Text messages have become a common form of communication, and in Texas criminal cases, they are increasingly used as evidence. According to research, digital communications are admitted in felony cases involving interpersonal crimes, including assault, domestic violence, and DWI. Courts evaluate the authenticity, relevance, and method of acquisition when determining admissibility.
Understanding how text messages can be used and the challenges in defending against them is essential for defendants and their legal teams.

Admissibility of Text Message Evidence in Texas
Texas courts recognize text messages as a form of electronic evidence. However, admissibility depends on several factors:
- Authentication: The message must be proven to originate from the alleged sender
- Relevance: The content must relate directly to the alleged criminal conduct
- Integrity: Messages must be shown to be unaltered and reliable
A criminal defense lawyer in San Antonio can challenge these points to ensure only accurate, verified evidence is considered by the court.
Privacy and Legal Considerations
Privacy laws and Fourth Amendment protections often come into play when text messages are collected. In Texas:
- Law enforcement generally requires a warrant to access private messages from a phone or provider
- Exceptions may exist for messages voluntarily shared with others
- Defendants have a right to challenge evidence obtained through illegal searches
A defense attorney in San Antonio, TX, may argue that improperly obtained messages should be excluded under these legal protections.
Defense Challenges and Strategic Responses
Even when text messages are admissible, defense strategies can mitigate their impact:
- Questioning the context or interpretation of the messages
- Highlighting inconsistencies or contradictions in the evidence
- Presenting expert testimony on digital forensics
- Collaborating with dwi lawyer, dui attorney, or a criminal lawyer for cases involving intoxication or traffic offenses
By addressing authenticity and context, attorneys can reduce the weight of text message evidence in criminal proceedings.
