I recently had someone call to ask about getting text messages from a phone company. This comes up often with regard to allegations of adultery, and I found the below article.
The gist is that some companies keep the actual data (text) sent, but most only keep the information regarding who sent and who received those text messages.
Don’t let this stress you! Most of the time, parties are only looking for this information to prove adultery, which can be done with other tools and methods. Once adultery is established by evidence, the party has done all they need to do to have the Judge take that action into consideration. Those added texts probably will not have that much more effect than the evidence already presented.
