Again, it's complicated. Ella has agency and that's what complicates this. Elsie is also highly influenced by her and AE too.
Of course, as any parent knows, as children get older it can be difficult to make them do something they absolutely refuse to do. California courts have acknowledged this dilemma. In one case, a trial judge held a mother in contempt of court because her 14 year old daughter refused to visit with her father, in violation of the existing visitation order. But a higher court overturned that decision, citing the daughter's age and her "strong wishes" not to visit with her father, as well as a lack of evidence that the mother had the ability to force the teenager to obey the visitation order. (Coursey v. Superior Court (Coursey), 194 Cal.App.3d 147 (Cal. Ct. App. 1987).) This is why I fear it may be too late for IG. Too little was done too late, the PA rot set in and Ella will soon be 14. But at least he can say he fought hard for them, if they try to reproach him as adults. I just hope Judge Josh says he doesn't have to pay child support if he can't see the kids, or waives all AE's spousal support. She needs to be punished for what she did.
