Article 2073

When there are two or more guarantors of the same debtor and for the same debt, the one among them who has paid may demand of each of the others the share which is proportionally owing from him.

If any of the guarantors should be insolvent, his share shall be borne by the others, including the payer, in the same proportion.

The provisions of this article shall not be applicable, unless the payment has been made by virtue of a judicial demand or unless the principal debtor is insolvent. (1844a)
