Are Text Messages Admissible in Court?

Yes. Text messages are admissible in every U.S. court, state and federal, when the party offering them shows three things: the messages are relevant, they are authentic (sent by the person claimed, and shown in a complete and unaltered form), and they are either not hearsay or fall within a hearsay exception. Most disputes over text-message evidence are about the second requirement, authentication, and most authentication problems trace back to how the messages were collected.

This page explains the three requirements, what each of the major jurisdictions requires, and how to collect texts so they hold up. It links to detailed guides for each topic.

The three requirements

1. Relevance

The message must make a fact that matters to the case more or less likely. This is a low bar and rarely the problem, though a court can still exclude a relevant text if its unfair prejudice substantially outweighs its value.

2. Authentication

The proponent must produce enough evidence for the factfinder to conclude the message is what it is claimed to be. The federal rule, FRE 901(a), reads:

"To satisfy the requirement of authenticating or identifying an item of evidence, the proponent must produce evidence sufficient to support a finding that the item is what the proponent claims it is."

State rules are worded almost identically. For a text message, authentication has two layers: authorship (who sent it) and integrity (is this exhibit a complete, unaltered copy of the conversation).

Authorship is usually shown circumstantially. FRE 901(b)(4) allows authentication by "the appearance, contents, substance, internal patterns, or other distinctive characteristics of the item, taken together with all the circumstances." A phone number alone is a weak start; content that only the sender would know, replies to calls placed during the exchange, the sender's profile, and matching copies on the other party's phone are what courts look for.

Integrity is where the collection method matters. A screenshot proves only that a screen looked a certain way at some moment. A device extraction with recorded hashes, timestamps and an audit log lets a witness or a certification establish that the exhibit matches what was on the phone.

3. Hearsay

A text is hearsay only if it is offered to prove the truth of what it says (FRE 801(c)). Texts offered to show that a statement was made, that someone had notice, or as a verbal act are not hearsay. Texts written by the opposing party and offered against them are admissible as an opposing party's statement (FRE 801(d)(2)). Full treatment: Are text messages hearsay?

Federal court

Federal courts apply the Federal Rules of Evidence. Beyond 901(b)(4), two rules added in 2017 are specifically useful for phone extractions. FRE 902(13) makes self-authenticating "a record generated by an electronic process or system that produces an accurate result, as shown by a certification of a qualified person," and FRE 902(14) does the same for "data copied from an electronic device, storage medium, or file, if authenticated by a process of digital identification, as shown by a certification of a qualified person." In practice, that means a hash-verified extraction with a proper certification and advance notice can be admitted without live foundation testimony.

Two cautionary federal cases: in United States v. Vayner, 769 F.3d 125 (2d Cir. 2014), the Second Circuit vacated a conviction because a social-media profile printout was admitted with no evidence that the defendant created or controlled the page; his name and photo on it were not enough. In United States v. Safavian, 435 F. Supp. 2d 36 (D.D.C. 2006), emails were authenticated under 901(b)(4) by their addresses, signature blocks and content. More: Texts and WhatsApp in federal court.

California

California requires authentication under Evidence Code §§ 1400–1401 before a writing "may be received in evidence," and treats every electronic message as a writing. Authentication can be by a witness who saw the message made (§ 1413) or by content "unlikely to be known to anyone other than" the claimed author (§ 1421), and the courts have held that the author's testimony is not required. Printouts of computer data and digital images carry a rebuttable presumption of accuracy (§§ 1552–1553). In Adoption of X.D. (Cal. Ct. App. Sept. 29, 2025, No. B343632), the Court of Appeal held that screenshots of text messages were authenticated even though the sender denied writing them and the recipient did not testify: the sender's admissions that the phone number and nickname were his, a third party's testimony about receiving the screenshots, and corroborating evidence were enough, and the trial court erred in insisting on the recipient's testimony. The hearsay rule is Evidence Code § 1200; the opposing-party exception is § 1220.

