Pro Bono

In addition to her private pro bono cases, Michelle has volunteered as a pro bono attorney for many years at the Volunteer Legal Services of Central Texas representing clients in divorce and child custody and child support proceedings.


Michelle and her husband, both originally from the Houston area, have one daughter who is graduating from college this spring. While she’s away at school, they’re looking after (and spoiling) her lab Nancy Indiana Drew - better known at the dog park as Indy. If you see Michelle around the courthouse (you’ll recognize her by her signature cowboy boots), she hopes you’ll say hello and introduce yourself.

Michelle M. Kostun


Michelle has been a lawyer for almost 20 years and practices family law exclusively. A fierce advocate in contested hearings and a shrewd and tough negotiator in family law mediations, she is dedicated to helping her clients solve difficult problems.

Educational Background

Michelle earned her J.D. from Benjamin N. Cardozo School of Law where she graduated magna cum laude in the top 5% of her class in 2001. She received a number of academic honors, including the Order of the Coif, and membership on the staff of the Cardozo Law Review. Focused on advocacy and courtroom skills, Michelle was an active member of the nationally competitive Trial Team, and received advanced training through the school’s Intensive Trial Advocacy Program.

In addition to excelling academically, Michelle worked advocating for families and fundamental rights. Through her work in the Battered Women’s Advocacy Program, she appeared in court on behalf of domestic violence survivors to obtain orders of protection and provide guidance on navigating the legal process. As part of the Innocence Project, Michelle helped wrongfully convicted individuals prove their innocence using DNA testing. In her role as Research Assistant to Professor Barry Scheck, she researched policy issues and assisted with presentations on New York State’s legislative efforts establishing a DNA database, and worked on several high-profile cases where DNA testing and evidence were at issue.

Legal Experience

Michelle started her legal career at Fried Frank, a top international law firm, where she represented some of the world’s largest companies, financial institutions and investment firms in mergers and acquisitions, securities compliance, and private equity and capital markets transactions. She began in the firm’s New York office, and then, as the youngest associate ever to do so, moved to firm’s dynamic and high profile London office. Although the work was interesting and challenging, Michelle knew her true calling was trial work. She transitioned to commercial and business litigation and spent the next several years representing clients in litigation matters in state, territorial, and federal courts in the U.S. Virgin Islands and Texas.

Wanting to use her experience and skills helping individuals and families rather than businesses, Michelle started her own firm in 2007. Since then, her practice has been solely focused on family law matters. In 2011, Michelle stepped away from her firm and joined the Law Office of Becky Beaver, representing clients in cases involving high net-worth and complex marital estates and high-conflict child custody disputes. In 2012 she returned to her own firm and continues to devote her time exclusively to family law. Michelle is experienced in the courtroom, having handled many contested temporary and final orders hearings in divorce proceedings and child custody, child visitation, and child support cases. She also has significant experience settling difficult cases in mediation.

Michelle is particularly experienced and skilled in preparing witnesses to testify at depositions and court hearings and in cross-examination of witnesses. In addition to representing her own clients, she is hired by other family law attorneys to prepare their witnesses for testifying.
