A Child Travel Consent Form is a legal document that provides permission from a child's parents or legal guardian for the child to travel without them. A letter from the person with parental responsibility for the child is usually enough to show you've got permission to take them abroad.A child travel consent form allows a minor to travel alone or with another person or group. You just need to make a document in some notary that your wife gives you right that you can travel with the kid. No person can take a child (who lives in Scotland) out of the United Kingdom without the consent of both parents. The intention of this letter is to provide consent for a minor child to travel without the company of both legal parents.
