"Tender of payment “is the manifestation by the debtor of a desire to comply with or pay an obligation. If refused without just cause, the tender of payment will discharge the debtor of the obligation to pay but only after a valid consignation of the sum due shall have been made with the proper court.”32 “Consignation is the deposit of the [proper amount with a judicial authority] in accordance with rules prescribed by law, after the tender of payment has been refused or because of circumstances which render direct payment to the creditor impossible or inadvisable.”33 “Tender of payment, without more, produces no effect.”34 “[T]o have the effect of payment and the consequent extinguishment of the obligation to pay, the law requires the companion acts of tender of payment and consignation.”35
As to the effect of tender of payment on interest, noted civilist Arturo M. Tolentino explained as follows:
When a tender of payment is made in such a form that the creditor could have immediately realized payment if he had accepted the tender, followed by a prompt attempt of the debtor to deposit the means of payment in court by way of consignation, the accrual of interest on the obligation will be suspended from the date of such tender. But when the tender of payment is not accompanied by the means of payment, and the debtor did not take any immediate step to make a consignation, then interest is not suspended from the time of such tender. x x x x. 36 (Emphasis supplied)
Here, the subject letter merely states Lourdes’ willingness and readiness to pay but it was not accompanied by payment. She claimed that she made numerous telephone calls to Atty. Carbon reminding the latter to collect her payment, but, neither said lawyer nor Constancia came to collect the payment. After that, the spouses Bonrostro took no further steps to effect payment. They did not resort to consignation of the payment with the proper court despite knowledge that under the contract, non-payment of the installments on the agreed date would make them liable for interest thereon. The spouses Bonrostro erroneously assumed that their notice to pay would excuse them from paying interest. Their claimed tender of payment did not produce any effect whatsoever because it was not accompanied by actual payment or followed by consignation. Hence, it did not suspend the running of interest. The spouses Bonrostro are therefore liable for interest on the subject installments from the date of default until full payment of the sums of P300,000.00 and P330,000.00.
