The New Hampshire Rules of Evidence decide what a judge or jury is allowed to hear in a state courtroom, from a routine small-claims hearing up through a felony trial. They are modeled on the Federal Rules of Evidence and cover relevance, hearsay, privilege, witness qualifications, impeachment, and authentication. If you are preparing for a hearing, sitting for a deposition, or trying to understand a ruling that already went against you, these are the rules doing the work.
Where the Rules Apply
Rule 1101 sets the scope. The rules apply to all proceedings in the Supreme Court, Superior Court, and Circuit Court, including the District and Probate Divisions, in both civil and criminal cases, unless the New Hampshire Constitution, a statute, or the rules themselves say otherwise.1New Hampshire Judicial Branch. New Hampshire Rules of Evidence – Rule 1101 Applicability of Rules
Several proceedings are exempt because their purpose is not to decide guilt or liability. Grand jury proceedings, preliminary examinations in criminal cases, extradition hearings, sentencing, bail hearings, and warrant applications all run outside the full evidence rules.1New Hampshire Judicial Branch. New Hampshire Rules of Evidence – Rule 1101 Applicability of Rules One important carve-out cuts the other way: privilege rules apply at every stage, even in otherwise exempt proceedings. A witness can refuse to answer a privileged question in front of a grand jury just as they could at trial.
Relevance and the Rule 403 Balancing Test
Every exhibit and every question has to clear relevance first. Under Rule 401, evidence is relevant if it makes any fact of consequence to the case more or less likely than it would be without that evidence.2New Hampshire Judicial Branch. Rule 401 – Test for Relevant Evidence The bar is low. The evidence doesn’t have to prove anything on its own; it just has to move the needle.
Rule 402 then makes relevant evidence generally admissible unless something specific blocks it, and it makes irrelevant evidence inadmissible, period.3New Hampshire Judicial Branch. Rule 402 General Admissibility of Relevant Evidence
Passing relevance does not guarantee admission. Rule 403 lets a judge exclude relevant evidence when its value is substantially outweighed by the danger of unfair prejudice, confusion of the issues, misleading the jury, undue delay, or piling on cumulative evidence.4New Hampshire Judicial Branch. New Hampshire Rules of Evidence – Rule 403 Excluding Relevant Evidence for Prejudice, Confusion, Waste of Time, or Other Reasons The operative word is “substantially.” Evidence is not excluded merely because it hurts the other side. Trial judges are given wide latitude on these calls, and appellate courts rarely disturb them.
Evidence Excluded for Policy Reasons
Some categories of relevant evidence are excluded not because they are unreliable but because letting them in would discourage useful conduct. Rule 407 blocks evidence of subsequent remedial measures when offered to prove negligence or fault, though it can still come in for other purposes such as proving ownership, control, or the feasibility of a precaution. Similar policy exclusions apply to settlement negotiations (Rule 408), offers to pay medical expenses (Rule 409), withdrawn guilty pleas and plea discussions (Rule 410), and liability insurance (Rule 411). Each of these can still be admitted for a purpose other than proving fault.
Character, Prior Bad Acts, and Habit
The general rule under Rule 404 is that you cannot use evidence of a person’s character to argue they acted in line with that character on a particular occasion.5New Hampshire Judicial Branch. Rule 404 Character Evidence Not Admissible To Prove Conduct In civil cases, character evidence is never admissible for that purpose. In criminal cases, a defendant may open the door by offering evidence of their own good character, and the prosecution can then respond.
Rule 404(b) covers other crimes, wrongs, or acts. Those cannot be used to show a general propensity toward bad behavior, but they can come in for specific purposes: motive, opportunity, intent, preparation, plan, knowledge, identity, or absence of mistake. In a criminal case, the prosecution must give reasonable pretrial notice of intent to use such evidence, and the court still applies the Rule 403 balancing test before admitting it.5New Hampshire Judicial Branch. Rule 404 Character Evidence Not Admissible To Prove Conduct When this evidence is admitted, the court usually instructs the jury to consider it only for the permitted purpose.
Habit is different from character and gets different treatment. Under Rule 406, evidence of a person’s habit or an organization’s routine practice is admissible to show the person or organization acted consistently with that habit on a particular occasion. A habit is a specific, repeated response to a particular situation. Character is a general trait. Locking a specific door on the way out of the building every night is a habit. Being “generally careful” is a character trait, and it does not come in.
