Here in Arizona, I went to a court with a non-JW mom (I met through this site in fact) who went to court about concern that her 3 children could be baptized JW. The judge asked the JW father what age the JWs baptize,,the father said "at age of maturity." The judge asked "at what age is that?" The father said that the child is asked several questions by the elders to determine if they were mature enough. Surprisingly. the judge said then that 'he' would question the children also to determine if they were mature." The judge also required that the mother should receive 90 day notice before any baptism of the children and then she would have to inform the court.
A year later I contacted her to see how things were going. She was happy to say that the kids weren't even going to meetings with their dad. Sounds like to her that the father wasn't going to meetings either, at least not when the kids were with him.
I had never heard of a judge requiring that order before.
The non-JW mom also requested that only the 'father' could have a personal Bible Study with the children and not any elders nor anyone else in the cong. The judge granted that also.
The mom also requested the kids not go to meetings at the Kingdom Hall. Of course, the judge didn't grant that. But in all, I was amazed at what she did accomplish.
