Regulations in the United States

There are two laws that regulate electronic signatures in the United States: the E-Sign Act at federal level, and the UETA Act. They do not distinguish between types of electronic signatures, unlike European legislation, which establishes three types of signatures: simple, advanced and qualified. But both U.S. laws do require an accredited record of the operation, and the applicant and signer must each receive a copy of the signed document at the end of each transaction, as well as access to said document in a printable PDF format.
Requirements established by European legislation are more demanding than those required by American regulations for electronic signatures, and it establishes three types of signatures according to the level of security: simple, advanced and qualified. Therefore, it can be assumed that electronic signatures that comply with European regulations would also comply with U.S. regulations, provided that a federal law does not impose specific technical characteristics..
