Trenton Office

Trenton Criminal Attorneys

July 2017 brought a beautiful and historic 3 story Victorian Building in Trenton into the HCK fold.  Located on the corner of Parkside and West Main Street, in the lovely Berkeley Square section of the city, the office is convenient to the State Buildings and courthouse, has ample parking, and is easy to find from Routes 295 or 29. Public transportation also makes this an attractive location for many of our clients.

This very large office will be a tremendous resource to clients in the Trenton and surrounding community.  Anchored by core members of our Criminal Defense and immigration teams, we will also have on-site personal injury/negligence attorneys. Since this office will also feature video conferencing, all of the HCK attorneys in other offices will also be available to our Mercer County clients.

Trenton proper has a long history, dating back to the early 1700s. The site of many historical events, Trenton was the site of George Washington’s first victory in the Revolutionary War, the Battle of Trenton, which occurred on Dec 26, 1776.

The city serves as the capital of New Jersey and briefly served as the capital of the United States. Trenton has many venues of historic interest, dating back 300 years. A vigorous historical society works to protect the city’s heritage. The 1719 William Trent House Museum and the Alexander Douglas House are two sites that you may wish to visit. The area where the office is located was established as an early planned suburban community in the early 1900s when such communities were new and unusual.

In addition to its history, Trenton has a number of modern-day attractions.  The Trenton Thunder is the farm club for the NY Yankees; a home game offers a wonderful family adventure. The Sun National Bank Center hosts a myriad of concerts and other events. Several museums, including the NJ State Museum with its planetarium and fine art collections, round out opportunities for visitors. We look forward to greeting you in our Trenton office and encourage you to take some time to explore and enjoy the city after your law firm visit.

accused of:

Assault and Battery – Our Trenton assault attorneys represent individuals charged with simple assault, aggravated assault, battery, and other violent crimes. These crimes can carry months, years, or decades of prison time, and building an effective defense requires an intimate understanding of the facts and legal issues at hand.
Drug Charges – Marijuana possession, cocaine distribution, methamphetamine manufacturing, and other drug charges also carry severe penalties under New Jersey law. If you have been charged with any type of drug-related offense, it is important that you speak with a Trenton drug charge lawyer promptly.

Police Misconduct – We represent officers charged with all forms of police misconduct. If you have been accused of unlawful arrest, using excessive force, sexual harassment, or any other violation of your official duties, a Trenton police misconduct attorney at Helmer, Conley & Kasselman, P.A. can fight to help protect your career and your
Sexual AssaultSexual assault allegations can have immediate and lasting
consequences. Whether you have been accused by a family member, intimate partner, or anyone else, you will need to work with an experienced Trenton sexual assault attorney who can assert your legal rights and execute a strategic defense.
Shoplifting, Robbery, and BurglaryShoplifting, robbery, and burglary charges can range from low-level disorderly person offenses to first-degree indictable crimes. Penalties can range from months to decades in prison and from thousands to hundreds of thousands of dollars in fines.
White Collar Crimes – Our Trenton white collar crime attorneys defend individuals who have been charged with embezzlement, money laundering, identity theft, public corruption, and other similar types of crimes. If you are facing charges, it is imperative that you speak with a lawyer as soon as possible.

Other Crimes – From arson to weapons offenses, our lawyers represent individuals charged with a broad range of other crimes in Trenton as well. If you are facing prosecution for any alleged crime under New Jersey law, we strongly encourage you to speak with one of our lawyers in confidence.

Domestic Violence

If you have been accused of domestic violence by a spouse, partner, former spouse or partner, or anyone else, these allegations can have severe consequences. You can face a domestic violence restraining order before your case goes to trial; and, depending on the circumstances
involved, you could face other pre-trial consequences as well. If your case goes to trial and you get convicted, your conviction will impact virtually all aspects of your life for years to come.

With this in mind, it is critical that you get help from a Trenton domestic violence attorney as soon as possible. When you choose Helmer, Conley & Kasselman, P.A., our attorneys will get to work defending you right away. We will conduct an investigation to gather as much evidence as possible, and we will do everything we possibly can to ensure that you do not suffer unjust consequences due to false, exaggerated, or unwarranted accusations.

In New Jersey, cases are prosecuted as domestic violence when they involve crimes committed (or allegedly committed) against family members and certain other protected individuals. As a result, many different crimes can be prosecuted as domestic violence depending on the circumstances involved. This means that the potential penalties in domestic violence cases vary widely—from a $500 fine and 30 days in jail to a $200,000 fine and life behind bars.

