Art.  2049.  A  married  woman  may  guarantee  an  obligation without  the  husband’s  consent,  but  shall  not  thereby  bind the conjugal partnership, except in cases provided by law. (n)
 
Art.   2050.   If   a   guaranty   is   entered   into   without   the knowledge  or  consent,  or  against  the  will  of  the  principal debtor, the provisions of Articles 1236 and 1237 shall apply. (n)

 

GUARANTY    UNDERTAKEN    WITHOUT    KNOWLEDGE    OF DEBTOR

     Always  remember  that  a  guaranty  is  unilateral.    It  exists for the benefit of the creditor and not for the benefit of the debtor.
     The  creditor  obviously  has every right to take all possible means to secure the payment of his credit
 

WHAT THEN IS THE RIGHT OF A THIRD PERSON WHO PAYS?

     Remember the rules on payment.

     A  person  who  pays  without  the  knowledge  or  against  the will of the debtor can recover only insofar as the payment has been  beneficial to the  debtor AND  he  cannot demand the creditor to subrogate him into his rights

     If  he  becomes  the  guarantor  with  the  knowledge  and consent  of  the  debtor,  he  is  subrogated  by  virtue  thereof to all the rights which the creditor has against the debtor
