- Medida provisória 2.200-2 (Portuguese) - Brazilian law states that any digital document is valid for the law if it is certified by ICP-Brasil (the official Brazilian PKI) or if it is certified by other PKI and the concerned parties agree as to the validity of the document.
- PIPEDA - Canadian law distinguishes between the generic "electronic signature" and the "secure electronic signature". Federal secure electronic signature regulations make it clear that a secure electronic signature is a digital signature created and verified in a specific manner. Canada's Evidence Act contains evidentiary presumptions about both the integrity and validity of electronic documents with attached secure electronic signatures, and of the authenticity of the secure electronic signatures themselves.
- Electronic Signature Law of the People's Republic of China (Chinese/English) - The stated purposes include standardizing the conduct of electronic signatures, confirming the legal validity of electronic signatures and safeguarding the legal interests of parties involved in such matters.

Court decisions discussing the effect and validity of digital signatures or digital signature-related legislation:
- In re Piranha, Inc., 2003 WL 21468504 (N.D. Tex) (UETA does not preclude a person from contesting that he executed, adopted, or authorized an electronic signature that is purportedly his).
- Cloud Corp. v. Hasbro, 314 F.3d 289 (7th Cir., 2002) EMLF.org (E-SIGN does not apply retroactively to contracts formed before it took effect in 2000. Nevertheless, the statute of frauds was satisfied by the text of E-mail plus an (apparently) written notation.)
- Sea-Land Service, Inc. v. Lozen International, 285 F.3d 808 (9th Cir., 2002) Admiraltylawguide.com (Internal corporate E-mail with signature block, forwarded to a third party by another employee, was admissible over hearsay objection as a party-admission, where the statement was apparently within the scope of the author's and forwarder's employment.)
