A letter of consent, preferably in English and notarized, from the other parent or signed by both custodial parents. The letter should say: "I acknowledge that my child is traveling outside the country with the name of the adult with my permission."
A parent generally needs permission from the other parent before travelling with the child especially if the travel will impact the parenting time of the other parent. However, if the separation agreement dictates how travel should occur, both parents are expected to follow the terms of the agreement.
In the USA, though, unless there's a court order requiring permission from both parents, a child may travel (even to overseas) with either parent/guardian without showing proof of permission from the other parent.
Contact A Notary Public: After drafting your letter, reach out to a local notary public or use online services like NotaryCam. Presentation For Verification: Present yourself along with identification documents before signing under oath in front of them.
Most Consent to Travel documents can be drafted by the notary or by the parents. It needs to contain identifying details for each parent and child, as well as details of travel. It should also contain express consent and permission by the parent that the child can travel.
The legal parent/legal guardian who cannot apply with the child can give consent using this form or a written statement that includes all of the information on this form. This form or the written statement must be notarized.
