18. Until then, if the parent has court-ordered visitation, it has to be followed. If there is a legitimate reason the child does not want to visit the parent, the custodial parent can petition the court to revise the visitation order.

If the parent has court-ordered visitation, yes. If there is a legitimate reason the child does not want to visit the parent, the custodial parent can petition the court to revise the visitation order.
