Article 31 — Adaptation of rights in rem

Where a person invokes a right in rem to which he is entitled under the law applicable to the succession and the law of the Member State in which the right is invoked does not know the right in rem in question, that right shall, if necessary and to the extent possible, be adapted to the closest equivalent right in rem under the law of that State, taking into account the aims and the interests pursued by the specific right in rem and the effects attached to it.
