A custodial parent cannot deny the noncustodial parent their court-ordered visitation. Visitation is the right of the parent, and it cannot be taken away by the other parent or the child themselves. If you are denied your court-ordered visitation, then reach out to trusted child custody lawyers to enforce your right to have visitation with your child.
If you are the custodial parent and have concerns about following the visitation orders, then you should also speak with a Texas child custody lawyer for more information on what you can do to further protect your child.
