EFFECT  OF  PAYMENT  BY  GUARANTOR  BEFORE  OR  AFTER MATURITY

Art.  2069.  If the debt was for a period and the guarantor paid it before it became due, he cannot demand reimbursement of the debtor until the expiration  of  the period unless the payment has been ratified by the debtor. (1841a)

1.   If principal  obligation is  with a period,  it  becomes demandable  only  when the day fixed comes. The guarantor cannot demand reimbursement if he pays before maturity since there is no necessity to accelerate payment.

2.   It would be different though if the debtor consented to the payment  or  subsequently  ratifies  it. The  guarantor  may not demand reimbursement from the debtor.

3.   What  is  controlling  is  that  the  default  or  demand  on guarantor  had taken  place  while  the  guarantee is still  in force—when the payment was made during the term of the guarantee.
