John "Jack" C. Maginnis III
I am admitted to practice law in the District of Columbia, Virginia and Maryland. I am a member of The District of Columbia Bar, the Virginia State Bar and the Maryland State Bar Association and was selected by my peers, as listed in an article published by Washingtonian magazine, as one of the 50 best divorce lawyers. I was also elected to The District of Columbia Bar Family Law Section Steering Committee where I served as co-chairperson.

A Diverse Offering Of Services
As a divorce attorney, I understand that individuals can have varying legal needs. To better serve my clients, I provide assistance in a number of areas, including collaborative divorce, child custody and support matters, prenuptial agreements and same-gender family law cases. I also have extensive experience assisting clients with complicated international divorce cases, including G-4 visa holders and their spouses.

I recognize the challenges that arise in high-asset divorce cases. I boast considerable experience in this area and can help guide you through what can be an especially complex process.
