New Hampshire Rules of Evidence for Civil Litigation

Overview: The New Hampshire Evidence Framework

New Hampshire's rules of evidence are codified in the New Hampshire Rules of Evidence (N.H. R. Evid.), adopted in 2015. These rules closely follow the Federal Rules of Evidence (FRE) model, making them familiar to attorneys who regularly practice in federal court. However, New Hampshire is not bound by federal precedent on evidence matters, and state courts have developed some distinct interpretations and applications unique to New Hampshire jurisprudence.

The N.H. R. Evid. consists of 11 articles covering evidence generally, relevance, witnesses, hearsay, the best evidence rule, and miscellaneous provisions. Understanding that New Hampshire tracks the federal framework is critical—decisions interpreting the FRE often persuade New Hampshire courts, but state law ultimately governs.

Relevance: The Foundation of Admissibility

N.H. R. Evid. 401 defines relevant evidence as evidence having any tendency to make a fact of consequence more or less probable than it would be without the evidence. This is a low threshold. Nearly any evidence touching on a material issue clears the relevance hurdle.

However, relevance alone doesn't guarantee admission. N.H. R. Evid. 403 permits a court to exclude relevant evidence if its probative value is substantially outweighed by a danger of unfair prejudice, confusion, misleading the jury, undue delay, waste of time, or needless presentation of cumulative evidence. This balancing test gives judges discretion to manage trial efficiency and fairness.

In practice, 403 objections often arise when:

Gruesome photographs are offered when less inflammatory alternatives exist

Multiple expert witnesses address redundant theories

Time-intensive evidence adds minimal probative weight

Evidence appeals to bias rather than logic

Courts apply 403 sparingly—the burden is on the party challenging admissibility to demonstrate that probative value is substantially outweighed by danger.

Character Evidence in Civil Cases

New Hampshire follows the Federal Rules' cautious approach to character evidence. N.H. R. Evid. 404(a) generally prohibits character evidence offered to prove that a person acted in accordance with that character on a particular occasion.

Exceptions in civil cases include:

Character evidence is admissible when character is a material element of a claim or defense (e.g., negligent hiring cases where the defendant's hiring practices are directly at issue)

Evidence of a person's habit or routine practice is admissible under N.H. R. Evid. 406 to show conforming conduct on a particular occasion

In defamation cases, the plaintiff's character for the trait that was defamed may be relevant to damages

N.H. R. Evid. 404(b) permits evidence of other acts for purposes such as proving motive, opportunity, common scheme, plan, or lack of accident—but New Hampshire courts require clear notice and careful instruction to the jury that such evidence is not admitted for character purposes.

Evidence of subsequent remedial measures is governed separately (see below).

Hearsay: Definition and Core Exceptions

N.H. R. Evid. 801 defines hearsay as a statement the declarant makes at a time other than while testifying at trial, and a party offers in evidence to prove the truth of the matter asserted. Critically, this definition turns on whether the statement is offered for its truth. Non-hearsay uses (credibility, state of mind, impeachment) are unaffected.

New Hampshire recognizes that the declarant's out-of-court statement on the witness stand is not hearsay under N.H. R. Evid. 801(d)(1)—this covers prior statements by testifying witnesses, including inconsistent statements and prior identification testimony.

Key Hearsay Exceptions (N.H. R. Evid. 803 & 804)

Present Sense Impression (803(1)): A statement describing or explaining an event or condition, made while the declarant was perceiving the event or immediately thereafter. Example: "There's a fire on the roof!" shouted as flames become visible.

Excited Utterance (803(2)): A statement relating to a startling event, made while under stress from excitement or nervous tension caused by the event. This exception survives longer after the event than present sense impression and doesn't require the declarant to be perceiving the event, only reacting to it emotionally.

Then-Existing Mental, Emotional, or Physical Condition (803(3)): Statements of the declarant's current state of mind, emotion, sensation, or physical condition. This exception does not extend to statements of memory or belief about past events. Example: "My knee hurts" is admissible; "My knee was injured in the accident" is not, because it asserts a past fact, not a present condition.

Business Records (803(6)): Records of an act, event, condition, opinion, or diagnosis made at or near the time of the event by someone with knowledge, if creating the record was part of a regular business practice. New Hampshire requires:

Authentication by a foundation witness with personal knowledge of the record's creation

Testimony that the business made the record as part of its regular activity

Testimony that it was the business's practice to make such records

The witness's explicit statement that the circumstances indicate trustworthiness (or lack thereof)

A common pitfall: failing to establish that the source of information and the method of preparation inspire confidence. Courts in New Hampshire take this seriously—conclusory statements ("our records are reliable") won't suffice.

Public Records and Reports (803(8)): Records, reports, and data compilations of public agencies setting forth factual findings from investigations or activities authorized by law. However, police investigative reports containing witness statements may be excluded under the Confrontation Clause in criminal cases, and New Hampshire courts scrutinize them in civil cases as well.

