Texas Rules of Evidence: Hearsay, Privileges, and Authentication

The Texas Rules of Evidence are the body of rules, adopted by the Texas Supreme Court and the Court of Criminal Appeals, that decide what information a judge or jury is allowed to consider in a Texas civil or criminal case. They apply across the state’s court system, from justice-of-the-peace hearings up through district court trials, and they govern everything from whether a photograph can be shown to the jury to whether a witness can repeat what someone else said. The rules exist to keep unreliable and unfairly prejudicial material out of the record while letting useful information in.¹

If you are involved in a Texas case as a party, a witness, or someone trying to understand what will actually be presented in court, the rules below are the ones that matter most.

Relevance Is the First Gate

Every item offered in a Texas courtroom has to clear relevance before anything else matters. Rule 401 defines evidence as relevant if it makes any fact of consequence to the case even slightly more or less probable. That is a deliberately low bar. Rule 402 then sets the default: relevant evidence comes in unless the U.S. or Texas Constitution, a statute, or another rule keeps it out.¹

The real fight tends to happen under Rule 403. A judge can exclude relevant evidence when its probative value is substantially outweighed by the danger of unfair prejudice, confusion, or misleading the jury. The word “substantially” matters. The scale tilts toward admission, and the party trying to keep the evidence out carries the heavier burden. A gruesome crime-scene photo may be relevant to show the manner of death, but if the same point can be made with less inflammatory evidence, a judge has discretion to exclude it. Rule 403 rulings are among the most frequently litigated calls in Texas trial courts because so much turns on the judge’s judgment.

Character Evidence and Prior Bad Acts

Rule 404 carries one of the most counterintuitive principles in evidence law: you generally cannot use someone’s character to prove they acted a certain way on a specific occasion. In a fraud case, the other side cannot bring witnesses just to say the defendant is “the kind of person who lies.” That propensity reasoning is exactly what Rule 404(a) blocks.¹

Texas carves out exceptions. In criminal cases, a defendant can introduce evidence of a relevant character trait, and once the defendant opens that door, the prosecution can respond. Texas also extends character evidence to civil cases in a way the federal rules do not: a party accused of conduct involving moral turpitude can offer evidence of a pertinent character trait. Victim character traits can come in under certain circumstances, particularly in self-defense cases.

Rule 404(b) handles evidence of other crimes, wrongs, or acts. It cannot be used to show propensity, but it can be admitted for other purposes, including motive, intent, plan, knowledge, identity, or absence of mistake. In criminal cases, the prosecution must give the defense reasonable pretrial notice if it plans to use this kind of evidence, because prior-act evidence is powerful with juries and defendants need time to respond.

Who Can Testify and What They Can Say

Texas starts from the presumption that every person is competent to testify. Rule 601 sets a floor rather than a ceiling. A witness can be disqualified only in narrow situations, such as when the person genuinely cannot understand the obligation to tell the truth. Outright disqualification is rare. Courts generally let the jury weigh credibility instead of barring the witness.¹

Rule 602 adds a separate requirement: personal knowledge. A witness can testify only about what they perceived through their own senses. A witness who says “my neighbor told me she saw the accident” is testifying about someone else’s perception, not their own, and that is where hearsay problems usually start.

Witnesses who lie under oath face real criminal exposure. Basic perjury under the Texas Penal Code is a Class A misdemeanor, with up to one year in county jail. When the false statement happens in an official proceeding and is material to the case, the charge becomes aggravated perjury, a third-degree felony punishable by two to ten years in prison.²

Lay Opinions

Rule 701 lets ordinary witnesses offer opinions within tight boundaries. The opinion must be based on what the witness actually perceived, and it must help the jury understand the testimony or resolve a factual dispute. A lay witness can say “the car looked like it was going about 50 miles per hour” because that opinion comes from observation. A lay witness cannot offer opinions that require scientific or technical expertise.¹

Experts and the Robinson Standard

Expert witnesses work under a different rule. Rule 702 allows someone with specialized knowledge, skill, training, or experience to offer opinions that go beyond ordinary observation, as long as the testimony helps the jury understand the evidence or decide a fact in issue.¹ The trial judge is the gatekeeper. In Texas, the reliability analysis follows the framework from the Texas Supreme Court’s decision in E.I. du Pont de Nemours v. Robinson rather than the federal Daubert standard alone.

