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."
It's important that you give your co-parent notice and preferably get their express permission in writing if you wish to travel outside the state with your child. If the other parent refuses to cooperate, you can ask for the court's permission in advance.
In general, either parent can take their child wherever they wish within state lines before their divorce has been finalized. If the trip in question is outside the state of Illinois, the parent who wants to go on the trip needs to get the other parent's written consent for this.
A consent letter is recommended for all cross-border travel, even for a day trip, if the child will be travelling alone, with only one parent, with friends or relatives or with a youth group.
Out-of-State Travel with Illinois Children Illinois law requires each parent who is part of a child custody agreement to retain the other parent's consent before traveling out of Illinois with the children for vacation. Parental consent is not required for in-state travel.
File a motion asking for expedited ruling and contact the judge's clerk, explain that you want to leave today for a trip on your parenting time and the other parent is unreasonably withholding consent, and ask if there is any way that the judge can rule today.
If you think the other parent plans to keep the child from you, you can ask the court for an emergency order. Among other things, it could give the court power to confiscate the child's or parent's passport if that parent tries to take the child out of the country.
