The persons mentioned in Article L. 561-2 shall refrain from carrying out any transaction involving sums which they know, suspect or have good reason to suspect originate from an offence punishable by a custodial sentence of more than one year or are linked to the financing of terrorism until they have made the declaration provided for in Article L. 561-15. They may then proceed with the transaction only if the conditions set out in the fourth paragraph of Article L. 561-24 are met.
When a transaction that is required to be reported under Article L. 561-15 has already been carried out, either because it was impossible to postpone its execution, or because its postponement could have hindered investigations into a suspected money laundering or terrorist financing transaction, or because it became apparent after it had been carried out that it was subject to this report, the person mentioned in Article L. 561-2 shall inform the department provided for in Article L. 561-23 without delay.
