In criminal law, kidnapping is the unlawful taking away or transportation of a person against that person's will, usually to hold the person unlawfully. This may be done for ransom or in furtherance of another crime, or in connection with a child custody dispute. In some countries such as the United States a large number of child abductions arise after separation or divorce when one parent wishes to keep a child against the will of the other or against a court order. In these cases, some jurisdictions do not consider it kidnapping if the child, being competent, agrees.
