Legaltech: electronic signature mistakes that weaken evidentiary value

Published on 2026-04-164 min readFlorian

Evidentiary value doesn't hold by default

An electronic signature has legal value only if the integrity chain is clean. Many legaltech products settle for a "signed" PDF without the required rigor.

Weak angles

  • qualified timestamp missing or unverified;
  • signer identity validated only by SMS code;
  • signed file editable after signature without detection;
  • no audit trail available to the parties.
  • The simple test

    Can an opposing lawyer contest the signature with solid arguments? If yes, the product doesn't deliver its promise, even if the UI works fine.