Statements Against Interest (804(b)(3)): A statement that was at the time of making so contrary to the declarant's pecuniary, proprietary, or penal interest, or so tended to subject the declarant to civil or criminal liability, that a reasonable person in the declarant's position would not have made it unless believing it to be true. The declarant must be unavailable.

Prior Testimony (804(b)(1)): Testimony given as a witness at another hearing, proceeding, or deposition if the party against whom the evidence is offered had an opportunity and similar motive to develop the testimony by examination or cross-examination.

Residual Exception (807): A statement not covered by other exceptions, but offered as evidence of a material fact, where the statement has circumstantial guarantees of trustworthiness equivalent to those of categorical exceptions, the declarant is unavailable, and the statement's admission will serve the interests of justice. New Hampshire courts rarely invoke this exception and require a strong showing of reliability and necessity.

New Hampshire-Specific Considerations

New Hampshire has not created hearsay exceptions unique to state law that diverge dramatically from the Federal Rules. However, state courts have occasionally applied exceptions more flexibly. For example, statements in journals or diaries may receive favorable treatment under the business records or excited utterance exceptions in some contexts, particularly when the alternative is complete loss of evidence.

Authentication of Evidence

N.H. R. Evid. 901(a) requires that evidence be authenticated or identified before admission. The proponent must produce evidence sufficient to support a finding that the matter is what the proponent claims it to be.

Methods of authentication include:

Testimony of a witness with knowledge (N.H. R. Evid. 901(b)(1)): "I took this photograph" or "This is my signature"

Non-expert opinion on handwriting (N.H. R. Evid. 901(b)(2)): A person familiar with the writing of the alleged author may testify to authenticity

Comparison by the trier of fact (N.H. R. Evid. 901(b)(3)): Handwriting, voice, or other writing samples can be compared to authenticated specimens

Distinctive characteristics and circumstances (N.H. R. Evid. 901(b)(4)): The appearance, contents, substance, internal patterns, or other distinctive characteristics of an item, combined with circumstantial evidence, may authenticate. Example: An email bearing the sender's known email address, containing specific details only that person would know, sent to the recipient's address at a time consistent with business communications.

Public records authentication (N.H. R. Evid. 901(b)(7)): An official publication or a copy certified as correct by the custodian may authenticate

Ancient documents (N.H. R. Evid. 901(b)(8)): Documents at least 20 years old, in condition consistent with age, and from proper custody are presumptively authentic

Electronic evidence requires careful authentication. In New Hampshire civil cases, counsel must establish:

The source and means of creation of the electronic data

That the electronic evidence is what it purports to be (metadata, timestamps, or expert testimony on digital forensics may be necessary)

That the evidence was not altered, corrupted, or compromised

Social media posts, text messages, and emails must be authenticated by testimony that the sender composed and sent the message or that it came from a recognizable account holder. Screenshots alone are risky; consider preserving electronic records through forensic methods or certified exports when stakes are high.

Best Evidence Rule

N.H. R. Evid. 1002 requires that to prove the content of a writing, recording, or photograph, the original must be produced unless an exception applies.

Exceptions include:

A duplicate is admissible to the same extent as the original unless a question is raised about authenticity or circumstances suggest unfairness (N.H. R. Evid. 1003)

Originals are excused if lost or destroyed without bad faith (N.H. R. Evid. 1004)

The writing is not closely related to controlling issues (N.H. R. Evid. 1004(b))

Public records are certified copies (N.H. R. Evid. 1005)

In practice, electronic documents pose interesting questions. A PDF saved to a hard drive, printed, or transmitted via email is typically deemed a duplicate admissible under 1003. However, if the electronic document's metadata or digital integrity is in dispute, the party offering the evidence should be prepared to explain the chain of custody and production method.

The best evidence rule applies to writings and recordings, not to photographs or electronic evidence per se—though authenticity must still be established.

Expert Testimony: The Daubert Standard

New Hampshire has formally adopted the Daubert standard, as established in Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993). Under N.H. R. Evid. 702, an expert witness may testify if the expert's scientific, technical, or specialized knowledge will help the trier of fact understand evidence or determine a fact in issue, provided:

The testimony is based on sufficient facts or data

The testimony is the product of reliable principles and methods

The witness has reliably applied the principles and methods to the facts

The Daubert Gatekeeping Function

New Hampshire courts serve as gatekeepers. The trial judge must assess whether the expert's methodology is sound, whether it has been tested, whether error rates are known, whether peer review has occurred, and whether the method has general acceptance in the relevant scientific community. The judge is not bound by expert agreement on reliability—the court makes the determination independently.

