If you are submitting a request on behalf of a minor child or a person under guardianship, you must also deliver a certificate of child custody obtained from the Population Information System. The request must align with the child’s presumed will and serve the child’s best interests. In cases of joint custody, the request must be made and signed by both guardians.
