple depositions if it extends beyond the time limitations in Mass. R. Civ. P. 30(d).

    Duration limits:

  • A deposition may not last more than seven hours unless otherwise stipulated or ordered by the court

  • The party seeking to extend a deposition beyond seven hours must seek a protective order or obtain written agreement

  • The deposition may be extended if the deposing attorney demonstrates good cause for additional time
  • Notice requirements:

  • The taking attorney must provide at least ten business days' notice to the deponent and all other parties

  • Notice must specify the date, time, and location of the deposition

  • For non-parties, notice must comply with subpoena requirements and allow adequate time for service

  • A party may designate a representative (usually counsel) to attend on its behalf
  • Who can be deposed:

  • Any party to the action

  • Non-parties with knowledge of relevant facts (via subpoena)

  • Corporate representatives (designated under Mass. R. Civ. P. 30(b)(6))
  • Corporate/organizational depositions: A party may require an organization to designate and produce a representative or representatives to testify regarding designated topics. The organization must prepare its representative(s) to testify fully about the subject matter.

    Use at trial:

  • Depositions may be used for impeachment of any witness

  • Depositions of unavailable parties may be used as evidence at trial under Mass. R. Civ. P. 32(a)

  • "Unavailable" includes parties residing more than 100 miles from the trial venue, incarcerated parties, and parties whose attendance cannot be compelled
  • Recording: Depositions must be recorded unless the parties agree otherwise. A court reporter or video recording is standard.

    Physical and Mental Examinations

    Mass. R. Civ. P. 35 permits examinations of the physical or mental condition of a party or, in limited circumstances, a non-party.

    When allowed: Physical or mental examination is permitted only when the condition is in controversy and when the requesting party has good cause for the examination.

    Who can request: Only a party to the action may request an examination. The requesting party must establish:

  • The condition sought to be examined is genuinely in controversy

  • Good cause exists for the particular examination

  • The examination is not unduly burdensome or oppressive
  • Good cause standard: Massachusetts courts have interpreted "good cause" to require a showing that the examination is necessary and that less intrusive discovery methods are insufficient. A party claiming emotional distress or back injury must demonstrate that the examination is relevant and necessary.

    What's required:

  • A written motion showing good cause must be filed and served

  • The motion must specify the time, place, manner, and conditions of the examination

  • The examining physician must have qualifications relevant to the condition in question

  • The party to be examined has the right to have an observer present

  • The examining physician must provide a written report of findings
  • Report exchange: Upon request, the party examined is entitled to receive a copy of the medical examiner's written report. In turn, that party must provide any medical reports it has obtained regarding the same condition.

    Subpoenas for Non-Parties

    Mass. R. Civ. P. 45 governs subpoenas to compel testimony and production of documents from non-parties.

    How to issue: A subpoena is issued by the clerk of the court or by an attorney who is authorized to practice in the jurisdiction. No court order is required to issue a subpoena.

    Geographic limits: A non-party may be required to:

  • Testify within 100 miles of the place where the non-party resides, works, or regularly conducts business

  • Produce documents or permit inspection within the same geographic range

  • A subpoena requiring travel beyond 100 miles is permitted only if the non-party agrees or the court orders otherwise
  • Compliance requirements:

  • The subpoena must be served personally on the non-party

  • Service must occur at least ten business days before the deposition or hearing date

  • The subpoena must include a statement of the non-party's rights and obligations

  • If the subpoena requires production of documents, it must describe the documents with reasonable particularity
  • Cost reimbursement: If a non-party must travel more than 100 miles or incurs significant expense, the subpoenaing party must offer to reimburse the non-party's reasonable travel expenses unless the non-party agrees otherwise.

    Objections: A non-party may object to a subpoena within ten business days of service by filing a motion to quash or limit the subpoena. The non-party may object on grounds of undue burden, privilege, or lack of relevance.

    Expert Discovery

    Mass. R. Civ. P. 26(b)(4) governs discovery of expert information and opinions.

    Disclosure requirements: A party must disclose:

  • The identity of any expert witness the party intends to call at trial

  • A written report prepared by the expert containing:

  • - A statement of the expert's qualifications
    - A detailed statement of the facts and data underlying the expert's opinions
    - A statement of the opinions to be rendered and the basis therefor
    - An explanation of the methodologies used
    - Identification of publications authored by the expert
    - A statement of the expert's compensation for the case
    - A list of other cases in which the expert has testified in the prior four years

    Timing: Expert disclosures must be made:

  • As directed by the court's scheduling order, or

  • If no scheduling order exists, at least 30 days before trial (or as otherwise agreed by the parties)
  • Timing for rebuttal experts: Rebuttal expert disclosures must be made within 14 days of receipt of the other party's expert disclosure, unless the court orders otherwise.

