Reasons to File a Complaint Against an Opposing Attorney

If a lawyer on the other side of your case has crossed from hard advocacy into actual misconduct, filing a complaint against an opposing attorney is handled by the disciplinary agency in the state where that lawyer is licensed. Every state has one, and every state accepts complaints from anyone affected by the attorney’s conduct, including the opposing party.1American Bar Association. Lawyer Licensing A complaint puts the attorney’s license on the line. It will not win your case or get you money back.

Conduct That Justifies a Complaint

Not every annoying or aggressive move by opposing counsel is reportable. The disciplinary system responds to specific violations of the professional conduct rules. The categories below are the ones that come up most often.

Lying to the Court or to You

Lawyers owe candor to the tribunal. They cannot make false statements of fact or law to a judge, and they cannot present evidence they know is fabricated.2American Bar Association. Model Rules of Professional Conduct Rule 3.3 – Candor Toward the Tribunal A forged exhibit, a misrepresented witness statement, or a knowingly bad citation to overturned law all fall inside this rule.

Dishonesty outside the courtroom is also misconduct. The rules separately prohibit any conduct involving dishonesty, fraud, deceit, or misrepresentation.3American Bar Association. Model Rules of Professional Conduct Rule 8.4 – Misconduct An attorney who lies about a material fact during settlement talks, or invents a deadline to pressure you into signing, can be reported even though no judge was present.

Contacting You Without Your Lawyer’s Permission

If you have counsel, the opposing attorney cannot communicate with you directly about the case unless your lawyer consents or a court authorizes it.4American Bar Association. Model Rules of Professional Conduct Rule 4.2 – Communication with Person Represented by Counsel The contact itself is the violation. The content doesn’t change that.

Common examples: calling you to pitch a settlement, emailing you to urge acceptance of a deal, or walking up to you in a courthouse hallway to talk about the case. If it happens, don’t engage. Tell them to contact your attorney, save the message or write down what was said, and alert your lawyer the same day.

Frivolous Filings and Discovery Abuse

Some attorneys use the process itself as a weapon. Filing motions or claims with no non-frivolous basis in law or fact—purely to run up costs or wear you down—is a recognized violation. The same is true of frivolous discovery requests, refusals to respond reasonably to legitimate discovery, and obstructing access to evidence.5American Bar Association. Model Rules of Professional Conduct Rule 3.4 – Fairness to Opposing Party and Counsel A baseless counterclaim filed to force a nuisance settlement, boxes of irrelevant document demands, ignored production deadlines, and coached misleading testimony are all reportable.

Harassment and Discrimination

Zealous advocacy has limits. The rules treat it as misconduct for a lawyer to harass or discriminate on the basis of race, sex, religion, national origin, disability, sexual orientation, gender identity, or socioeconomic status in conduct related to the practice of law.3American Bar Association. Model Rules of Professional Conduct Rule 8.4 – Misconduct A separate rule bars conduct intended to disrupt court proceedings.6American Bar Association. Model Rules of Professional Conduct Rule 3.5 – Impartiality and Decorum of the Tribunal

Demeaning remarks about your race or gender during a deposition, threats meant to intimidate you, screaming personal insults at a hearing—none of these serve any legitimate legal purpose, and bar authorities take complaints about them seriously.

Conflicts of Interest

If the lawyer now opposing you once represented you, that may itself be grounds for a complaint. A lawyer who previously represented a client generally cannot later represent someone with adverse interests in the same or a substantially related matter without the former client’s informed, written consent, and cannot use confidential information from the earlier representation against the former client.7American Bar Association. Model Rules of Professional Conduct Rule 1.9 – Duties to Former Clients

This surfaces often in smaller legal markets. If the opposing lawyer once advised you on a related deal, reviewed your financial records, or handled a dispute involving the same property or contract, there’s likely a conflict. Your own attorney can also raise the conflict directly with the court to get opposing counsel removed, which is usually faster than the disciplinary route.

Criminal Conduct

A crime that reflects on an attorney’s honesty or fitness to practice is misconduct even when it has nothing to do with your case.3American Bar Association. Model Rules of Professional Conduct Rule 8.4 – Misconduct Embezzlement, tax fraud, DUI, and drug offenses regularly produce bar discipline. If you learn the opposing attorney has been arrested or is under investigation, you can tell the bar. The disciplinary process is separate from criminal prosecution, though. The bar can suspend or revoke a license; it cannot bring charges. Report suspected crimes to law enforcement as well.

Bar Complaint or Court Sanctions

Before you file anything, understand the difference between the two tools available. They do different things, and only one can get you money.

A bar complaint triggers a disciplinary investigation aimed at the attorney’s license. Outcomes range from a private reprimand to disbarment. The process produces no financial recovery for you. It exists to protect the public.

