Bulacan Integrated Wood Industries Corp. (Biwico) v. Union Bank of the Philippines

Summary

BIWICO sued Union Bank for damages after the bank dishonored its checks due to signature verification concerns. The RTC initially awarded damages to BIWICO, but the CA reversed this decision. The Supreme Court affirmed the CA, ruling that Union Bank properly exercised its fiduciary duty by refusing to honor checks when signatures substantially differed from their records. The bank's extensive verification efforts, including multiple visits to BIWICO's office, demonstrated good faith. Since no breach of duty or bad faith was established, BIWICO's claim for damages was denied. The case emphasizes banks' responsibility to know their clients and verify signatures as part of their fiduciary obligations.
