Quick answer

Any person may file a complaint with the Office of the Ombudsman against a Philippine public officer or employee for an allegedly illegal, unjust, improper, inefficient, corrupt, or otherwise actionable act or omission connected with public office. A private person may also be included when the evidence shows participation or conspiracy with a public officer.

For the strongest filing, submit a verified complaint-affidavit that clearly identifies the respondents, tells the facts in chronological order, specifies the acts attributed to each respondent, and attaches the available evidence. Include a verified Certificate of Non-Forum Shopping.

The Ombudsman’s current filing checklist requires:

Copies of the verified complaint-affidavit equal to the number of named respondents, plus four additional copies, with at least two originally signed copies;
The same number of copies of supporting documents and other evidence, when applicable; and
At least two original copies of the verified Certificate of Non-Forum Shopping.

The Office may receive complaints in other written forms, but a complete, sworn, evidence-supported complaint is more likely to proceed without avoidable requests for clarification or supporting affidavits. Check the official filing page immediately before submission because documentary and receiving requirements can change.

What complaints belong with the Ombudsman?

The Ombudsman may investigate an act or omission of a government officer or employee when it appears illegal, unjust, improper, or inefficient. Its authority covers officials and employees of national agencies, local government units, government instrumentalities, and government-owned or controlled corporations within the coverage of the Constitution and the Ombudsman Act of 1989.

Depending on the facts, one filing may raise:

A criminal complaint, such as an alleged violation of the Anti-Graft and Corrupt Practices Act, the Code of Conduct and Ethical Standards for Public Officials and Employees, applicable provisions of the Revised Penal Code, or another offense committed in relation to public office;
An administrative complaint, involving misconduct, dishonesty, oppression, neglect of duty, conduct prejudicial to the service, or another disciplinary ground;
A possible forfeiture matter, involving allegedly unlawfully acquired or unexplained property; or
A grievance or request for assistance, when the immediate concern is delay, refusal to act, unfair treatment, red tape, or another government-service problem that may not yet amount to a criminal or administrative charge.

You do not have to force the facts into a particular offense if you are uncertain. Describe the conduct accurately and attach the records that support it. The Ombudsman evaluates and classifies what it receives. If you name a particular crime or administrative offense, however, make sure the factual allegations and evidence address its legal elements.

Matters the Ombudsman may decline or refer elsewhere

The Ombudsman is not the proper forum for every dispute involving someone who happens to work for the government.

A complaint may be dismissed, declined, or referred when, for example:

It concerns a purely private dispute with no sufficient connection to public office;
Another court, tribunal, or agency has exclusive jurisdiction;
It merely asks the Ombudsman to reverse or review a ruling that must be challenged through the appeal or review process provided by law;
It is trivial, frivolous, vexatious, made in bad faith, or unsupported by meaningful particulars;
An adequate remedy is available in another judicial or quasi-judicial body;
A criminal offense has clearly prescribed; or
An administrative complaint was filed more than one year after the act or omission.

The one-year provision for administrative complaints is not an absolute statute of limitations. Section 20 of the Ombudsman Act gives the Ombudsman discretion not to investigate a late administrative complaint. The Supreme Court has confirmed that “may” in this provision is permissive, not mandatory. Delay can nevertheless make dismissal more likely and can seriously weaken the evidence, so file promptly. See Office of the Ombudsman v. Court of Appeals.

Criminal prescription is different. The applicable period depends on the offense, the date and circumstances of its commission or discovery, and the law governing interruption of the period. Do not assume that the one-year administrative rule controls a criminal charge.

Special limits on administrative jurisdiction

The Ombudsman generally has disciplinary authority over elective and appointive government officials and employees, but not over:

Officials removable only by impeachment;
Members of Congress; and
Members of the Judiciary.

These limits do not always eliminate the Ombudsman’s investigatory authority. For example, it may investigate serious misconduct by an impeachable official for the purpose of filing a verified impeachment complaint if warranted. A criminal investigation may also present different jurisdictional questions from an administrative disciplinary case.

Complaints about judges and court personnel generally belong within the Supreme Court’s administrative supervision, commonly through the Office of the Court Administrator. Complaints concerning a legislator’s discipline belong to the appropriate chamber of Congress. Because the correct forum can turn on the respondent’s position and the relief sought, obtain legal advice where these exceptions may apply.

Step 1: Identify each respondent precisely

Give as much of the following information as you reasonably know:

Full name;
Government position and office;
Office or work address;
Email address or other contact information, if known; and
Status at the time of the alleged act, including whether the person has since resigned, retired, transferred, or left office.

Do not list an entire office as the only respondent if particular officers signed, approved, certified, received, released, or withheld the documents or funds in question. Explain the role of each named person. Avoid naming someone solely because that person was the head of the agency; administrative and criminal liability ordinarily require a factual basis connecting the individual to the alleged wrongdoing.