Key Daubert factors include:
1. Whether the technique can be and has been tested
2. Whether the technique has been subjected to peer review and publication
3. The technique's known or potential error rate and standards controlling the technique's operation
4. Whether the technique has achieved general acceptance in the relevant scientific community
5. Whether the expert's testimony is based on an adequate foundation and reliable methodology

Qualifying an expert in New Hampshire:

Establish credentials (education, experience, training, publications, prior expert testimony)

Establish personal knowledge of the facts underlying the opinion

Establish the methodology used to form the opinion

Establish that the methodology is reliable and appropriate to the case facts

Elicit clear, non-speculative opinions within the expert's area of expertise

Common pitfalls:

Relying solely on "experience" without demonstrating that experience is reliably applied to the specific question

Offering opinions outside the expert's area of knowledge or education

Failing to explain the methodology with sufficient detail for cross-examination

Using industry custom or standard practice without establishing that the standard itself is reliable

Unlike some jurisdictions, New Hampshire does not require advance notice of expert opinions in all civil cases, though discovery rules may require disclosure. Civil Rules of Procedure govern discovery; check whether a specific rule or local rule in your court applies.

Lay Witness Opinion Testimony

N.H. R. Evid. 701 permits a lay witness to testify in the form of an opinion if it is:

Rationally based on the witness's perception

Helpful to clearly understand the witness's testimony or determine a fact in issue

Not based on scientific, technical, or specialized knowledge

Lay witnesses may offer opinions on matters such as:

Speed and distance ("The car was going about 40 miles per hour")

Emotional state ("She seemed upset")

Handwriting ("That looks like John's signature")

Bodily conditions ("She appeared injured" or "He looked intoxicated")

Collective facts that defy precise description ("The intersection was chaotic")

The boundary between lay and expert opinion is context-dependent. New Hampshire courts apply Rule 701 sensibly—if a witness is testifying based on everyday experience and perception, not scientific methodology, the opinion is likely admissible even if it touches on matters an expert could address.

Privileges

New Hampshire recognizes several evidentiary privileges under N.H. R. Evid. Article V:

Attorney-Client Privilege (N.H. R. Evid. 502): Protects confidential communications between attorney and client made for the purpose of providing legal advice. The privilege applies to:

Oral and written communications

Information the client provides to the attorney

Legal advice the attorney provides to the client

Work product (documents prepared in anticipation of litigation)

The privilege may be waived by disclosure, failure to assert it, or if a third party is present (with limited exceptions for agents assisting the attorney).

Spousal Privilege (N.H. R. Evid. 504): A spouse cannot be compelled to testify against the other spouse about confidential communications made during the marriage. New Hampshire protects both the confidential communication and, in some contexts, the fact of the marriage itself. The privilege survives divorce unless waived.

Physician-Patient Privilege (N.H. R. Evid. 503): A patient may refuse to disclose, and the physician cannot disclose, communications between patient and physician made in the course of treatment or examination. The privilege extends to information acquired by the physician in treating the patient.

Psychotherapist-Patient Privilege (N.H. R. Evid. 503): Similar protections apply to psychotherapists and mental health counselors. This privilege is frequently asserted in personal injury and employment cases.

Clergy-Penitent Privilege (N.H. R. Evid. 505): A person may refuse to disclose a confidential communication made to a clergyman in the clergyman's professional capacity.

Journalist Privilege: New Hampshire recognizes a limited journalist privilege by case law, though it is not codified in the Rules of Evidence. Courts balance the journalist's interest in protecting sources against the party's need for the information.

Privilege Against Self-Incrimination: Not a testimonial privilege per se, but a witness may refuse to answer questions on the grounds that the answers would be self-incriminating in a criminal matter.

Privileges must be asserted by the holder; failure to object waives them. When responding to discovery requests, use privilege logs to identify withheld materials and the privilege claimed.

Judicial Notice

N.H. R. Evid. 201 permits the trial court to take judicial notice of adjudicative facts (facts about the parties and their activities, properties, and liabilities). The court may notice facts that are not reasonably subject to dispute because they are:

Generally known within the trial community

Capable of accurate and ready determination by resort to sources whose accuracy cannot reasonably be questioned

Examples of facts New Hampshire courts have judicially noticed:

The location and boundaries of cities and highways

Historical facts and dates

Court records (the court's own files)

Customary business practices or scientific facts capable of verification

Judicial notice of adjudicative facts is appropriate in civil cases; notice of legislative facts (broader principles applicable to the law or policy) is less restricted but subject to careful scrutiny.

Critical rule: A party may request an instruction that the jury is permitted (but not required) to accept the judicially noticed fact as conclusive (N.H. R. Evid. 201(f)). If a party requests, the court must instruct the jury that it may, but is not required to, accept the noticed fact as true. This is essential for preserving a party's objection on appeal.

Impeachment: Attacking Witness Credibility

Prior Inconsistent Statements (N.H. R. Evid. 613): A witness may be impeached with a prior inconsistent statement. The examining attorney should:
1. Direct the witness's attention to the statement
2. Describe its substance (or show it to the witness)
3. Ask the
