Legally binding eSignatures

Documents and agreements eSigned with QuickSigner are legally recognized in the USA, UK and all EU member states.

In the USA, as per the ESIGN Act, electronic signatures are legal in every state and U.S. territory where federal law applies. Where federal law does not apply, 49 U.S. states have adopted the Uniform Electronic Transactions Act (UETA), which was published by the Uniform Law Commission (then the National Conference of Commissioners on Uniform State Laws) in 1999.

In the UK, online and electronic signatures carry legal recognition and are governed by several legislative instruments. These include the Electronic Identification and Trust Services for Electronic Transactions Regulations (2016), the Electronic Communications Act of 2000 (ECA), and the UK’s adapted version of Regulation (EU) No 910/2014 of the European Parliament and of the Council of 23 July 2014 on electronic identification and trust services for electronic transactions (eIDAS).

In the EU, since July 1, 2016, all the member states have adopted the eIDAS regulation, a regulation on the legal effect of electronic signatures.

QuickSigner uses the PAdES standard for Advanced Electronic Signatures and is backed by the Adobe Approved Trust List (AATL).
