Business fraud is an umbrella term for deceptive commercial or financial conduct used to gain an unfair advantage. In California, certain fraud involving public funds or government programs can trigger specific civil and criminal laws, and some situations may also involve whistleblower protections for people who report wrongdoing.
Common examples include embezzlement, misrepresenting facts to investors, and manipulating financial records. Because many fraud claims require proof that the other party intended to mislead you, gathering strong documentation and other evidence is often essential to building a successful case.
Key Evidence Used to Prove Business Fraud
To show a party’s intent to commit business fraud, an attorney must analyze many different types of evidence. Some examples of evidence that can help prove business fraud include:
Contracts and Agreements
By comparing a contract to a business’s stated intent, you can highlight terms that are out of line with or completely incompatible with its promises.
Emails, Texts, and Correspondence
Written messages can serve as hard proof of intent to deceive or serve as circumstantial evidence of what the liable party knew and when.
Financial Records
Inconsistencies between a company’s internal records and what it told investors or customers can support claims of securities fraud or other forms of financial manipulation.
Marketing and Promotional Materials
Advertisements or promotional materials featuring false or misleading information can help establish an intent to commit business fraud, especially if the company later attempts to downplay or conceal earlier promises.
Internal Company Documents
Private business records and messages may reveal different financial information than the company has publicly presented, and could suggest that certain representatives were aware of these discrepancies in advance.
Witness Testimony
If a whistleblower is willing to share firsthand information about fraudulent activity within a company, their testimony can provide powerful support for your case.
Expert Reports
Your attorney can ask a relevant expert to analyze the evidence and write a report stating their professional opinion on whether it proves business fraud, potentially strengthening your claims.
Digital Evidence
Metadata from company documents, usage logs from devices such as computers and phones, and other digital records can help reveal suspicious activity and support an argument that the conduct was intentional.
Why Evidence Is Critical in a Business Fraud Case
In a business fraud case, the burden of proof is on the victim to establish each required element, including:
- The business made a false statement about a material fact
- The business knew the statement was false (or acted with reckless disregard for the truth)
- The business intended to induce the victim to rely on the statement
- The victim justifiably relied on the statement when deciding to act or not act
- The victim suffered compensable damages caused by that reliance
Because the victim must prove every element, a defendant can defeat the claim by showing that even one element is not met. A well-supported case that includes solid documentation, consistent testimony, and credible expert analysis can strengthen the claim and help it move forward more efficiently.
Burden of Proof in Fraud Cases
In a civil business fraud case, the plaintiff generally must prove the claim by a preponderance of the evidence. This means it is more likely than not that fraud occurred based on the facts. This is a lower standard than in criminal cases, where prosecutors typically must prove guilt beyond a reasonable doubt to obtain a conviction.
Role of Intent and Reliance
For a claim based on intentional misrepresentation, the plaintiff generally must show the defendant meant to mislead them. The plaintiff must also prove they suffered losses because they justifiably relied on the false or misleading statements.
Because direct “smoking gun” proof of intent is uncommon, lawyers typically piece together emails, records, and other documentation to show the deception was more likely deliberate than an honest mistake. And even if the misconduct seems obvious in hindsight, the plaintiff still has to demonstrate their reliance was reasonable under the circumstances. If a case falls short on either intent or justifiable reliance, the fraud claim can fail.
How to Gather and Preserve Evidence of Business Fraud
Whether you’re a defrauded small business or a whistleblower who has uncovered illegal behavior within your company, gathering and preserving evidence is crucial to successfully holding the perpetrators accountable. Some tips for properly obtaining and storing key records include:
- Take thorough notes: Recording when, where, and how you witness or uncover fraud can help fill any gaps left by other evidence later.
- Save records as you come across them: Keep and organize any documents related to your relationship with the company you suspect of fraud. Preserve new records whenever they’re available to save time and hassle later.
- Preserve communications: Save any written messages between you and the company, including emails, texts, or memoranda. If relevant information is discussed in person or over the phone, take contemporaneous notes after and consider emailing a summary to create a paper trail.
- Be aware of privacy laws: California generally requires all parties’ consent to record confidential communications. Recording or obtaining evidence improperly can create serious issues for your case later on.
- Talk to a lawyer: An experienced California deceptive business practices attorney can help you identify and gather further evidence to support your claims, then assemble a strong case from all available information.
Common Mistakes That Can Weaken a Fraud Case
Seemingly minor missteps can make it much more difficult to pursue a business fraud case. Common mistakes made by small businesses include:
- Waiting to take action: In California, fraud claims often must be filed within three years of when the fraud was discovered, or reasonably should have been discovered. Waiting to take action can make a case harder to prove because documents can be lost, memories can fade, and key evidence may become more difficult to obtain. Missing the deadline can also bar your claim entirely.
- Not performing diligence: If you don’t make a cursory effort to avoid being defrauded, it will be hard to successfully sue for fraud afterward. Make sure not to take a business’s claims at face value before doing a deal, as proving you acted responsibly is a key element of a business fraud claim.
- Failing to properly retain records: If you lost or deleted documents that could help you prove your case, a business that engages in fraud probably isn’t going to help you out by sending new copies. Make sure to keep all relevant business records well-organized and accessible in case you need them later.
