Use Case — Estate Planning
Timestamp Digital Wills and Trust Documents
Prove when estate planning documents existed — complementing notarization with independent, tamper-proof date verification.
Why Proving Document Dates Matters in Estate Disputes
Estate disputes often hinge on timing. Which version of a will is the most recent? Was a trust amendment signed before or after a change in family circumstances? Did a power of attorney exist before the grantor lost capacity? The party that can prove when a document existed — and that it has not been altered since — holds the strongest position.
Traditional estate documents are dated by hand, witnessed, and sometimes notarized. But notarization only verifies the identity of the signer on the signature page — it does not verify the contents of every other page. A notarized date can be challenged if the document's interior pages lack independent verification.
Digital estate documents face an additional challenge: file metadata (creation dates, modification timestamps) can be altered by anyone with access to the file. Cloud storage timestamps depend on the provider. Email delivery dates can be disputed. None of these constitute independent proof.
What estate planners need is a way to independently prove that a specific version of a document existed at a specific point in time — and that no page has been altered since.
How Timestamping Complements Notarization
Notarization proves who signed. Timestamping proves what was signed and when. Together, they create the strongest possible record for estate documents.
When you timestamp a document with EverCert, its entire contents are hashed using SHA-256 — producing a unique cryptographic fingerprint that covers every page, every word, every pixel. This fingerprint is anchored to the Bitcoin blockchain via OpenTimestamps, creating a permanent public record.
If any page is altered after timestamping — a beneficiary name changed, a clause added, a page swapped — the hash is completely different and verification fails. This means every page is protected, not just the signature page.
The proof is independently verifiable by anyone — executors, beneficiaries, attorneys, or courts — using open-source tools. No reliance on EverCert or any third party. Your document never leaves your device; only the hash is transmitted.
