An Affidavit of Explanation for an Undeclared Passport is a sworn written statement used in the Philippines to explain why a passport was not previously disclosed, declared, surrendered, presented, or reported when it should have been, depending on the transaction involved. It is not a single affidavit form defined by one universal statute. Rather, it is a supporting sworn document commonly required by a government office, court, embassy, school, employer, licensing body, or private institution when there is a discrepancy involving a passport.

In Philippine practice, this affidavit is usually requested when a person must explain facts such as:

a passport existed but was not disclosed in an earlier application or record
an old passport was not declared when applying for a new one
a second or previously issued passport was omitted from travel, immigration, civil, employment, or administrative records
a passport was misplaced, forgotten, damaged, or retained elsewhere and therefore not presented when required
a passport number, date of issue, or travel history was omitted or inconsistently stated
a passport was not declared in relation to a legal, administrative, or documentary compliance issue

The affidavit serves one main function: to place the explanation under oath so the receiving authority can assess the omission, reconcile the records, and determine whether the omission was an honest mistake, negligence, or a matter with possible legal consequences.

1. What “undeclared passport” usually means

In Philippine usage, an “undeclared passport” usually refers to a passport that was not mentioned or reported when a person was expected to mention or report it. The exact meaning depends on the context.

A. In passport renewal or replacement

A person may have failed to disclose an old passport, a previously issued passport, or a damaged/lost passport when dealing with the Department of Foreign Affairs.

B. In immigration or travel records

A traveler may have omitted a passport from records, especially where there were multiple travel documents, an old passport, or a passport renewed after earlier travel.

C. In civil or personal records

A passport may have been omitted when establishing identity, citizenship, marital status, names used, or foreign travel history.

D. In employment, licensing, or administrative matters

A person may have been required to declare all government IDs, travel documents, aliases, dual nationality documents, or international travel records, but did not include the passport.

E. In court or quasi-judicial proceedings

A passport may not have been disclosed in pleadings, compliance submissions, probate records, family law matters, labor cases, or other proceedings where identity or travel is relevant.

The phrase does not automatically mean fraud. It only means there was a failure to declare. Whether that failure is innocent or serious depends on the facts.

2. Why an affidavit is required

An affidavit is required because the receiving office usually wants a formal, sworn explanation rather than an informal letter. In Philippine legal practice, sworn statements carry greater evidentiary and procedural weight than unsigned explanations.

The affidavit is used to:

explain the omission clearly and chronologically
identify the passport and its status
correct or supplement official records
show good faith
reduce suspicion of concealment
support a request for acceptance of late disclosure, correction, or reconsideration
create a written basis for administrative action

It is especially important where the authority has flagged a mismatch in records, such as inconsistent names, undeclared prior travel, or non-disclosure of an older passport.

3. Nature of the document under Philippine law

An affidavit in the Philippines is a sworn written declaration subscribed and sworn to before a notary public or other authorized officer. The person signing it is the affiant.

Because it is sworn, false statements may expose the affiant to legal consequences, including possible liability for:

perjury, if the statement contains deliberate falsehoods on material facts
falsification, if documents or entries are fabricated or materially altered
administrative sanctions, if submitted in a regulated process
denial, suspension, or delay of the underlying application or request

So the affidavit must be truthful, precise, and limited to facts personally known by the affiant, except where clearly stated as based on records.

4. When this affidavit is commonly used in the Philippines

There is no single exclusive list, but common situations include the following.

