If your insurance company has accused you of submitting a false claim — denied your claim citing suspected fraud, opened an SIU investigation, sent you a recorded statement request, or referred your file to the California Department of Insurance — there’s something important to understand about where you are in the process. An SIU investigation isn’t the same as criminal charges. Not yet. The carrier’s special investigations unit is building a file. The CDI Fraud Division may or may not get involved. The Riverside County District Attorney’s Southwest Office may or may not eventually file a criminal complaint. The work that happens during this pre-charging window — before any criminal case is opened — often determines whether a criminal case ever opens at all. As a Murrieta criminal defense attorney for over 25 years, Nic Cocis has handled insurance fraud accusations at every stage, but the highest-value defense work in these cases happens before charges file, not after.
If you’ve been accused of insurance fraud in Murrieta, Temecula, Menifee, Lake Elsinore, Wildomar, Winchester, Canyon Lake, or French Valley, any eventual criminal case would be heard at the Southwest Justice Center in Murrieta. This page covers the pre-charging investigation phase specifically — what an SIU investigation actually is, what triggers one, what the carrier and investigators are looking for, what to do (and not do) when contacted, why recorded statements are dangerous, and how the defense window narrows once a criminal complaint is filed. For the broader framework on California insurance fraud after charges file — including PC § 550 penalties, defense strategies, and resolution paths — see the firm’s fraud practice area and the white collar crimes practice area.

The Critical Distinction: Investigation Is Not Criminal Charges
The single most important thing to understand about your situation is this distinction. Being accused by an insurance carrier of fraud is not the same as being charged with a crime, and the difference matters enormously.
An SIU investigation is a private investigation by the insurance company’s special investigations unit. The SIU is a department within the insurance carrier (or in some cases a contracted third party). Its purpose is to evaluate claims for indicators of fraud, gather evidence, and either deny the claim or pay the claim. SIUs do not have the power to arrest you, charge you with a crime, or compel your testimony.
A CDI Fraud Division investigation is a state administrative investigation by the California Department of Insurance’s Fraud Division. CDI investigators do have law enforcement authority and can build a case for criminal referral, but they don’t themselves file criminal charges. Their work product gets referred to a prosecuting agency.
A criminal investigation by the District Attorney is what happens after SIU and/or CDI work product gets referred for prosecution. The DA’s office reviews the file, decides whether to file criminal charges under Penal Code § 550 or related statutes, and either declines the case, files misdemeanor charges, files felony charges, or returns the file for additional investigation.
These three phases — SIU, CDI, DA — often run sequentially over a year or more. People sometimes assume “the insurance company is investigating me” means “I’m being charged with a crime any day now.” That’s not how it works. The investigation can go on for months while the carrier builds a file. During that entire period, the defense window is open, and the strategic value of early intervention is at its highest.
How an SIU Investigation Begins
Most SIU investigations don’t begin with someone being caught red-handed. They begin with pattern indicators — facts about the claim that match statistical patterns the insurance industry has associated with fraudulent claims. When a claim hits enough indicators, the carrier opens an SIU file. Many of these claims are completely legitimate; the indicators are imperfect screening tools, not proof.
Common triggers for an SIU referral:
- Claims filed soon after policy purchase or coverage increase. Statistically associated with planning fraud, but also completely normal in many legitimate situations.
- Multiple recent claims or claims with similar patterns. Repeat claimants face elevated scrutiny even when each individual claim is legitimate.
- Credit problems or recent financial stress. Job loss, bankruptcy filings, mortgage defaults, and similar financial events trigger SIU review on the theory that financial pressure correlates with fraud motivation.
- Recent altercations or civil disputes. Pending divorces, custody battles, business disputes, and other interpersonal conflicts can trigger SIU review.
- New policy holders. Carriers screen new policy holders more aggressively for the first year or two of coverage.
- Property condition inconsistencies. A vehicle claim where the carrier’s investigator notices rust patterns, prior body damage, or other indicators that the alleged loss may have been preexisting.
- Medical injury claims with limited objective evidence. Soft-tissue injuries, generalized pain conditions, and other diagnoses that don’t appear on imaging are scrutinized more heavily.
- Tips from third parties. Estranged spouses, business competitors, former employees, and others who have personal reasons to report claimants generate substantial SIU referral volume.
Once an SIU file opens, the investigation typically involves social media review, background research, interviews with witnesses identified through public records, and — in many cases — surveillance of the claimant. The work product is documented, dated, and preserved for potential criminal referral.
What the SIU Is Actually Looking For
Understanding what the SIU is trying to prove helps explain why certain things (recorded statements, social media activity, inconsistent descriptions of the loss) matter so much.