Court sanctions can shift costs. In federal court, a judge can sanction a lawyer who files frivolous pleadings and order payment of part or all of the fees and expenses the violation caused.8Legal Information Institute. Federal Rules of Civil Procedure Rule 11 – Signing Pleadings, Motions, and Other Papers A separate federal statute allows courts to order an attorney who unreasonably multiplies proceedings to personally pay the excess costs and fees.9Office of the Law Revision Counsel. United States Code Title 28 Section 1927 State courts have their own analogous rules. Your attorney files a motion, the judge decides, and the opposing lawyer or firm may be ordered to pay.

If the misconduct is driving up your legal bills right now, ask your lawyer about sanctions first. A sanctions motion addresses the current case. A bar complaint addresses the attorney’s fitness to keep practicing. They aren’t mutually exclusive, and the same conduct often supports both.

Gather Evidence Before You File

A documented complaint gets taken seriously. A vague one about rudeness usually doesn’t. Collect your supporting materials first.

Save every email, letter, and text from the opposing attorney, especially anything that shows the misconduct directly. If they contacted you without your lawyer’s permission, the message itself is your best proof. If they misrepresented facts during negotiations, the correspondence showing the false statement is central.

For anything that happened in court, order the official transcript from the court reporter or clerk. Transcripts are far more credible to investigators than your recollection.

Build a chronological log. For each incident, record the date, time, place, exactly what was said or done, and anyone else present. Stick to facts. “On March 12, Attorney Smith told me in the courthouse hallway that I should accept the settlement or ‘things would get much worse'” is useful. “Attorney Smith has been harassing me for months” is not. Note contact information for any witnesses—the bar may want to reach them.

Pull the attorney’s full name, firm, and bar number. Every state bar runs an online attorney directory. The bar number also appears on court filings in your case.

How to File

Every state bar’s website explains how to file an ethics complaint, though the agency goes by different names from state to state—Office of Disciplinary Counsel, Office of Attorney Regulation Counsel, State Bar Grievance Committee, among others. Search the bar’s site for “file a complaint” or “attorney discipline” to find the correct office and form.

Most state bars accept complaints through an online portal where you upload the form and attachments. Some still require paper. If you mail yours, use a method that gives you proof of delivery, and follow any formatting or file-size rules the bar sets for electronic submissions.

You should receive an acknowledgment with a case or file number. That confirms the complaint is in the system; it does not mean an investigation has started. Keep copies of everything and use the case number on all later correspondence.

What Happens After You File

Intake staff screen the complaint to see whether the alleged conduct, if true, would violate the professional conduct rules. Complaints that don’t describe a specific violation, or that are really about losing a case or disliking the legal system, get dismissed at this stage.

If your complaint clears intake, the bar notifies the opposing attorney and sends them a copy. The attorney gets to submit a written response. Depending on the state, you may or may not see that response.

When the matter needs a closer look, an investigator is assigned. That can involve interviewing witnesses, collecting documents, and taking sworn testimony. Timelines vary widely. Some investigations close within months; complex ones involving multiple clients or cases can run well over a year.

Possible outcomes include:

  • Dismissal, when the bar finds insufficient evidence of a violation.
  • Private reprimand, a confidential warning that doesn’t appear in public records.
  • Public censure, a formal and publicly recorded finding of misconduct.
  • Suspension, in which the attorney temporarily loses the right to practice.
  • Disbarment, a permanent loss of the license.

In most states, proceedings stay confidential unless the bar imposes public discipline. From the outside, a private reprimand and a dismissal can look identical because neither appears on the public record.

If the Bar Dismisses Your Complaint

Many states allow a review or appeal. The process varies, but typically you submit a written appeal within a set window—often 30 days—explaining why the dismissal was wrong. Some states route the appeal to a hearing committee or review panel that can reopen the investigation. A few allow further appeal to the state supreme court, though courts rarely overturn a bar’s dismissal unless the decision was clearly unreasonable.

A dismissal doesn’t necessarily mean the bar found the attorney blameless. It can mean the evidence was thin, the conduct didn’t fit a specific rule, or the matter was outside the bar’s jurisdiction. If you have new evidence that wasn’t in your original filing, include it on appeal.

What a Complaint Will and Won’t Do

A bar complaint protects future clients and the integrity of the profession. It will not award you damages, reduce your legal bills, change the outcome of your case, or force the opposing attorney to settle. If you want financial compensation for harm an attorney caused, that’s a separate civil case, typically a legal malpractice or fraud action.

Filing won’t slow down or interfere with your active case either. Some state bars hold off investigating until the underlying matter is resolved so they don’t disrupt the court proceedings. Don’t wait to document the misconduct, but understand that the bar may not act until your case is over.

Retaliation worries people. An opposing attorney who learns about a complaint against them is unlikely to be pleased, but retaliating against someone for filing a good-faith ethics complaint would itself be a serious violation. Document any retaliatory behavior and report that too. If the original conduct is bad enough to report, the risk of annoying the attorney is not a reason to stay silent. That is precisely what the disciplinary system is for.
