Either one of the child’s parents, or their legal guardian may submit a passport application. It is not necessary that both of the parents sign the application, however, the Passport Program may contact the other parent if they have not signed the document.
It is important to note that in cases where one parent has custody of a child, they must be the parent to apply for the passport. In this scenario, be sure to have copies of your separation agreement or court orders that outline the custody arrangement.
Finally, children over 16 are considered adults, and are required to submit their own passport application.