If a private individual or company participated with a public officer, identify that person or entity and describe the specific participation. Mere association with a public official is not enough.

Step 2: Prepare a clear statement of facts

Write a chronological, factual account. For each important event, state:

What happened;
When and where it happened;
Who took part;
What each person said, signed, approved, received, paid, delivered, or failed to do;
How you learned the fact; and
Which attachment supports it.

Separate personal knowledge from information obtained from records or other people. If you do not know an exact date, say that it is approximate. If a fact is an inference, identify the documents or circumstances supporting that inference.

A useful structure is:

The complainant’s identity and basis of knowledge;
The respondents’ positions and official functions;
A numbered chronology of the events;
The specific act or omission attributed to each respondent;
The resulting public loss, private injury, improper benefit, delay, or other consequence;
The supporting evidence and witnesses; and
The action requested from the Ombudsman.

Use neutral language. State what the evidence shows instead of relying on labels such as “corrupt,” “thief,” or “criminal.”

Step 3: Attach evidence that can be authenticated

Useful evidence may include:

Contracts, purchase orders, bids, abstracts, vouchers, disbursement records, receipts, inspection reports, and acceptance documents;
Official letters, memoranda, resolutions, minutes, certifications, audit observations, and government records;
Emails, text messages, chat records, photographs, videos, or audio recordings lawfully obtained;
Bank, property, corporate, or transaction records lawfully available to the complainant;
Requests submitted to an agency and proof of receipt;
Written follow-ups and the agency’s replies;
Affidavits from witnesses with personal knowledge; and
A timeline or table connecting each allegation to its supporting annex.

Mark attachments in a consistent sequence, such as Annex “A,” Annex “B,” and so on. Refer to each annex in the relevant paragraph of the complaint.

When using copies, preserve the originals. If a document was obtained online, save the full file, source URL, and access date—not only a cropped screenshot. For emails and messages, retain the original account, conversation context, dates, sender details, and any export or backup available. Do not alter files, add misleading annotations to originals, or secretly obtain material through unlawful access.

A complaint need not prove the entire case at the filing counter, but it should provide verifiable particulars. Under the 2026 Revised Rules of Procedure, a matter may be sent for fact-finding when it contains sufficient leads but is not yet adequate in form or substance for preliminary investigation, administrative adjudication, or forfeiture proceedings.

Step 4: Execute a verified complaint-affidavit

A verification confirms under oath that the allegations are true and correct based on the complainant’s personal knowledge or authentic records. A complaint-affidavit should be signed and sworn before a notary public or another officer legally authorized to administer oaths.

Do not sign the affidavit before appearing before the notary or authorized officer. Bring competent proof of identity and follow the officer’s requirements.

The oath is important. Knowingly making false sworn statements may expose a person to criminal or other legal consequences. Republic Act No. 6770 also penalizes the malicious or grossly bad-faith filing of a completely unwarranted or false complaint. Honest allegations supported by a reasonable factual basis are different from deliberately fabricated claims.

Step 5: Prepare the Certificate of Non-Forum Shopping

For a formal administrative complaint, the current rules require a Certificate of Non-Forum Shopping subscribed and sworn to by the complainant or counsel. The Ombudsman’s public checklist likewise requires a verified certificate as part of the filing package.

In substance, the certificate should disclose whether the complainant has started or knows of another case involving the same issues before a court, tribunal, or quasi-judicial agency; identify any such proceeding; and undertake to report a similar proceeding learned of later.

Disclosure does not necessarily mean that the Ombudsman complaint will be dismissed. Concealing another proceeding is the greater risk. List related complaints, appeals, civil cases, administrative cases, criminal complaints, and agency proceedings, then explain how they relate. A lawyer can determine whether the parties, causes, issues, and relief are legally the same.

Step 6: Make the required copies

Follow the Ombudsman’s current public checklist:

Complaint-affidavit: one copy for every named respondent, plus four;
Originally signed complaint-affidavits: at least two within that set;
Supporting evidence: one complete set for every named respondent, plus four; and
Verified Certificate of Non-Forum Shopping: at least two original copies.

For example, a complaint naming three respondents ordinarily requires seven sets of the complaint and supporting evidence. At least two complaint-affidavits and two certificates should bear original signatures.

Make every set complete, legible, properly paginated, and arranged in the same order. Keep an identical personal copy.

The rules permit complaints in other forms, including complaints that may later require fact-finding, but relying on that flexibility can delay action. When possible, meet the formal requirements at the outset.

Step 7: File with the appropriate Ombudsman office

File with the Central Office or the appropriate sectoral or area office based on the respondent and geographic coverage. Cases involving the military, police, and other law-enforcement personnel may be routed to the Deputy Ombudsman for the Military and Other Law Enforcement Offices.

