1021. That which is due with a term of payment cannot be exacted before the expiration of the term; but that which has been paid in advance voluntarily and without error or fraud cannot be recovered.
1022. The term is presumed to be stipulated in favour of the debtor, unless, from the stipulation or the circumstances, it appears that it has been agreed upon in favour of the creditor also.
1023. The debtor cannot claim the benefit of the term when he or she has become bankrupt or insolvent, or has by his or her own act diminished the security given to his or her creditor by the contract.
