Marie I. Crossley Partner


“Marie is an honest and trustworthy lawyer. She is meticulous and thorough when going through case material. Marie fights to get what is in the best interest of her client. Her knowledge of the legal system and laws is unmatched. Marie is genuinely caring and knows how to handle the delicate situations that arise in family court matters. I highly recommend Marie and intend on utilizing her for my legal needs going forward.” – Client Review from Avvo 

Marie I. Crossley has practiced exclusively in the Delaware Family Law arena for over 16 years. She handles a wide variety of Divorce, Custody, Child Support, Alimony and other Family Law matters ranging from the mediation of small disputes to complex Divorce, Custody and Support litigation.

Marie has recently added Mediation to her practice to accommodate clients who are looking for an alternative to the adversarial nature of traditional Divorce, Custody and Support litigation. Marie works out of the Centreville, Delaware office at MacElree Harvey, Ltd.

Marie graduated from Villanova University School of Law in 2001.  She clerked for the Honorable Alison Whitmer Tumas and the Honorable William L. Chapman of the Delaware Family Court until entering private practice in 2002.  Marie spent ten years as a Family Law Attorney, and then Partner, of a Wilmington Delaware Law Firm until joining the Family Law Group at MacElree Harvey, Ltd.

Marie prefers to be directly involved in every aspect of her client’s matter and feels that communication is the foundation of any successful attorney-client relationship.  She works with each client directly providing legal advice and guidance tailored to their specific case.