A. DFA-related matters

An affidavit may be requested when a person:

did not disclose a previously issued passport
failed to present or declare an old passport during renewal
needs to explain why a passport was lost, not surrendered, or not mentioned
has discrepancies between old and new passport data
used a different name in an earlier passport and must explain the inconsistency

B. Immigration-related matters

It may be used to explain:

omission of passport details in prior applications or declarations
undeclared prior passport linked to travel records
non-disclosure of an expired passport
inconsistencies between arrival/departure history and documents submitted

C. Embassy or visa matters

Applicants sometimes need it to explain:

failure to declare a prior passport in visa forms
old passports not listed in travel history
omission of a cancelled or expired passport
differing passport numbers across applications

D. Civil registry or identity correction matters

The affidavit may explain:

identity inconsistencies involving passport records
omission of passport details in name or citizenship-related documentation
mismatch between passport name and civil registry entries

E. School, employment, regulatory, and private documentation

An institution may require it where a person:

failed to disclose foreign travel or an existing passport
omitted a passport from compliance forms
needs to reconcile old identity records with current records

F. Court and legal proceedings

It may be attached to motions, petitions, or compliance submissions where a passport was not earlier disclosed but later became relevant.

5. What the affidavit should accomplish

A proper affidavit of explanation should do more than say, “I forgot.” It should answer the real concerns of the receiving authority:

What passport was omitted?
When and where was it issued?
Why was it not declared?
Was the omission intentional or inadvertent?
What is the current status of the passport?
Are there supporting documents?
What correction or action is now being requested?

If those points are not clearly addressed, the affidavit may be viewed as incomplete.

6. Essential contents of the affidavit

A Philippine affidavit of this kind usually contains the following parts.

A. Title

Typical title:

AFFIDAVIT OF EXPLANATION or AFFIDAVIT OF EXPLANATION FOR UNDECLARED PASSPORT

The title can be tailored to the office’s requirement.

B. Identification of the affiant

The affiant should state:

full legal name
age
citizenship
civil status, where relevant
present address

Example style:

I, Juan Dela Cruz, of legal age, Filipino, single, and residing at [address], after having been duly sworn in accordance with law, do hereby depose and state:

C. Statement of competence and personal knowledge

The affiant should make clear that the facts are based on personal knowledge and authentic records.

D. Description of the passport

Identify the passport as completely as possible:

passport number
date of issue
place of issue
date of expiry
name appearing on the passport
whether it is valid, expired, cancelled, lost, damaged, withheld, or unavailable

If exact data is unavailable, say so honestly and explain why.

E. Explanation of the omission

This is the heart of the affidavit. It should state:

when the declaration should have been made
in what form, application, proceeding, or transaction
why the passport was not declared
whether the omission resulted from mistake, oversight, loss of records, confusion, name discrepancy, misunderstanding, or similar cause
that there was no intent to mislead, if true

F. Clarification of relevant surrounding facts

Depending on the case, explain:

whether there were multiple passports over time
whether an old passport was already expired
whether it was forgotten because it had long been unused
whether it was physically unavailable
whether the passport was under a former name
whether a travel agency, employer, relative, or third party held the document
whether the omission arose from a misunderstanding of the question asked in the form

G. Current corrective step

State what the affiant is now doing:

declaring the passport
submitting a copy
requesting acceptance of the explanation
asking for correction of records
asking the office to proceed despite the earlier omission

H. Good-faith statement

It is common to include that the omission was not intended to conceal material facts, commit fraud, or mislead the authority.

I. Purpose clause

The affidavit should state why it is being executed, for example:

I am executing this Affidavit to explain the non-declaration of my passport and for whatever legal and administrative purpose it may serve.

J. Signature and jurat

The affiant signs before the notary public. The notary completes the jurat, stating that the affiant personally appeared and swore to the truth of the affidavit.

7. Supporting documents commonly attached

An affidavit is stronger when supported by documents. Common attachments include:

photocopy of the undeclared passport’s bio page
photocopy of old and new passports
passport renewal acknowledgment or DFA records, if available
police report, if loss is also involved
affidavit of loss, if applicable
birth certificate, marriage certificate, or court order showing name changes
government IDs
travel records, boarding passes, or visas, if relevant
correspondence from the office requiring the explanation
application form where the omission occurred
certification from employer, school, or agency, if relevant

An affidavit should not attach irrelevant documents. Every attachment should support a fact asserted in the statement.

8. Drafting standards: what makes it legally sound

A good affidavit in Philippine practice has these qualities:

A. It is factual, not emotional

The affidavit should state facts, dates, and circumstances. It should not argue excessively or attack the receiving office.

