About Us

Momjian Anderer LLC is a boutique law firm focusing on complex family law matters, including divorce, property division, child custody, support, and alimony.  We assist clients from both traditional and non-traditional families, offering expertise in all facets of domestic relations, from family-formation (adoption and paternity) to the drafting of prenuptial and postnuptial agreements.  Our goal is to help clients reach amicable agreements, but if that is not possible, we provide vigorous advocacy in trial and appellate courts, as well as in alternative-dispute resolution settings, such as binding arbitration.

Our firm uses sophisticated knowledge and decades of experience to address the challenging financial issues faced by clients in high-net worth cases.  We assemble teams that may include forensic accountants, business appraisers, and other valuation experts who can assist in negotiation and testify at trial.  In child custody matters, including child custody relocation, we work with psychologists and other mental health experts to prepare effectively for negotiation and trial.

Our lawyers are leaders and active members of state and local bar associations.  We teach, lecture and publish in the field of family law.  We are recognized in Best Lawyers in America, Pennsylvania Super Lawyers, and U.S. News & World Report.  And many public-interest organizations have recognized our pro bono work on behalf of the indigent, seniors, domestic-violence victims, and the LGBTQ+ community. 

We regularly deal with cutting-edge issues involving social media, electronic surveillance, and biotechnology that intersect with family law.  Our lawyers have handled pioneering cases in Pennsylvania, including successfully defending the constitutionality of the Grandparents' Visitation Act before the Pennsylvania Supreme Court and winning the first appellate case in the United States in which a non-biological parent was directed to pay child support to her former domestic partner.  The American Law Institute, the leading independent organization in the U.S. producing scholarly work to clarify and modernize the law, honored Momjian Anderer LLC by asking it to produce an eight-hour Continuing Legal Education program on the fundamentals of Pennsylvania family law. 

Momjian Anderer LLC is based in Philadelphia, but our lawyers have appeared in courtrooms throughout the Commonwealth, representing clients in more than 25 judicial districts, from Philadelphia to Erie Counties.
