Are text messages admissible in courtOften yes, if they are relevant and can be shown to be genuine

TimeBinder adds a layer of protection against AI and human fraud and disputes.

The file stays on your device. Your browser makes a digital fingerprint of the file. TimeBinder records the fingerprint and the time, not the file.

Short answer

Often yes. Text messages are commonly accepted as evidence if they are relevant and can be shown to be genuine, for example by the sender, the recipient, the phone or the carrier records. Screenshots alone are easier to challenge. Admissibility rules differ by country, court and state, so ask a lawyer about your case.

What courts look for

In US federal courts, an item must be authenticated: the proponent needs evidence that it is what they say it is (Federal Rule of Evidence 901). Examples listed in the rule include testimony of a witness with knowledge and the item’s appearance, contents and other distinctive characteristics taken together with all the circumstances. Rule 902(14) also allows data copied from an electronic device to be authenticated by a qualified person’s certification of a process of digital identification, such as a hash value.

Authentication is separate from other hurdles, such as whether a message is hearsay and whether it is relevant. Courts in other countries use different tests. A screenshot shows how a screen looked, and can be challenged; see are screenshots legal evidence and how to check if a text message is genuine.

Preserving texts before a dispute

Keep the phone and do not delete the thread. Export the conversation with dates, numbers and attachments using the phone’s or backup tool’s export, and keep the export file unchanged. A TimeBind records a SHA-256 fingerprint of the exact file and a time, anchored to Bitcoin. The fingerprint is made in your browser and the file is not uploaded.

Later, you can show the exported file is unchanged since that time. A TimeBind shows a file existed by a recorded time and has not changed since. It does not register copyright, is not legal advice and does not by itself prove who made the file. It does not show who sent a message. Ask a lawyer how to present messages in your court.

Frequently asked questions

Are text messages admissible in family court?

They can be, if relevant and shown to be genuine. Rules and practice vary by court and country, so check with a family lawyer.

Is a screenshot of a text message enough?

It can be used, but it is easier to challenge. Keeping the original messages on the device and an export is stronger.

Can deleted texts be used as evidence?

Sometimes they can be recovered from the device, a backup or carrier records, but that depends on the case and the law.

Does a timestamp prove who sent a text?

No. It only shows the exported file existed by a recorded time and has not changed since.

Your file’s fingerprint, anchored to a global network secured by real electricity and cryptography.

Editing a file—including with AI—changes its fingerprint, not its existing network record.

How this works

Your file’s SHA-256 fingerprint, a short code worked out from its exact contents, is made in your browser, and the file itself stays on your device. A cryptographic commitment to that fingerprint, which may be combined with others, is then anchored in a block on the Bitcoin blockchain. Bitcoin is secured by proof of work: computers around the world spend real electricity to add each block, and changing an earlier block would mean redoing that work faster than the rest of the network. Until that block is confirmed, your proof is pending. Once the Bitcoin anchoring is confirmed, you can verify the proof against that recorded commitment. The confirmed record can then be checked; Pooled TimeBinds are checked through TimeBinder, while ASAP TimeBinds can also be checked independently. If you check the file later and its fingerprint still matches, that shows the file existed no later than the recorded time. The record doesn’t show who made the file, whether AI was used, or that its contents are true.