Hearsay and Its Exceptions
Hearsay is the single most litigated area of evidence in New Hampshire courtrooms. Under Rule 801, hearsay is a statement made outside the current trial or hearing that a party offers to prove the truth of what the statement asserts. Rule 802 excludes hearsay as a general matter because the person who made the original statement is not on the stand where their credibility can be tested through cross-examination.6New Hampshire Judicial Branch. New Hampshire Rules of Evidence – Rule 802 The Rule Against Hearsay
Statements Defined as Not Hearsay
Rule 801(d) carves out two categories that look like hearsay but are not. Certain prior statements by a witness who is now testifying and subject to cross-examination qualify as non-hearsay, including prior inconsistent statements given under oath and statements identifying a person the witness previously perceived. And statements by an opposing party are not hearsay when offered against that party, including statements the party made personally, adopted, or that were made by their agents or employees on matters within the scope of the relationship.
Exceptions Regardless of Availability
Rule 803 sets out exceptions that apply whether or not the person who made the statement is available to testify.7New Hampshire Judicial Branch. Rule 803 Exceptions to the Rule Against Hearsay – Regardless of Whether the Declarant Is Available as a Witness The ones you see most often:
- Present sense impression: a statement describing an event made while, or immediately after, the person perceived it.
- Excited utterance: a statement made under the stress of a startling event, before the person had time to reflect.
- Business records: records kept in the regular course of a business, made at or near the time of the event by someone with knowledge, where the record-keeping is a routine practice.
- Public records: records of a public office setting out its activities, matters observed under a legal duty to report, or factual findings from an authorized investigation.
- Statements for medical diagnosis or treatment: statements describing symptoms, medical history, or the cause of a condition.
Exceptions When the Declarant Is Unavailable
Rule 804 adds exceptions that apply only when the person who made the statement is unavailable as a witness because they are dead, ill, beyond the court’s subpoena power, claiming a privilege, or refusing to testify despite a court order.8New Hampshire Judicial Branch. Rule 804 Exceptions to the Rule Against Hearsay – When the Declarant Is Unavailable as a Witness These include former testimony given under oath at a prior proceeding, statements made under the belief of imminent death, and statements against the declarant’s own interest.
The Residual Exception
Rule 807 is the catch-all. A hearsay statement that fits no specific exception may still come in if it carries sufficient guarantees of trustworthiness and is more probative on its point than any other evidence the proponent can reasonably obtain. The party offering the statement must give the opposing side reasonable written notice before trial, including the substance of the statement and the name of the person who made it, so the opponent has a fair chance to challenge it.9Legal Information Institute. Rule 807 Residual Exception Courts look at the totality of the circumstances, including any corroborating evidence, when deciding whether trustworthiness is adequate.
Who Can Testify and About What
The rules split witnesses into two categories with different limits.
Lay Witnesses
Under Rule 602, a witness can testify only about things they personally observed or experienced.10New Hampshire Judicial Branch. Rule 602 Need for Personal Knowledge Rule 701 limits lay opinions to those rationally based on the witness’s own perception and helpful to understanding their testimony or resolving a factual issue. A lay witness can estimate the speed of a car they saw. They cannot offer an opinion that depends on technical or scientific expertise.
Expert Witnesses and Daubert
Rule 702 allows a witness qualified by knowledge, skill, experience, training, or education to give an expert opinion if their specialized knowledge will help the jury understand the evidence or decide a factual issue. The testimony must be based on sufficient facts or data and produced through reliable principles and methods.11New Hampshire Judicial Branch. Rule 702 Testimony by Expert Witnesses
New Hampshire follows the Daubert standard, which makes the trial judge a gatekeeper on reliability before an expert reaches the jury.12New Hampshire Judicial Branch. New Hampshire Supreme Court – Daubert Standard Applied to Rule 702 Judges assessing an expert’s methods generally consider whether the theory or technique can be tested, whether it has been subjected to peer review and publication, the known or potential error rate, whether standards exist controlling its application, and whether it has gained general acceptance in the relevant field. An expert whose methodology fails that scrutiny will have their testimony excluded, which can be fatal to a case built on technical proof.
Impeaching a Witness
The rules give both sides tools to challenge a witness’s credibility.
Prior Criminal Convictions
Under Rule 609, a prior criminal conviction can be used to attack a witness’s character for truthfulness. If the crime involved dishonesty or a false statement, the conviction is generally admissible regardless of severity.13New Hampshire Judicial Branch. Rule 609 Impeachment by Evidence of A Criminal Conviction For other crimes, the court weighs probative value against the risk of unfair prejudice. A ten-year time limit applies: if more than ten years have passed since the conviction or release from confinement (whichever is later), the evidence comes in only if its probative value substantially outweighs the prejudicial effect and the proponent gives reasonable advance notice. Pardoned or annulled convictions are generally not admissible.
