1. When the transfer of the official address results in a change in the law applicable pursuant to Article 2, a transfer proposal must be drawn up, filed and published in accordance with the conditions laid down in Articles 7 and 8.

No decision to transfer may be taken for two months after publication of the proposal. Any such decision must be taken by the members of the grouping unanimously. The transfer shall take effect on the date on which the grouping is registered, in accordance with Article 6, at the registry for the new official address. That registration may not be effected until evidence has been produced that the proposal to transfer the official address has been published.

2. The termination of a grouping's registration at the registry for its old official address may not be effected until evidence has been produced that the grouping has been registered at the registry for its new official address.

3. Upon publication of a grouping's new registration the new official address may be relied on as against third parties in accordance with the conditions referred to in Article 9(1); however, as long as the termination of the grouping's registration at the registry for the old official address has not been published, third parties may continue to rely on the old official address unless the grouping proves that such third parties were aware of the new official address.
