Signing with a code sent by email is a simple electronic signature, as provided for by the European eIDAS Regulation (Regulation (EU) No 910/2014, Article 25).

What this means

  • A court can't reject it just because it's electronic.
  • It counts as evidence. How much weight it carries is up to the judge, case by case, looking at the other evidence too.
  • The certificate helps: it states who signed, when, with what verification, and it seals the content.

What it's good for

Accepting quotes, proposals, orders, engagements and everyday business agreements, where you need a written, traceable confirmation.

When you need something else

By law, some deeds require an advanced or qualified signature, for example the sale of a property. In these cases you need a qualified signature tool. If you're unsure about a specific case, ask your accountant or a lawyer.
