Odiamar vs. Valencia

Novation by substitution of debtor requires the express release of the original debtor from the obligation; mere assumption of debt by a third person without such release results only in the addition of debtors, not novation. Furthermore, monetary interest on a simple loan (mutuum) is not recoverable absent an express written stipulation between the parties.

The case involves a dispute over a P2,100,000.00 debt evidenced by a dishonored check. Respondent claimed the entire amount was personally owed by petitioner, while petitioner contended that P700,000.00 thereof constituted her deceased parents' obligation. The controversy required the Court to distinguish between a true novation by substitution of debtor (which would extinguish the parents' liability) and mere debt assumption (which results in cumulative liability), and to determine the applicability of interest charges on the principal obligation under the Civil Code provisions governing simple loans or mutuum.

• On August 20, 2003, respondent Linda Odiamar Valencia filed a complaint for sum of money and damages against petitioner Nympha S. Odiamar, alleging that the latter owed her P2,100,000.00 evidenced by China Bank Check No. GHB1147212 dated March 3, 2003, which was dishonored upon presentment.
• Respondent claimed that petitioner personally borrowed almost half of the P2,100,000.00 from her, with the remainder representing loans obtained by petitioner's deceased parents.
• Petitioner admitted during trial that she obtained personal loans from respondent separate from her father's borrowings, but contended that the P2,100,000.00 primarily represented her deceased parents' debt of P700,000.00, for which she was merely paying as administratrix of their estates.
• Petitioner issued the check to guarantee payment of the combined debt and made installment payments from December 29, 2000 to May 31, 2003 totaling P389,951.00, as evidenced by receipts whose genuineness were not disputed.
• Respondent admitted in her testimony that petitioner's deceased parents owed her approximately P700,000.00, while petitioner herself owed approximately P1,400,000.00, bringing the total principal to P2,100,000.00.
• There was no written agreement stipulating that the loans would bear interest, though respondent claimed there was an implicit understanding that the loans were interest-bearing because she herself borrowed the money from banks.
• The lower courts erroneously concluded that P2,000,000.00 was the principal and P100,000.00 represented accrued interest, and that novation by substitution of debtor had occurred releasing the parents' estates from liability.

• The debt was incurred by her deceased parents, not by her personally, and therefore respondent's claim should be filed in the proceedings for the settlement of her parents' estates.
• As administratrix of her parents' estates, she merely agreed to pay their indebtedness on installment basis, but this did not make her personally liable for the entire amount.
• The check was issued blank and respondent filled in the amount and date without authority.
• No novation occurred because there was no express agreement to release her parents' estates from their obligation.
• No interest was due on the loans because there was no express written stipulation therefor.
• She had made substantial installment payments which respondent accepted, and respondent later refused to accept further installment payments, demanding immediate full payment instead.

• Petitioner personally borrowed almost half of the P2,100,000.00 from her, as evidenced by the check which petitioner issued after agreeing to settle the debt in installments.
• The certification stating that petitioner's deceased parents were indebted was prepared by petitioner and signed by respondent only because she believed petitioner would make good her promise to pay.
• The P100,000.00 portion of the P2,100,000.00 represented accrued interest because petitioner undertook to pay the loan in installments.
• Novation occurred when petitioner assumed her parents' debt and began making installment payments, substituting herself as the new debtor.
• The loans were interest-bearing at three percent (3%) per month or thirty-six percent (36%) per annum, representing the interest respondent herself paid to banks from which she sourced the funds.

• Procedural Issues:
  • N/A
• Substantive Issues:
  • Whether novation by substitution of debtor occurred, thereby releasing the estates of petitioner's deceased parents from their P700,000.00 obligation and rendering petitioner solely liable for the entire P2,100,000.00 debt
  • Whether petitioner is liable for monetary interest on the principal debt in the absence of a written stipulation
  • Whether petitioner is liable for the full P2,100,000.00 or only for her personal borrowings of P1,400,000.00

• Procedural:
  • N/A
• Substantive:
  • The Court held that no novation by substitution of debtor took place because there was no allegation or proof that the estates of petitioner's deceased parents were expressly released from their P700,000.00 obligation. Under established jurisprudence, the fact that a creditor accepts payments from a third person who has assumed the obligation results merely in the addition of debtors, not novation.
  • The Court ruled that petitioner is liable only for her personal debt of P1,400,000.00, less the P389,951.00 already paid in installments, leaving a balance of P1,010,049.00. The remaining P700,000.00 remains the obligation of the parents' estates and must be claimed in the appropriate settlement proceedings.
  • The Court held that no monetary interest was due because Article 1956 of the Civil Code requires an express written stipulation for interest to be chargeable on a simple loan (mutuum). Respondent's admission that no such written agreement existed bars her from recovering interest.

• Novation by Substitution of Debtor — To constitute novation by substitution of debtor, the former debtor must be expressly released from the obligation and the third person or new debtor must assume the former's place in the contractual relations. The creditor's acceptance of payments from a third person who has assumed the obligation results merely in the addition of debtors, not novation. This doctrine distinguishes true novation from mere debt assumption or cumulative liability.
• Animus Novandi — The intent to novate, whether totally or partially, must appear by express agreement of the parties or by acts that are too clear and unequivocal to be mistaken. Novation is never presumed and the burden of proving the intent to novate rests on the party alleging it.
• Judicial Admissions — Admissions made by parties in their pleadings or in the course of trial or other proceedings in the same case are conclusive and do not require further evidence to prove them. They are legally binding on the party making them except when shown to have been made through palpable mistake.
• Simple Loan (Mutuum) and Interest Requirements — Under Article 1956 of the Civil Code, no interest shall be due unless it has been expressly stipulated in writing. This applies specifically to contracts of mutuum (simple loan) where fungible things like money are lent, and the borrower is obliged to return the same amount and kind. The lack of a written stipulation absolutely bars the creditor from charging monetary interest.

• "To constitute novation by substitution of debtor, the former debtor must be expressly released from the obligation and the third person or new debtor must assume the former's place in the contractual relations."
• "The fact that the creditor accepts payments from a third person, who has assumed the obligation, will result merely in the addition of debtors and not novation."
• "Novation is never presumed, and the animus novandi, whether totally or partially, must appear by express agreement of the parties, or by their acts that are too clear and unequivocal to be mistaken."
• "No interest shall be due unless it has been expressly stipulated in writing."
