Is an electronic signature legally binding?

In most cases, yes. In the United States, the United Kingdom and Norway, a signature cannot be refused only because it is electronic. Some documents need more than that: a witness, a notary, or a check of who the person is. Ask a lawyer about yours.

What VamoSign records

• The signing link goes only to the signer's own e-mail inbox, or their phone.
• The signer reads what will be recorded and ticks a consent box before signing.
• The certificate page lists each name as typed, the e-mail address, the time of every step, the IP address, and the document's SHA-256 checksum.
• The sealed PDF carries VamoSign's digital signature and a timestamp from an independent time source, so a change to the file shows up in any PDF reader.
• Anyone can upload a sealed PDF and check it against VamoSign's record.

What VamoSign does not do

• It does not check who a person is beyond their e-mail inbox or phone.
• It does not tell you whether your document may be signed electronically, or needs a witness or a notary.

The laws

United States: the ESIGN Act and UETA. United Kingdom: the Electronic Communications Act 2000 and the eIDAS regulation as kept in UK law. Norway and the EU: the eIDAS regulation. A lawyer can tell you what they mean for your document.
