What can I file, in the state of Texas, to have my name and personal information and details removed from a custody case my spouse is involved in. I am not the child's biological parent and have no "legal custody" ties to this child or this matter. My spouse's attorney originally told me that I would not have to provide personal information, financial information, or about my family and yet I am having to. My stance on this has no legal relevance to resolving this custody case. What can be said or done about this? I need to protect myself and guard myself before this goes on much longer.
This sounds like something that you should talk over with the spouse's lawyer.
There is nosuch thing as "removing information" from a custody case.
It sounds as if somebody is in the process of responding to pre-trial discovery. You have the option of answering an interrogatory thus: "Objection; irrelevant."
In a custody case, we are interested in the stepparent to the extent that she may have a criminal history, or be a psychopath or a drug abuser.