The Central Office is at:

Office of the Ombudsman Ombudsman Building Sen. Miriam P. Defensor-Santiago Avenue, formerly Agham Road Brgy. Bagong Pag-asa, Diliman Quezon City 1105 Telephone: (+632) 5317-8300

The official directory also lists offices in Cebu City, Iloilo City, Tacloban City, Davao City, Cagayan de Oro City, Rosales, and other locations. Use the official contact directory to find the current address and telephone number.

Before travelling, call the receiving office to confirm:

Which office should receive the complaint;
Current filing hours;
Whether an appointment is necessary;
Whether the office requires a digital copy for a lengthy submission;
Whether a regional, satellite, or assistance center can receive the filing; and
Whether any remote submission method is currently authorized for an original complaint.

Do not assume that a general inquiry email address is an authorized filing channel. If the Ombudsman confirms that filing by mail, courier, email, or an electronic portal is available, follow its exact instructions and preserve proof of transmission and receipt.

Step 8: Obtain and protect proof of filing

Ask for a stamped receiving copy, acknowledgment, reference number, or other official proof showing the date and office of receipt. Record the name of the receiving unit and keep courier records or electronic acknowledgments, if applicable.

The “20 minutes” stated on the Ombudsman’s public filing page refers to the listed service duration for receiving a compliant submission. It is not a promise that the complaint will be investigated or resolved in 20 minutes.

Keep the proof of filing with:

One complete copy of the submission;
The original evidence retained by you;
A list of every annex;
Notarial details;
Later notices and orders; and
Proof of service for any pleading you are subsequently directed to serve.

What happens after filing?

The Ombudsman first evaluates and classifies the submission. It may:

Refer it to the proper Ombudsman sectoral or area office;
Refer it to another agency with exclusive or concurrent jurisdiction;
Treat it as a request for assistance;
Direct a fact-finding investigation;
Docket it as a criminal, administrative, or forfeiture case; or
Dismiss it outright when a recognized ground is apparent.

A referral is not necessarily a finding that the allegation lacks merit. It may mean that another body is the proper or more appropriate forum.

If the matter proceeds as a criminal complaint, the respondent may be required to submit a counter-affidavit and evidence. The complainant may be allowed or directed to reply. Under the 2026 rules, the preliminary-investigation standard is prima facie evidence with reasonable certainty of conviction. This is not the same as a judgment of guilt after trial.

If an administrative case is docketed, the respondent will be given an opportunity to answer. The matter may be resolved on affidavits and position papers or may proceed to clarificatory or formal hearings when necessary. Administrative liability is ultimately determined by substantial evidence.

The Ombudsman—not the complainant—decides whether the evidence supports probable cause, administrative liability, forfeiture proceedings, referral, or dismissal. Filing a complaint does not itself establish guilt, remove an official, or recover money.

Deadlines require special care

There is no single filing deadline that applies to every Ombudsman complaint.

For administrative matters, a filing made more than one year after the complained-of act or omission is a discretionary ground for outright dismissal, not an automatic jurisdictional bar. File as soon as reasonably possible and explain any delay, continuing conduct, concealment, later discovery, or difficulty obtaining records.

For criminal matters, prescription depends on the exact offense and governing law. For example, the prescriptive rules for an alleged violation of Republic Act No. 3019 cannot safely be applied to bribery, malversation, falsification, perjury, or another offense without separately examining that law and the date of the conduct. Questions about when prescription began or was interrupted can also be fact-sensitive.

Do not wait for an internal agency investigation to finish unless a lawyer confirms that waiting will not endanger a criminal, civil, administrative, procurement, election, labor, or judicial deadline.

Once the Ombudsman issues an order or resolution, read it immediately. Under the 2026 revised rules, a motion for reconsideration generally must be filed within a non-extendible 10-day period from receipt, must state the material dates, and must include the required proof or affidavit of service. Only one motion is generally allowed. Appeal routes and periods differ between criminal and administrative matters and may depend on the type of ruling and penalty. Obtain legal advice promptly rather than relying on a general filing guide.

Evidence to preserve while the complaint is pending

Preserve:

Original documents and the devices or accounts where electronic evidence is stored;
File metadata and unedited source files;
Envelopes, delivery receipts, acknowledgment stamps, and email headers;
Names and current contact details of witnesses;
A dated log of later events, contacts, threats, demands, or retaliatory acts;
Copies of public-record requests and responses;
Employment records if retaliation affects your work; and
All Ombudsman notices, including proof of the date each was received.

Do not coach witnesses, coordinate false accounts, publish confidential evidence recklessly, or pressure anyone to sign an affidavit they cannot personally support. Avoid discussing the case on social media, particularly where publication could expose witnesses, compromise evidence, violate confidentiality, or create defamation issues.

