THE CRIMINAL DEFENSE PROCESS

A criminal case involves several important stages, and each one can affect the outcome of your defense. From the initial consultation through investigation, arraignment, pre-trial motions, plea negotiations, and trial representation, having a skilled attorney guide you through the process can make all the difference. Understanding what happens at each step helps you make informed decisions and protect your rights from the very beginning.

INITIAL CONSULTATION

The initial consultation is the first step in the criminal defense process, where you meet with an attorney to discuss the details of your case and understand your legal options. During this meeting, the attorney evaluates the facts, answers your questions, and outlines potential strategies moving forward.

CASE INVESTIGATION

Case investigation is the phase where your attorney gathers and reviews evidence, interviews witnesses, and analyzes the facts to build a strong defense. This step is critical for identifying weaknesses in the prosecution’s case and uncovering details that support your side of the story.

ARRAIGNMENT

Arraignment is the court hearing where you are formally charged and asked to enter a plea, such as guilty, not guilty, or no contest. During this stage, the judge may also address bail and outline the next steps in the legal process.

Leopold Gross represented me in a litigation that lasted several years and involved extensive motion practice, a trial, and ultimately an appeal. Throughout the entire process, he was prepared, strategic, and completely committed to getting the right result.In the end, he won the case in its entirety, including successfully overturning an improper ruling by the trial court on appeal. Watching him handle every stage of the case made it clear that he has a level of experience and skill that sets him apart. He's an exceptional trial lawyer and litigator who always seemed a step ahead.Just as importantly, he was straightforward, responsive, and someone I trusted during a long and stressful process.
