Legal Definitions - legal signature

A legal signature is a person's name or mark written by that person or at their direction. It is used to authenticate a document and can be any name, mark, or writing used with the intention of doing so.

For example, when signing a contract, a person's signature at the end of the document is their legal signature. This signature shows that they agree to the terms of the contract and that they are the person who signed it.

Another example is a digital signature, which is a secure, digital code attached to an electronically transmitted message that uniquely identifies and authenticates the sender. This type of signature is important for electronic commerce and is a key component of many electronic message-authentication schemes.

Overall, a legal signature is a way to verify the authenticity of a document and ensure that the person who signed it is the one who intended to do so.
