Batas Pambansa Blg. 22 (BP 22), otherwise known as the Bouncing Checks Law, was enacted on 29 April 1979 to deter the issuance of worthless checks in commercial transactions and to safeguard the integrity of checks as a medium of payment. The law declares it a crime to make, draw, or issue a check without sufficient funds or credit with the drawee bank when the check is subsequently dishonored. Central to the prosecution of a BP 22 violation is the requirement of a valid notice of dishonor. Without it, the statutory presumption of the drawer’s knowledge of the insufficiency of funds does not arise, often leading to acquittal even when the check has in fact bounced.

Statutory Basis

The legal foundation is found in Section 2 of BP 22, which provides:

“The making, drawing and issuance of a check payment of which is refused by the drawee because of insufficient funds in or credit with such bank, when presented within ninety (90) days from the date of the check, shall be prima facie evidence of knowledge of such insufficiency of funds or credit unless such maker, drawer or issuer pays the holder thereof the amount due thereon, or makes arrangements for payment in full by the drawee of such check within five (5) banking days after receiving notice that such check has not been paid by the drawee.”

Two conditions must concur for the prima facie presumption to operate: (1) the check must have been presented for payment to the drawee bank within ninety (90) days from its date, and (2) the drawer must have failed to pay or make arrangements for payment within five (5) banking days after receiving notice of dishonor. The notice of dishonor is therefore the pivotal trigger that starts the running of the five-day period.

Purpose of the Notice of Dishonor

The notice serves a dual function. First, it informs the drawer of the fact of dishonor so that he may seasonably remedy the situation. Second, it creates the rebuttable presumption of knowledge of insufficiency at the time of issuance. Because BP 22 is a special penal law and malum prohibitum, the element of intent is replaced by this presumption once the notice requirement is satisfied. Absent proof of actual receipt of a valid notice, the prosecution must independently prove knowledge—an evidentiary burden that is extremely difficult to discharge.

Essential Requirements for a Valid Notice of Dishonor

For the notice to be considered valid and to trigger the five-day period, the following cumulative requirements must be met:

The Notice Must Inform the Drawer of the Dishonor
The communication must clearly convey that the check has been dishonored by the drawee bank for insufficiency of funds or credit (or for the related reason of a closed account). It is not necessary that the notice quote the exact reason stated in the bank’s debit memo, but it must be unequivocal. A vague statement such as “your check was returned” is insufficient. The notice should identify the check by number, date, amount, and payee so there can be no doubt as to which instrument is involved.
The Notice Must Be in a Form That Allows Proof of Content and Receipt
While BP 22 does not explicitly require the notice to be written, Philippine jurisprudence has consistently held that the safest and practically indispensable method is a written demand letter. Oral notice, though theoretically acceptable, is almost impossible to prove with the degree of certainty required in criminal cases. Written notice may be in the form of a formal demand letter, a lawyer’s letter, or even the bank’s own notice of dishonor if it sufficiently identifies the check and is actually received by the drawer.
Correct Address
The notice must be sent to the address appearing on the face of the check or to the drawer’s last known address. Sending the notice to a wrong or outdated address renders the notice ineffective. The Supreme Court has repeatedly ruled that when the drawer fails to update his address on the check, he cannot later complain that he did not receive the notice sent to the address he himself supplied. Conversely, if the holder knows of a different current address and deliberately ignores it, the notice may be held defective.
Proper Mode of Service
Acceptable modes include:
- Personal service (with acknowledgment of receipt or an affidavit of service).
- Registered mail with return card.
- Private courier services, provided actual receipt is established by competent evidence.
  Registered mail accompanied by the registry receipt and the signed return card creates a presumption of receipt that is very difficult to overcome. Mere proof of mailing (registry receipt alone) without the return card is generally insufficient to prove actual receipt.
Proof of Actual Receipt
This is the single most critical requirement. The five-day period begins only upon receipt, not upon mailing. The prosecution bears the burden of proving receipt by clear and convincing evidence. The usual evidence consists of:
- The return card bearing the signature of the addressee or an authorized person and the date of receipt.
- Testimony of the person who personally served the notice.
- Admission by the drawer (in a pleading, during investigation, or in open court).
  If the return card is unsigned or the signature is not shown to belong to the drawer or his authorized representative, courts will not presume receipt. Refusal to accept the registered mail, when properly documented, is generally considered equivalent to receipt.
The Five Banking Days Period
Once valid notice is received, the drawer has exactly five (5) banking days within which to pay the amount of the check or make arrangements for its full payment. “Banking days” exclude Saturdays, Sundays, and legal holidays. The period is counted from the date of actual receipt. Partial payment or a post-dated check tendered after the period will not cure the violation. Payment or arrangement must be made directly with the holder or through the drawee bank in a manner that fully discharges the obligation.

Special Situations and Jurisprudential Nuances

Bank’s Notice of Dishonor
Many banks send their own debit memos or notices to the drawer. If such notice is actually received and contains the required information, it may suffice. However, the more common and safer practice is for the payee or his counsel to send a separate demand letter after receiving the bank’s debit memo.
Closed-Account Cases
When the check is dishonored because the account is already closed, the same notice requirement applies. The presumption still operates once the drawer receives notice and fails to pay within five banking days.
Corporate Drawers
When the check is issued by a corporation, notice must be served on the officer who signed the check or on the corporation at its principal address. Service on the corporation alone may not bind the individual signatory unless it is shown that the individual actually received the notice.
Multiple Checks
A single demand letter listing all dishonored checks is acceptable provided each check is properly identified and the drawer is given five banking days from receipt to cover all of them.
Timing of the Notice
There is no fixed deadline for sending the notice after dishonor, but it must be sent within a reasonable time. The ninety-day presentation period refers only to the check’s presentment to the bank, not to the sending of notice. Nevertheless, unreasonable delay may raise doubts about good faith or may prejudice the drawer’s ability to verify the status of his account.
Absence of Notice but Actual Knowledge
Although the statutory presumption requires notice, the prosecution may still prove the element of knowledge by other competent evidence (e.g., the drawer’s own admission, prior warnings from the bank, or testimony that he knew his account balance was insufficient). In practice, however, courts rarely convict without the presumption, making a valid notice practically indispensable.

Effect of Defective or Non-Existing Notice

If the notice is defective in any of the foregoing respects, the presumption of knowledge does not arise. The prosecution must then prove actual knowledge at the time of issuance—an almost insurmountable burden in most cases. Consequently, the accused is entitled to acquittal. This strict requirement underscores the due-process character of the notice: the drawer must be given a fair opportunity to avoid criminal liability by making good the check within the grace period.

Practical Guidelines for Holders and Practitioners

To ensure the validity of the notice:

Immediately upon receipt of the bank’s debit memo, prepare a formal demand letter identifying the check and demanding payment within five banking days.
Send the letter by registered mail with return card to the exact address on the check.
Retain the registry receipt and, when the return card comes back, attach it to the complaint-affidavit.
If personal service is chosen, prepare an affidavit of service and have it subscribed before a notary.
Keep a photocopy of the entire demand letter and proof of mailing/receipt for presentation in court.

The notice of dishonor is not a mere formality; it is the cornerstone upon which the entire edifice of BP 22 liability rests. A meticulously prepared and properly served notice, coupled with irrefutable proof of receipt, almost invariably leads to conviction once the other elements are established. Conversely, the slightest defect in form, service, or proof of receipt is often fatal to the prosecution’s case. In the Philippine legal landscape, mastery of the requirements for a valid notice of dishonor remains the single most decisive factor in the successful prosecution or defense of a bouncing-checks case.
