Email and cloud-based file sharing services such as Gmail, One Drive, and Dropbox are generally considered safe for sharing non-sensitive information, but they may not be suitable for sharing confidential or sensitive information. The primary concern with using these services for confidential information is that they are not always secure and may be vulnerable to hacking or data breaches. Additionally, these services are not typically designed for the specific purpose of sharing legal documents, and may not have the same level of security as specialized legal document sharing platforms.
It is common for clients to share evidence with their lawyers via email or file sharing services, but it is important to be aware of the potential risks and to take steps to protect confidential information.
It is always a good idea to verify with your lawyer the best way to share evidence and to ensure that your evidence is protected and secure. Your lawyer may also have a preferred method for receiving evidence and it is important to discuss with them what is the best way to share your evidence.
