Joint Legal Custody

When parents have joint legal custody do both parents have control over a child being left alone with no supervision for several hours? One parent thinks it is ok at their home during their custodial visit and the other parent does not agree does the parent that disagrees have any legal rights to prevent this? The child is 11.

It depends on what your custody agreement or ordersays with respect to decision making. Most likely though your remedy via the legal system would be to file for modification of custody based on a substantial change in circumstances, that you feel that the child is being endangered by being left home alone.
