In the legal field, communication often involves exchanging highly sensitive and confidential information. Whether it's contracts, evidence, or case files, these documents contain details that, if compromised, could lead to severe consequences, including legal liability, reputational damage, or financial loss.
Unfortunately, email—one of the most common forms of communication—comes with its own set of risks. Improperly sharing sensitive legal documents via email can expose them to cyber threats such as hacking, interception, phishing, and unauthorized access. Even simple mistakes, like sending an email to the wrong recipient, can result in significant breaches of confidentiality.
How to Securely Email Documents for Legal Purposes
This blog aims to guide you through the best practices, tools, and strategies for securely emailing legal documents. By following these steps, you can protect your communications, safeguard client trust, and maintain compliance with privacy laws and industry standards. Let’s explore how to ensure your emails remain as secure as possible.
Risks of Sending Legal Documents via Email
Sharing legal documents via email may seem convenient, but it comes with significant risks that could compromise sensitive information. Understanding these risks is the first step toward adopting secure practices. Here are the primary threats to be aware of:
1. Data Breaches
Data breaches are among the most alarming risks, where attackers gain unauthorized access to vast amounts of private information. High-profile cases, such as the breaches at major law firms, have exposed sensitive client data, resulting in lawsuits and reputational damage. These incidents often occur due to weak email security, making legal professionals and their clients prime targets.
Example: In 2016, the Panama Papers scandal revealed how over 11 million documents from a law firm were leaked, exposing financial secrets of powerful individuals worldwide. Although this breach involved multiple factors, email vulnerabilities were a critical component.
2. Interception
Emails travel through multiple servers and networks before reaching the intended recipient, making them susceptible to interception by hackers. Without encryption, emails can be read during transit, exposing sensitive legal documents such as contracts, evidence, or client correspondence.
How it Happens: Hackers often use techniques like man-in-the-middle (MITM) attacks to intercept emails, particularly on unsecured networks like public Wi-Fi. These attacks allow bad actors to access confidential information without the sender or recipient realizing it.
3. Phishing Scams
Phishing attacks exploit email communication by tricking recipients into revealing sensitive information or opening malicious attachments. Legal professionals, who routinely handle high-value data, are often targeted with emails that appear legitimate but are designed to compromise security.
Example: A hacker might impersonate a client or colleague, requesting a legal document to be emailed to a seemingly familiar address. Once shared, the information is in the hands of the attacker. Even worse, opening infected attachments can introduce malware to your system, enabling further breaches.
4. Unauthorized Access
Even if an email reaches the intended recipient, there’s no guarantee the document will remain secure. Emails can be forwarded, downloaded, or shared with unintended parties without your consent. This creates a chain of unauthorized access that is difficult to control.
Real-Life Scenario: Consider a situation where a legal document is mistakenly forwarded to someone outside the legal team. Even if the mistake is realized, the recipient could save or share the document, leading to a confidentiality breach. Additionally, poor access controls in shared email accounts can amplify this risk.
Best Practices To Securely Email Documents for Legal Purposes
To ensure your legal documents remain protected during email communication, it's crucial to implement security measures that safeguard against unauthorized access and cyber threats. Here are the best practices for securely emailing sensitive legal documents:
1. Use Encrypted Email Services
Encryption is the cornerstone of secure email communication. End-to-end encryption ensures that only the intended recipient can access the email's contents, preventing hackers or third parties from intercepting and reading the data during transmission.
What is End-to-End Encryption? End-to-end encryption scrambles your email's content into an unreadable format that only the recipient's email client can decrypt.
Recommended Encrypted Email Providers:
Continia: Offers robust end-to-end encryption and zero-access encryption for emails and attachments.
Tutanota: Focuses on privacy with built-in encryption for emails, calendars, and contacts.
Zoho Mail: Provides secure, encrypted email services tailored for businesses.
Tip: Encourage your recipients to use encrypted email services as well to ensure both ends of communication are secure.
2. Password-Protect Attachments
Adding a password to your attachments provides an additional layer of security. Even if an email is intercepted, the document remains inaccessible without the password.
How to Create Secure Passwords:
Use at least 12 characters, including uppercase and lowercase letters, numbers, and special characters.
Avoid using easily guessable information, like names, dates, or dictionary words.
Use a password manager to generate and store strong passwords.
Tools for Encrypting PDFs or ZIP Files:
PDF Encryption: Adobe Acrobat, Smallpdf, or iLovePDF offer options to add passwords to PDF files.
ZIP File Encryption: Tools like WinRAR, 7-Zip, and macOS Finder provide options to compress and password-protect files.
Best Practice: Share the password through a separate communication channel, such as a secure messaging app or a phone call, to avoid email interception.
3. Enable Two-Factor Authentication (2FA)
Two-factor authentication adds an extra layer of security to your email account by requiring a second verification step, such as a code sent to your phone, in addition to your password.
Importance of 2FA: Even if someone manages to steal your password, they won’t be able to access your account without the second factor.
Steps to Enable 2FA on Popular Platforms:
Gmail: Go to "Security" in your Google account settings, and enable "2-Step Verification."
Outlook: Enable "Two-Step Verification" under the "Security settings" of your Microsoft account.
ProtonMail: Activate "Two-Factor Authentication" in the "Security" section of your ProtonMail account.
Tip: Use an authenticator app, like Google Authenticator or Authy, for added security over SMS-based codes.
4. Limit Access
Restricting who can view or access your shared documents minimizes the risk of unauthorized access.
Share with Necessary Recipients Only: Send legal documents only to individuals who require access. Double-check email addresses before hitting "send."
Set Expiration Dates for Shared Documents: Platforms like Google Drive, Dropbox, and OneDrive allow you to set time-limited access to shared files, ensuring they are not accessible indefinitely.
Tip: Use tools that offer "view-only" permissions or prevent downloads to further control document access.
5. Secure Your Network Connection
A secure internet connection ensures that your email and documents cannot be intercepted during transmission.
Avoid Public Wi-Fi: Public Wi-Fi networks are vulnerable to eavesdropping attacks. If you must use one, avoid sending sensitive information.
Use a Virtual Private Network (VPN): A VPN encrypts your internet connection, making it harder for hackers to intercept your emails. Recommended VPNs include NordVPN, ExpressVPN, and Surfshark.
Tip: Always ensure your VPN is enabled before accessing your email or sharing sensitive documents over the internet.

Consider using a password manager like LastPass or 1Password to create and store complex passwords securely.
3. Failing to Verify Recipient Information
Sending an email to the wrong recipient is a simple but costly mistake, potentially exposing sensitive information to unintended parties.
How to Avoid:
Double-check email addresses before sending.
Use email services that allow recall of messages or set restrictions on forwarding.
4. Ignoring Two-Factor Authentication (2FA)
Not enabling 2FA on email accounts leaves them vulnerable to unauthorized access, even if the password is compromised.
How to Avoid: Enable 2FA for your email account and encourage others in your organization to do the same.
5. Sharing Sensitive Information Over Public Wi-Fi
Public Wi-Fi networks are often unencrypted and vulnerable to attacks, making it easy for hackers to intercept emails.
How to Avoid:
Avoid using public Wi-Fi for sending sensitive emails.
Use a VPN to encrypt your connection when accessing emails on public networks.
