Admitted to practice law in New Jersey and Virginia

Allison Mattia Roberts is a graduate of George Washington University Law School in Washington, D.C., and obtained her undergraduate degree at Northwestern University in Evanston, Illinois. She returned to her home state of New Jersey in 2006 and since then has acquired extensive experience, including regular court appearances in criminal and family matters in Superior, Juvenile and Municipal courts.

Ms. Roberts recently was asked to co-chair the Cannabis Committee for Hunterdon County as laws pertaining to marijuana legalization shift and change in our state. A member of the Family Law Practice Committee in Hunterdon County, she continues to serve as a panelist on the Matrimonial Early Settlement Panel.

During the 2010 State Bar Convention in Atlantic City, Ms. Roberts moderated a panel entitled “Handling Criminal and Family Cases in Superior Court: Tips on Practice and Pitfalls for Young Lawyers.”

Former Prosecutor

Five years of experience as a prosecutor in Arlington County, Virginia, where Ms. Roberts appeared in court virtually every day to handle domestic violence cases, facilitated a natural transition into all aspects of family law here in New Jersey.

As just one example of her work in family law, when she appeared before the Court of Appeals in Trenton on behalf of a victim of domestic violence, the court upheld the validity of the Final Restraining Order issued to protect her client.

The expertise Ms. Roberts gained from years of prosecuting cases and trying them before a jury has been essential to her work handling contested trials in Superior and Municipal courts in New Jersey.


Ms. Roberts gives each and every client the attention and respect they deserve. Whether it is the identification and valuation of complex financial assets or if it is assisting families in financial distress to find a practical way to move forward, she works closely with her clients and, when needed, experts in the areas of forensic accounting, real estate appraising, and bankruptcy. While it is always the goal to achieve a settlement, Ms. Roberts’ extensive trial background provides an understanding of what the focus needs to be in your case during negotiations.

Criminal Matters and Domestic Violence

Ms. Roberts also represents defendants in criminal matters and domestic violence hearings. Some defendants face the serious consequences that accompany a final restraining order. Other defendants are unjustly accused by individuals seeking to gain an advantage in a divorce. It is critical for all of these defendants to have a skilled, experienced trial attorney representing them – an attorney like Ms. Roberts, who will not back down and will take the case to a hearing.

Often, domestic violence cases will be the first step toward divorce. Ms. Roberts has experience handling the entire spectrum of divorce litigation, from matters that are resolved amicably in informal negotiations to financially complicated cases requiring the services of an expert forensic accountant. She has addressed such considerations as State Police and teacher pensions, as well as family businesses and real estate investments, as part of the equitable distribution of marital assets.

Children and Custody

Ms. Roberts works diligently for her clients when children and custody are at issue. In such cases, she often assists clients when a Best Interest Custody Evaluation by a mental health professional is required before any arrangements can be made for parenting time and custody.

Ms. Roberts regularly prepares post-judgment motions for existing and new clients. These motions address violations of matrimonial agreements, changes in circumstances that will affect custody and child support, and other enforcement issues following a divorce.


Palimony, a claim for support between unmarried individuals, is an area in which Ms. Roberts has gained notable expertise. A significant change to the state’s Statute of Frauds governing contracts for Palimony in 2010 has monumentally impacted this area of family law, and, in such cases, it is essential to retain an attorney who knows the nuances surrounding these claims for support.

Juveniles and Families in Crisis

Ms. Roberts has a particular passion for handling matters involving juveniles and families in crisis. She has extensive experience working with the Division of Child Protection and Permanency (formerly the Division of Youth and Family Services, or DYFS) in multiple counties across the state. In many cases where parental rights have been challenged by the state through DCPP, Ms. Roberts has been able to protect those rights by guiding families to reunification – or kinship placement when necessary. Her goal is always to see that any family or child in crisis gets the support and services needed with minimal government intrusion.

DUI, Traffic Offenses, Drug Charges

Ms. Roberts also has successfully represented clients charged with driving under the influence (DUI), employing experts when needed to avoid lengthy license suspensions. She appears regularly in local municipal courts for traffic and minor drug charges, particularly with youthful offenders. She has successfully appealed convictions at the municipal court level to achieve acquittal and justice for her clients in Superior Court.


In addition to regular appearances in court, Ms. Roberts assists her clients with expungements when eligible. This is an area of law that has recently expanded and changed to the benefit of many of her clients.  

Outside work, Ms. Roberts is actively involved in youth sports as a parent, coach and board member. She served as an attorney coach to the Voorhees High School Mock Trial Team and has repeatedly appeared at area high schools for Law Day presentations. Ms. Roberts is a member of the Hunterdon Networking Associates and serves on the Acorn Montessori School Executive Board in Hunterdon County, and her family is actively involved with The Red Mill Museum in Clinton.
