Erin Kopelman is a divorce attorney who handles cases involving domestic relations and family law, including divorce, custody, child support, property settlement, alimony, post-judgment issues, prenuptial agreements, and postnuptial agreements in Maryland and the District of Columbia.

Erin is a fierce advocate for those she represents in negotiations and in the courtroom. She is straightforward and communicative, making sure her clients have the information to make the best decisions for themselves and their children. The daughter of two Naval officers, Erin brings a high level of precision and discipline to all her matters.

Erin often represents people with substantial assets or income who have issues related to business valuations, trust interests, or non-marital property. She works with many high-level executives at large companies, independent entrepreneurs, and professionals like attorneys in downtown law firms, as well as their spouses, all of whom value her discretion and her understanding of complex compensation and ownership issues. Erin also handles cases involving support for adult disabled children and domestic violence.

Erin also practices collaborative law and serves as a mediator. The collaborative process allows divorcing couples to work together with their attorneys to create mutually beneficial divorce settlement agreements without going to court. While not appropriate for all couples, in most cases the collaborative process can be transformative and can avoid the escalation of hostility and overwhelming cost inherent in going to court. As a third-party neutral in mediation, Erin assists divorcing couples in reaching negotiated resolutions without messy litigation. In addition, Erin has a certificate in arbitration from the American Academy of Matrimonial Lawyers. Prior to joining Lerch Early, she practiced law at a boutique divorce and family law firm in Montgomery County.

Erin is listed in Best Lawyers in America for Family Law, is listed in Maryland Super Lawyers, and in DC Super Lawyers. The Daily Record named her one of Maryland’s “Leading Women,” and Bethesda Magazine readers gave her the “Family Law Practitioner of the Year” award and she was a “Top Vote Getter” in Bethesda Magazine’s inaugural Top Attorneys list. Active in the Family Law section of the county bar association, she has received both the “Section Chair of the Year” and “Bar Leader” awards.

Erin loves to exercise, plus the peace and beauty of being out on the water while kayaking and stand-up paddle boarding is an added bonus. When she can’t be on the water, Erin enjoys walking in her neighborhood or on the treadmill.
