Frequently Asked Questions: 

  • QUESTION: Do the Rules of Professional Conduct require Missouri attorneys to use an email disclaimer warning clients who are recipients that email is not a secure form of communication?

ANSWER: The Rules of Professional Conduct do not require an attorney to use a disclaimer on emails sent to clients. As with any form of communication with clients, attorneys must take reasonable precautions to prevent the unintended interception of confidential information. Special circumstances or the need to transmit highly sensitive information may require special security measures in order to comply with Rule 4-1.6. See Informal Opinion 2012-01.

  • QUESTION: Are there any Rules of Professional Conduct specifically governing internet advertising and internet communication about a lawyer’s services?

ANSWER: In the course of internet communications regarding a lawyer’s services,  a Missouri lawyer must comply with Rules 4-7.1 – 4-7.5.  See Informal Opinion 970038.
