Works over which the holder has rights in rem or of which it is the owner may only be mortgaged with a view to guaranteeing loans taken out to finance the performance of its obligations under the partnership contract.
The contract constituting the mortgage must, on pain of nullity, be approved by the purchaser and, where applicable, by the person owning the estate.
Only mortgage creditors may exercise precautionary measures or enforcement measures over the property rights resulting from the contract.
