2019 Mercantile Law, Q18

Mrs. T maintained a checking account with Bank U. While Mrs. T was abroad, she left her checkbook inside her office drawer, which she kept under lock and key. However, Mrs. T’s long-time secretary, Ms. S, knew where the checkbook was hidden. Ms. S then broke the lock on the office drawer, took one of Mrs. T’s blank checks, and succeeded to encash ₱200,000.00 from Bank U by imitating Mrs. T’s signature. As soon as Mrs. T returned from abroad and discovered the incident, she immediately reported the matter to Bank U, seeking that the transaction be reversed. However, the bank refused, contending that Mrs. T should bear the loss arising from the forgery.

1. Forged Signature Effects
Under Section 23 of the Negotiable Instruments Law (Act Number 2031), when a signature on a negotiable instrument is forged or made without the authority of the person whose signature it purports to be, it is wholly inoperative. No right to retain the instrument, or to give a discharge therefor, or to enforce payment thereof against any party thereto, can be acquired through or under such signature, unless the party against whom it is sought to enforce such right is precluded from setting up the forgery or want of authority.

2. Material Alteration Distinction
Under Section 125 of Act Number 2031, a material alteration is one that changes the date, sum payable, time or place of payment, number or relations of the parties, or currency specified, or adds a place of payment where none was specified. Fraudulently imitating or forging the drawer's signature on a blank check does not alter any existing contractual term of the instrument. Instead, forgery renders the signature wholly void under Section 23 rather than constituting a material alteration of an otherwise valid instrument under Section 125.

3. Drawee Bank Duty
A drawee bank is bound to know the specimen signatures of its depositors. When a bank pays a check bearing a forged drawer's signature, it pays out of its own funds and cannot charge the amount to the depositor's account. The depositor is not liable for the loss unless guilty of negligence that directly facilitated the forgery. Safekeeping a checkbook inside a locked office drawer demonstrates reasonable diligence, so the depositor cannot be deemed negligent or precluded from setting up the defense of forgery against the drawee bank.
