Cap. 16 Art. 2027Sum for which hypothec is contracted to be specified in the deed.

A conventional hypothec is not valid if the sum for which it is agreed upon is not specified and stated in the deed. If the debt resulting from an obligation is conditional as to its existence, or indeterminate as to its value, the creditor cannot demand the registration of the hypothec except for an amount expressly stated by him, saving the right of the debtor to cause such amount to be reduced, where competent.
