Mary T. Vidas is an experienced family law attorney based in Philadelphia and a partner with the nationally acclaimed law firm Blank Rome. Focusing primarily on matrimonial litigation, Vidas is AV® Preeminent™ rated by Martindale-Hubbell® and has been listed among Philadelphia Magazine’s "Ten Leaders of Matrimonial Law" in Philadelphia for over a decade.

Now with more than thirty years of practice behind her, Vidas looks back on what initially inspired her to go into family law:

I went to Georgetown University’s school of foreign services but when I graduated there happened to be a hold on hiring new foreign service officers. And so I said to myself at the time, ‘what am I going to do?’ I decided that the next logical step was to go to law school. I enrolled at Temple and absolutely fell in love with the law. I had a great family law teacher, and I really liked litigation, so I decided to remain in that field.

Vidas earned her Juris Doctor from Temple University Beasley School of Law in 1984 and has been providing top-tier representation to clients in a broad range of domestic relations and family law matters ever since. Throughout her career, her practice has touched on divorce, custody and child support, alimony, prenuptial agreements, surrogacy and adoption cases, among others.

Today, Vidas is highly lauded both as a formidable litigator and a skilled and fair-minded negotiator. Certified as an arbitrator by the American Academy of Matrimonial Lawyers, she often seeks to guide her clients away from the stressful experience of going to court. However, should a case need to go to trial, she is ready to fiercely litigate for her clients’ interests in a court of law.

As a leader in her field, Vidas is an active and influential member of the legal community and has held many leadership positions in prominent national and local legal organizations. She is the immediate past chair of the Family Law Section of the American Bar Association and is a past president of the Pennsylvania chapter of the American Academy of Matrimonial Lawyers. Vidas is also widely regarded as an intellectual authority in family law and is a frequent lecturer for the Pennsylvania Bar Institute, the Academy of Matrimonial Law, the Family Law Section of the American Bar Association, and the Pennsylvania Institute of CPAs ("PICPA").

Playing these roles entails that Vidas stay ahead of prevailing trends in the law, policy, and beyond that may affect her practice and clients. Commenting on what is currently capturing her attention, she noted:

I am paying attention to the impact of the new tax reform act on clients. The 2018 Tax and Jobs Act will impact many clients from the loss of the alimony deduction and dependency credits to the potential restructuring and taxation of businesses and trusts. I am also staying up to date on the latest in reproductive technology as it affects same-sex marriage. New technologies are paving the way for same-sex couples to have children, which means that they often need to enter prenups and create parenting plans.

In part due to this focus on same-sex marriage, Vidas was recently honored at the Pennsylvania Diversity Council’s eighth annual Philadelphia Diversity and Leadership Conference alongside fellow Blank Rome partner Attorney Brian Paszamant. The council also named Vidas one of the Most Powerful and Influential Women for 2017.

After more than three decades dedicated to family law, Vidas continues to exhibit exceptional leadership and client service. Showing no signs of slowing down, she looks forward to providing clients with her industry-leading representation and counsel for many years to come.
