Can a court revoke joint custody rights of a parent who has left the country and remarried there and has stopped paying child support?

Yes, a court can revoke joint custody rights if a parent has left the country, remarried, and ceased paying child support, particularly if these actions negatively impact the child's well-being. The custodial parent may petition the court to modify custody arrangements, demonstrating that the other parent's abandonment and lack of support are not in the child's best interests. The court will consider various factors, including the child's needs and the parent's involvement, before making a decision. However, specific outcomes can vary based on jurisdiction and the details of the case.
