Most people do not know they have the option of a defense attorney before charges are filed.
By the time an arrest is made, a DA reviews the case, and a complaint lands in court, the narrative has already been shaped largely by law enforcement and prosecutors, with no input from the defense.
Pre-file intervention is the strategy that changes that dynamic. It is the process of retaining experienced criminal defense counsel the moment you learn you are under investigation, and working proactively with detectives, prosecutors, and the District Attorney's office to influence whether charges are filed at all.
In California, where prosecutors have broad discretion in charging decisions, the pre-file window is often the most leveraged moment in the entire criminal process.
Once charges are filed, the defense responds. Before they are filed, the defense can still shape the outcome. Eisner Gorin LLP is here to help you. Schedule your consultation by calling (818) 781-1570.
What Is Pre-File Intervention?
Pre-file intervention is legal representation that begins during the investigation phase, before any criminal complaint has been filed with the court. It is sometimes called pre-filing representation or pre-charge defense.
The core activities in a pre-file intervention engagement include:
- Establishing attorney-client privilege immediately, which limits what the client communicates directly to investigators.
- Opening a professional channel of communication with the investigating detective or law enforcement agency.
- Gathering and preserving exculpatory evidence before it is lost, overwritten, or unavailable.
- Preparing and submitting a pre-file presentation or memorandum to the prosecuting agency.
- Negotiate directly with the DA's office to prevent filing, secure a reduced charge, or arrange a civil compromise where applicable.
- Advising the client on whether and how to cooperate with investigators without creating additional exposure.
The goal is to insert the defense into the process early enough to change the outcome, not just respond to it.
Why Does the Pre-File Stage Matter So Much in California?
California prosecutors are not required to file charges simply because law enforcement makes an arrest. The DA's office conducts its own review and exercises independent discretion over what to file, how to file it, and whether to file at all.
That discretion is the opening that pre-file intervention is designed to exploit.
Several factors make early intervention particularly valuable in California:
- The 48-hour rule: Under California law, if a defendant is arrested and held in custody, the DA has 48 hours to file charges, or the defendant must be released. A defense attorney engaged at the investigation stage can often prevent an arrest from occurring in the first place.
- Prosecutorial discretion is real and exercisable: DA offices across Los Angeles, Orange County, and the broader California system make charging decisions based on evidence strength, victim cooperation, witness reliability, and the overall likelihood of conviction. A well-prepared pre-file presentation directly addresses each of those factors.
- First impressions with the DA are durable: The framing prosecutors receive from law enforcement shapes how they approach a case from the start. Defense counsel who can present an alternative factual narrative early can interrupt that framing before it hardens into a charging decision.
Who Benefits Most from Pre-File Intervention?
Pre-file intervention is appropriate in any investigation, but is particularly critical for certain categories of clients.
Individuals who benefit most include:
- High-profile defendants: Professional athletes, executives, entertainers, and public figures for whom an arrest alone, regardless of outcome, carries irreversible reputational and professional consequences.
- Licensed professionals: Physicians, attorneys, contractors, financial advisors, and others whose licenses are at risk the moment a criminal filing occurs.
- White-collar targets: Individuals under investigation for fraud, embezzlement, tax offenses, or regulatory violations, where the investigation period can span months before any arrest.
- Defendants with strong exculpatory evidence: Cases where surveillance footage, digital records, financial data, or witness accounts clearly support innocence but have not yet been presented to prosecutors.
- Cases involving credibility disputes: Allegations that rest heavily on a single accuser's account, where early investigation can surface inconsistencies before the DA commits to a filing.
What Does a Pre-File Presentation Include?
A pre-file presentation is a formal submission to the DA's office, or in some cases directly to law enforcement, designed to make the case against filing charges. It is not a trial brief, nor an argument to a judge.
It is a persuasion document directed at the people who control whether the case exists at all. An effective pre-file presentation may include:
- A factual summary that presents the defense version of events, supported by evidence.
- Documentation challenging the credibility or reliability of the complaining witness or key evidence.
- Legal analysis explaining why the alleged conduct does not meet the elements of the charged offense.
