Any criminal offense which involves an alleged victim with whom you’ve had, or are having, an intimate relationship will be designated as a domestic violence (DV) crime in Colorado.  Because of the unique bond restrictions placed upon those arrested for a DV offense, the decision of many prosecutors to “fast-track” DV cases through the court system, and the penalties associated with conviction of a DV-related crime, it is crucially important that you know the lay of the land from an experienced Boulder domestic violence lawyer when charged with a criminal offense that is tagged as a DV offense.

Not being fully informed and provided with a competent defense by an experienced domestic violence attorney can have far-reaching consequences in a DV case. Do you have weapons for self-protection and home defense?  Colorado law requires that guns, rifles, and ammunition be surrendered when you are charged with a DV offense. And your Second Amendment rights can be permanently imperiled by a DV conviction.

Other areas of concern that need to be discussed and strategized with your Boulder domestic violence attorney include bond restrictions that include exclusions on where you live, limitations on contact with your spouse or significant other, supervised retrieval of your belongings after being barred from a home that you shared with the alleged victim, and common post-arrest restrictions on seeing and parenting children.


If you are a student or employee in a college or university setting and you’ve been notified that a complaint has been made against you by another student or member of the campus community which involves sexual assault or harassment, you will soon be dealing with a group of investigators who operate under the acronym of OIEC, the Office of Institutional Equity and Compliance. The OIEC is charged with enforcing provisions of Title IX, the federal law that requires schools receiving federal funding to prevent and address issues regarding sexual misconduct/harassment in campus-related matters.

Please know that there is danger ahead anytime you have an OIEC complaint pending. And it is pivotally important to have an experienced Boulder OIEC Defense Lawyer assisting you with your case, particularly since OIEC matters are often referred to law enforcement agencies and that referral may result in criminal charges being brought against you for the same conduct under review by the OIEC.

A timely investigation led by your OIEC defense team is a pressing part of establishing and proving favorable facts since most OIEC investigative teams do not record their interviews or make the statements of your alleged victim and witnesses available to you until much later, if ever (and then typically in a redacted format).  With due process in short supply in OIEC matters, it is all-important that you have an experienced team on your side.

The OIEC Defense Lawyers at Mertes Law also handle Colorado student school district conduct complaints across the Front Range, including those involving assault and sexual conduct matters.
