In a civil lawsuit that I am not a part of, my cell phone records have been subpoenaed by the lawyer of one of the parties. The subpoena did not give a reason or justification for why they wanted my cell phone records. My question is this, do have I have to provide them with my cell phone records when I am not even a part of this lawsuit? I thought phone calls are considered personnel and private as long as no criminal act is being committed. Also, with my cell phone records they could reveal client names and numbers that are part of my husband’s private business which I feel they do not have a right to, and is also not a part of this lawsuit. What should the proper and legal response be back to this firm without breaking the law and without giving up my cell phone records? Thanks.
