If the usufructuary shares with the owner the insurance of the tenement given in usufruct, the former shall, in case of loss, continue in the enjoyment of the new building, should one be constructed, or shall receive the interest on the insurance indemnity if the owner does not wish to rebuild.
Should the usufructuary have refused to contribute to the insurance, the owner insuring the tenement alone, the latter shall receive the full amount of the insurance indemnity in case of loss, saving always the right granted to the usufructuary in the preceding article. (518a)
