1.   Where a payment order is initiated directly by the payer, the payer’s payment service provider shall, without prejudice to Article 71, Article 88(2) and (3), and Article 93, be liable to the payer for correct execution of the payment transaction, unless it can prove to the payer and, where relevant, to the payee’s payment service provider that the payee’s payment service provider received the amount of the payment transaction in accordance with Article 83(1). In that case, the payee’s payment service provider shall be liable to the payee for the correct execution of the payment transaction.

Where the payer’s payment service provider is liable under the first subparagraph, it shall, without undue delay, refund to the payer the amount of the non-executed or defective payment transaction, and, where applicable, restore the debited payment account to the state in which it would have been had the defective payment transaction not taken place.

The credit value date for the payer’s payment account shall be no later than the date on which the amount was debited.

Where the payee’s payment service provider is liable under the first subparagraph, it shall immediately place the amount of the payment transaction at the payee’s disposal and, where applicable, credit the corresponding amount to the payee’s payment account.

The credit value date for the payee’s payment account shall be no later than the date on which the amount would have been value dated, had the transaction been correctly executed in accordance with Article 87.

Where a payment transaction is executed late, the payee’s payment service provider shall ensure, upon the request of the payer’s payment service provider acting on behalf of the payer, that the credit value date for the payee’s payment account is no later than the date the amount would have been value dated had the transaction been correctly executed.

In the case of a non-executed or defectively executed payment transaction where the payment order is initiated by the payer, the payer’s payment service provider shall, regardless of liability under this paragraph, on request, make immediate efforts to trace the payment transaction and notify the payer of the outcome. This shall be free of charge for the payer.

2.   Where a payment order is initiated by or through the payee, the payee’s payment service provider shall, without prejudice to Article 71, Article 88(2) and (3), and Article 93, be liable to the payee for correct transmission of the payment order to the payment service provider of the payer in accordance with Article 83(3). Where the payee’s payment service provider is liable under this subparagraph, it shall immediately re-transmit the payment order in question to the payment service provider of the payer.

In the case of a late transmission of the payment order, the amount shall be value dated on the payee’s payment account no later than the date the amount would have been value dated had the transaction been correctly executed.

In addition, the payment service provider of the payee shall, without prejudice to Article 71, Article 88(2) and (3), and Article 93, be liable to the payee for handling the payment transaction in accordance with its obligations under Article 87. Where the payee’s payment service provider is liable under this subparagraph, it shall ensure that the amount of the payment transaction is at the payee’s disposal immediately after that amount is credited to the payee’s payment service provider’s account. The amount shall be value dated on the payee’s payment account no later than the date the amount would have been value dated had the transaction been correctly executed.

In the case of a non-executed or defectively executed payment transaction for which the payee’s payment service provider is not liable under the first and second subparagraphs, the payer’s payment service provider shall be liable to the payer. Where the payer’s payment service provider is so liable he shall, as appropriate and without undue delay, refund to the payer the amount of the non-executed or defective payment transaction and restore the debited payment account to the state in which it would have been had the defective payment transaction not taken place. The credit value date for the payer’s payment account shall be no later than the date the amount was debited.

The obligation under the fourth subparagraph shall not apply to the payer’s payment service provider where the payer’s payment service provider proves that the payee’s payment service provider has received the amount of the payment transaction, even if execution of payment transaction is merely delayed. If so, the payee’s payment service provider shall value date the amount on the payee’s payment account no later than the date the amount would have been value dated had it been executed correctly.

In the case of a non-executed or defectively executed payment transaction where the payment order is initiated by or through the payee, the payee’s payment service provider shall, regardless of liability under this paragraph, on request, make immediate efforts to trace the payment transaction and notify the payee of the outcome. This shall be free of charge for the payee.

3.   In addition, payment service providers shall be liable to their respective payment service users for any charges for which they are responsible, and for any interest to which the payment service user is subject as a consequence of non-execution or defective, including late, execution of the payment transaction.