B. It is specific

Vague language such as “I forgot some details” is weak. Better is:

what was omitted
when the omission occurred
why it happened
what is being done now

C. It is chronological

A sequence of events helps the reviewing officer understand the situation.

D. It is truthful and limited to what can be sworn to

Do not speculate. If uncertain, say “to the best of my recollection” only where appropriate, and do not use that phrase to hide weak facts.

E. It matches the records

Names, dates, passport numbers, and places must align with attachments and official documents.

F. It avoids self-inflicted admissions beyond necessity

Explain the omission honestly, but do not include unnecessary statements that create avoidable legal exposure.

G. It is notarized properly

An unsigned or unnotarized affidavit may be rejected if a sworn statement is specifically required.

9. Difference from related affidavits

This affidavit is often confused with other sworn documents. They are not the same.

A. Affidavit of Loss

Used when the passport is lost. If the problem is both loss and non-declaration, both issues may need to be addressed, sometimes in separate affidavits, depending on the office’s requirements.

B. Affidavit of Discrepancy

Used when there is a discrepancy in names, dates, or other entries. If the undeclared passport issue is tied to a name mismatch, both explanation and discrepancy may need to be covered.

C. Affidavit of One and the Same Person

Used when different names refer to the same person. This may be needed if the undeclared passport was under a different surname or spelling.

D. Letter of Explanation

This is less formal and not under oath. Some offices accept a letter; others insist on an affidavit.

E. Judicial or administrative verified pleading

A verified pleading is different from a stand-alone affidavit, though both are sworn.

10. Whether there is a specific law on “undeclared passport”

There is generally no single Philippine law titled specifically for an “undeclared passport affidavit.” The need for such an affidavit usually arises from the broader legal and administrative framework governing:

passports and travel documents
truthful declarations in government forms
notarial practice
evidentiary use of affidavits
administrative compliance and identity verification

This is why wording varies from one institution to another. The core issue is not the title of the affidavit, but whether the statement adequately explains the omission and helps the authority decide what to do.

11. Legal significance of non-declaration

Not every non-declaration is treated equally.

A. Innocent omission

This may happen due to:

oversight
genuine forgetfulness
misunderstanding of the form
failure to locate an old passport
name changes creating confusion
clerical or documentary disorganization

Usually, a clear affidavit plus supporting documents may be enough.

B. Negligent omission

This involves carelessness, such as submitting incomplete information despite an opportunity to verify. The authority may still accept correction, but the omission may cause delay or added scrutiny.

C. Potentially intentional concealment

This is more serious. Examples include deliberate hiding of a passport to obscure travel history, identity, or prior applications. In that situation, an affidavit alone may not cure the issue. The office may refer the matter for investigation or deny the request.

The difference often turns on the facts, timing, consistency, and documentary support.

12. Common reasons given in these affidavits

Commonly acceptable reasons, if true, include:

the passport had already expired and was inadvertently overlooked
the passport was kept among old documents and was forgotten
the affiant misunderstood the form as asking only for the current valid passport
the passport was under a former surname or different name format
the passport was not available at the time of filing
the affiant believed an old cancelled passport no longer needed to be declared
the omission was due to clerical or inadvertent error

Reasons that are risky unless very well explained include:

“I did not think it was important”
“I was told not to mention it”
“I wanted the process to be simpler”
“I feared it would raise questions”

Those can suggest awareness and concealment.

13. Issues involving name changes and multiple passports

In the Philippines, undeclared passport issues often overlap with identity changes, especially after marriage, annulment, correction of entries, recognition of foreign divorce, adoption, or dual citizenship matters.

Important points:

A. Same person, different name

If the undeclared passport bears an older name, the affidavit should explain:

old name used
reason for current name
documents supporting the change

B. Old passport vs current passport

If the undeclared document is an old expired passport, say that clearly. Authorities are usually concerned with the full documentary history, not only validity.