    Deposing experts: A party may depose an expert after receiving the expert's written report. The expert deposition counts against the party's ten-deposition limit unless the court permits additional depositions. Expert depositions are frequently used to explore the basis of opinions and challenge methodologies.

    Work product protection: A party's attorney work product—attorney mental impressions, legal conclusions, and litigation strategy—is protected from discovery even with respect to expert discovery. Drafts of expert reports and attorney communications with experts may be protected.

    Scope of Discovery

    Discoverable information: Mass. R. Civ. P. 26(b)(1) defines the scope of discovery broadly. Parties may discover any information that is relevant to a claim or defense and is not subject to privilege or work product protection.

    Relevance standard: Information is relevant if it has any bearing on a fact of consequence or would be helpful in resolving a factual dispute. Massachusetts courts apply a broad relevance standard, permitting discovery of information that is not itself admissible if it is reasonably calculated to lead to the discovery of admissible information.

    Proportionality: Even if discoverable, information need not be produced if the burden or expense of producing it substantially outweighs its likely benefit. Factors considered include:

  • The importance of the issues in the case

  • The amount in controversy

  • The parties' relative access to information

  • The parties' resources and financial ability to conduct discovery

  • The importance of the discovery to the case management and adjudication
  • This proportionality limitation became more prominent in recent amendments to the Massachusetts rules and provides a ground for objecting to overly burdensome discovery requests.

    Privileges and Work Product

    Attorney-client privilege: Communications between a client and attorney made for the purpose of obtaining legal advice are protected from discovery. This privilege covers:

  • Communications regarding pending or anticipated litigation

  • Advice given in confidence

  • Factual information provided by the client for the purpose of obtaining legal advice
  • Work product doctrine: Mass. R. Civ. P. 26(b)(3) protects attorney work product—documents and materials prepared in anticipation of litigation. This protection covers:

  • Attorney mental impressions, conclusions, and legal theories

  • Litigation strategy and case evaluation

  • Drafts of pleadings, motions, and discovery responses

  • Notes of interviews with witnesses conducted by attorneys or agents
  • Exceptions: Work product protection may be overcome upon a showing of substantial need for the material and inability to obtain it through other means without undue hardship.

    Privilege logs: When a party withholds documents on the basis of privilege, it must provide a privilege log describing each withheld document with sufficient detail to allow the opposing party and the court to assess the validity of the privilege claim. The log should include:

  • Document identification (date, author, recipients)

  • General description of the document's contents

  • The specific privilege being asserted

  • The reason the privilege applies
  • Inadvertent disclosure of privileged material: Mass. R. Civ. P. 502(b)(5) allows the parties to enter a clawback agreement providing that inadvertent production of privileged material does not waive privilege. Without such an agreement, inadvertent disclosure may result in waiver of privilege, though the court may order return of the materials and continued protection.

    Meet and Confer Requirements

    Mandatory conference: Before filing any motion to compel discovery, a party must make a good faith effort to confer with the other party regarding the dispute. This requirement is codified in Mass. R. Civ. P. 26(f) and is enforced strictly by Massachusetts courts.

    Conference process:

  • The discovering party should send a letter or email to opposing counsel explaining the discovery dispute and proposing a solution

  • The parties should discuss the matter in an attempt to reach agreement

  • If agreement cannot be reached, the discovering party may file a motion to compel with an affidavit or certification that good faith efforts to confer were made
  • Failure to meet and confer: Failure to comply with this requirement may result in:

  • Denial of the motion to compel

  • Award of sanctions against the non-compliant party

  • Requirement that the parties participate in a conference with the court before the motion is heard
  • This requirement is designed to reduce unnecessary court involvement and encourage cooperative discovery.

    Discovery Cutoffs and Timeline

    Discovery close date: Discovery must close by a date set in the court's scheduling order or, if no order exists, by agreement of the parties. Typical discovery periods range from 10 to 18 months after commencement of the action.

    Relation to trial: Discovery typically closes:

  • 60 days before the trial date, unless the court orders otherwise, or

  • As specified in the scheduling order
  • Extending discovery: A party may
