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.
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."
If the child is not accompanied by both parents, we recommend carrying a consent letter signed by the non-accompanying parent, regardless of the parents' marital status (single, married, common-law, separated, divorced or never married).
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.

Tips for an Effective Child Permission Letter List important information about your child and any other relevant info. Mention the scope of what you are/aren't permitting. Note what time period the authorization applies for. Include your contact info and sign your name with a witness present.