- Character and background evidence establishing the client's standing in the community.
- Evidence of the investigation's gaps, procedural errors, or constitutional violations.
- In appropriate cases, proposed alternatives to prosecution, such as civil resolution or diversion (examples of pretrial diversion programs include Mental Health Diversion under PC 1001.36, Judicial Diversion under PC 1001.95, and Military and Veteran Diversion under PC 1001.80).
The strength of the presentation depends entirely on how quickly counsel is retained and how aggressively the defense investigates during the pre-file window.
Frequently Asked Questions(FAQs)
What is pre-file intervention in California criminal cases?
Pre-file intervention is a defense strategy in which a California criminal defense attorney becomes involved during the investigation stage, before formal criminal charges are filed.
Why is pre-file intervention important?
Early intervention may help prevent criminal charges, avoid arrest, preserve favorable evidence, and influence prosecutorial charging decisions before a case reaches court.
What is the goal of pre-file intervention?
The primary goal is to stop charges from being filed or reduce potential criminal exposure before prosecutors formally initiate a criminal case.
When should I hire a criminal defense attorney during an investigation?
You should contact an attorney immediately if you believe law enforcement is investigating you, requesting records, contacting witnesses, or attempting interviews.
Can a lawyer stop criminal charges from being filed?
In some cases, yes. Defense attorneys may persuade prosecutors not to file charges by presenting exculpatory evidence, legal defenses, or weaknesses in the investigation.
What is a pre-file presentation?
A pre-file presentation is a formal submission to prosecutors explaining why charges should not be filed or why alternative resolutions may be appropriate.
What may be included in a pre-file presentation?
Presentations may include factual summaries, legal analysis, challenges to witness credibility, surveillance evidence, financial records, constitutional arguments, and mitigation materials.
What types of cases benefit most from pre-file intervention?
Pre-file intervention is especially important in white collar crimes, domestic violence investigations, fraud cases, sex crime allegations, professional licensing matters, and high-profile investigations.

Preventing a Fraud Filing Against a Financial Executive – a Hypothetical Case Study
Outside counsel informed a senior executive at a Southern California investment firm that federal agents had contacted the firm's compliance department and were requesting records related to the client's trading activity.
No arrest had been made. No charges had been filed. But the pattern of the inquiry suggested a securities fraud investigation was underway.
Defense counsel was retained within 48 hours of that notification. The pre-file strategy unfolded in three phases:
- Immediate evidence preservation: Counsel identified and secured internal communications, trade records, and compliance documentation that directly contradicted the government's apparent theory of the case.
- Proactive engagement with investigators: Rather than allowing the investigation to proceed without defense input, counsel established a communication channel with the investigating agency and signaled that the client was prepared to provide context, on carefully structured terms, that would affect the charging analysis.
- Pre-file memorandum to the U.S. Attorney's office: A detailed factual and legal submission demonstrated that the trading activity in question was consistent with publicly available information and the client's documented investment strategy, and that no insider access had been involved.
No charges were filed. The investigation was closed. The client's career and professional reputation remained intact, and there was no public record of the investigation.
What Should You Do If You Believe You Are Under Investigation?
The single most important step is to retain counsel immediately. Not after the arrest. Not after the target letter arrives. The moment you have reason to believe law enforcement is looking at you, your communications, your finances, or your conduct.
In the meantime:
- Do not speak to investigators without an attorney present.
- Do not contact potential witnesses, alleged victims, or co-targets.
- Do not delete, alter, or move any documents, communications, or records.
- Do not discuss the matter on any platform where communications are not privileged.
Each of these steps, if taken before counsel is retained, can independently complicate or foreclose options that would otherwise be available.
Pre-File Intervention in High-Profile and Complex Cases
For clients where an arrest itself is the catastrophe, regardless of what follows, the pre-file stage is the only stage that matters.
A public arrest ends careers, destroys business relationships, and generates headlines that no acquittal will fully erase. The most effective defense is the one that ensures no charges are ever filed, no arrests are ever made, and no public records are ever created.
