Typically, a false allegation of abuse leads the offending parent to get the child involved in therapy with a therapist who is sympathetic to that parent’s narrative. If possible, talk with the child’s therapist to set the record straight about the falseness of the allegation.
That last sentence sounds nice but in practice some default processes by the court can make that communication difficult to accomplish.
When we separated my then-spouse was facing a Threat of DV case and I was issued a TPO for the duration of that case granting me protective possession of the home. She then went to family court and managed to get a "standard" temp order awarding her temp custody and majority time of our preschooler. So I was locked out of custody and I got only long alternate weekends and an evening in between.
Unknown to me, she sought therapy for him at a county counseling agency. I found out when our insurance notified me of the 3 month recertification. I politely went there but they refused to discuss anything, telling me to make a written request, which I did, explaining the circumstances and offering to work with them. The written reply was to refuse because I was "likely to be a
danger to the patient or family".
I mean, we had a "standard" temp order where dad got the typical alternate weekends - mine was 72 hours so clearly court didn't imagine was was a danger to him - but I couldn't even talk to the agency or counselor?
They obstructed me during the entire two years of temp orders because my stbEx refused to permit it. All because the temp order assigned her "temp custody", I was locked out at her discretion. Toward the end they relaxed their rules a bit to visit during his Head Start classes... but only after the Custody Evaluator discussed the matter with them.
