There are reasons why the non-custodial parent does not share custody. This will have to be looked at by Family and Children's Service because the child's welfare is the primary concern. This poor child has one parent brain dead from a drug overdose and the other parent did not share custody. I hope there are grandparents standing by.
if the custodial patent is brain dead the other parent have full rights to that child custodial parent means that the kids live with them but you as the other parent is just as involved with the kids however there family members may try to fight it
