Certify digital evidence for divorce and family proceedings
Before your spouse deletes their messages or social posts, create certified proof that holds up under cross-examination. A signed, timestamped record of a WhatsApp conversation, email, or Facebook post is harder to dismiss in family court than a screenshot.

Why a screenshot is not enough.
In contested family proceedings, opposing counsel will routinely challenge the authenticity of self-captured screenshots. Four specific weaknesses come up again and again:
✗
WhatsApp screenshots can be fabricatedFree tools generate convincing fake chat images. Courts know this.
✗
Timestamps and phone numbers are editableThe date, sender name, and message body can all be altered in any photo editor.
✗
The other party may delete the originalOnce the source is gone, you have no way to corroborate the screenshot.
✗
No independent third-party proof of timeYour phone clock is not authoritative. A qualified timestamp authority is.
What a certified divorce-evidence package contains.
Every instantproof.legal certificate ships with the same evidence chain — readable as a PDF, verifiable as cryptographic files.
Browser session video
For WhatsApp Web, social media, or any logged-in content — a real-time recording of the conversation as it appeared.
Network log (HAR)
Every request the browser made during the session — proof of which platform served the content and when.
RFC 3161 timestamp
An independent third-party signature binding the evidence to a specific moment in time.
SHA-256 hashes
Cryptographic fingerprints of every file in the package — any later edit breaks the hash.
Metadata ZIP
Manifest, signature, public key, and timestamp request/response — everything needed to re-verify offline.
How to preserve divorce evidence in four steps.
Each capture takes a few minutes. Do not delay — once content is deleted by the other party, it cannot be recovered.

How to capture each evidence type.
Short guides for the three most common content types in divorce matters. Each links to a full how-to page.
WhatsApp conversations
Open WhatsApp Web inside a Browser Session, scroll through the chat, and finish — the recording is timestamped and signed.
Email and forwarded notices
Open the email in a browser session or upload a saved .eml/PDF as a File certificate.
Live browsing sessions
Record the full interaction — useful for hidden-asset reviews, dating profiles, or deleted posts captured via web.archive.
Divorce-evidence questions, answered directly.
Can WhatsApp screenshots be used in divorce court?
Screenshots can be submitted but are routinely challenged because they are easy to edit. A certified browser session recording of WhatsApp Web is far harder to dispute. It captures the conversation in real time with a qualified RFC 3161 timestamp.
How do I preserve social media posts before my spouse deletes them?
Open a website or browser session certificate at /certificates/new and enter the post URL. The platform captures the page, signs the content, and binds it to an independent timestamp before the post can be removed.
What digital evidence is admissible in family court?
Admissibility depends on jurisdiction, but evidence with a verifiable chain of custody, a qualified timestamp, and a cryptographic signature is consistently stronger than self-captured screenshots.
What about hidden assets — can browsing be certified?
Yes. A Browser Session records every page visited and every request made, alongside a signed video. Useful for showing a property listing, a dating profile, or an undisclosed account exists at a specific point in time.
Is this legal advice?
No. This service creates technical evidence artifacts. Legal admissibility depends on jurisdiction and circumstances. Consult qualified legal counsel for advice specific to your situation.