Common filing mistakes

Naming an office but not the responsible people

Identify the officials who acted or failed to act and explain each person’s role. If an identity remains unknown, describe the position or function and explain why the name is unavailable.

Submitting conclusions instead of facts

Saying “the bidding was rigged” is not a substitute for stating who prepared the specifications, who submitted bids, what records show common ownership or advance coordination, and how the procurement departed from applicable rules.

Attaching a document dump

Organize the evidence. A short annex index and paragraph-by-paragraph references are more useful than hundreds of unexplained pages.

Using illegally obtained evidence

Unauthorized access to accounts, systems, private communications, or restricted records can create separate legal problems and may compromise the complaint. Use lawful record requests and obtain advice before submitting sensitive material.

Omitting related cases

Disclose related proceedings accurately in the Certificate of Non-Forum Shopping, even if you believe they involve different relief.

Filing too few copies or incomplete sets

Count the respondents carefully and apply the “respondents plus four” rule to both the complaint and supporting evidence.

Assuming an anonymous accusation guarantees an investigation

An anonymous complaint may be considered when it contains sufficient, verifiable leads. An accusation without names, dates, transactions, documents, or a realistic way to verify the claim may be dismissed. An anonymous complainant also cannot expect personal notice of the action taken under the current rules.

Demanding a particular outcome

Ask for investigation and appropriate action under the law. The Ombudsman determines classification, probable cause, liability, penalties, referral, and prosecution based on its authority and the evidence.

When legal help is urgent

Consult a Philippine lawyer promptly if:

A prescriptive period or another filing deadline may be close;
You have received an Ombudsman order, subpoena, counter-affidavit, resolution, or adverse decision;
You are both a complainant and potentially implicated in the transaction;
The evidence includes classified, privileged, bank, medical, tax, personnel, or protected personal information;
Evidence may be destroyed or funds or property may be transferred;
You face threats, harassment, surveillance, dismissal, reassignment, or other retaliation;
The respondent is an impeachable official, legislator, judge, prosecutor, police officer, or military officer and jurisdiction is uncertain;
The same facts are already before a court, prosecutor, administrative agency, Congress, or another disciplinary body;
You seek witness protection, immunity, preventive relief, recovery of property, or an injunction; or
The facts involve several respondents, procurement layers, corporations, intermediaries, or transactions over a long period.

For an immediate threat to life or safety, contact emergency law-enforcement services and obtain legal assistance. An Ombudsman complaint is not a substitute for urgent physical protection.

Frequently asked questions

Who may file?

Any person may file. The complainant need not be a government employee or the direct victim, although personal knowledge and reliable records make a complaint easier to evaluate.

Is a lawyer required?

A lawyer is not generally required merely to submit a complaint; the official filing service is available to any person. Legal assistance is advisable for complex facts, possible self-incrimination, prescription issues, overlapping proceedings, sensitive evidence, or challenges to an Ombudsman ruling.

Must the complaint be notarized?

A complaint may initially be received in another form, but a formal complaint-affidavit should be verified and sworn. A formal administrative complaint requires a sworn Certificate of Non-Forum Shopping. A criminal complaint that is not under oath may lead the investigator to require supporting affidavits before proceeding.

Can I file anonymously?

Yes, but anonymity affects the process. The Ombudsman will act on an anonymous complaint only when it merits consideration or contains sufficient leads or particulars for further action. Under the current rules, an anonymous complainant will not be notified of the action taken.

Can I complain against a private person?

Not for an ordinary private dispute. A private person may be investigated or included when the evidence connects that person to an offense involving a public officer, such as participation or conspiracy in a government-related transaction.

Can I file both criminal and administrative charges?

Yes, when the same facts reasonably support both. State the facts and requested investigation clearly. The Ombudsman will classify the matter and determine which proceedings are warranted.

Should I file with the agency first?

Not always. An internal complaint may be useful for a service grievance or disciplinary matter, but the Ombudsman has independent authority. Exhaustion and adequate-remedy questions can depend on whether the case is administrative or criminal and on the relief sought. Do not delay where prescription, retaliation, or loss of evidence is a concern.

What if I do not yet have every government record?

File the evidence you lawfully possess, identify the missing records precisely, explain who controls them, and provide verifiable leads. The Ombudsman has investigatory and subpoena powers, but it is not required to build a case from a vague accusation.

Will the respondent be arrested after I file?

No. Filing alone does not authorize arrest or establish guilt. A criminal complaint must undergo the legally required investigation and probable-cause processes, followed by court proceedings if an information is approved and filed.

How can I check the case status?

Keep the reference number and use the Ombudsman’s official process for a request for complaint or case information. Access may depend on your identity, role in the case, confidentiality rules, and the stage of proceedings.
