Often we are asked by separated or divorced parents, who are vacationing with their children overseas under the terms of their temporary orders or final judgments, whether a parental consent form or permission letter signed by the non-traveling parent is required. Although the United States does not formally require this documentation, we recommend that the traveling parent obtain such a signed and notarized consent form from the non-traveling parent, and that the agreements we draft contain a provision that obligates the non-traveling parent to provide such a consent form upon request from the traveling parent.