The Robinson framework includes the four Daubert factors (whether the theory can be tested, whether it has been peer-reviewed, its error rate, and whether it is generally accepted in the relevant field) plus two Texas additions: the extent to which the technique depends on the expert’s subjective interpretation, and whether the theory or technique has non-judicial uses. Judges apply whichever factors help assess reliability rather than mechanically running through all of them. When the Robinson factors are a poor fit for a particular field, Texas courts use what is often called the “analytical gap” test, excluding testimony when the distance between the expert’s data and the expert’s conclusion is simply too wide.

Impeaching a Witness’s Credibility

Attacking credibility is one of the most powerful tools in trial practice. Under Rule 607, any party can attack the credibility of any witness, including its own. Rules 608 and 609 then set the boundaries for the two most common methods.

Rule 608 allows a witness’s character for truthfulness to be attacked through reputation or opinion testimony. Evidence of a truthful character is admissible only after the other side has already attacked the witness’s credibility. You cannot preemptively bolster your own witness. Rule 608(b) also imposes a sharp limit: a party generally cannot introduce extrinsic evidence (documents or other witnesses) to prove specific instances of conduct bearing on truthfulness. The main exception is a criminal conviction admitted under Rule 609.¹

Rule 609 governs impeachment by prior conviction, and Texas diverges significantly from the federal rules here. Texas allows impeachment with any felony conviction or any conviction involving moral turpitude, regardless of the punishment level, as long as the court finds the probative value outweighs the prejudicial effect. The federal rules use the narrower phrase “dishonest act or false statement,” which excludes many crimes Texas courts treat as crimes of moral turpitude.³

Convictions older than ten years, measured from the conviction or release from confinement (whichever is later), face a higher bar. A stale conviction comes in only if its probative value substantially outweighs its prejudicial effect and the proponent gives the other side reasonable written notice. Convictions pardoned based on rehabilitation are inadmissible if the person has not committed another qualifying offense since. Juvenile adjudications are admissible only in criminal cases, only against witnesses other than the defendant, and only when admission is necessary to a fair determination of guilt or innocence.

Keeping Witnesses Out of the Courtroom

Rule 615, which Texas trial lawyers call “The Rule,” requires the court to exclude witnesses from the courtroom so they cannot hear each other’s testimony. Either party can invoke it, and the court can impose it on its own. The purpose is straightforward: if one witness hears another, there is a risk of testimony being tailored to match or contradict what came before.¹

Four categories of people are exempt. A party who is a natural person cannot be excluded from their own trial. An entity like a corporation can designate one officer or employee to remain as its representative. Anyone whose presence a party shows to be essential to presenting its case can stay. And anyone authorized by statute to be present is exempt. Courts can also issue broader orders prohibiting parties from sharing trial testimony with excluded witnesses outside the courtroom.

Privileges That Keep Information Out

Texas recognizes a broader set of evidentiary privileges than many people expect. Rules 501 through 513 protect specific categories of communication from being forced into evidence, even when the information would be relevant and useful to one side.³ The reasoning is that certain relationships depend on confidentiality, and forcing disclosure would undermine the relationship itself.

The lawyer-client privilege under Rule 503 is the most commonly invoked. It protects confidential communications made to facilitate legal services, and it belongs to the client, not the attorney. A client can waive it; a lawyer cannot unilaterally disclose protected communications. Related is the work-product doctrine, which protects documents an attorney prepares in anticipation of litigation. Work-product protection can extend to materials prepared by people other than the attorney, as long as the materials were created to prepare for a legal proceeding.