The statutory elements of insurance fraud — under PC § 550, Insurance Code § 1871.4, and related statutes — require the prosecution to prove the defendant knowingly made a material false or fraudulent statement, with the intent to obtain (or deny) a benefit. The SIU is building evidence on each of these elements:
- Knowledge. Did the claimant know the statement was false at the time it was made? Inconsistencies between statements made at different times suggest knowledge. A claimant who says one thing in a recorded statement and a different thing in a later examination under oath has demonstrated that they’re shaping their story — evidence of knowledge.
- Material falsity. Was the statement actually false, and would the falsity have mattered to the carrier’s decision? Small inaccuracies that wouldn’t have changed anything aren’t material. The SIU works to establish that misrepresentations actually affected the claim outcome.
- Intent to defraud. Did the claimant intend to obtain a benefit they weren’t entitled to? Pattern evidence — multiple claims, surveillance of the claimant doing things inconsistent with the claim, financial pressure motives — all support intent.
The defense response works on the same elements in reverse. Good faith disagreement isn’t fraud. A claimant who genuinely believed their version of events was accurate, who genuinely believed their loss was covered, or who genuinely misunderstood the disclosure requirements has a defense that goes directly to the knowledge and intent elements. Mistaken statements aren’t fraud. Memory errors, paperwork confusion, and reliance on others to fill out documents can all defeat the knowing-falsity element. Immaterial inaccuracies aren’t fraud. Even when something stated wasn’t perfectly accurate, if it wouldn’t have changed the claim outcome, the materiality element fails.
The work in the pre-charging phase is largely about establishing the factual record that supports these defenses before the SIU’s narrative gets locked in.
What to Do When an SIU Investigator Contacts You
Contact from an SIU investigator typically takes one of a few forms: a letter requesting a recorded statement, a phone call asking to schedule an “interview,” a visit to the home or workplace, or a notice that the carrier is conducting an examination under oath (EUO) under the policy.
The general rule for every form of contact is the same: do not engage substantively until you have spoken with counsel.
This advice runs against most people’s instincts. The instinct is to “clear things up” — to explain, to provide context, to answer questions because you have nothing to hide. The problem is that even completely truthful explanations can hurt. Three specific reasons:
The SIU has information you don’t. Investigators routinely have witness statements, surveillance video, records from other sources, and pattern data that the claimant doesn’t know about. Statements made without knowing what the SIU already has can contradict evidence in ways the claimant doesn’t realize, and contradictions become evidence of knowing falsity.
Memory is unreliable. People being interviewed under stress often misstate details — sequence of events, dates, specific words used in earlier conversations, descriptions of property or injuries. Inconsistencies between an SIU-recorded statement and an earlier statement to the claims adjuster (or in a police report, or in initial paperwork) become exhibits at trial.
SIU interviewers are trained to elicit damaging statements. SIU interviewers are not adversarial in the way criminal interrogators are. They’re friendly, sympathetic, “trying to understand your side.” That’s not because they’re on the claimant’s side. It’s because friendly rapport produces more talk, more detail, and more inconsistencies than confrontational questioning does. Statements obtained this way are no less admissible than confrontational statements.
The right response to SIU contact is courteous, brief, and consistent: “I’d like to cooperate with your investigation, but I’d like to consult with my attorney before answering questions or giving any statement. Please direct all further communication to my attorney.” Then stop. Don’t elaborate. Don’t justify. Don’t apologize. Just provide the attorney’s contact information and end the conversation.
The Recorded Statement Problem
Recorded statements deserve their own treatment because they are the single most common evidentiary problem in insurance fraud cases.
A “recorded statement” is exactly what it sounds like: an audio or video recording of the claimant answering questions about the claim. Carriers routinely take recorded statements early in the claims process — often before the claim has been formally denied, often before the claimant has any idea their claim is being investigated for fraud. The carrier presents the recorded statement as a normal part of the claims process. In some cases it is. In cases where the SIU has flagged the claim, the recorded statement is functionally an interrogation.
Three things make recorded statements particularly dangerous:
They’re verbatim. Unlike notes from a phone conversation or an investigator’s summary of an interview, recorded statements capture exactly what was said. Every uncertain pause, every “I think,” every revision and clarification is captured. Any prosecutor can play the recording back to a jury or judge.
They lock in the narrative early. A recorded statement taken weeks or months after the loss event captures the claimant’s memory of events at that moment. Later, when more details emerge or memory clarifies, any new version of events appears as an inconsistency. The first recorded statement often functions as the prosecution’s anchor for the entire case.
They cover ground the claimant doesn’t realize matters. Carriers ask questions during recorded statements that seem irrelevant or routine but are actually probing for fraud indicators — financial circumstances, prior claims history, recent purchases, employment status. Answers to these questions become evidence on the intent element if the case develops further.
