Waste of time. Nothing is required. |
Nothing special. I travel with my two kids who have a different last name and there haven’t been any questions, yet. They are old enough to answer questions if necessary |
In the mode of “better safe than sorry” you should have a notarized letter from the child’s other parent when traveling internationally. This is because in some cases officials may be concerned that you are trying to take a child out of the country permanently to prevent the other child’s parent from having access. I have never needed it, but I do know one person who was asked. |
