Prefiling intervention in California is criminal defense work undertaken before a prosecutor formally files criminal charges. A defense attorney may investigate the accusation, preserve favorable evidence, advise about investigator contacts, and decide whether a carefully supported presentation could affect the charging decision.
It is not a guaranteed way to stop a prosecution, and it is not a program created by Penal Code 849.5. Robert M. Helfend’s guidance on the investigation stage emphasizes getting advice before an informal conversation or attempted apology creates evidence that cannot later be taken back.
How prefiling intervention in California works
The process begins with understanding what has happened: an allegation, police contact, an arrest, a search, a subpoena, or referral to a prosecuting agency. An arrest and a filed criminal charge are different events. A booking description can also differ from the charges ultimately filed.
Investigation and evidence preservation
Police collect information and may send a case to a prosecutor for review. A criminal defense attorney can identify evidence that the initial investigation missed or interpreted incorrectly, such as complete message threads, camera footage, transaction records, witness accounts, or an independently supported timeline.
Preservation is often urgent. Cameras overwrite footage, records become harder to obtain, and memories fade. Give your defense attorney the original material and where it came from. Keep unfavorable material as well; editing a conversation or deleting records can create a different problem.
Review by the prosecuting agency
The prosecutor generally makes the charging decision. Government Code 26500 identifies the district attorney as the public prosecutor, except as otherwise provided, and assigns discretion to initiate and conduct prosecutions. A detective’s opinion about likely charges is not a filed complaint or a binding promise about the outcome.
A presentation to the district attorney’s office may identify a missing element, mistaken identity, a reliable alternative explanation, or a significant evidentiary problem. Your defense lawyer must consider both its potential value and the risk of unnecessarily disclosing a defense theory, an admission, or unverified information.
The charging decision
The agency may decline to file, ask for further investigation, file a different or lesser charge, or proceed with the proposed accusation. A decision not to file at one point is not always permanent. Reconsideration and legal filing deadlines depend on the offense and circumstances.
If formal charges are filed, the work already done can still help with release, discovery, motions, negotiation, and trial preparation. Once a case is filed, a request to dismiss it uses a different procedural setting. See the firm’s guide to dismissal of criminal charges.
What early defense work can accomplish
Avoiding an unsupported charge
Reliable physical evidence and other exculpatory evidence can change how an accusation is assessed. The useful question is what the evidence actually proves, not whether the client can offer a forceful denial. A camera timestamp, for example, needs to be checked against the camera’s clock and the relevant sequence.
Correcting the proposed charge
Even when a criminal case remains possible, the facts may not support the initial severity or every proposed count. A discussion about a lesser charge should address its record, immigration, licensing, and other consequences rather than treat a misdemeanor label as harmless.
Assessing alternatives
Treatment, counseling, or another response may be relevant in an appropriate case. Formal pretrial diversion is a separate process with its own eligibility and court requirements. Prefiling intervention does not automatically provide diversion or an entitlement to dismissal.
Protecting practical interests
Early advice can help a person manage investigator contacts, evidence preservation, employment concerns, and immediate safety or protective-order issues. Public exposure cannot be guaranteed to disappear, and counsel cannot promise that an arrest will leave no record.
When to consider prefiling intervention
Seek advice promptly if a detective asks for an interview, you learn that someone reported you, officers arrest and release you without a filed case, or you receive a warrant-related or subpoena document. You do not need to wait for an arraignment to consult retained counsel.
False allegations, disputed identity, misunderstandings, incomplete digital communications, alleged financial intent, and search issues can merit early investigation. A mental health condition or trauma history may be relevant, but it is not automatically a defense. The evidence and legal purpose of any evaluation should be considered with counsel.
The timing can be short in an in-custody case. California’s prompt court-appearance requirements after arrest are different from the deadlines for prosecuting a released person. Follow any notice to appear, and have counsel verify the case status rather than assume a missed anticipated filing date means the allegation is over.
Helfend on responding to investigators
In his investigation-stage explanation, Helfend discusses the detective’s call as a common point when a person first realizes an allegation is being investigated. His practical advice is to obtain legal guidance before discussing the accusation.
An invitation to “tell your side” can feel like an opportunity to settle a misunderstanding. An unprepared answer can instead introduce an inconsistency, speculation, or an unintended admission. Investigators collect evidence; their interview is not a private defense consultation.
Voluntary interviews and compulsory process are different
Counsel can assess whether an interview is voluntary and whether to participate, decline, or proceed under a considered arrangement. That advice does not mean ignoring a subpoena, resisting a lawful search, or obstructing officers. Give legal process to counsel promptly so its scope, deadline, and response can be addressed.
Do not lie if you choose to speak. State and federal false-statement or obstruction issues can create exposure separate from the allegation under investigation. When declining a voluntary discussion, a brief request to speak with an attorney is more useful than a detailed unadvised explanation.
How a federal investigation may differ
A target letter can provide notice of a federal investigation, but not every person under investigation receives one. A target and a subject are different designations, and receiving a subpoena does not by itself establish either status. The firm’s target-letter guide discusses that setting.
