Corporate Investigations: When Does a Business Need an Investigator?
Corporate investigations help clarify fraud, theft, partners, employees and risks before a business decision. A guide to choosing a corporate investigator and running a lawful, focused investigation.
In short
A corporate investigation fills in missing information for a decision, or clarifies a suspicion inside business activity. It can address fraud, theft, conflicts of interest, partners, suppliers, employees or locating information. Before starting, define a clear question, choose a licensed investigator with business experience and involve a lawyer when the investigation relates to a dispute or legal proceedings.
- Define a clear business question before opening the investigation
- Verify the investigator is licensed and experienced in corporate work
- Consider legal advice before sensitive steps
What is a corporate investigation?
A corporate investigation is a process of gathering and checking information to clarify an event, a suspicion or a risk related to a business.
The goal can be preventing damage, clarifying something that already happened, or informing a decision ahead of a significant transaction.
When does a business turn to an investigator?
- Suspected theft or embezzlement
- Fraud by an employee, supplier or external party
- Conflicts of interest
- A background check before a significant engagement
- Locating a person or assets
- A partners' dispute
- Fact-finding ahead of legal proceedings
- Suspected information leaks
Not every suspicion justifies a broad investigation.
Define the business question
Instead of "we don't trust him", prefer: "we need to establish whether a business connection exists between the employee and a specific supplier."
A clear question enables a shorter, more precise investigation.
Internal check or an external investigator?
Sometimes you can start with an internal review of material the business lawfully holds.
When private-investigation work, field work, external information or independence is required, it may be time to involve a licensed investigator.
Background checks before a deal
A check can compare details that were provided against lawful, public sources, examine relevant business connections and flag information that justifies further inquiry.
A background check is not a guarantee that the deal is safe.
Employee investigations and suspected embezzlement
An unplanned investigation can expose the very fact of the check, damage evidence or create privacy and labor-law problems.
In sensitive cases, involve legal advice before significant steps.
Trade secrets and information leaks
Don't assume that information "belonging to the business" permits any method of monitoring or account access. Authorization and the law matter.
What does a corporate investigation deliver?
- Information mapping
- A report
