Article 10

1. A vessel may be attached only by authorization of the judicial authority of the country in which the attachment is to take place. Such authorization which, if the law of the said country so provides may take the form of a validation, shall be granted if there is a danger that, unless immediate measures are taken, it may become uncertain whether the applicant can protect the enforcement of his claim or make it much more difficult for him to do so.

2. The provisions of paragraph 1 of this article shall apply even if the applicant's claim is a right in rem or a personal claim secured by such a right.