The policy “duty to cooperate” complicates this. Most insurance policies contain provisions requiring the insured to cooperate with the carrier’s investigation. This creates pressure to give recorded statements. The strategic response is to cooperate appropriately while protecting the criminal defense. This is exactly the kind of decision that requires defense counsel — typically not the same attorney who would handle a civil coverage dispute. A criminal defense attorney with experience in insurance fraud cases can coordinate with civil counsel to manage the duty-to-cooperate obligation while protecting against criminal exposure.
The Pre-Charging Defense Window
The pre-charging window — the period between SIU contact and the filing of a criminal complaint — is the most valuable defense opportunity in any insurance fraud case. Three reasons:
No formal charges yet means no formal record yet. Once a criminal complaint is filed, the existence of the charges becomes part of the defendant’s record even before any conviction. The arrest appears on background checks. The case becomes searchable in court records. The professional licensing implications start immediately. None of this happens during the SIU investigation phase, regardless of how aggressive the investigation looks.
The prosecution hasn’t committed yet. Once the DA’s office files charges, the prosecution has a public position to defend. Withdrawing or significantly reducing charges later becomes politically harder. During the pre-charging phase, the DA’s office has not committed publicly, and a well-presented defense case can result in declination, reduction to a non-criminal disposition, or referral back for additional investigation.
Evidence is still gathering, not yet locked in. Defense investigation conducted during the pre-charging phase can develop alternative explanations for the SIU’s evidence, identify witnesses the SIU missed, obtain expert opinions on disputed elements (medical opinions on contested injuries, accident reconstruction, forensic accounting), and present this information to the DA’s office before charging decisions are made. The same evidence presented after charges file is still useful, but it’s significantly more friction to walk a prosecutor back from a filed case than to talk them out of filing one in the first place.
The strategic priorities during this phase typically include presenting evidence of good-faith conduct, contesting the dollar amount of the alleged loss (which often affects whether the case is filed as a misdemeanor or felony), demonstrating the absence of intent indicators the SIU has cited, and developing the materiality challenge where it applies. Each of these arguments lands differently when made pre-filing than post-filing.
When the Investigation Becomes a Criminal Case
At some point, the SIU file may get referred to the CDI Fraud Division. At some point, the CDI file may get referred to the DA. At some point, the DA may decide to file. Each of these transitions changes the case.
Signals that an investigation may be transitioning to criminal status:
- A contact from a CDI investigator (as opposed to an SIU investigator from a private carrier). CDI involvement signals that the case has progressed past the carrier’s internal review.
- A subpoena for documents, financial records, medical records, or testimony. Subpoenas are typically associated with formal legal proceedings, including pre-filing investigations by prosecuting agencies.
- An interview request from a peace officer identifying themselves as a member of the DA’s Bureau of Investigation, a Sheriff’s investigator, or a similar law enforcement role.
- Notice of an examination under oath scheduled at a court reporter’s office with formal procedural requirements.
- A target letter from the District Attorney’s Office indicating that the recipient is the subject of a criminal investigation.
Each of these signals warrants immediate attorney involvement if it hasn’t already happened. The window between these signals and the filing of a complaint may be short.
Why Calling a Murrieta Insurance Fraud Defense Attorney Early Matters
If your insurance company has accused you of fraud — denied your claim citing suspected misrepresentation, opened an SIU file, requested a recorded statement, or referred your case to CDI — the work that matters most happens now, not after a criminal complaint is filed.
Three windows are particularly critical:
Before any recorded statement or examination under oath. The single most consequential decision in any insurance fraud accusation is whether to give a recorded statement and how to prepare if one is required. Statements made without counsel almost universally hurt the case if it progresses to criminal charges. Coordinate with counsel before any statement is given.
Before the case is referred to CDI or the DA. The pre-referral window is the strongest opportunity to influence the trajectory. Defense engagement with the carrier’s SIU, presentation of exculpatory information, and challenges to the SIU’s analysis can sometimes prevent referral entirely. Once the file moves to CDI or the DA, the same arguments are still available but with more institutional friction.
Before any charging decision. If the case has reached the DA’s office, the period before the formal complaint filing is the last and most valuable pre-charging window. Pre-filing engagement with the DA — presenting good-faith conduct evidence, contesting loss amounts, demonstrating absence of intent — can result in declination, misdemeanor filing in lieu of felony, or referral back for additional investigation.
For licensed professionals — before anything. Medical professionals, contractors, real estate agents, insurance brokers, attorneys, and others holding California professional licenses face automatic licensing board review when criminal charges are filed. Coordinating defense strategy between criminal counsel and licensing defense counsel from the earliest stage of the SIU investigation often determines whether the license survives.
If your insurance carrier has accused you of submitting a false claim in Southwest Riverside County — Murrieta, Temecula, Menifee, Lake Elsinore, Wildomar, Winchester, Canyon Lake, or French Valley — decline to engage substantively with SIU investigators, preserve all documentation related to the claim, and contact counsel before any recorded statement or formal interview.
