In the Philippine legal system, notarization transforms a private document into a public document. This transition carries significant weight, as a public document is admissible in evidence without further proof of its authenticity and serves as prima facie evidence of the facts stated therein. Central to this legal transformation is the date of notarization.

A frequent point of confusion arises regarding the sequencing of dates: Can a notarized document be dated after the date of its notarization? Under the 2004 Rules on Notarial Practice (A.M. No. 02-8-13-SC) and established jurisprudence, the answer is a resounding no.

1. The Nature of the Notarial Act

To understand why the dates cannot be mismatched in this manner, one must look at what a notary public actually certifies. Whether through an Acknowledgment or a Jurat, the notary is attesting to a specific event occurring in their presence on a specific day.

Acknowledgment: The notary certifies that the person appearing before them is the same person who executed the instrument and acknowledged that the same is their free and voluntary act and deed.
Jurat: The notary certifies that the instrument was signed and sworn to (or affirmed) before them by the signatory.

In both instances, the notary public must indicate the date and place of the notarial act. If a document is notarized on May 1st, but the body of the document is dated May 15th, it creates a legal paradox: the notary is essentially certifying the execution of a document that, according to its own terms, does not yet exist.

2. Legal Implications of Post-Dating the Document

In the Philippine context, dating a document after its notarization is considered a violation of the integrity of public records.

A. Violation of the 2004 Rules on Notarial Practice

The Rules require a notary to record every notarial act in their Notarial Register chronologically. The entry must include the date of the act. If the document date is later than the notarization date, it suggests that the notary signed a blank or incomplete document, or that the parties did not actually appear on the date stated. Both scenarios are grounds for the revocation of a notarial commission and perpetual disqualification from being a notary public.

B. Falsification of Public Documents

Under the Revised Penal Code (RPC), specifically Article 171 (Falsification by public officer, employee or notary), making untruthful statements in a narration of facts is a criminal offense. A notary who certifies that a document was acknowledged on a certain date, when the document itself bears a future date, is arguably making a false narration regarding the timeline of the document's execution.

C. Loss of Evidentiary Value

The primary benefit of notarization is the legal presumption of regularity. When a document exhibits a "future date" relative to its notarization, this presumption is destroyed. The document becomes highly susceptible to challenges in court, and its validity as a public instrument may be nullified, reverting it to the status of a private document that requires independent proof of authenticity.

3. The "Backdating" vs. "Post-dating" Distinction

While this article focuses on dating a document after notarization, it is important to distinguish this from common (though still illegal) practices:

Backdating: Notarizing a document today but putting a past date on the notarial seal. This is strictly prohibited and constitutes a direct fraud on the court and the public.
Post-dating the Document: The scenario at hand. Even if the notary uses the "correct" current date for the notarization, if the document's effective date or execution date is in the future, the notary is witnessing a "non-entity."

Rule of Thumb: The date of execution (the date written in the document) should ideally be the same as, or prior to, the date of notarization. It can never be later.

4. Consequences for the Parties and the Notary

The Supreme Court of the Philippines has historically been unforgiving toward irregularities in dates.

For the Notary: The notary faces administrative sanctions, including suspension or disbarment. The Court emphasizes that notarization is not an empty, meaningless, or routine act; it is invested with substantive public interest.
For the Parties: The document may be declared void or unenforceable, especially in contracts where the date of execution is material (e.g., Deeds of Sale, Wills, or Powers of Attorney).
For the Document: It loses its "self-authenticating" status. In litigation, the party relying on the document would have to call witnesses to prove the document was actually signed, incurring more costs and legal risks.

Conclusion

In Philippine Law, the chronological integrity of a document is sacred. A document cannot be dated after the date of its notarization. To allow such a practice would undermine the very purpose of the Notarial Law, which is to ensure the authenticity and reliability of written instruments. Parties must ensure that the document is fully accomplished and correctly dated on or before the moment they stand before the notary public.
