Marie I Crossley

About me


         My focus in every case is my client and how to achieve their goals.  While I have extensive trial and litigation experience, I am also trained in Mediation/Alternative Dispute Resolution. Particularly in the area of Family Law, the ability to effectively negotiate is just as important as trial advocacy and my mediation background allows me to tailor my approach to my client's individual needs.



         I have been practicing Family Law exclusively for 15 years in the state of Delaware.  After graduating from Washington & Jefferson College in 1998, I attended Villanova University School of Law.  After graduating from Villanova, I clerked for the Honorable William L. Chapman and the Honorable Alison Whitmer Tumas, State of Delaware Family Court.  I am a partner at MacElree Harvey and manage the Centreville Delaware office.

    I endorse this lawyer. Ms. Crossley contacted my law practice to refer a client. I sincerely appreciated not only the referral but the professionalism she displayed. Ms. Crossley was able to provide me with a brief, yet concise, background of the matter while simultaneously explaining the jurisdictional roadblocks she anticipated in her home state of Delaware. It is truly an honor to work with professional and knowledgeable attorneys both intrastate and interstate. I would highly recommend her services!
