Request a "No Third Party interference order" that prohibits GF from doing this. I have gotten them in the past to prohibit a SO from representing themselves as the child's parent when they aren't.
Thank You!
My attorney sent a quick message cause she's in court and said she'll put the No Third Party Interference in her notes at the top and that she won't include the failure to pay child support because her husband is a supervisor in the CSEA office and that it would be a first appearance anyway advising him of his right to an attorney. She said that I do need to bring her the paperwork so she can include it as evidence that he does not have our S5's best interests in mind.