Texas

Texas Rule of Evidence 901(a) mirrors the federal rule: the proponent "must produce evidence sufficient to support a finding that the item is what the proponent claims it is." The Court of Criminal Appeals has addressed electronic messages directly. In Tienda v. State, 358 S.W.3d 633 (Tex. Crim. App. 2012), social-media pages were authenticated by their internal content: photos, nicknames, tattoos and references to the events at issue. In Butler v. State, 459 S.W.3d 595 (Tex. Crim. App. 2015), the court held that evidence "that merely shows the association of a phone number with a purported sender—alone—might be too tenuous," but that the content and context of the texts, including the defendant calling the recipient in the middle of the exchange, was enough for the jury to find he wrote them.

Florida

Florida Statute § 90.901 provides: "Authentication or identification of evidence is required as a condition precedent to its admissibility. The requirements of this section are satisfied by evidence sufficient to support a finding that the matter in question is what its proponent claims." In Symonette v. State, 100 So. 3d 180 (Fla. 4th DCA 2012), photographs of text messages on a phone seized from the defendant were authenticated by the circumstances of the seizure and a co-participant's testimony, and admitted as party admissions. The Fourth District went the other way in Walker v. Harley-Anderson (Fla. 4th DCA Sept. 9, 2020, No. 4D19-2216), reversing an injunction because nothing beyond the recipient's word tied the texts to the sender: "Testimony that a person received a text or email from another is not sufficient, by itself, to authenticate the identity of the sender."

New York

New York has no single codified evidence code; authentication follows common-law principles, and CPLR 4518(a) governs business records, including electronic records offered "in a tangible exhibit that is a true and accurate representation of such electronic record." The Court of Appeals settled the text-message question in People v. Rodriguez, 38 N.Y.3d 151 (2022): screenshots of text messages were properly authenticated by the victim, "a participant in and witness to the conversations with defendant," and the testimony of the person who took the screenshots was not required. Earlier, in People v. Green, 107 A.D.3d 915 (2d Dept. 2013), texts were authenticated by their content and the complainant's testimony that the photographs accurately showed her phone.

Other states

Every state has an authentication rule modeled on FRE 901 or a common-law equivalent, and the analysis above transfers. One widely cited outlier worth knowing: in Commonwealth v. Koch, 39 A.3d 996 (Pa. Super. 2011), the Superior Court held that texts found on a phone the defendant possessed should not have been admitted, because nothing showed she wrote them; authentication of electronic communications "requires more than mere confirmation that the number or address belonged to a particular person." An evenly divided Pennsylvania Supreme Court affirmed in 2014, so the Superior Court's rule remains the law in Pennsylvania.

What kind of text-message evidence holds up

The pattern across all of these cases is consistent. Courts admit texts when the proponent can show authorship through content and circumstances, and can show that the exhibit is a complete and faithful copy. They exclude texts when the only link is a phone number, or when the exhibit is an unexplained image.

Hearsay's Text Message Collector produces the third kind: SMS, MMS, RCS, iMessage and WhatsApp collected from iPhone and Android on the client's own computer, with encryption hashes, audit logs and chain-of-custody documentation, exported to PDF, Excel, RSMF and other formats. Signed affidavits and expert testimony are available when a matter needs them: Expert witness and affidavits.

Frequently asked questions

Are screenshots of text messages admissible in court?

They can be, if authenticated and not barred by the hearsay rule, and courts have admitted them (for example People v. Rodriguez in New York and Adoption of X.D. in California). They are also the easiest form to challenge, because they show only part of a conversation and carry no integrity check.

Do I need the sender to testify to authenticate a text?

No. Courts in New York, Texas and Florida have admitted texts on the recipient's testimony combined with circumstantial evidence of authorship, and California's Court of Appeal has admitted screenshots where the sender denied authorship and the recipient did not testify at all. The sender's testimony helps but is not required.

Can I use text messages in family court?

Yes. The same three requirements apply in custody, divorce and domestic-violence matters, and texts are among the most common exhibits in those cases. Because the parties usually know each other well, authorship is often easy to show through content.

Are deleted text messages admissible?

If they can be recovered (from the other party's device, a backup, or the device itself) they are analyzed like any other text. See Navigating the challenges of deleted messages.

Are text messages hearsay?

Only when offered to prove the truth of what they say. Messages from the opposing party, offered against them, are admissible under the opposing-party rule. See Are text messages hearsay?
