If you need someone to represent you in DuPage County for criminal court, Mike is the best lawyer you can call — hands down. I don't believe I could have had a better outcome with anyone else.

Mike and Jes are truly the best. I've used other attorneys in the past and it was a huge mistake. Mike saved my license, kept me driving, and cleaned up my past record with an expungement. I highly recommend him.

"In domestic cases, the state pursues charges even when the alleged victim doesn't want to. The accusation alone can cost you your home, your children, and your firearm rights before you ever see a courtroom."

— Mike McMahon, Former DuPage County Prosecutor

Domestic Violence Defense Overview

Domestic Violence Defense from a Former Prosecutor

A domestic violence charge in DuPage County can mean restraining orders issued before you have a chance to speak, loss of your firearm rights, removal from your own home, and a permanent criminal record that follows you on every background check — including custody proceedings.

Most clients we represent are decent people facing false or exaggerated allegations. They were involved in heated arguments that escalated beyond control. They were accused by vindictive partners during contentious separations. Or they acted in self-defense during genuinely threatening situations. A domestic violence accusation does not define who you are.

Mike McMahon prosecuted domestic violence cases for the state. He knows how prosecutors build these cases, what evidence they rely on most heavily, and where those cases are most vulnerable. Judge Pierce presided over domestic violence trials for decades and knows what evidence gets excluded and what arguments create reasonable doubt in DuPage County courts.

We fight to get domestic violence charges dismissed, reduced, or beaten at trial. We challenge false allegations, self-defense situations, insufficient evidence, and constitutional violations in every case — and we work to get emergency protection orders lifted when they are based on exaggerated or fabricated claims.

We Prosecuted Domestic Violence Cases

Mike McMahon built domestic violence cases for the state. He knows precisely how prosecutors use police reports, 911 recordings, and medical evidence — and exactly where those cases are most vulnerable to challenge.

02

We Expose False Allegations

Domestic accusations are frequently driven by custody disputes, contentious separations, and revenge. We investigate the accuser's motives, prior false reports, inconsistent statements, and history of manipulation to expose fabricated claims in court.

03

We Assert Self-Defense

Illinois law recognizes the right to defend yourself against domestic threats. We investigate every case for legitimate self-defense claims, gather evidence of prior threats or violence by the accuser, and build the factual record that supports your version of events.

04

We Challenge Orders of Protection

Emergency orders are issued without you present, based solely on the accuser's account. They can remove you from your home and cut off contact with your children overnight. We appear at plenary hearings to challenge orders built on exaggerated or false allegations and fight to get them lifted.

05

We Know DuPage County Judges

Judge Pierce decided domestic violence cases from the bench for decades. He knows what evidence gets excluded, what arguments resonate with every judge in Wheaton, and how to position cases for the best outcome in DuPage County domestic courts.

06

We Protect Your Gun Rights and Custody

A domestic battery conviction triggers a federal lifetime firearm ban under the Lautenberg Amendment and can devastate your custody position. We pursue outcomes — dismissal, supervision, or charge reduction — specifically designed to protect your rights, your record, and your relationship with your children.

FAQ

Questions People Ask
After a Domestic Violence Arrest

Straight answers. No legalese.

Do not make any statements to police beyond your identifying information, and do not contact the alleged victim — even to clear up a misunderstanding. An automatic no-contact order is almost always issued at arrest, and any contact can result in additional charges that stack on top of the original case. Call an attorney immediately. The state pursues domestic battery cases aggressively regardless of what the alleged victim wants, and the first hours after arrest are the most important for protecting your rights and addressing any emergency protection orders.

Not automatically. In Illinois, the decision to prosecute belongs to the state's attorney, not the alleged victim. Prosecutors routinely pursue domestic battery cases even when the complaining witness recants or refuses to cooperate. That said, a non-cooperative victim creates significant problems for the prosecution — it removes their key witness and often makes proving the case at trial extremely difficult. We work with the complete picture, including the alleged victim's position, to identify the strongest path toward dismissal or reduction.

An order of protection is a civil court order that prohibits contact with the protected person and can remove you from your shared home. Emergency orders are issued the same day the petition is filed — without you present — based solely on the petitioner's allegations. They are temporary, typically lasting 14 to 21 days. A plenary order of protection hearing must be scheduled, and that is where you have the right to appear, present evidence, and challenge the allegations. We appear at plenary hearings to cross-examine the petitioner and argue against entry of the order when it is based on exaggerated or false claims.

Yes — permanently. Under the federal Lautenberg Amendment, any misdemeanor domestic battery conviction results in a lifetime ban on firearm possession. This applies regardless of whether the charge is a misdemeanor or felony, and it cannot be expunged or pardoned away under federal law. If you hold a FOID card or concealed carry license, those are revoked upon conviction. Protecting your firearm rights is one of the most important reasons to fight domestic battery charges rather than accept a plea — and we build every defense with that consequence in mind.

Yes, significantly. Illinois family courts are required by law to consider domestic violence findings when determining parental responsibilities and parenting time. A conviction or even an active order of protection can result in restricted or supervised visitation and can shift the custody determination heavily against you. Many domestic allegations arise directly from contentious custody disputes. We coordinate your criminal defense with an awareness of the family court implications, pursuing outcomes that protect both your criminal record and your parental rights.

Domestic battery is a Class A misdemeanor for a first offense and involves bodily harm or physical contact of an insulting or provoking nature with a family or household member. Aggravated domestic battery is a Class 2 felony and requires either great bodily harm, permanent disability or disfigurement, or strangulation. The strangulation element is critical — any allegation of choking, even without visible injury, can elevate a misdemeanor domestic battery to a non-probationable felony. The distinction determines whether prison time is mandatory and how significantly the charge impacts your firearm rights, custody case, and permanent record.

Violating a no-contact or order of protection — even accidentally — is a separate criminal charge that stacks on top of your original case. A first violation is a Class A misdemeanor. A second or subsequent violation where the protected person suffered injury is a Class 4 felony. The fact that the alleged victim initiated contact is not a defense under Illinois law — the order binds you, not them. Call us immediately. We can work to have the underlying order modified or contested at a plenary hearing, and we build a defense around the circumstances of the alleged violation.

Misdemeanor domestic battery cases in DuPage County typically resolve within 3 to 9 months. Felony aggravated domestic battery cases can take 12 to 24 months depending on the evidence, whether expert witnesses are needed, and whether the case goes to trial. Protection order hearings move much faster — a plenary hearing is typically scheduled within 30 days of the emergency order being issued. We give you a realistic timeline at your free consultation based on your specific charges, the evidence in your case, and the court where your matter is filed.
