A child in the state of Alabama can not opt out of visitation with the non custodial parent until the age of 18. If the child is persistent in the fact that they wish visitation to end, this needs to be ordered by a judge of the court.
When the child is 18.
if the child doesn't want to see the noncustodial parent he doesn't have too. don't force him to do it =)
You have to be 18.
Generally, not until the child is 18.
If there is no court mandated agreement that ensures the noncustodial parent visitation rights, then yes they can.
The one who would be responsible for the child during that time which would be the non custodial parent.
