The problem
Legal PDFs often move through email threads, data rooms and external stakeholders. A recipient may need to know whether the received file is exactly the document issued by the firm.
Law firms
Client letters, transaction documents, exhibits and sensitive legal PDFs
Give sensitive legal PDFs a verifiable authenticity layer.
DocSeal helps law firms make selected PDFs verifiable by clients, counterparties, lenders and external advisors after the files leave the firm.
The DocSeal answer
DocSeal records a cryptographic fingerprint of the issued PDF and provides a verification link. The recipient checks file integrity without access to internal matter systems.
Priority use cases
Start with documents that leave your secure environment and may later be forwarded, reused or challenged.
Client letters and confirmations
Transaction documents
Sensitive attachments and exhibits
Documents exposed to forwarding or modification risk
Positioning: a narrow authenticity layer, not another legal practice platform.