DUI/DWI Defense

Under New Jersey law, it is illegal to drive with a blood alcohol concentration of 0.08 percent or above (if you are over 21) or while under the influence of alcohol. This means that prosecutors do not need evidence of your BAC to secure a conviction. Of course, if the police tested your BAC, prosecutors will use your breathalyzer reading against you—unless your Trenton DUI attorney can keep your test results out of your case.

Challenging your BAC reading is just one of several potential defenses our attorneys may be able to assert on your behalf. When you choose Helmer, Conley & Kasselman, P.A. to represent you, our attorneys will thoroughly analyze all possible defense strategies. Depending on the facts of your case, we may be able to help you avoid unnecessary penalties, or we may be able to help you avoid a DUI conviction entirely.

If you are entitled to a “not guilty” verdict in your DUI case, you need to fight for this verdict by all means available. Beyond potential fines and jail time, a DUI conviction can have many other consequences as well; and, in New Jersey, DUI convictions are not eligible for expungement.


While DUI convictions are not eligible for expungement, many other types of convictions are. If you have questions about clearing your record, or if you need help navigating the process, a Trenton expungement attorney at Helmer, Conley & Kasselman, P.A. can help.

There are several benefits to expunging your criminal record in New Jersey. Once the process is complete, your record will be “extracted and isolated” from the state’s public records system. This means that information about your past conviction will no longer be available to police, prosecutors, employers, landlords, lenders, educational institutions, or other entities. It should also be noted that expungement frequently results in individuals being able to purchase firearms (some convictions will bar someone from having a gun and/or prevent them from getting a gun purchase permit). As a result, getting your record expunged is truly like getting a fresh start, and you owe it to yourself to do everything you can to move on from your conviction as soon as possible.

Family Law

Whether you are preparing to adopt or get married, contemplating a divorce, or dealing with the New Jersey Division of Child Protection and Permanency (formerly known as the Division of Youth and Family Services (DYFS)), you need an experienced Trenton family lawyer who can guide you every step of the way. Our family lawyers and Trenton DYFS lawyers have been representing local residents for decades, and we can rely on this experience to help you make
informed decisions with your—and your family’s—best interests in mind.

Within our family law practice, we provide skilled, personalized and compassionate legal representation for individuals facing all types of family-related legal matters. This includes matters such as:

Child Custody and Support
DYFS Matters
Emancipation of Minors
Parenting Time and Visitation
Prenuptial Agreements

Many people aren’t sure when they should hire a Trenton family lawyer. Oftentimes, people only seek professional help after trying and failing to handle a complex legal matter on their own. If you think you may need help, the odds are that you probably do, and we encourage you to schedule a time to discuss your legal needs with one of our lawyers in confidence.

Immigration Law

A Trenton immigration lawyer at Helmer, Conley & Kasselman, P.A. can help you whether you are seeking to secure lawful immigration status or you need to fight to avoid removal from the United States. Our lawyers also provide legal representation for foreign nationals facing criminal charges in Trenton. The services we offer at our Trenton office include providing legal representation for:

Adjustment of Status Applications
Asylum Applications
Employment-Based Immigration
Inadmissibility Waivers
● Lawful Permanent Resident (Green Card) Applications
● Removal Defense (Fighting Deportation)
● Visa Applications
Visa Extensions
● Other Immigration Matters

United States immigration matters are often extremely complicated, and the outcome of your application, hearing, or other matter could impact your life—and your loved one’s lives—for years or decades to come. With this in mind, it is important to ensure that you are making informed decisions based on sound legal advice. We can help you understand your situation and the options you have available, and we can help you make the right choices for you and
your family.

Traffic Court Defense

In New Jersey, traffic violations carry steep penalties. From speeding to careless driving to failure to appear, all types of violations present risks for fines, surcharges, increased insurance premiums, and other consequences. If you accumulate too many points, you could lose your driver’s license; and, if you get caught driving on a suspended or revoked license, the consequences can become even more severe.

Fortunately, it is possible to fight many types of tickets with the help of an experienced Trenton traffic violation attorney. If you can’t avoid penalties entirely, your lawyer may be able to substantially reduce the consequences of your ticket. As a result, even if you got caught breaking the law, you should not simply pay your ticket and move on. To find out what our lawyers can do for you, schedule a confidential initial consultation at Helmer, Conley & Kasselman, P.A. today.
