Yes, an electronically signed document cannot be denied in court solely due to the fact that it is signed electronically.
In addition, both parties not only receive the signed document, but also a signing log with added value, such as: time stamps, email addresses, all changes made to the document and ip-addresses.
Also, you will receive the hash codes of the documents. A hash code is a code that can be generated from a document. The code is unique for the document. This means that any changes made to the document after the signing process is closed can be detected by comparing the hash codes. A document cannot be changed without you knowing it's changed.
So, in short, your signed document will have more information and security than with the process of printing, signing and scanning or posting. For more detailed information about international laws regulating electronic signatures have a look here.
