How to start signing with ZealiD?

Here's a short intro how global signature signing works:

  • Citizens of Lithuania and Estonia can log in with Mobile-ID, Smart-ID, ZealiD;
  • Latvian – Smart-ID and ZealiD;
  • Citizen of another country - ZealiD.



  1. 2. Upload the document, invite members and sign.
  • If you are a citizen of the Baltic States, you can sign documents with your M. signature or Smart-ID app.
  • NB: If you want to pay for another person's signature by yourself, check the box Deduct the signature from my account.
  • If the other signatory is a foreign citizen, he will be able to connect to app.marksign.lt and sign documents using the ZealiD application.
