Yes. When you travel with your children, and the other parent is not traveling with you, it is important to prove to the officials that you are traveling with the consent of the other parent. A “consent to travel” form is often requested by airlines and customs & immigration officials. If you do not have this form, you may be prohibited from traveling until this form is completed by the non-traveling parent.
There is no official form which must be used. However, the key is to have the Consent signed in front of a Commissioner for Oaths, which may be found at banks, real estate offices, law offices, insurance agencies, and other similar offices.
If you are in need of a Consent, it is the non-traveling parent who must sign the form. It is a very simple step to take, but can avoid a whole lot of hassle when you are travelling.