Prior Inconsistent Statements
Rule 613 allows a party to confront a witness with a prior statement that contradicts their current testimony. Extrinsic evidence of the inconsistency, such as a document or another witness, is admissible only if the witness is given a chance to explain or deny making the statement.14New Hampshire Judicial Branch. Rule 613 Witness’s Prior Statements This is where a deposition earns its keep. A witness who changes their story between deposition and trial can be confronted with the transcript. Used this way, the prior statement is admitted to undermine credibility, not to prove the truth of what the earlier statement said, unless it separately fits a hearsay exception.
Authenticating Exhibits
Before any physical item, document, or electronic record is admitted, the party offering it must show it is what they claim it to be. Under Rule 901, the proponent must produce enough evidence to support a finding of authenticity. This is a low bar. The judge does not decide whether the item is genuinely what it purports to be; the judge decides whether a reasonable jury could find it authentic, and the jury makes the ultimate call.
Common methods include testimony from a witness with personal knowledge, distinctive characteristics of the item itself, and expert comparison. Phone calls can be authenticated through the circumstances, such as dialing a number assigned to a person and recognizing their voice.
Self-Authenticating Categories
Rule 902 lists items considered trustworthy enough on their face that no outside proof of authenticity is required:15New Hampshire Judicial Branch. New Hampshire Supreme Court Order Adopting Amendment to Evidence Rule 902
- Sealed and signed public documents.
- Certified copies of public records.
- Official publications issued by a public authority.
- Printed material that appears to be a newspaper or periodical.
- Trade inscriptions such as labels, signs, and tags affixed in the course of business.
- Acknowledged documents accompanied by a certificate of acknowledgment from an authorized official.
Electronic Records
Rule 902 was amended to address electronic evidence. Certified data copied from an electronic device, storage medium, or file can be self-authenticating if the copying process is verified through digital identification and accompanied by a certification from a qualified person.15New Hampshire Judicial Branch. New Hampshire Supreme Court Order Adopting Amendment to Evidence Rule 902 The proponent must give the opposing party reasonable written notice and an opportunity to inspect the record and certification before trial. Social media posts, text messages, and similar digital material that does not come with a certification are usually authenticated with circumstantial evidence: the content of the messages, the account owner’s identity, and metadata.
Privileged Communications
New Hampshire recognizes several privileges that protect confidential communications from disclosure. Rule 502 establishes the attorney-client privilege, which allows a client to prevent disclosure of confidential communications made for the purpose of obtaining legal advice.16New Hampshire Judicial Branch. Rule 502 Lawyer-Client Privilege The privilege belongs to the client, not the attorney, so only the client can waive it. It does not cover communications made to further a crime or fraud, and it can be waived inadvertently if reasonable steps are not taken to maintain confidentiality.
Other recognized privileges include spousal, physician-patient, and psychotherapist-patient. Because privilege rules apply at every stage under Rule 1101, a witness can invoke a privilege even in proceedings where the other evidence rules are relaxed.
Preserving an Evidence Issue for Appeal
A bad evidence ruling at trial helps you on appeal only if the issue was properly preserved. Under Rule 103, a party claiming error in an evidentiary ruling must show that a substantial right was affected and that the nature of the error was brought to the trial court’s attention. If evidence was wrongly admitted, you preserve the issue by making a timely objection and stating the specific ground. If evidence was wrongly excluded, you preserve it through an offer of proof that tells the court what the evidence would have shown.
Timing matters. An objection made after a witness has answered is often too late, unless the objectionable nature of the answer was not foreseeable. The objection also has to be specific enough that the trial judge understands the legal basis. A vague “objection” without a stated ground usually preserves nothing. Failing to preserve an evidentiary error generally waives it, although appellate courts retain the ability to notice plain errors that affect substantial rights.
Perjury
Testimony in New Hampshire is given under oath, and lying under oath carries serious consequences. Under RSA 641:1, a person who makes a false material statement under oath in an official proceeding, knowing it to be untrue, is guilty of perjury.17New Hampshire General Court. New Hampshire Code 641-1 – Perjury Perjury is a Class B felony, which carries a maximum sentence of up to seven years in state prison.18New Hampshire General Court. New Hampshire Code 651-2 – Sentences and Limitations A witness caught in a material lie can also expect the rest of their testimony to be discredited, often taking the case that depended on it down with them.
