The accounting officer may make payments by bank credit transfer only if the payee’s bank account details and information confirming the payee’s identity, or any modification, have first been entered in a common file by institution.

Any such entry in the file of the payee’s legal and bank account details or modification of those details shall be based on a supporting document, the form of which shall be defined by the accounting officer.

With a view to payment by bank credit transfer, authorising officers may enter into a commitment towards a third party on behalf of their institution only if that third party has provided the documentation required for its entry in the file.

Authorising officers shall inform the accounting officer of any change in the legal and bank account details communicated to them by the payee and shall check that these details are valid before a payment is made.

In connection with pre-accession aid, individual commitments may be concluded with the public authorities in the countries applying for accession to the European Union without a prior entry in the third-party file. In such cases the authorising officer shall do his utmost to ensure that the entry is made as quickly as possible. The agreements shall provide that communication to the Commission of the payee’s bank account details is a condition to be fulfilled before the first payment can be made.
