Is digital signing legally valid?

Yes. Electronic signatures are legally valid under the European eIDAS regulation. BuiltSign also records a full audit trail with timestamp, IP address and email verification, so you can prove who signed and when.

What is the difference between digital and electronic signing?

In practice both terms are used for the same thing: signing a document online without pen and paper. Legally, the eIDAS regulation defines electronic signatures at three levels: standard (SES), advanced (AES) and qualified (QES).

How do I place a digital signature on a document?

Upload the document to BuiltSign, place a signature field and sign with your mouse, finger or a typed signature. If someone else needs to sign, send them a signing link.

Does the recipient need to install anything or create an account?

No. The recipient opens the link and signs directly in the browser, on phone or computer. No registration or app required.

Audit trail and certificate

Every signature is recorded with timestamp, IP address and email verification. The certificate is your legal proof.

Works on any device
