If the visitation is court ordered and the non-compliant parent can provide no compelling and acceptable reasons why they are not adhering, yes.
It the non custodial parent alters the court ordered visitation, the other parent does not have to allow the visitation, unless it was altered in court. If it was not altered in court, the parent can file for contempt of court.
