合同签署中电子签名的法律依据

合同签署中电子签名的法律依据英文回答：
U.S. Laws Regarding Electronic Signatures.
The Electronic Signatures in Global and National Commerce Act (ESIGN) established the legal framework for electronic signatures in the United States. ESIGN defines an electronic signature as "an electronic sound, symbol, or process, attached to or logically associated with a contract or other record and executed or adopted by a person with the intent to sign the record."
ESIGN establishes that electronic signatures are
legally binding and enforceable in the same manner as traditional handwritten signatures. However, ESIGN does not mandate the use of electronic signatures and allows for the use of traditional handwritten signatures if preferred.
Additional State Laws.
In addition to ESIGN, many states have enacted their own electronic signature laws. These laws generally mirror the requirements of ESIGN, but some states may have additional requirements or provisions. For example, some states require that electronic signatures be accompanied by a digital certificate or other form of authentication.
It is important to check the specific electronic signature laws of the state(s) where the contract will be signed and enforced to ensure compliance.
International Laws Regarding Electronic Signatures.
The United Nations Convention on the Use of Electronic Communications in International Contracts (UNCITRAL Model Law) provides a framework for the international recognition of electronic signatures. The Model Law has been adopted by many countries around the world, including the European Union.
The Model Law recognizes the validity of electronic
signatures, provided that certain requirements are met. These requirements include:
The electronic signature must be linked to the signatory in a manner that ensures its uniqueness.
The signatory must have consented to the use of the electronic signature.
The signatory must have intended to sign the document.

电子签名在合同签署中的法律依据。

在美国，《全球和国内商务电子签名法案》(ESIGN) 确立了电子签名的法律框架。

ESIGN 将电子签名定义为“附加或逻辑上关联到合同或其他记录，并由以签名记录为目的而执行或采用的个人所附加的电子声音、符号或流程”。

ESIGN 规定电子签名具有与传统手写签名相同的法律约束力和可执行性。

但是，ESIGN 并没有强制要求使用电子签名，而是在需
要时允许使用传统的手写签名。

其他州法律。

除了 ESIGN 外，许多州还颁布了自己的电子签名法律。

这些法
律通常反映了 ESIGN 的要求，但一些州可能具有其他要求或条款。

例如，一些州要求电子签名附有数字证书或其他形式的认证。

务必查看合同的签署和执行所在州(各州) 的具体电子签名法律，以确保合规性。

电子签名在国际上的法律。

联合国国际合同中使用电子通信公约 (UNCITRAL 示范法) 为国
际认可电子签名提供了框架。

该示范法已被世界许多国家采纳，包
括欧盟。

该示范法承认电子签名的有效性，但前提是满足某些要求。

这
些要求包括：
电子签名必须以确保其独特性性的方式链接到签署者。

签署者必须同意使用电子签名。

签署者必须有签署文件的主观意愿。
