How Criminal Defense Lawyers Build a Case – Key Strategies Explained
If you are charged with a crime, it can be difficult to trust the attorney you hire. Your life is on the line with the outcome of the legal proceedings, and it is easy to think that your lawyer is there simply to collect a paycheck. The reality is, a lawyer can be the most vital key to a successful outcome based on how criminal defense lawyers build a case to argue your side of the story.
Understanding How Defense Lawyers Build a Case
There are many steps a criminal defense attorney in California will take to build a strong case. These steps serve the interest of their clients. While some attorneys use a standard formula, a strong criminal defense attorney will approach these steps with their clients’ unique needs in mind.

Evaluating Evidence and Independent Investigation
During this phase, your lawyer reviews all initial police reports, eyewitness statements, video footage, and other forensic evidence to identify potential weaknesses in the prosecution’s case. The attorney may also see that witnesses are reinterviewed, alibis are verified, and locate any proof that may have been overlooked. If necessary, professionals may also be contacted for their insights into highly specific knowledge.
Aggressive Pretrial Motions
In this step, your defense attorney works to get all relevant evidence from the prosecution. Your legal counsel may also file a motion to dismiss if they believe there is insufficient evidence or a motion to suppress evidence if they believe evidence was obtained illegally.
Establishing a Defense Strategy
The attorney works directly with their client to understand their side of the story and identify potential defense approaches, such as arguing for mistaken identity, self-defense, or providing an alibi. During this step, your lawyer explains your rights, the potential consequences if convicted, and discusses with you what may be the ideal way to progress the case.
Plea Negotiations
In many cases, a defense attorney tries to bargain with the prosecution in order to secure reduced charges, lesser penalties, or alternative sentencing. Under some circumstances, it may also be possible for an attorney to advocate for a diversion program, which focuses on rehabilitation rather than incarceration.
In 2024, the rate of arrests in California was 2,069 arrests per 100,000 residents, with more than 810,000 arrests across the state that year. Of those arrests, approximately 261,400 were for felony offenses. If you or a loved one has been arrested, it is imperative to consult a defense attorney as soon as possible so they have the maximum amount of time to build a compelling case on your behalf.

More serious cases, including felony offenses, may instead be processed at the Criminal Division of the Pomona Courthouse South.
Depending on the details of your case, the courthouses or other venues you may interact with over the course of the proceedings can vary. Be sure to confirm with your criminal defense lawyer the addresses of any relevant locations.

FAQs About How Criminal Defense Lawyers Build a Case in California
Is It Worth Challenging a Criminal Charge in CA?
It can certainly be worth challenging a criminal charge in the state of California. Criminal penalties can be severe, so it is often worth working with an experienced defense attorney to protect yourself from unnecessarily harsh punishment. Even if you and your legal team ultimately decide to pursue a plea bargain to potentially reduce the penalties, this would be a stronger strategy compared to simply accepting the charges against you without providing input on the matter.
What Are Common Defense Strategies in CA?
In California, there are several defense strategies that an attorney can use. Some common strategies include asserting the defendant was mistakenly identified or had an alibi at the time of the crime, arguing that the prosecution lacks sufficient evidence for a conviction, establishing that the defendant acted in self-defense, in the defense of others, or based on a mistake of fact, and proving that the defendant’s constitutional rights were violated, whether through unlawful search and seizure, entrapment, or coercion.
What Are the Main Types of Pleas in California?
In California, the main types of pleas you can submit to the court are guilty, not guilty, and no contest. A guilty plea is the defendant admitting they committed the crime as charged. In a not guilty plea, the defense denies committing the crime. A no-contest plea involves the defendant not admitting guilt but still accepting the conviction and subsequent punishment. Less common pleas include a former conviction or acquittal, once in jeopardy, and not guilty by reason of insanity.
How Much Does a Criminal Defense Lawyer Cost?
The legal costs of a criminal defense attorney in California depend on the complexity of the case, the attorney’s experience, and where you are located. The most effective way to get an accurate estimate for attorney fees is to consult your legal counsel. Some law firms have an hourly rate, while others may offer a flat fee for certain services.