Other privileges Texas recognizes include:

Spousal privilege (Rule 504): Confidential communications between spouses during their marriage are protected, and in criminal cases a spouse may also refuse to testify against the other spouse.³
Clergy privilege (Rule 505): Confidential communications made to a member of the clergy acting as a spiritual advisor are protected.
Physician-patient privilege (Rule 509): In civil cases, confidential communications between a patient and physician and records of diagnosis, evaluation, or treatment are protected.
Mental health information privilege (Rule 510): Similar protection applies to mental health professionals in civil cases.
Trade secrets privilege (Rule 507): The owner can refuse disclosure unless the court finds that nondisclosure would conceal fraud or cause injustice.
Informer’s identity privilege (Rule 508): The identity of people who have furnished information to law enforcement or legislative investigators is protected.

Every privilege can be waived. Under Rule 511, voluntarily disclosing privileged information to a third party who is not covered by the privilege generally destroys the protection. Under Rule 513, neither the judge nor opposing counsel may comment on or invite the jury to draw an inference from a party’s decision to invoke a privilege. The jury never hears that someone “refused to answer because they had something to hide.”

Facts the Court Can Accept Without Proof

Not every fact needs a witness and a document trail. Under Rule 201, a court can take judicial notice of a fact that is not subject to reasonable dispute, either because it is generally known within the court’s area or because it can be verified from sources whose accuracy is beyond question.³ Common examples include the day of the week a given date fell on, the distance between two cities, or the content of a published government regulation.

A court can take judicial notice on its own, but it must do so if a party requests it and provides the supporting information. The practical difference between civil and criminal cases matters here. In a civil case, the judge instructs the jury to accept the noticed fact as conclusive. In a criminal case, the instruction is softer: the jury may accept or reject the noticed fact. That distinction protects a defendant’s right to have the jury independently evaluate every element of the charge.

Hearsay

Hearsay is probably the most misunderstood area of evidence law. Rule 801 defines it as a statement made outside the current trial or hearing, offered to prove the truth of what it asserts.¹ The concern is reliability. The person who made the statement is not in court, not under oath, and not subject to cross-examination; the jury cannot evaluate their demeanor or test their memory. Rule 802 makes hearsay inadmissible as a general rule.

That is only half the story. The rules carve out an extensive set of exceptions, and experienced litigators spend as much time navigating the exceptions as they do spotting hearsay.

Statements That Are Not Hearsay

Rule 801 itself classifies several types of statements as not hearsay at all. A witness’s prior inconsistent statement given under oath at a proceeding falls outside the definition, as does an opposing party’s own admission. When your opponent’s own words are offered against them, there is no hearsay problem, because the party is present in court and can explain or deny the statement. This is how most party admissions in depositions, emails, or recorded conversations get through the door.

Exceptions That Apply Regardless of Availability

Rule 803 lists exceptions that apply whether or not the person who made the statement is available to testify. The most commonly used include:

Present sense impression (803(1)): A statement describing an event while it is happening or immediately afterward. The theory is that there is no time to fabricate.
Excited utterance (803(2)): A statement made while under the stress of a startling event. The emotional shock is treated as a guarantee of spontaneity.
Statements for medical diagnosis (803(4)): Statements made to a doctor describing symptoms, medical history, or the general cause of an injury, as long as they were reasonably pertinent to diagnosis or treatment.
Business records (803(6)): Records created at or near the time of an event, by someone with knowledge, kept in the regular course of business, where making the record was a routine practice. The foundation can be laid through the testimony of a records custodian or through an affidavit under Rule 902(10).
Public records (803(8)): Records from a government office documenting its activities, matters observed under a legal duty to report, or factual findings from a legally authorized investigation.

Business records and public records are the workhorses of civil litigation. Medical records, banking logs, police reports, and government inspection reports all come in through these exceptions when properly authenticated.