Counsel may communicate with the investigating or prosecuting agency about status and available information. A person does not automatically receive the complete investigative file before a charge is filed. Decisions must account for what is known and what remains unavailable.
Helfend’s warning about pretext calls and written apologies
In his discussion of being investigated before charges, Helfend identifies a particular risk in sex-offense investigations: a call or request for a written apology may be arranged to obtain corroboration. The conversation can sound personal while serving an investigative purpose.
An apology intended to end a dispute can be interpreted as acknowledging conduct, depending on its wording and context. Do not assume that an informal call, text, or social-media exchange is confidential or separate from the investigation. Preserve the full exchange and obtain advice before responding about the allegation.
This does not mean every call is a police operation or that declining to discuss an allegation guarantees there will be no charge. It means a decision about communications should be deliberate. Do not contact, pressure, pay, or ask another person to influence the complainant or a witness. Follow any protective or no-contact order.
Making useful information available without an unprepared interview
Helfend’s distinction between the investigator and the charging agency helps explain the role of prefiling counsel. The attorney can evaluate reliable records and determine whether a presentation to the appropriate agency has value. The client need not try to settle the entire accusation in a spontaneous phone conversation.
A useful initial consultation identifies who contacted you, the exact words used, any deadline, what you already said, and the evidence needing preservation. Tell counsel about difficult facts as well as favorable ones. An assessment based on an incomplete account can lead to a poor decision about what to disclose.
What Penal Code 849.5 actually says about arrest records
Penal Code 849.5 addresses a person who was arrested and released without an accusatory pleading being filed. It requires the arrest record to include the release and provides that the arrest is thereafter deemed a detention only. It does not create a prefiling intervention program.
That provision is also different from sealing arrest records. Eligibility, exceptions, and the procedure under Penal Code 851.91 require separate review. A decision not to file should be documented, but a person should not assume that every government or background-check record automatically disappears.
Preparing for a criminal defense consultation with Helfend
Bring arrest, release, citation, warrant, subpoena, or investigator-contact documents.
Write a factual timeline, distinguishing what you saw from what someone else told you.
Identify complete messages, relevant accounts, camera locations, records, and possible witnesses.
List conversations you already had with police, the complainant, or other witnesses.
Explain any protective orders, upcoming court dates, employment concerns, or licensing issues.
Ask what can be verified now, what remains unknown, and whether a presentation is appropriate.
A useful plan identifies the next action and its purpose: preserve footage, obtain a record, assess a requested interview, verify filing status, or prepare a supported submission. The measure of good early work is an informed, defensible decision, even when the prosecutor ultimately files charges.
What changes if misdemeanor or felony charges are filed?
Early intervention and a filed prosecution involve different decisions. In Los Angeles County, identify the court, case number, actual counts, and first court date. If a defendant is held in county jail, release and the immediate hearing schedule become urgent. A felony case may proceed to a preliminary hearing; a misdemeanor ordinarily follows a different route.
At trial, the prosecution must prove guilt beyond a reasonable doubt. That is different from probable cause and the standards used at earlier stages. A defense lawyer should explain what the prosecution’s evidence establishes, what remains disputed, and which procedure can address each issue.
A request to suppress evidence under Penal Code 1538.5 addresses search-and-seizure questions through the proper court procedure. A Penal Code 995 motion concerns specified defects in an indictment or commitment after a preliminary hearing. Neither is the definition of prefiling intervention, and a detective cannot grant a court motion.
A plea agreement, if considered later, requires a separate assessment of the evidence, potential sentence, and consequences for the client’s personal and professional life. Criminal defense lawyers should not treat a quick resolution as sufficient merely because the initial effort to prevent filing was unsuccessful.
Frequently asked questions
Can a lawyer stop charges before they are filed?
A lawyer may investigate, preserve evidence, advise about communications, and present reliable information that could affect the prosecutor’s decision. There is no guarantee that charges will be prevented, and a presentation is not appropriate in every case.
Is prefiling intervention a program under Penal Code 849.5?
No. Section 849.5 concerns arrest and release records when no accusatory pleading is filed. Prefiling intervention describes defense work before charges; it is distinct from formal diversion and arrest-record sealing.
Does being released without charges mean the investigation is over?
Not necessarily. The prosecutor may seek additional investigation or file later within applicable legal limits. Follow any notice to appear and ask counsel to verify the status and relevant deadlines.
Should I explain my side to the detective before hiring a lawyer?
Obtain advice before discussing the allegation in a voluntary interview. Counsel can assess the risks and whether reliable information should be presented another way. Do not ignore compulsory process, obstruct a lawful search, or lie.

"Fights for Justice"
Robert Helfend is an amazing criminal defense attorney. I have him on 2 different cases and finally got to see him in action at our preliminary. Which isn't even over yet, but just from that so far, I'm incredibly impressed. His passion to fight for justice for his clients, in my opinion separates him from other attorneys. He really goes in there and fights to his best ability for you. He's seen how I was dragged along into this case which had nothing to do with me, and how my children were dragged into it as well and since then he's done so much to help us. We will forever be so grateful and appreciative with Mr. Helfend. You will not be disappointed, but you will regret it if you don't get him!
