Navigating parallel civil and criminal SEC investigations

On Behalf of | Sep 1, 2026 | Criminal Defense, Federal Criminal Defense

In Hawaiʻi’s close-knit investment community, an SEC inquiry can raise concerns beyond a civil case. You may enter a deposition expecting routine questions about a business deal, then learn that your answers could matter in a criminal case. That risk can arise before anyone mentions the DOJ or criminal charges. 

Here is what you should know about the link between an SEC inquiry, your testimony and federal prosecution.

A civil SEC investigation can create criminal exposure

An SEC investigation can uncover facts that later matter to federal prosecutors, even when the SEC seeks only civil remedies. The SEC and DOJ have different roles, but they can look at the same conduct. Facts found during the civil inquiry can then take on greater importance if the conduct may also violate federal criminal law.

How deposition statements can become evidence in a federal case

What you say under oath can give prosecutors facts they may later use in a criminal case. You do not need to admit wrongdoing for your words to create a problem. An answer could set a timeline, explain what you knew or clash with evidence found later. Even a small difference between your testimony and other evidence can draw attention. Those details can help prosecutors link facts and support an indictment.

The Fifth Amendment becomes more complicated in a civil proceeding

The Fifth Amendment can protect you from answering a question that could incriminate you, but using that right in a civil case can bring other concerns. Unlike a person facing criminal charges, you may still need to take part in the civil matter after you claim the privilege. The right can give you an important safeguard, but deciding when to use it calls for care.

Civil and criminal strategies cannot be separated

When the same conduct raises civil and criminal concerns, your choices during the SEC inquiry should account for both. Your answers may affect the civil case while also creating issues for a possible criminal defense. Looking at both sides before you respond can help you avoid solving one problem while creating another.

Protect your position before the stakes rise

If you face an SEC inquiry that could lead to criminal charges, review the subpoena, planned testimony and key facts with an attorney before you answer major questions. Legal guidance can help you assess the risks and decide how to protect your rights. Early advice can also help you prepare for questions that may have both civil and criminal consequences.
