The contribution levied for each cancellation of registration is liquidated at the single rate of 0.10% on the sums subject to cancellation.
In the event of a reduction of the pledge, it is liquidated on the total amount of the sums secured by the registration or on the value of the property released if this value is declared in the deed and is less than the amount of the sums secured. In the event of a partial release having as its object the division of the mortgage, so that each immovable or fraction of an immovable now secures only part of the claim, the contribution relating to each of the partial discharges resulting from the division may not be liquidated on a sum greater than the fraction of the original claim of which each immovable or fraction of an immovable remains encumbered.
As an exception to the foregoing provisions, the contribution levied for the write-off required in accordance with the third paragraph of Article 2436 of the Civil Code shall be liquidated at a single rate of 0.05% on the sums subject to the write-off.
