Bliss Development Corp./Home Guaranty Corporation v. Montano Diaz

Summary

This case involved a property rights dispute where Montano Diaz acquired transfer rights to purchase property from Bliss Development Corporation through a series of assignments, ultimately paying P600,000.00 to Domingo Tapay and P406,915.15 in amortizations to BDC, plus P700,000.00 in improvements. When Edgar Arreza successfully challenged the validity of the original transfer (proving forged signatures), Diaz sued for reimbursement. The Supreme Court ruled that while Diaz was not a good faith purchaser due to his failure to diligently trace the source of purchase rights, BDC acted in bad faith by accepting payments while knowing of conflicting claims. Under the unjust enrichment doctrine and Civil Code Article 453 (treating both bad faith parties as good faith), the Court ordered BDC to reimburse Diaz P1,106,915.58 for payments and improvements, and Tapay to return P600,000.00, but deleted damage awards since both parties acted in bad faith.
