A minor traveling abroad: what documents are required and when is parental consent needed?

When travelling abroad with a child, a common question arises: is a passport or ID card sufficient, when is the other parent's consent required, and must the consent be notarised?

There is no single answer for all countries. The requirements depend on the destination, transit countries, who the child is travelling with, and sometimes also the rules of the airline, ferry company or other carrier. Therefore, it is worth checking the documents when planning the trip, rather than waiting until you are at the airport.

Does the child need their own passport or ID card?

Yes. Every child, regardless of age, must have their own valid travel document. The Estonian Ministry of Foreign Affairs' Reisi Targalt emphasises that a birth certificate is not a travel document and does not replace a passport or ID card.

This also applies to infants—a child cannot simply be “included” in a parent's travel document when travelling abroad.

When is a ID card sufficient?

An Estonian citizen can travel to many European countries with a valid ID card. This includes, among others, the countries of the European Union and the European Economic Area, as well as Switzerland, but the ID card is also accepted as an Estonian citizen's travel document in several other European countries.

The exact list and travel document validity requirements can be checked on the Välisministeeriumi website Check travel documents.

Important: do not automatically assume that “Europe means an ID card” and “outside EL means a passport”. Countries' rules vary and must be checked for the specific destination.

When is a passport required?

When travelling outside Europe, the main travel document for an Estonian citizen is a passport. Some countries additionally require the passport to remain valid for several months after the planned end of the trip.

For example, the validity requirement may be three or six months after leaving the country. Therefore, it is not enough for the passport to still be valid on the day of the flight.

Before travelling, check the conditions for the specific country on the Reisi Targalt destinations page or, if necessary, ask the destination country's embassy.

When is parental consent required?

This particular question causes the most confusion.

In the European Union, there is no single rule requiring a child travelling with one parent or without their parents to have the same form of consent in every country. Each country may impose its own requirements.

The European Commission's portal Your Europe points out that additional permission from a parent or guardian may be required if the child is travelling:

• alone;
• with only one parent;
• with an adult who is not their parent or legal guardian.

In addition, consent may be required in a transit country even if the final destination does not require it.

If the child is travelling with only one parent

If a mother or father is travelling alone with the child, it is advisable to obtain the consent of the other parent with custody rights before the trip.

Reisi Targalt recommends carrying consent when travelling with a child even if only one parent is travelling. Whether simple written consent is sufficient or a notarised document is required depends on the requirements of the countries being visited and transited.

If the parent and child have different surnames, it may also be useful to bring an English-language extract from the population register or another document showing the relationship between the parent and child.

If the child is travelling with a grandparent, relative or another adult

If the child is travelling with, for example, a grandmother, grandfather, coach, teacher, family friend or another adult who is not their legal representative, particular attention must be paid to the issue of consent.

Reisi Targalt recommends bringing the parents' joint written consent in English in this case.

The consent form should include at least:

• the child's name and personal details;
• the details of the travelling adult;
• travel destination or destinations;
• travel period;
• contact details of the parents or guardians;
• the signatures of the parents or guardians.

The Ministry of Foreign Affairs has also published a sample consent form for travelling with a child as a PDF file.

Does the consent need to be notarised?

Not always. For some countries, a simple written consent signed by a parent is sufficient, while others may require a notarised document or additional evidence.

Therefore, it is not advisable to prepare a single “universal” consent form and assume that it will be accepted everywhere.

Check before travelling:

1. the requirements of the destination country;
2. the requirements of all transit countries;
3. the terms and conditions of the airline, ferry, bus or train company.

Also, Your Europe recommends checking the airline’s rules separately when travelling by air, as carriers may have their own forms and requirements.

If the child is travelling completely alone

For a minor travelling alone, checking only the country's border-crossing rules is not enough. It is also very important to check the age restrictions of the specific transport operator.

For example, Lux Express allows unaccompanied travel on its international routes from the age of 12 and requires minors travelling alone to have parental consent including contact details.

Airline terms may differ—some airlines have a separate service and age restrictions for unaccompanied minors.

Should you take the birth certificate with you when travelling?

A birth certificate does not replace a passport or ID card, but in certain situations it may be a useful supporting document.

For example, if:

• the child and the parent travelling with them have different surnames;
• it is necessary to prove the family relationship between the child and the parent;
• the destination country or carrier requires additional proof.

Reisi Targalt also recommends using an English-language extract from the population register, if necessary, showing the details of the parents with custody rights.

6 things to check before a child travels abroad

1. Check the validity of the child's passport or ID card

Do not leave this until the final week. Check both the document's expiry date and any additional validity period required by the destination country.

2. Check the requirements of destination and transit countries

If the flight includes a connection or the journey passes through several countries, the requirements of those countries must also be checked.

3. Find out whether parental consent is required

This is particularly important for a child travelling with one parent, with a grandparent, with a group, or completely alone.

4. Check whether simple written consent is sufficient

Some countries may require a notarised document. If necessary, check the requirement with the country's embassy or consulate.

5. Check the carrier's rules

Airlines, bus companies and ferry companies may impose their own age restrictions, consent forms or rules for unaccompanied children.

6. Keep important documents in your hand luggage

The passport, ID card, consent form and any other required supporting documents should be readily accessible throughout the trip, not in checked baggage.

Common mistakes when travelling abroad with children

The child's document is checked too late.
A valid passport does not always mean that it meets the destination country's validity requirement.

It is assumed that a birth certificate is sufficient.
It is not. The child needs their own valid travel document.

It is assumed that no document is needed in the Schengen Area.
The absence of border controls does not mean that the travel document can be left at home.

The need for consent is checked only according to the destination country.
Requirements may also apply in transit countries.

The rules of the airline or another carrier are overlooked.
The carrier may ask for documents that are not specifically required by the destination country's general border regulations.

It is automatically assumed that the consent must be notarised.
This depends on the specific country. In some cases, simple written consent is sufficient; in others, it is not.

Frequently asked questions

Can a child travel abroad with only a ID card?

It depends on the destination country. An Estonian citizen can travel to many European countries with an ID card, but an ID card is not sufficient for every country. Check the requirements for the specific destination before travelling.

Does a child always need the other parent's consent when travelling with only one parent?

There is no uniform rule that applies throughout the European Union. Consent may be required by the destination country, a transit country or the transport company. Therefore, when travelling with one parent, it is advisable to always check before the trip whether consent is required and, if necessary, bring the document with you.

Does the parent's consent have to be notarised?

Not necessarily. In some countries, simple written consent is sufficient, while in others notarisation may be required. The requirements must be checked for the destination and transit countries.

Can a birth certificate replace a passport?

No. A birth certificate is not a travel document. In certain situations, it may be used as an additional document to prove the family relationship.

Does an infant also need their own travel document?

Yes. Regardless of age, a child must have their own valid travel document for travelling abroad.

What should you do if a child is travelling with a grandparent?

Check the requirements of the destination and transit countries and prepare the parental consent. Reisi Targalt recommends that, in such a situation, the child's parents provide joint written consent in English.

Summary

When a minor travels abroad, simply buying a plane ticket is not enough. First, make sure that the child has a passport or ID card that is suitable for the destination country and has sufficient remaining validity.

If a child travels with one parent, without their parents or with another adult, the parental consent requirements must also be checked. In some cases, a simple written authorisation is sufficient, while in another country a notarised document may be required. Airlines, bus companies and ferry operators may also impose their own conditions.

The safest approach is to check the destination country, transit countries and carrier separately. A few minutes spent checking official requirements can prevent a very unpleasant surprise at the airport or border.