Exceptions That Require Unavailability

Rule 804 provides additional exceptions, but only when the person who made the statement is unavailable to testify. “Unavailable” does not just mean absent. It includes claiming a privilege, refusing to testify despite a court order, lack of memory, death or illness, or inability to be brought to court through reasonable efforts.¹

The most dramatic exception is the dying declaration: a statement made by someone who believed death was imminent, about the cause or circumstances of their impending death. In Texas, this exception applies in homicide prosecutions and civil cases. Former testimony from an earlier proceeding also falls under Rule 804, as long as the party against whom it is offered had an opportunity to cross-examine the witness during the earlier proceeding.

The Residual Exception

Rule 807 is the catch-all. When a hearsay statement does not fit neatly into any Rule 803 or 804 exception, it can still be admitted if it has equivalent guarantees of trustworthiness, is offered as evidence of a material fact, and is more probative than any other evidence the proponent can reasonably obtain. The proponent must give advance notice, including the substance of the statement and the name of the person who made it. Courts treat this exception cautiously.

The Confrontation Clause Limit in Criminal Cases

Even when a hearsay exception technically applies, criminal defendants have a constitutional backstop. The Sixth Amendment’s Confrontation Clause guarantees the right to be confronted with the witnesses against you. In Crawford v. Washington, the U.S. Supreme Court held that testimonial statements from a witness who does not appear at trial are inadmissible unless the witness is unavailable and the defendant had a prior opportunity to cross-examine.⁴

Texas courts apply the “primary purpose” test to decide whether a statement is testimonial. The question is whether the statement was taken to establish past events or criminal activity (testimonial) or to deal with an ongoing emergency (non-testimonial). As a practical matter, formal police interrogation statements are almost always testimonial. Statements made during 911 calls while an emergency is unfolding are generally non-testimonial. Forensic lab reports and some autopsy reports sit in a gray area that Texas courts evaluate case by case. When a Crawford objection is raised, the prosecution bears the burden of showing the statement is admissible.

The Confrontation Clause does not apply in civil cases. It is exclusively a criminal defendant’s right, which is why hearsay exceptions operate differently in the two contexts. A business record admitted under Rule 803(6) rarely raises Confrontation Clause concerns because it was not created to prosecute anyone, while a lab report prepared specifically for a criminal case often does.

Authenticating Evidence

Before a physical object or document can be admitted, the offering party must show it is what they claim it is. Rule 901 requires enough evidence to support a finding of authenticity, a relatively low threshold. For physical evidence, this usually means testimony from someone who can identify the item and confirm the chain of custody. For documents, a witness who recognizes a signature or handwriting may be enough.¹

Self-Authenticating Documents

Rule 902 creates a shortcut for categories of evidence that are inherently reliable enough to skip the authentication testimony. Certified copies of public records, official government publications, newspapers, and trade inscriptions can all be admitted without a sponsoring witness. Texas Rule 902(10) also allows business records to be self-authenticated through an affidavit from the records custodian, which eliminates the need to subpoena a custodian to testify live just to lay the foundation for routine records.

Digital and Social Media Evidence

Social media posts, text messages, and other digital evidence present a distinct authentication challenge, because accounts can be hacked, spoofed, or fabricated. The most widely used standard asks whether a reasonable juror could conclude the evidence is what it claims to be, based on circumstantial evidence like the account name matching the person, the profile picture, references to details only the alleged author would know, or a phone number linked to the account. Some jurisdictions set a higher bar, requiring evidence that affirmatively rules out the possibility that someone else created or controlled the account.

Social media records are generally not self-authenticating under Rule 902, because platforms do not verify the truth of what users post. The party offering social media evidence almost always needs some external foundation, whether through a witness who can identify the account or through metadata and technical evidence from the platform itself.

The Best Evidence Rule

Rule 1002 requires the original writing, recording, or photograph when the content of that item is what a party is trying to prove. This is sometimes called the Best Evidence Rule. To prove what a contract says, you need the contract itself, not someone’s memory of its terms. Duplicates are generally acceptable under Rule 1003 unless a genuine question is raised about the authenticity of the original or admitting a copy would be unfair. When the original has been lost, destroyed, or cannot be obtained through reasonable means, other evidence of its content becomes admissible under Rule 1004.¹
