Can a custodial parent refuse visitation if the father is threatening not to return children after visitation?

Yes, a custodial parent can refuse visitation if they have legitimate concerns for the children's safety, such as threats from the other parent about not returning them. It is crucial to document any threats and communicate with legal authorities, as the court may need to be involved in modifying visitation arrangements. However, the custodial parent should seek a legal solution rather than unilaterally denying visitation, as this could lead to legal repercussions. Consulting with a family law attorney is advisable in such situations.
