1. Member States shall take the necessary measures to ensure that the persons affected by the measures provided for under this Directive have the right to an effective remedy and a fair trial in order to uphold their rights.

2. Member States shall take the necessary measures to ensure that the freezing order is communicated to the affected person as soon as possible after its execution. Such communication shall indicate, at least briefly, the reason or reasons for the order concerned. When it is necessary to avoid jeopardising a criminal investigation, the competent authorities may postpone communicating the freezing order to the affected person.

3. The freezing order shall remain in force only for as long as it is necessary to preserve the property with a view to possible subsequent confiscation.

4. Member States shall provide for the effective possibility for the person whose property is affected to challenge the freezing order before a court, in accordance with procedures provided for in national law. Such procedures may provide that when the initial freezing order has been taken by a competent authority other than a judicial authority, such order shall first be submitted for validation or review to a judicial authority before it can be challenged before a court.
