Do you need notarized parental consent for a minor traveling out of Turkey with only one parent or a grandparent?

If a child has a formal exit restriction linked to a parent (e.g. custody dispute), border officers cross-check the system and may deny exit regardless of invitations from Turkish-citizen relatives — this needs direct confirmation with a lawyer or consulate, not just an invitation letter.

When traveling with a grandparent or other relative, notarized consent from BOTH parents is required, even if the child and adult share the same surname — a matching surname alone isn't accepted as proof.

When one parent travels with an older minor (e.g. 17 years old), Turkish rules still formally require consent from the other parent (including an ex-spouse) — age doesn't waive the requirement.

Consent must be notarized, translated into Turkish, and ideally apostilled if issued outside Turkey — otherwise border officers may reject it.

For a child leaving with a grandparent (even if they entered Turkey with their parents), border control still requires a separate power of attorney/consent from the parents for that specific trip — the previous entry with parents doesn't exempt this.
