• receive a medical document request to transmit the medical document to a second healthcare entity, wherein the medical document request includes at least one of a C-move command and a C-find command;
• determine, based on the medical document request, whether a legal document is required approve the medical document request;
• send, in response to determining that the legal document is required to approve the medical document request, a legal document request to a legal entity associated with , and authorized as a legal representative of, the patient;
• receive a legal document responsive to the legal document request;
• determine that the legal document responsive to the legal document request fulfills the legal document request;
