Article 38 — Subrogation
1. Subject to paragraph 2, nothing in this Convention affects the acquisition of associated rights and the related international interest by legal or contractual subrogation under the applicable law.
2. The priority between any interest within the preceding paragraph and a competing interest may be varied by agreement in writing between the holders of the respective interests but an assignee of a subordinated interest is not bound by an agreement to subordinate that interest unless at the time of the assignment a subordination had been registered relating to that agreement.
