I recommend that you provide a consent form from you for your minor child who is travelling abroad without parents.
If a child travels abroad without being accompanied by his or her parents or one of his or her parents, he or she should be given an informal consent form in addition to the required identification documents. This must state that the legal guardian(s) agrees to the trip abroad.
The consent form should contain the following information:
In case of a name difference, the child should also provide a copy
carry with them.
Depending on the destination country,
You can have the translations done at a translation agency of your choice
let.
A notice:
Some countries do not allow children traveling with only one parent with custody to enter the country without a consent form from the other parent with custody.
You can also find special features of individual destination countries in the travel and
Safety instructions from the Federal Foreign Office. For further information on the respective regulations of the destination country, you can also contact the responsible foreign representation in the Federal Republic of Germany.
