Five Common Discovery Mistakes that Cost Defendants in Louisiana Courts

The discovery phase of a lawsuit, when both sides exchange information, can make or break a case. For insurance companies and corporations, small missteps during this stage can lead to major problems, including fines, sanctions, or trial losses. Knowing the most common pitfalls can help insurers and businesses protect their credibility and strengthen their defense.

One of the biggest mistakes is failing to update discovery responses when new information emerges. If a defendant learns additional facts after answering written questions or producing documents, those responses must be corrected or supplemented. Ignoring that obligation can make it appear as though the company is hiding information, leading to penalties or reputational harm.

Another problem is relying on vague or boilerplate objections. Responses that simply state, “overly broad” or “unduly burdensome,” without explaining why or whether any documents are being produced, do not comply with Louisiana law. Courts expect specific, good faith answers. When responses are too general, judges can order insurers to redo their answers or even impose fines for being uncooperative.

A third common mistake involves failing to preserve key evidence. Once a claim becomes a potential lawsuit, defendants should ensure that all relevant materials such as emails, claim notes, and internal records are saved. Deleting or losing information can lead to allegations of spoliation, meaning destruction of evidence, and the court may assume the missing material would have hurt the insurer’s case.

Insurers and corporations also often misunderstand what parts of their internal files are protected by privilege. While attorney communications are generally confidential, not every internal document qualifies. Claims handling notes, adjuster emails, and internal guidelines may be discoverable. Overusing privilege objections or refusing to produce such materials can backfire, resulting in subpoenas, sanctions, or arguments that the insurer acted in bad faith.

Finally, many defendants run into trouble with expert witnesses. Courts require parties to disclose their experts on time, describe their opinions, and provide the data or documents the experts relied on. Missing these deadlines or offering incomplete disclosures can lead the court to limit or exclude the expert’s testimony, which can seriously weaken a defense strategy.

Success in discovery depends on diligence, transparency, and organization. Defendants can avoid most problems by keeping thorough records, responding promptly and completely, updating answers when new facts arise, using privilege carefully and honestly, and staying on top of expert disclosures deadlines. This ensures compliance and builds credibility with the court, which can be a key advantage in any litigation.
