This practical guide explains the Greek legal framework in plain language for readers who need to understand the issue before speaking with a lawyer.

The practical question is what should be checked first, which deadline can change the outcome and which evidence should be kept before the dispute escalates.

For this topic, the key legal points are:

  • The user must notify the payment service provider as soon as an unauthorised transaction is noticed and within the legal time limit.
  • The provider carries an important burden of proof regarding authentication, recording of the transaction and absence of technical malfunction.
  • The mere use of card data or codes does not by itself settle liability; the facts and security measures matter.

Keep contracts, official notices, payment records, screenshots, platform messages and correspondence. In Greek legal practice, the sequence of events often decides the next step.

If the matter is urgent, speak with a lawyer before signing, paying, accepting a settlement or missing a procedural deadline.
