I linked to this (information about emancipation of a minor in Arizona
Emancipation of a Minor) back when we read in the CV divorce filing about (paraphrasing, not a direct quote) "Mother and Father's other children are emancipated." With all the talk of family trusts here, is it possible there was money for Tylee/in Tylee's name that would allow her to establish that she could support herself on her own? Her GED would also be considered, as well as parent permission. Is there a reason Lori would want Tylee to be emancipated? One more "adult" to funnel money to/who can buy property/etc.? Or, if she wanted to emancipate on her own and could prove her guardians' environment wasn't safe. Interesting question? But there was that other discrepancy in the divorce filing about whether Lori had been to the mental health agency, so maybe it was just a discrepancy.
The other reason I doubt Tylee is emancipated is that she is part of this search and named as a missing child. If she truly were emancipated, Lori could just tell LE, "Tylee's emancipated."