C. Dual nationality concerns

Where lawful dual nationality exists, the affidavit should be especially careful and fact-specific. It should not make incorrect statements on citizenship status or the legal effect of foreign documents.

14. Notarization in the Philippines

To be valid as a notarized affidavit, the affiant normally must:

appear personally before a notary public
present competent proof of identity
sign the document in the notary’s presence, if not already signed before the notary under proper procedure
swear that the contents are true

The notary will complete the jurat and record the act in the notarial register.

Practical points:

A photocopy alone is not the same as the notarized original.
Some offices want the original notarized affidavit.
Others accept a certified true copy or scanned copy, but requirements vary.
If executed abroad, consular or equivalent authentication rules may apply depending on use.

15. Evidentiary value of the affidavit

An affidavit is evidence, but its weight depends on credibility and consistency. In administrative settings, it may be sufficient if supported by records. In contested proceedings, a bare affidavit may carry less weight than live testimony and official documents.

An affidavit of explanation is strongest when:

it is detailed
it is internally consistent
it matches attachments
it was made promptly after the issue was discovered
there is no contradictory statement elsewhere

It is weak when:

it is generic
it omits key dates
it conflicts with submitted forms
it changes explanations over time
it appears tailored only after the discrepancy was discovered

16. Risks of a defective affidavit

A poorly prepared affidavit can create more problems than it solves. Common defects include:

wrong passport number
incomplete identification of the affiant
failure to state where the omission occurred
no explanation why it was omitted
contradictory dates
careless statements implying concealment
absence of attached proof
not notarized despite a notarial requirement
use of copied template language that does not fit the facts

Consequences may include:

rejection of the affidavit
request for a revised affidavit
delay in processing
referral for further verification
possible legal exposure if false statements are made

17. How detailed should the affidavit be?

It should be detailed enough to explain the omission fully, but not overloaded with unnecessary information.

Include:

identity
passport details
transaction where the omission happened
reason for non-declaration
corrective action
purpose of the affidavit

Usually unnecessary unless specifically relevant:

unrelated travel details
personal grievances
broad life history
legal conclusions the affiant is not qualified to make

The rule is simple: include facts needed to resolve the issue, nothing more.

18. Tone and wording

The best tone is:

respectful
candid
neutral
factual
concise but complete

Bad tone:

defensive
angry
evasive
overly dramatic
argumentative without need

Useful wording patterns include:

“through oversight”
“due to inadvertence”
“because I understood the requirement to refer only to my current valid passport”
“the passport was under my former name”
“I am now voluntarily declaring the same”
“there was no intention to mislead”

Only use such wording if it is true.

19. Sample structure

A common structure in Philippine legal drafting is:

Title
Introductory identification
Statement of oath
Facts about the passport
Facts about the omission
Explanation of why the omission occurred
Statement of good faith
Corrective disclosure
Purpose clause
Signature
Jurat

20. Sample affidavit template

Below is a general template. It should be adjusted to the actual facts.

AFFIDAVIT OF EXPLANATION FOR UNDECLARED PASSPORT

I, [Full Name], of legal age, [citizenship], [civil status], and residing at [complete address], after having been duly sworn in accordance with law, hereby depose and state:

That I am the same person who is executing this Affidavit based on my personal knowledge and on authentic records in my possession;
That I previously held/hold Philippine Passport No. [passport number], issued on [date] at [place], under the name [name appearing on passport], with expiry date of [date];
That during [state the application, transaction, proceeding, or submission], I failed to declare/disclose the said passport;
That the non-declaration of the said passport was due to [oversight/inadvertence/confusion regarding old passport status/name discrepancy/unavailability of records/other truthful reason];
That at the time of said submission, [state relevant surrounding facts, such as the passport being expired, under a former name, unavailable, misplaced among old records, or believed not to be required];
That I am now voluntarily declaring the existence/details of the said passport in order to clarify and correct the records;
That the non-declaration was not made with intent to mislead, conceal material information, or commit fraud, but was the result of an honest mistake/inadvertence;
That I am executing this Affidavit to explain the non-declaration of my passport and for whatever legal and administrative purpose it may serve.

