How to Fill Out and Submit an Internal Affairs Complaint Form

An internal affairs complaint form is how you formally report police misconduct to the officer’s own department, triggering an administrative investigation that can lead to discipline. Most agencies post the form on their website under a heading like “Internal Affairs,” “Professional Standards,” or “Citizen Complaints,” and accept it in person, by mail, or through an online portal. Forms are not standardized across the country, so the fields and submission rules vary by jurisdiction, but the core structure and the information you need to supply are largely the same from one department to the next.

What to Gather Before You Start

A complaint built on specifics moves faster than a vague one. Before you open the form, pull together whatever you have of the following:

Officer identification: name, badge number, and physical description. Officers typically display this on their uniform. If a patrol car was involved, note the unit number printed on the vehicle.
Date, time, and location: the exact address or intersection and the approximate time. Investigators use this to pull dispatch logs, body-worn camera footage, and nearby surveillance recordings.
A chronological account written while your memory is fresh. Stick to observable facts: what was said, what physical actions occurred, and in what order.
Witness names and contact information. Even partial information helps investigators locate them.
Physical evidence: photos of injuries or property damage, cell phone video, screenshots of messages, and medical records if you sought treatment.

You do not need all of these to file. A complaint with only a date, location, and description of what happened is still valid. But the more identifiers you provide, the easier it is for investigators to match your account against department records.

How to Get the Form

You can usually obtain the form through one of a few channels:

The department’s website, which typically hosts a downloadable PDF or an online submission form.
In person at any precinct, substation, or police headquarters. A city clerk’s office or city hall can often provide one as well.
By phone — call the department’s non-emergency line and request that a form be mailed to you.

Some jurisdictions also accept complaints through a civilian oversight board or independent review authority. If your city or county has one, that office uses its own intake form and can investigate independently of the police department. The National Association for Civilian Oversight of Law Enforcement maintains a directory at nacole.org that can tell you whether an oversight body exists in your area.

Filling Out Each Section

Formats differ, but most internal affairs complaint forms separate your personal information, the officer’s information, the narrative, and a signature block into distinct sections.

Complainant Information

Expect fields for your name, address, phone number, and email. Many departments accept anonymous complaints, but providing contact information lets investigators follow up with questions and notify you of the outcome. If you are filing on behalf of someone else, you will usually need to identify both yourself and the person who experienced the misconduct.

Officer and Incident Details

Enter whatever identifying information you have about the officer or officers involved: name, badge number, physical description, unit number, or the division they appeared to work for. A separate block asks for the date, time, and location. Fill in every field you can, and leave the rest blank rather than guessing.

Narrative Section

This is the core of the complaint. Describe what happened in chronological order, starting with what led up to the encounter and ending with how it concluded. Stick to facts you personally observed. “The officer grabbed my arm and pushed me against the vehicle” is useful. “The officer was being unprofessional” is not, because it tells the investigator your conclusion rather than the conduct that led to it. If the form provides limited space, most departments allow you to attach additional pages.

Witnesses and Evidence

List witnesses by name and contact information. Note any physical or digital evidence you have and whether you are attaching copies. Keep originals for your own records.

Signature and Verification

Most forms include a signature block where you affirm that the information is true and correct to the best of your knowledge. The Port St. Lucie Police Department’s form, for example, requires the complainant to “swear or affirm that the foregoing information is true and correct” and sign alongside a witness signature line.¹ A small number of jurisdictions require notarization. If yours does, a notary public at a bank, shipping store, or courthouse can verify your identity for a few dollars. Date the document, because the filing date can matter for any applicable deadlines.

How to Submit It and Prove You Did

Choose a submission method that creates a record showing the department received your complaint:

Certified mail with return receipt. This gives you a signed receipt showing who accepted the envelope and when. Mail the form to the department’s internal affairs division. Port St. Lucie, for instance, accepts complaints mailed to its Internal Affairs unit or sent to a dedicated email address.¹
Online portal. Many departments offer web-based submission. Baltimore County, for example, uses an online form with fields for contact information, incident details, and a summary. Save or screenshot any confirmation page or reference number the system generates.²
In-person delivery. Bring the form to the internal affairs office or any precinct and ask for a stamped copy or written receipt.
A civilian oversight board, if one exists in your jurisdiction. This routes the complaint outside the department’s chain of command.

Keep a complete copy of everything you submitted. If the department later claims it never received the form, your copy and delivery receipt are your proof.

What Happens After You File

Once the department receives your complaint, it assigns a reference number and typically sends an acknowledgment that includes a summary of your allegations and the name or contact information of the assigned investigator.³ Hold onto the reference number. You will need it to check on the status of your case.

An investigator reviews your complaint, gathers evidence, and interviews the people involved. Expect to be contacted for a follow-up interview where you may be asked to clarify or expand on your written account. You are generally allowed to bring an attorney or another representative, though the department is not required to provide one.⁴ If the person who experienced the misconduct is a minor, a parent or guardian should be present.

Timelines vary. The DOJ’s community policing office recommends that agencies complete investigations within 180 days, while acknowledging that agencies with limited staffing may take longer.³ Complex cases involving multiple officers or extensive video review can push well beyond that window.

When the investigation concludes, the department classifies the result using one of four standard dispositions:³

Sustained: the investigation found, by a preponderance of the evidence, that the officer’s conduct violated department rules.
Not sustained: the evidence was insufficient to prove or disprove the allegation.
Exonerated: the conduct described did occur, but it did not violate department policy.
Unfounded: the investigation determined the allegation was not true.

Most departments notify you of the outcome in writing. Personnel privacy laws in many states prevent the agency from telling you what specific discipline the officer received, so a sustained finding may be all you learn, even if the consequence ran from a written reprimand up to termination.

Filing Deadlines

There is no single national deadline for internal affairs complaints. Each department or jurisdiction sets its own cutoff, and the windows range from months to several years. Filing promptly matters regardless of the formal deadline: witnesses become harder to reach, video footage gets overwritten on a schedule, and details fade. File as soon as you have enough information to describe what happened.

Beyond the Department

The internal affairs process is administrative. It can lead to discipline against the officer, but it does not compensate you for injuries, lost wages, or other harm. Two other avenues exist and do not require you to finish the departmental complaint first.

If the misconduct involves a potential civil rights violation, the DOJ Civil Rights Division accepts reports through an online portal at civilrights.justice.gov. The form walks you through seven steps covering your contact information, the nature of your concern, the location, and the date.⁵ You can file anonymously by leaving the contact fields blank. Federal law also prohibits agencies that receive DOJ funding from retaliating against someone who files a complaint or participates in an investigation.⁶ The FBI investigates “color of law” violations — cases where someone acting under government authority willfully deprives a person of a constitutional right — and takes tips through tips.fbi.gov or any local field office.⁷

If the misconduct caused you measurable harm, you may also have a civil claim under 42 U.S.C. § 1983, which allows individuals to sue state and local officials who violate their constitutional rights.⁸ Separate statutes of limitations apply and vary by state, so an attorney experienced in civil rights litigation can tell you whether the facts of your case support a federal claim and how long you have to bring it.
