There is no single “European declaration” that solves every route. The child needs a valid travel document, while parental-consent rules may differ between Bulgaria, transit countries, destination and carrier.
Verification matrix
- Level: Bulgaria · What to verify: Document and exit requirements · Where: Foreign Ministry/Border Police
- Level: Destination · What to verify: Extra consent or form · Where: Official authority/consulate
- Level: Transit · What to verify: Every country on the route · Where: Official authority/consulate
- Level: Carrier · What to verify: Its own form and rules · Where: Airline, railway or other carrier
1. The child’s document
Your Europe says children need their own valid passport or identity card as applicable. Check:
- validity on outbound and return dates;
- acceptance in every country;
- dual-nationality rules;
- name matching the booking;
- any visa requirement.
Do not treat a birth certificate or a parent’s document as a substitute for the travel document.
2. Who accompanies the child
Classify the case: both parents, one parent, another adult or independent travel. Your Europe warns that travel with one parent, without a legal guardian or alone may require an extra official consent document. There is no single EU rule.
3. The Bulgarian side
The Bulgarian Ministry of Foreign Affairs points to Border Police information and provides declarations for a child travelling alone or with an accompanying adult.
For travel with a teacher, coach or group leader, the ministry recommends that a notarised authorisation cover both consent and explicit authority if a Bulgarian document is lost, stolen, damaged or destroyed, allowing the adult to assist with a temporary passport.
Permission to depart and the ability to respond to a lost document are not the same.
4. Destination and transit
Your Europe explicitly notes that a transit country may request authorisation even if the destination does not. For each country, record:
- original or copy;
- notarisation;
- translation and language;
- deadline or prescribed form;
- different-surname rules;
- proof of sole parental responsibility where applicable.
If unclear, contact the embassy or consulate. This is a checklist, not legal advice.
5. The carrier
An airline may have its own form or unaccompanied-minor service. Check the minimum age, who hands over and collects the child, required originals, and rules for connections and partner-operated flights. Retain the terms that applied when booking.
6. One document folder
Prepare:
- valid travel document;
- originals of applicable declarations;
- backup copies;
- birth certificate, court decision or other document when needed;
- parent/guardian and consular contacts;
- bookings and accompanying-adult details.
A digital copy is useful backup but not a guaranteed substitute for an original.
7. Recheck
Your Europe warns that national rules may change without notice. Check after booking and again in the final days before departure.
Checklist
- [ ] The child has their own valid document.
- [ ] The accompanying person is clear for every segment.
- [ ] Bulgaria, destination and transit are checked.
- [ ] Carrier rules are checked.
- [ ] Translations, notarisation and originals are prepared.
- [ ] Backup copies and consular contacts are available.
- [ ] A final recheck is complete.
The key principle
Do not search for one document that “works everywhere”. Build evidence for every control point: Bulgaria, transit, destination and carrier.