IN WITNESS WHEREOF, I have hereunto set my hand this [date] at [city/province], Philippines.

[Signature over printed name] Affiant

SUBSCRIBED AND SWORN to before me this [date] at [place], affiant exhibiting to me [ID details] as competent evidence of identity.

[Notary Public]

21. Sample fact patterns and how they should be framed

A. Old expired passport not declared in renewal-related transaction

The affidavit should say the passport was expired, no longer in active use, and inadvertently overlooked, but is now being disclosed.

B. Passport under former married surname not declared

The affidavit should link the old passport to the current identity and attach the marriage certificate or relevant name-change document.

C. Passport omitted because it was unavailable at time of filing

State where it was, why it was unavailable, and that the omission is now being corrected upon retrieval or confirmation.

D. Multiple passports over time; one omitted by mistake

Set out the chronology clearly: first passport, later passport, current passport, which one was omitted, and why.

E. Passport details inconsistent with another record

Explain whether the issue concerns clerical difference, old vs current data, or change in civil status or name.

22. Whether an affidavit alone is enough

Not always. It depends on what the receiving office needs.

An affidavit may be enough where:

the issue is minor
the omission is plausibly inadvertent
the records are otherwise consistent
supporting documents are available

It may not be enough where:

there is suspected fraud
multiple inconsistencies exist
the omission affected legal rights or official decisions
the office needs independent certification, records verification, or a separate affidavit

In practice, the affidavit is often part of a bundle of corrective documents, not the only document.

23. Importance of consistency with prior statements

One of the biggest practical issues is consistency. Before signing the affidavit, compare it against:

earlier applications
IDs
prior affidavits
passport records
civil registry documents
visa applications
court papers
immigration declarations

The explanation must reconcile, not worsen, the discrepancy.

24. Use in administrative discretion

Many Philippine offices decide these matters through administrative review. A well-crafted affidavit helps the officer exercise discretion favorably by showing:

voluntary correction
candor
explanation supported by documents
absence of bad faith
willingness to comply

Timing matters. A prompt, spontaneous correction is better than an explanation made only after the office uncovers the issue.

25. Consequences of intentional falsehood

Because the affidavit is sworn, knowingly false material statements may lead to serious consequences. These may include:

rejection of the application or request
blacklisting or administrative scrutiny, depending on the office
possible criminal complaint where the facts warrant
damage to credibility in related proceedings

A common mistake is trying to make the story sound cleaner than it was. In affidavits, accuracy is safer than embellishment.

26. Practical drafting checklist

Before finalizing the affidavit, check the following:

correct full legal name
current address
correct passport number
issue and expiry dates
exact transaction where omission happened
clear reason for non-declaration
statement that the omission was unintentional, if true
corrective disclosure language
relevant attachments
proper notarization
no contradiction with existing records

27. Common mistakes to avoid

Avoid these drafting errors:

saying the passport did not exist when it actually did
omitting the passport number when it is available
using a generic explanation without facts
blaming another person without basis
making legal conclusions instead of factual statements
hiding name discrepancies
attaching documents that contradict the affidavit
signing without reading carefully
notarizing a document with inaccuracies

28. Suggested article-style conclusion on the subject

In the Philippine setting, an Affidavit of Explanation for an Undeclared Passport is best understood not as a rigid statutory form, but as a fact-specific sworn corrective instrument. Its role is to explain an omission, restore documentary consistency, and allow an authority to determine whether a passport that was not declared earlier can now be properly accounted for without prejudice to the relevant process.

Its legal value lies in four things: truth, specificity, consistency, and proper notarization. When the omission is genuinely inadvertent and the affidavit is supported by records, it can be an effective tool for curing documentary defects. When the omission was intentional or the explanation is false, the affidavit can instead become the very document that exposes the problem.

For that reason, the most important rule is simple: state the facts plainly, completely, and under oath only if they are true.
